A novel class of potent and selective non-peptide neuropeptide Y (NPY) Y1 receptor antagonists, having benzazepine nuclei, have been designed, synthesized, and evaluated for activity. Through a blind screening we found the compound 1-N-(3-(N' -(tert-butoxycarbonyl)amino)benzyl)-7-methoxy-3-(3)-methylureido)-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (9: IC50 =1.6 μM). Chemical modifications of 9 gave a potent NPY Y1 antagonist 3-(N-(4-hydroxyphenyl)-N0 -methylguanidino)-1-N-(3-(N'-(tert- butoxycarbonyl)amino)benzyl)-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (14c: IC50 =43 nM), which had no affnity for NPY Y2 and Y5 receptors.

Nivel 1,2-Dithiins: Synthesis, Molecular Modeling Studies, and Antifungal Activity

The first structure-activity study involving the 1,2-dithiin class of compounds (1,2-dithiacyclohexadienes) is herein reported.A series of 3,6-disubstituted 1,2-dithiins was synthesized from dithiins 1d and 1e and evaluated as antifungal agents.A new and versatile synthesis of dithiins 1d and 1e is reported which is amenable to scale-up at the kilogram level.The novelty of the process derives from the use of β-mercaptopropionitrile as the thiophile, relying on a β-elimination strategy and subsequent oxidation to create the 1,2-dithiin ring.Optimal geometries of dithiins 1d, 18i, and 45 and model dithiin 61 were determined by molecular mechanics and Hartree-Fock molecular orbital calculations.Two possible mechanisms of action are presented for the 1,2-dithiin class of compounds to explain their observed antifungal activities against Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus.
