A 1:1 flavone cocrystal with cyclic trimeric perfluoro-o-phenyl­enemercury

The title compound, systematic name tris­(μ2-perfluoro-o-phenyl­ene)(μ2-3-phenyl-4H-chromen-4-one)-triangulo-trimercury, [Hg3(C6F4)3(C15H10O2)], crystallizes in the monoclinic P21/n space group with one flavone (FLA) and one cyclic trimeric perfluoro-o-phenyl­enemercury (TPPM) mol­ecule per asymmetric unit. The FLA mol­ecule is located on one face of the TPPM acceptor and is linked in an asymmetric coordination of its carbonyl oxygen atom with two Hg centers of the TPPM macrocycle. The angular-shaped complexes pack in zigzag chains where they stack via two alternating TPPM–TPPM and FLA–FLA stacking patterns. The distance between the mean planes of the neighboring TPPM macrocycles in the stack is 3.445 (2) Å, and that between the benzo-γ-pyrone moieties of FLA is 3.328 (2) Å. The neighboring stacks are inter­digitated through the shortened F⋯F, CH⋯F and CH⋯π contacts, forming a dense crystal structure.

Crystal structures of the isomeric dipeptides l-glycyl-l-me­thio­nine and l-me­thionyl-l-glycine

The oxidation of me­thionyl peptides can contribute to increased biological (oxidative) stress and development of various inflammatory diseases. The conformation of peptides has an important role in the mechanism of oxidation and the inter­mediates formed in the reaction. Herein, the crystal structures of the isomeric dipeptides Gly-Met (Gly = glycine and Met = me­thio­nine) and Met-Gly, both C7H14N2O3S, are reported. Both mol­ecules exist in the solid state as zwitterions with nominal proton transfer from the carb­oxy­lic acid to the primary amine group. The Gly-Met mol­ecule has an extended backbone structure, while Met-Gly has two nearly planar regions kinked at the C atom bearing the NH3 group. In the crystals, both structures form extensive three-dimensional hydrogen-bonding networks via N—H⋯O and bifurcated N—H⋯(O,O) hydrogen bonds having N⋯O distances in the range 2.6619 (13)–2.8513 (13) Å for Gly-Met and 2.6273 (8)–3.1465 (8) Å for Met-Gly.

Synthesis, spectroscopic analysis and crystal structure of (N-{2-[(2-amino­eth­yl)amino]­eth­yl}-4'-methyl-[1,1'-biphenyl]-4-sulfonamidato)tri­carb­on­ylrhenium(I)

The title compound, [Re(C17H22N3O2S)(CO)3] is a net neutral fac-Re(I)(CO)3 complex of the 4-methyl­biphenyl sulfonamide derivatized di­ethyl­enetri­amine ligand. The NNN-donor monoanionic ligand coordinates with the Re core in tridentate fashion, establishing an inner coordination sphere resulting in a net neutral complex. The complex possesses pseudo-octa­hedral geometry where one face of the octa­hedron is occupied by three carbonyl ligands and the other faces are occupied by one sp2 nitro­gen atom of the sulfonamide group and two sp3 nitro­gen atoms of the dien backbone. The Re—Nsp2 bond distance, 2.173 (4) Å, is shorter than the Re—Nsp3 bond distances, 2.217 (5) and 2.228 (6) Å, and is similar to the range reported for typical Re—Nsp2 bond lengths (2.14 to 2.18 Å).

Crystal structure of tricarbon­yl[η4-6-exo-(tri­phenyl­phosphino)cyclo­hepta-2,4-dien-1-one]iron(0) tetra­fluoro­borate

The mol­ecular structure of tricarbon­yl[η4-6-exo-(tri­phenyl­phosphino)cyclo­hepta-2,4-dien-1-one]iron(0) tetra­fluoro­borate di­chloro­methane hemisolvate, [Fe(C28H22O4)(CO)3]BF4·0.5CH2Cl2, as determined by single-crystal X-ray diffraction is reported. The two independent tricarbon­yl[η4-6-exo-(tri­phenyl­phosphino)cyclo­hepta-2,4-dien-1-one] iron(0) cations and their corresponding anions form dimers, which constitute the asymmetric unit of the structure parallel to the (100) plane. Solid-state stability within that asymmetric unit as well as between neighboring dimeric units is afforded by C—H⋯O and C—H⋯F hydrogen bonds and C—H⋯π and Y—X⋯π (Y = B, C; X = F, O) inter­actions, which yield diperiodic sheets and a three-dimensional extended network.

Synthesis, crystal structure and photophysical properties of a dinuclear MnII complex with 6-(di­ethyl­amino)-4-phenyl-2-(pyridin-2-yl)quinoline

A new quinoline derivative, namely, 6-(di­ethyl­amino)-4-phenyl-2-(pyridin-2-yl)quinoline, C24H23N3 (QP), and its MnII complex aqua-1κO-di-μ-chlorido-1:2κ4Cl:Cl-di­chlorido-1κCl,2κCl-bis­[6-(di­ethyl­amino)-4-phenyl-2-(pyridin-2-yl)quinoline]-1κ2N1,N2;2κ2N1,N2-dimanganese(II), [Mn2Cl4(C24H23N3)2(H2O)] (MnQP), were synthesized. Their compositions have been determined with ESI-MS, IR, and 1H NMR spectroscopy. The crystal-structure determination of MnQP revealed a dinuclear complex with a central four-membered Mn2Cl2 ring. Both MnII atoms bind to an additional Cl atom and to two N atoms of the QP ligand. One MnII atom expands its coordination sphere with an extra water mol­ecule, resulting in a distorted octa­hedral shape. The second MnII atom shows a distorted trigonal–bipyramidal shape. The UV–vis absorption and emission spectra of the examined compounds were studied. Furthermore, when investigating the aggregation-induced emission (AIE) properties, it was found that the fluorescent color changes from blue to green and eventually becomes yellow as the fraction of water in the THF/water mixture increases from 0% to 99%. In particular, these color and intensity changes are most pronounced at a water fraction of 60%. The crystal structure contains disordered solvent mol­ecules, which could not be modeled. The SQUEEZE procedure [Spek (2015). Acta Cryst. C71, 9–18] was used to obtain information on the type and qu­antity of solvent mol­ecules, which resulted in 44 electrons in a void volume of 274 Å3, corresponding to approximately 1.7 mol­ecules of ethanol in the unit cell. These ethanol mol­ecules are not considered in the given chemical formula and other crystal data.

Synthesis, structural studies and Hirshfeld surface analysis of 2-[(4-phenyl-1H-1,2,3-triazol-1-yl)methyl]pyridin-1-ium hexa­kis­(nitrato-κ2O,O')thorate(IV)

Reaction of thorium(IV) nitrate with 2-[(4-phenyl-1H-1,2,3-triazol-1-yl)meth­yl]pyridine (L) yielded (LH)2[Th(NO3)6] or (C14H13N4)2[Th(NO3)6] (1), instead of the expected mixed-ligand complex [Th(NO3)4L2], which was detected in the mass spectrum of 1. In the structure, the [Th(NO3)6]2− anions display an icosa­hedral coordination geometry and are connected by LH+ cations through C—H⋯O hydrogen bonds. The LH+ cations inter­act via N—H⋯N hydrogen bonds. Hirshfeld surface analysis indicates that the most important inter­actions are O⋯H/H⋯O hydrogen-bonding inter­actions, which represent a 55.2% contribution.

Two new [1-(phenyl­sulfon­yl)-1H-indol-2-yl]methanamine derivatives, namely, N-(3-meth­oxy­phen­yl)-N-{[1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}acetamide, C24H22N2O4S, (I), and N-(2,5-di­meth­oxy­phen­yl)-N-{[1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}benzene­sulfonamide, C29H26N2O6S2, (II), reveal a nearly orthogonal orientation of their indole ring systems and sulfonyl-bound phenyl rings. The sulfonyl moieties adopt the anti-periplanar conformation. For both compounds, the crystal packing is dominated by C—H⋯O bonding [C⋯O = 3.312 (4)–3.788 (8) Å], with the structure of II exhibiting a larger number, but weaker bonds of this type. Slipped π–π inter­actions of anti­parallel indole systems are specific for I, whereas the structure of II delivers two kinds of C—H⋯π inter­actions at both axial sides of the indole moiety. These findings agree with the results of Hirshfeld surface analysis. The primary contributions to the surface areas are associated with the contacts involving H atoms. Although II manifests a larger fraction of the O⋯H/H⋯O contacts (25.8 versus 22.4%), most of them are relatively distal and agree with the corresponding van der Waals separations.

Crystal and mol­ecular structure of 2-methyl-1,4-phenyl­ene bis­(3,5-di­bromo­benzoate)

The aryl diester compound, 2-methyl-1,4-phenyl­ene bis­(3,5-di­bromo­benzoate), C21H12Br4O4, was synthesized by esterification of methyl hydro­quinone with 3,5-di­bromo­benzoic acid. A crystalline sample was obtained by cooling a sample of the melt (m.p. = 502 K/DSC) to room temperature. The mol­ecular structure consists of a central benzene ring with anti-3,5-di­bromo­benzoate groups symmetrically attached at the 1 and 4 positions and a methyl group attached at the 2 position of the central ring. In the crystal structure (space group Poverline{1}), mol­ecules of the title aryl diester are located on inversion centers imposing disorder of the methyl group and H atom across the central benzene ring. The crystal structure is consolidated by a network of C—H⋯Br hydrogen bonds in addition to weaker and offset π–π inter­actions involving the central benzene rings as well as the rings of the attached 3,5-di­bromo­benzoate groups.

Synthesis, crystal structure and Hirshfeld surface of ethyl 2-[2-(methyl­sulfan­yl)-5-oxo-4,4-diphenyl-4,5-di­hydro-1H-imidazol-1-yl]acetate (thio­phenytoin derivative)

The di­hydro­imidazole ring in the title mol­ecule, C20H20N2O3S, is slightly distorted and the lone pair on the tri-coordinate nitro­gen atom is involved in intra-ring π bonding. The methyl­sulfanyl substituent lies nearly in the plane of the five-membered ring while the ester substituent is rotated well out of that plane. In the crystal, C—H⋯O hydrogen bonds form inversion dimers, which are connected along the a- and c-axis directions by additional C—H⋯O hydrogen bonds, forming layers parallel to the ac plane. The major contributors to the Hirshfeld surface are C⋯H/H⋯C, O⋯H/H⋯O and S⋯H/H⋯S contacts at 20.5%, 14.7% and 4.9%, respectively.

The title complex, (1,4,7,10,13,16-hexa­oxa­cyclo­octa­decane-1κ6O)(μ-oxalato-1κ2O1,O2:2κ2O1',O2')triphenyl-2κ3C-potassium(I)tin(IV), [KSn(C6H5)3(C2O4)(C12H24O6)] or K[18-Crown-6][(C6H5)3SnO4C2], was synthesized. The complex consists of a potassium cation coordinated to the six oxygen atoms of a crown ether mol­ecule and the two oxygen atoms of the oxalatotri­phenyl­stannate anion. It crystallizes in the monoclinic crystal system within the space group P21. The tin atom is coordinated by one chelating oxalate ligand and three phenyl groups, forming a cis-trigonal–bipyramidal geometry around the tin atom. The cations and anions form ion pairs, linked through carbonyl coordination to the potassium atoms. The crystal structure features C—H⋯O hydrogen bonds between the oxygen atoms of the oxalate group and the hydrogen atoms of the phenyl groups, resulting in an infinite chain structure extending along a-axis direction. The primary inter-chain inter­actions are van der Waals forces.

In the title compound, C33H29ClN2O2, the two piperidine rings of the di­aza­bicyclo moiety adopt distorted-chair conformations. Inter­molecular C—H⋯π inter­actions are mainly responsible for the crystal packing. The inter­molecular inter­actions were qu­anti­fied and analysed using Hirshfeld surface analysis, revealing that H⋯H inter­actions contribute most to the crystal packing (52.3%). The mol­ecular structure was further optimized by density functional theory (DFT) at the B3LYP/6–31 G(d,p) level and is compared with the experimentally determined mol­ecular structure in the solid state.

Single-crystal structural analysis revealed the presence of C—H⋯N, C—H⋯Cl−, C—H⋯Se hydrogen bonds as well as chalcogen–chalcogen (Se⋯Se) and chalcogen–halogen (Se⋯Cl−) inter­actions. Non-covalent inter­actions were explored by DFT calculations followed by topological analysis of the electron density distribution (QTAIM analysis). The structure consists of pairs of seleno­diazo­lium moieties arranged in a head-to-tail fashion surrounding disordered di­chloro­methane mol­ecules. The assemblies are connected by C—H⋯Cl− and C—H⋯N hydrogen bonds, forming layers, which stack along the c-axis direction connected by bifurcated Se⋯Cl−⋯H—C inter­actions.

The title compound, [Sn(C6H5)Cl3(C12H8N2)], which was obtained by the reaction between 1,10-phenanthroline and phenyl­tin trichloride in methanol, exhibits intra­molecular hydrogen-bonding inter­actions involving the chlorine and hydrogen atoms. Crystal cohesion is ensured by inter­molecular C—H⋯Cl hydrogen bonds, as well as Y—X⋯π and π-stacking inter­actions involving three different aromatic rings with centroid–centroid distances of 3.6605 (13), 3.9327 (14) and 3.6938 (12) Å]. Hirshfeld surface analysis and the associated two-dimensional fingerprint plots reveal significant contributions from H⋯H (30.7%), Cl⋯H/H⋯Cl (32.4%), and C⋯H/H⋯C (24.0%) contacts to the crystal packing while the C⋯C (6.2%), C⋯Cl/Cl⋯C (4.1%), and N⋯H/H⋯N (1.7%) inter­actions make smaller contributions.

Crystal structure and Hirshfeld surface analyses, crystal voids, inter­molecular inter­action energies and energy frameworks of 3-benzyl-1-(3-bromoprop­yl)-5,5-di­phenyl­imidazolidine-2,4-dione

The title mol­ecule, C25H23BrN2O2, adopts a cup shaped conformation with the distinctly ruffled imidazolidine ring as the base. In the crystal, weak C—H⋯O hydrogen bonds and C—H⋯π(ring) inter­actions form helical chains of mol­ecules extending along the b-axis direction that are linked by additional weak C—H⋯π(ring) inter­actions across inversion centres. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (51.0%), C⋯H/H⋯C (21.3%), Br⋯H/H⋯Br (12.8%) and O⋯H/H⋯O (12.4%) inter­actions. The volume of the crystal voids and the percentage of free space were calculated to be 251.24 Å3 and 11.71%, respectively, showing that there is no large cavity in the crystal packing. Evaluation of the electrostatic, dispersion and total energy frameworks indicate that the stabilization is dominated by the dispersion energy.

Structure of 2,3,5-tri­phenyl­tetra­zol-3-ium chloride hemi­penta­hydrate

The title hydrated mol­ecular salt, C19H15N4+·Cl−·2.5H2O, has two tri­phenyl­tetra­zolium cations, two chloride anions and five water mol­ecules in the asymmetric unit. The cations differ in the conformations of the phenyl rings with respect to the heterocyclic core, most notably for the C-bonded phenyl ring, for which the N—C—C—C torsion angles differ by 36.4 (3)°. This is likely a result of one cation accepting an O—H⋯N hydrogen bond from a water mol­ecule [O⋯N = 3.1605 (15) Å], while the other cation accepts no hydrogen bonds. In the extended structure, the water mol­ecules are involved in centrosymmetric (H2O)2Cl2 rings as well as (H2O)4 chains. An unusual O—H⋯π inter­action and weak C—H⋯O and C—H⋯Cl hydrogen bonds are also observed.

Two new phenyl­sulfonyl­indole derivatives, namely, N-{[3-bromo-1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}-N-(4-bromo-3-meth­oxy­phen­yl)benzene­sulfonamide, C28H22Br2N2O5S2, (I), and N,N-bis­{[3-bromo-1-(phenyl­sulfon­yl)-1H-indol-2-yl]meth­yl}benzene­sulfonamide, C36H27Br2N3O6S3, (II), reveal the impact of intra­molecular π–π inter­actions of the indole moieties as a factor not only governing the conformation of N,N-bis­(1H-indol-2-yl)meth­yl)amines, but also significantly influencing the crystal patterns. For I, the crystal packing is dominated by C—H⋯π and π–π bonding, with a particular significance of mutual indole–indole inter­actions. In the case of II, the mol­ecules adopt short intra­molecular π–π inter­actions between two nearly parallel indole ring systems [with the centroids of their pyrrole rings separated by 3.267 (2) Å] accompanied by a set of forced Br⋯O contacts. This provides suppression of similar inter­actions between the mol­ecules, while the importance of weak C—H⋯O hydrogen bonding to the packing naturally increases. Short contacts of the latter type [C⋯O = 3.389 (6) Å] assemble pairs of mol­ecules into centrosymmetric dimers with a cyclic R22(13) ring motif. These findings are consistent with the results of a Hirshfeld surface analysis and together they suggest a tool for modulating the supra­molecular behavior of phenyl­sulfonyl­ated indoles.

The phenyl­acetamide moiety is nearly planar due to a weak, intra­molecular C—H⋯O hydrogen bond. In the crystal, N—H⋯O hydrogen bonds and π-stacking inter­actions between pyridazine and phenyl rings form helical chains of mol­ecules in the b-axis direction, which are linked by C—H⋯O hydrogen bonds and C—H⋯π(ring) inter­actions. A Hirshfeld surface analysis was performed, which showed that H⋯H, C⋯H/H⋯C and O⋯H/H⋯O inter­actions to dominate the inter­molecular contacts in the crystal.

NY Biopharma Shares Promising Clinical Data

Source: Dr. Ram Selvaraju 10/18/2024

Anavex Life Sciences Corp. (AVXL:NASDAQ) recently released encouraging preliminary electroencephalography (EEG) biomarker results from Part A of the ongoing Phase 2 clinical study of ANAVEX3-71 for schizophrenia treatment, according to an H.C. Wainright & Co. research note.

H.C. Wainwright & Co. analyst Dr. Ram Selvaraju, in a research report published on October 18, 2024, reiterated a Buy rating on Anavex Life Sciences Corp. (AVXL:NASDAQ) with a price target of US$40.00. The report follows Anavex's announcement of encouraging preliminary electroencephalography (EEG) biomarker results from Part A of the ongoing Phase 2 clinical study of ANAVEX3-71 for schizophrenia treatment.

Selvaraju highlighted the significance of these results, stating, "Preliminary results demonstrated a dose-dependent effect of ANAVEX3-71 on two key EEG biomarkers in patients with schizophrenia. Treatment with ANAVEX3-71 vs. placebo resulted in improvements in 40 Hz Auditory Steady-State Response (ASSR) Inter Trial Coherence (ITC) and Resting State Alpha Power."

The analyst viewed these developments positively, noting, "These results provide evidence of CNS target engagement and potential therapeutic effects of ANAVEX3-71 in schizophrenia. The observed changes reversed known EEG and ERP biomarker abnormalities associated with schizophrenia."

Regarding Anavex's lead candidate, blarcamesine, Selvaraju stated, "Anavex remains committed to completing the Marketing Authorization Application (MAA) submission to the European Medicines Agency (EMA) under the Centralized Procedure petitioning for approval of blarcamesine for treatment of Alzheimer's disease (AD) in 4Q24."

The report also highlighted Anavex's progress with other clinical programs, including a pivotal Phase 2b/3 trial in Parkinson's disease and potential trials in Rett syndrome and Fragile X Syndrome.

Selvaraju's valuation methodology for Anavex Life Sciences is based on a discounted cash flow (DCF) approach. He explained, "We utilize a discounted cash flow (DCF)-driven methodology, which ascribes a total value of roughly US$3.25B to blarcamesine alone without ascribing value to any other pipeline assets. We employ a 50% probability of approval in Rett syndrome; 60% in Parkinson's disease dementia (PDD); and 50% in AD."

The analyst added, "Further, we apply a 12% discount rate and 1% terminal growth rate. We derive a total firm value of ~US$3.4B, which yields a 12-month price objective of US$40 per share, assuming 84.8M shares outstanding as of end-F2Q25."

Selvaraju also outlined several risk factors, including potential negative clinical data, regulatory approval challenges, and commercialization difficulties.

In conclusion, H.C. Wainwright & Co.'s maintenance of a Buy rating and US$40 price target reflects a positive outlook on Anavex Life Sciences' clinical progress and potential in developing treatments for neurological disorders. The share price at the time of the report of US$5.51 represents a potential return of approximately 626% to the analyst's target price, highlighting the significant upside potential if the company's clinical development plans prove successful.

'We Need To Be Nurtured, Too': Many Teachers Say They're Reaching A Breaking Point

; Credit: /Ryan Raphael for NPR

Kavitha Cardoza | NPR

To say Leah Juelke is an award-winning teacher is a bit of an understatement. She was a top 10 finalist for the Global Teacher Prize in 2020; she was North Dakota's Teacher of the Year in 2018; and she was awarded an NEA Foundation award for teaching excellence in 2019.

But Juelke, who teaches high school English learners in Fargo, N.D., says nothing prepared her for teaching during the pandemic.

"The level of stress is exponentially higher. It's like nothing I've experienced before."

It's a sentiment NPR heard from teachers across the country. After a year of uncertainty, long hours and juggling personal and work responsibilities, many told NPR they had reached a breaking point.

Heidi Crumrine, a high school English teacher in Concord, N.H., says this has been the most challenging year she's ever encountered in her two decades of teaching.

"And I say [that] as someone who started her first day of teaching on 9/11 in the Bronx in New York City."

Teaching is one of the most stressful occupations in the U.S., tied only with nurses, a 2013 Gallup poll found. Jennifer Greif Green, an education professor at Boston University, says the additional stress teachers are reporting during the pandemic is worrying because it doesn't only affect educators — it also affects students.

"The mental health and well-being of teachers can have a really important impact on the mental health and well-being of the children who they're spending most of their days with," Green explains. "Having teachers feel safe and supported in their school environments is essential to students learning and being successful."

Lisa Sanetti, a professor of educational psychology at the University of Connecticut, says, "Chronically stressed teachers are just less effective in the classroom."

All that stress can also lead to burnout, which leads to teachers leaving the profession, Sanetti says. "And we have a huge teacher turnover problem in our country."

Districts are trying to help — with yoga classes, counseling sessions and webinars on mental health. Some teachers have organized trivia nights or online happy hours where colleagues can just vent. Teachers told NPR they force themselves to take breaks and go for a bike ride or call a friend. Some have started therapy.

But most of the educators NPR spoke with say they're so exhausted, that even self-care feels like one additional thing to do.

"The reality is, when you're living it, you're just trying to get to the end of the day successfully and try again tomorrow," Crumrine says.

"It feels like we're building the plane while we're flying it"

In March 2020, when schools moved online, teachers across the U.S. had to completely reimagine their approach to education, often with no training or time to prepare. For many, it was a rough transition.

Teachers told NPR they've spent the past year experimenting with different methods of online and hybrid teaching, while also providing tech support for their students and families. Many say they routinely work 12-hour days and on weekends, yet struggle to form relationships with children virtually. Answering emails can take two hours a day.

Rashon Briggs, who teaches high school special education in Los Angeles, spent a lot of time worrying about his students during remote learning (his district only recently started offering in-person options). "One of the biggest challenges is knowing that the kids were not getting the same level of service that they were getting in person," he says.

Teachers in districts that opened earlier for in-person learning say they have additional responsibilities now, such as sanitizing desks between classes, making sure children follow school safety protocols and keeping track of students who have had to quarantine.

"I have a calendar and it says who's quarantined, who is cleared to return on what day, who was absent," explains Rosamund Looney, who teaches first grade in Jefferson Parish, La. "Then I follow up with those families to see: 'Are you OK?' So there's just so much space taken up by that monitoring."

Looney also worries about her students' learning. Everyone in her district has to wear masks in class, which she says she completely agrees with. But those masks mean she can't see her first graders' mouths as they learn phonics.

"You are watching your teacher sound out words and then figuring out how to do that. And it's really hard for me to gauge what they are and aren't able to say." She says she's especially concerned about students who are more at risk of falling behind academically, like English learners.

In New Hampshire, Crumrine says quarantines and positive cases among school staff have led to a constant shifting between fully online and hybrid classes. The fluctuations have been exhausting for her. "We started the year remote. Then we went back to school in October, then we were remote again in November, December. We went back to hybrid [in early February]," she says. New Hampshire's governor has now ordered all schools reopen for full-time, in-person classes by this week.

"It feels like we're building the plane while we're flying it and the destination keeps changing on us," Crumrine says.

Balancing work and home life

In addition to worrying about their students, many teachers are also concerned about their own children. Crumrine, whose husband is also a teacher, has three children and says she feels pulled by competing demands.

"I feel this sense of guilt that I'm not a good enough teacher for my students and I'm not a good mother for my own kids. It just feels like a constant wave of never feeling like I can do what I know I'm good at."

Juelke, in North Dakota, is a single mom with a 9- and 3-year-old. "I'm juggling the children and making sure my daughter is in her class and my 3-year-old is entertained. And that is definitely taking a toll."

Many teachers say they are eating and drinking more, and exercising and sleeping less.

Briggs, in L.A., says his sleeping patterns are completely off. "Being awake all hours of the night, going to bed at 2, 3 a.m., drinking coffee late at night and try to finish work so I can be more prepared the next day."

He's stressed, in part, because there are no clear work-life boundaries anymore. "When you're waking up in the same space that you're on Zoom, that you're grading papers, that you're watching Netflix, those lines are blurred very easily."

Others say they're not as active at home, and they're eating more junk food and putting on weight. The tight schedules means they don't always move between classes, or even remember to drink water.

"There are a lot of dehydrated teachers out there," says Looney.

Many, like Juelke, say they miss having personal time. "That time where I could sit in the car and drive to work and just kind of relax a little, or my prep time at school alone. That's gone now. And so I feel like my mental health has struggled in that way."

She says even though it breaks her heart, she's started looking for another profession.

Leonda Archer, a middle school math teacher in Arlington, Va., says she's usually a very upbeat person, but the pandemic — coupled with the racial turmoil in the country — has taken a toll. She's African American, and says reports of Black men and women being killed by police makes her fear for her husband's safety.

"There were some points of lowness that I hadn't experienced before. There are some days where I feel like it's hard to keep going."

Archer says she has had difficulty sleeping, and doesn't have an appetite. "And right when I get into a groove, another traumatic experience happens."

Briggs says it was hard not being able to process events like George Floyd's death and the Black Lives Matter protests with his colleagues. In the past, those conversations informed what he would say in the classroom to help his own students make sense of the news.

"The teachers were not able to talk to each other about 'How do you talk about this? How do you present that?' " he says. "There was a lack of ability for us to communicate a message about social justice and rights and the wrongs."

Crumrine says she misses the social aspect of being with her students, and other teachers. "We're not eating lunch together. We're not popping into each other's classrooms. We're all in our little silos."

The school reopening divide

Teachers told NPR they feel a growing chasm in their communities: Parents want schools to open, but teachers first want to make sure it's safe. Many feel they are not being included in these conversations, and their concerns aren't being taken seriously.

Crumrine says it's been devastating hearing elected officials and parents criticize teachers, insisting that schools need to open, even though teachers are concerned about their own health. She says some community members acted like online classes meant teachers weren't working at all. In fact, she says, they were working harder than ever. "It just makes it feel so much worse when you read these horrible things that people say about us or these assumptions that they make about what we are or are not doing."

She says many states, including her own, didn't prioritize vaccines for teachers, which to her revealed just "how deep that lack of value of educators is."

Sarahi Monterrey, who teaches English learners in Waukesha, Wisc., says she's felt a "huge divide" in the community. "It almost seems like us against them." She was in a Zoom school board meeting where parents and students were present, and a teacher testified that her husband had COVID-19. "And a parent in the room said, 'Who cares?' And I was blown away. Just blown away."

In Virginia, Archer says, at the beginning of the pandemic, "We were seen as angels. Like, 'Oh my God, I've been home with my child for two months, how do teachers do it?' And now the narrative has totally flip-flopped."

She says she also misses "the vibe of school, the energy, all of that. But I don't want people to be sick."

Archer works 12-hour days, and says people need to remember that teachers are people too. "Our profession is a nurturing one, but we also are humans that need to be poured into. We need to be nurtured, too."

NYC Schools Chancellor Says Her Message To Parents Is Simple: Schools Are Safe

Students wave goodbye during dismissal at Yung Wing School P.S. 124 on March 25, 2021 in New York City.; Credit: Michael Loccisano/Getty Images

Rachel Martin | NPR

New York City schools will reopen in full this fall with no options for virtual learning.

Mayor Bill de Blasio made the announcement during an appearance Monday on MSNBC, saying, "You can't have a full recovery without full-strength schools, everyone back sitting in those classrooms."

De Blasio said the nation's largest school district will meet in person five days a week, with no remote option available. New Jersey has similar plans, and other states want to limit remote lessons as well.

While the decision in New York is being celebrated as an important milestone on the path to returning to some level of normalcy from the pandemic, some parents remain fearful about sending their children back to in-person learning.

Meisha Porter, chancellor of the New York City Department of Education, has heard those concerns firsthand, but says "our schools have been the safest place in the city."

In an interview with NPR's Morning Edition, Porter said that with New York City in the process of a full reopening, "it's important that our schools be fully open, too."

Porter said the city would not make the vaccine a requirement for staff and teachers, but said more than 70,000 employees have already received at least one dose. The city will continue to monitor the health and safety of children, teachers and staff, she said, "but we know our schools have been safe and we need our children back."


Interview Highlights

What do you say to parents who are still really worried about the virus and may not want their kids to return, especially elementary aged kids who don't have access to a vaccine?

I say what we've said over and over again. You know, this past week, we've been at 0.3% — our seven-day positivity rate. Our schools are the safest place. And I've always said nothing, absolutely nothing, replaces the interaction and the learning that happens between a student and teacher in our classrooms. And so what I say to parents, as a parent, is we're going to continue to be in conversations. We're going to continue to make decisions around health and safety. We're going to continue to do those things that parents need us to do, that I need to ensure that we do, to make sure our buildings remain safe and we can get our babies back.

Is part of that effort a consideration about making the vaccine a requirement for staff and teachers?

At this moment, we're not making it a requirement, but we are encouraging [staff and teachers to get vaccinated], and we're going to really work with the city to provide access for students and families and teachers, as we've done over the last couple of months. And so right now, we're pushing and encouraging our staff to get vaccinated. ...

But I mean, wouldn't that help if you had 100%? I mean, children are required to show proof of of immunizations of vaccines to go to school. Why not maintain the same line for teachers and staff?

... I would say this, that we are not in a place where we want to, at this moment, mandate the vaccine. We want to continue to encourage. We all know that folks have had concerns about vaccines, and we want to continue to encourage that vaccines are safe and they are effective. I've been vaccinated along with the 70,000 DOE employees that have been vaccinated. And so we're not, at the moment where we are going to require it.

Have you heard from families who've come to rely on being able to have their kids, their teenagers, working while in school? There's evidence that those with that kind of economic need are those who want to continue with remote learning or some kind of hybrid.

I can tell you that I haven't heard that from families, that they want to they want remote learning so that their teenagers can continue to work. But I know, that that may be a reality for some families. And one of the things that we're doing this summer is increasing access to summer youth employment, increasing access to our learning-to-work programs for our young people, because we know how important it is for some young people to work. But it is equally, if not more important, that they maintain learning and have a connection to a strong and sound education, and we'll continue to do that through learning to work throughout the school year.

What about those students who have found that remote learning just works better for them? I mean, whether they are kids who have struggled socially in school environments, who have been bullied or kids with learning challenges who appreciate just being able to focus away from other students in the classroom. Are there any plans to come up with ways to better address their needs in the future?

So what we're looking forward to is leveraging what we've learned from remote learning as an innovation in our system as we move forward in return. And I think that's what's going to be important for us.

Do you know what that innovation is going to look like?

It's going to look like access to courses across schools and districts, breaking down district lines and walls, high-level courses, enrichment opportunities. You know, remote learning has expanded the universe of what schools should look like.
