Structurally diverse copper(II)-carboxylato complexes: Neutral and ionic mononuclear structures and a novel binuclear structure

The copper complexes with the commercial auxin herbicides MCPA, 2,4-D, and 2,4,5-T in the presence of a nitrogen donor heterocyclic ligand, phen or bipyam, were prepared and characterized. The available evidence supports a dimeric structure for the 2,4-D complex in the presence of bipyam while phen leads to monomeric forms. The EPR spectrum of Cu2(2,4-D)4(bipyam)2 at 4 K in the solid state exhibits an axial signal which corresponds to almost isolated S = 1/2 magnetic ions. Magnetic data for the dimer show a weak antiferromagnetic interaction between the two metal ions with J = -0.8 cm-1. The crystal structures of tetrakis[(2,4-dichlorophenoxy)acetato]bis(2,2′-bipyridylamine)dicopper(II), 1, bis(1,10-phenanthroline)[(2,4,5-trichlorophenoxy)acetato]copper(II) chloride, 2, and aqua(1,10-phenanthroline)bis[((2-methyl-4-chlorophenoxyacetato]copper(II), 3, were determined and refined by least-squares methods using three-dimensional MoKalpha data. 1 crystallizes in space group P1, in a cell of dimensions a = 10.813(1) A, b = 12.138(1) A, c = 11.909(1) A, alpha = 86.448(3), beta = 80.127(3), and gamma = 63.982(3), and V = 1383.7(2) A3, with Z = 1.2 crystallizes in space group I2/a, in a cell of dimensions a = 29.958(9) A, b = 11.342(3) A, c = 21.196(7) A, beta = 107.94(1), and V = 6852.2(4) A3, with Z = 8. 3 crystallizes in space group P1, in a cell of dimensions a = 8.7419(8) A, b = 12.512(1) A, c = 14.598(1) A, alpha = 110.737(1), beta = 95-742(2), gamma = 103.286(2), V = 1424.1(2) A3, with Z = 2.

Evolution of a Manufacturing Route to Omarigliptin, A Long-Acting DPP-4 Inhibitor for the Treatment of Type 2 Diabetes

Development of a convergent synthesis of omarigliptin (MK-3102) suitable for commercial manufacture is described. The target molecule is assembled through a diastereoselective reductive amination of a highly functionalized pyranone with a mesylated pyrazole followed by deprotection of a Boc group. The synthesis of the pyranone relies on three Ru-catalyzed reactions: (1) a DKR reduction of a rac-alpha-aminoketone to set the two contiguous stereogenic centers, (2) a cycloisomerization of a bis-homopropargylic alcohol to a dihydropyran, and, finally, (3) a Ru-catalyzed oxidation of a pyranol to the desired pyranone. The regioselective synthesis of a N-Boc-1-mesyl pyrazole fragment was achieved via base-promoted mesyl group isomerization to afford 30:1 selectivity. A highlight of the endgame process development is telescoping a Boc deprotection and reductive amination followed by direct crystallization of the penultimate from the reaction mixture. This avoids handling of an unstable, mutagenic 1-mesylpyrazole BSA salt used in the earlier multikilogram deliveries and improves the overall diastereoselectivity and efficiency of the route.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C16H19F2NO4, you can also check out more blogs about951127-25-6

Structurally diverse manganese(II)-diclofenac complexes showing enhanced antioxidant activity and affinity to serum albumins in comparison to sodium diclofenac

The interactions of MnII ions with the nonsteroidal anti-inflammatory drug sodium diclofenac in the presence of 1,10-phenanthroline and 2,2′-dipyridylamine lead to the formation of the trinuclear [Mn3(diclofenac)6(1,10-phenanthroline)2(MeOH)] (1) and the mononuclear [Mn(diclofenac)2(2,2′-dipyridylamine)] (2), respectively, which have been characterized by X-ray crystallography. Three different coordination modes of the diclofenac ligands exist in 1, whereas the bidentate chelating mode is observed in 2. In the initial evaluation of their biological properties and potential applications, the complexes exhibited good binding propensity to human or bovine serum albumin proteins and have relatively high binding constants. The ability of the compounds to scavenge 1,1-diphenylpicrylhydrazyl, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), and hydroxyl radicals was evaluated, and 1 was the most-effective scavenger among 1, 2, and sodium diclofenac.

Design, synthesis, and biological evaluation of 1,8-naphthyridine glucosamine conjugates as antimicrobial agents

In the quest for discovering potent antimicrobial agents with lower toxicity, we envisioned the design and synthesis of nalidixic acid-D-(+)-glucosamine conjugates. The novel compounds were synthesized and evaluated for their in vitro antimicrobial activity against Gram positive bacteria, Gram negative bacteria and fungi. Cytotoxicity using MTT assay over L6 skeletal myoblast cell line, ATCC CRL-1458 was carried out. In vitro antimicrobial assay revealed that 1-ethyl-7-methyl-4-oxo-N-(1,3,4,6-tetra-O-acetyl-2-deoxy-D-glucopyranose-2-yl)-[1,8]-naphthyridine-3-carboxamide (5) and 1-ethyl-7-methyl-4-oxo-N-(2-deoxy-D-glucopyranose-2-yl)-[1,8]-naphthyridine-3-carboxamide(6) possess growth inhibitory activity against resistant Escherichia coli NCTC, 11954 (MIC 0.1589 mM) and Methicillin resistant Staphylococcus aureus ATCC, 33591 (MIC 0.1589 mM). Compound (5) was more active against Listeria monocytogenes ATCC 19115 (MIC 0.1113 mM) in comparison with the reference nalidixic acid (MIC 1.0765 mM). Interestingly, compound (6) had potential antifungal activity against Candida albicans ATCC 10231 (MIC <0.0099 mM). Remarkably, the tested compounds had low cytotoxic effect. This study indicated that glucosamine moiety inclusion into the chemical structure of the marketed nalidixic acid enhances antimicrobial activity and safety.

Formation of Optically Active (bipy = 2,2′-bipyridyl) by Photodissociation of Cl2 in Dichloromethane

An optically active bis-chelated complex, (bipy = 2,2′-bipyridyl), has been obtained when enantiomeric Cl2 was illuminated by visible light in dichloromethane.From the dependence of the optical purity of the product on light intensity, it is proposed that the reaction from Delta-Cl2 to Delta- (chirality retention) proceeds by way of the dissociation of a monodentate ligand, bipy*, from a photoactivated intermediate, Delta-Cl in the dark, while the reaction to Lambda- (chirality inversion) involves the further photoactivated configurational change of Delta-Cl to Lambda-Cl.Racemization is avoided under the conditions of weak light and high temperature.The synthetic value of optically active as a chiral intermediate has been exemplified by preparing a new chiral amphiphilic ruthenium(II) complex.
