Abstract

In the present study, a series of 2-(4´-Substitutedanilinosydnon-3´-yl)-1, 3, 4-thiadiazino (6, 5-b) indoles 7a-j have been synthesized. All the synthesized compounds have been characterized by elemental and spectral (I R, 1H- NMR and Mass) spectrometric analysis. Furthermore, above mentioned compounds were evaluated for their antibacterial and antifungal activities against selected panel of pathogenic strains. Ampicillin trihydrate, ofloxacin and fluconazole, griseofulvin were used as standard drugs for antibacterial and anifungal activity respectively. Compound 7j was found the most potent one with lesser toxicity in the prepared indole derivatives.

Abstract

3-Aryl-5H,13aH-quinolino(3,2-f)(1,2,4)triazolo(4,3-b)(1,2-diaza-4-sulpho)azepines [2a-i] have been prepared by the cyclisation of 5-aryl-4-amino-3-mercapto-1,2,4-triazole by reaction with 2-chloro-3-formylquinoline in catalytic presence of p-toluene sulphonic acid. All the synthesized compounds have been characterized by elemental and spectral (IR, 1H- NMR and Mass) analysis. Furthermore, all compounds were evaluated for their antibacterial and antifungal activities against selected panel of pathogenic strains. Ampicillin trihydrate and fluconazole were used as standard drugs for antibacterial and antifungal activity, respectively. 3-(2-Chloro)phenyl-5H,13aH-quinolino(3,2-f)(1,2,4)triazolo(4,3-b)(1,2-diaza-4-sulpho)azepine [2h] was found, one of the most potent with lesser toxicity among the all prepared thiazepine derivatives.
