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. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10034-20-5, help many people in the next few years., Application of 10034-20-5

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.

Synthesis of antimitotic thioglycosides: In vitro and in vivo evaluation of their anticancer activity

The synthesis and biological activity of oleylN-acetyl-alpha- and beta-d-glucosaminides (1 and 2, respectively) and their thioglycosyl analogues (3 and 4, respectively) are reported. The compounds exhibited antimitotic activity on rat glioma (C6) and human lung carcinoma (A549) cell cultures in the micromolar range. Analysis of cell extracts using ultra performance liquid chromatography-mass spectrometry showed that the synthetic glycosides produce alterations in glycosphingolipid metabolism, with variable effect on the level of glucosylceramide depending on the configuration of the antimitotic used. In vivo experiments in nude mice bearing an implanted C6 glioma showed that the alpha-thioglycoside 3 reduced tumor volume, while the O-glycosyl derivative was inactive, highlighting the importance of using enzyme resistant glycosides.

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.
