A series of aliphatic isoniazid carbo(x/thio)amides has been synthesized by a facile one-pot green method in aqueous media by harnessing microwave irradiations. In vitro antitubercular screening of the synthesized compounds against Mycobacterium tuberculosis H37Rv (MTB strain) reveals promising antimycobacterial potential with MIC in the range of 1 to 4 µg/ml.

A systematic exploration of thiophilic ability of o-iodoxybenzoic acid (IBX) for oxidative desulfurization to trigger domino reactions leading to new methodologies for synthesis of different azoles is described. A variety of highly substituted oxadiazoles, thiadiazoles, triazoles, and tetrazoles have been successfully synthesized in good to excellent yields, starting from readily accessible thiosemicarbazides, bis-diarylthiourea, 1,3-disubtituted thiourea, and thioamides.

Synthesis and structure elucidation of some new thioether derivatives of 1,2,4-triazoline-3-thiones and their antimicrobial activities
5-(4-Pyridinyl)-4-substituted-2,4-dihydro-3H-1,2,4-triazole-3-thiones and 5-(4-pyridinyl)-4-substituted-3-(benzoylmethyl)thio 4H-1,2,4-triazoles were synthesized. The structures of original nine compounds were confirmed by IR, H-1 NMR, mass spectral methods and elemental analysis. The antibacterial, antifungal and antimycobacterial activities, together with those of known intermediate 1,4-disubstituted thiosemicarbazides, were reported. (C) 2001 Elsevier Science S.A.

The systematic exploration of a series of triazole-based agonists of the cation channel insect odorant receptor is reported. The structure-activity relationships of independent sections of the molecules are examined. Very small changes to the compound structure were found to exert a large impact on compound activity. Optimal substitutions were combined using a 'mix-and-match' strategy to produce best-in-class compounds that are capable of potently agonizing odorant receptor activity and may form the basis for the identification of a new mode of insect behavior modification.
