Bis[μ-bis­(2,6-diiso­propyl­phen­yl) phosphato-κ2O:O']bis­[(2,2'-bi­pyridine-κ2N,N')lithium] toluene disolvate and its catalytic activity in ring-opening polymerization of ∊-caprolactone and l-dilactide

The solvated centrosymmmtric title compound, [Li2(C24H34O4P)2(C10H8N2)2]·2C7H8, was formed in the reaction between {Li[(2,6-iPr2C6H3-O)2POO](MeOH)3}(MeOH) and 2,2'-bi­pyridine (bipy) in toluene. The structure has monoclinic (P21/n) symmetry at 120 K and the asymmetric unit consists of half a complex mol­ecule and one mol­ecule of toluene solvent. The diaryl phosphate ligand demonstrates a μ-κO:κO'-bridging coordination mode and the 2,2'-bi­pyridine ligand is chelating to the Li+ cation, generating a distorted tetra­hedral LiN2O2 coordination polyhedron. The complex exhibits a unique dimeric Li2O4P2 core. One isopropyl group is disordered over two orientations in a 0.621 (4):0.379 (4) ratio. In the crystal, weak C—H⋯O and C—H⋯π inter­actions help to consolidate the packing. Catalytic systems based on the title complex and on the closely related complex {Li[(2,6-iPr2C6H3-O)2POO](MeOH)3}(MeOH) display activity in the ring-opening polymerization of ∊-caprolactone and l-dilactide.

Crystal structure and photoluminescence properties of catena-poly[[bis­(1-benzyl-1H-imidazole-κN3)cadmium(II)]-di-μ-azido-κ4N1:N3]

The new title one-dimensional CdII coordination polymer, [Cd(C10H10N2)2(μ1,3-N3)2]n, has been synthesized and structurally characterized by single-crystal X-ray diffraction. The asymmetric unit consists of a CdII ion, one azide and one 1-benzyl­imidazole (bzi) ligand. The CdII ion is located on an inversion centre and is surrounded in a distorted octa­hedral coordination sphere by six N atoms from four symmetry-related azide ligands and two symmetry-related bzi ligands. The CdII ions are linked by double azide bridging ligands within a μ1,3-N3 end-to-end (EE) coordination mode, leading to a one-dimensional linear structure extending parallel to [100]. The supra­molecular framework is stabilized by the presence of weak C—H⋯N inter­actions, π–π stacking [centroid-to-centroid distance of 3.832 (2) Å] and C—H⋯π inter­actions between neighbouring chains.

The CoN6 moiety shows distortion from regular octa­hedral geometry with the trans bond angles of two N—Co—N units being 160.62 (9)°. In the crystal, O—H⋯Cl and C—H⋯O inter­actions link the components into (001) sheets. The title compound exhibits blue-light emission, as indicated by photoluminescence data, and a HOMO–LUMO energy separation of 2.23 eV was obtained from its diffuse reflectance spectrum.

A redetermination of the crystal structure of the mannitol complex NH4[Mo2O5(C6H11O6)]·H2O: hydrogen-bonding scheme and Hirshfeld surface analysis

The redetermined structure [for the previous study, see: Godfrey & Waters (1975). Cryst. Struct. Commun. 4, 5–8] of ammonium μ-oxido-μ-[1,5,6-tri­hydroxy­hexane-2,3,4-tris­(olato)]bis­[dioxidomolybdenum(V)] monohydrate, NH4[Mo2(C6H11O6)O5]·H2O, was obtained from an attempt to prepare a glutamic acid complex from the [Co2Mo10H4O38]6− anion. Subsequent study indicated the complex arose from a substantial impurity of mannitol in the glutamic acid sample used. All hydrogen atoms have been located in the present study and the packing displays N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds. A Hirshfeld surface analysis was also performed.

Isomorphism: `molecular similarity to crystal structure similarity' in multicomponent forms of analgesic drugs tolfenamic and mefenamic acid

The non-steroidal anti-inflammatory drugs mefenamic acid (MFA) and tolfenamic acid (TFA) have a close resemblance in their molecular scaffold, whereby a methyl group in MFA is substituted by a chloro group in TFA. The present study demonstrates the isomorphous nature of these compounds in a series of their multicomponent solids. Furthermore, the unique nature of MFA and TFA has been demonstrated while excavating their alternate solid forms in that, by varying the drug (MFA or TFA) to coformer [4-di­methyl­amino­pyridine (DMAP)] stoichiometric ratio, both drugs have produced three different types of multicomponent crystals, viz. salt (1:1; API to coformer ratio), salt hydrate (1:1:1) and cocrystal salt (2:1). Interestingly, as anticipated from the close similarity of TFA and MFA structures, these multicomponent solids have shown an isomorphous relation. A thorough characterization and structural investigation of the new multicomponent forms of MFA and TFA revealed their similarity in terms of space group and structural packing with isomorphic nature among the pairs. Herein, the experimental results are generalized in a broader perspective for predictably identifying any possible new forms of comparable compounds by mapping their crystal structure landscapes. The utility of such an approach is evident from the identification of polymorph VI of TFA from hetero-seeding with isomorphous MFA form I from acetone–methanol (1:1) solution. That aside, a pseudopolymorph of TFA with di­methyl­formamide (DMF) was obtained, which also has some structural similarity to that of the solvate MFA:DMF. These new isostructural pairs are discussed in the context of solid form screening using structural landscape similarity.

Alexion's Buyout of Portola Pharmaceuticals Gets Investors' Blood Flowing

Source: Streetwise Reports   05/05/2020

Shares of Portola Pharmaceuticals traded 130% higher after the company reported that it has received an $18 per share buyout offer from Alexion Pharmaceuticals.

Commercial-stage biotechnology company Portola Pharmaceuticals Inc. (PTLA:NASDAQ), which focuses on blood-related disorders, and global biopharmaceuticals firm Alexion Pharmaceuticals Inc. (ALXN:NASDAQ) announced that they have entered into a definitive merger agreement for Portola to be acquired by Alexion.

The acquisition is said to provide a key addition to Alexion's diversified commercial portfolio. The report indicated that the merger agreement has already been unanimously approved each of the company's boards of directors.

The report explained that "Portola's commercialized medicine, Andexxa® [coagulation factor Xa (recombinant), inactivated-zhzo], marketed as Ondexxya® in Europe, is the first and only approved Factor Xa inhibitor reversal agent, and has demonstrated transformative clinical value by rapidly reversing the anticoagulant effects of Factor Xa inhibitors rivaroxaban and apixaban in severe and uncontrolled bleeding."

Portola's President and CEO Scott Garland commented, "In developing and launching Andexxa, Portola has established a strong foundation for changing the standard of care for patients receiving Factor Xa inhibitors that experience a major, life-threatening bleed. Andexxa rapidly reverses the pharmacologic effect of rivaroxaban and apixaban within two minutes, reducing anti-Factor Xa activity by 92 percent...Given their enhanced resources, global footprint and proven commercial expertise, we look forward to working with Alexion to maximize the value of Andexxa. With their commitment to commercial excellence, together, we will be able to drive stronger utilization of Andexxa, increase penetration and accelerate adoption in the critical care setting."

Ludwig Hantson, Ph.D., CEO of Alexion, remarked, "The acquisition of Portola represents an important next step in our strategy to diversify beyond C5. Andexxa is a strategic fit with our existing portfolio of transformative medicines and is well-aligned with our demonstrated expertise in hematology, neurology and critical care...We believe Andexxa has the potential to become the global standard of care for patients who experience life-threatening bleeds while taking Factor Xa inhibitors apixaban and rivaroxaban. By leveraging Alexion's strong operational and sales infrastructure and deep relationships in hospital channels, we are well positioned to expand the number of patients helped by Andexxa, while also driving value for shareholders."

The firms advised that "under the terms of the merger agreement, a subsidiary of Alexion will commence a tender offer to acquire all of the outstanding shares of Portola's common stock at a price of $18 per share in cash." Alexion plans to fund the purchase with existing cash on hand and the transaction is expected to close in Q3/20. The purchase is subject to approval by a majority interest of Portola's common stockholders tendering their shares along with ordinary closing conditions and regulatory approvals. The company noted that "following successful completion of the tender offer, Alexion will acquire all remaining shares not tendered in the offer at the same price of $18 per share through a merger."

Alexion is a global biopharmaceutical company based in Boston, Mass., with offices in 50 countries worldwide. The company states that it has been "the global leader in complement biology and inhibition for more than 20 years and that it has developed and commercializes two approved complement inhibitors to treat patients with paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome, as well as the first and only approved complement inhibitor to treat anti-acetylcholine receptor antibody-positive generalized myasthenia gravis and neuromyelitis optica spectrum disorder."

Portola is headquartered in South San Francisco, Calif., and is a commercial-stage biopharmaceutical company focused on treating patients with serious blood-related disorders. Specifically, the company is engaged in developing and commercializing novel therapeutics in order to advance the fields of thrombosis and other hematologic conditions. The firm listed that its first two commercialized products are Andexxa® and Bevyxxa® (betrixaban), and that it is also advancing and developing cerdulatinib, a SYK/JAK inhibitor for use in treatment of hematologic cancers.

Portola Pharmaceuticals started off the day with a market capitalization of around $609.0 million with approximately 78.5 million shares outstanding and a short interest of about 23.0%. PTLA shares opened 130% higher today at $17.85 (+$10.09, +130.03%) over yesterday's $7.85 closing price. The stock has traded today between $17.71 and $17.91 per share and is currently trading at $17.83 (+$10.07, +129.77%).
