Abstract

Substituted 2-(2-(4-aryloxybenzylidene)hydrazinyl)benzothiazole/benzoxazoles series were designed through molecular hybridization and synthesized in condensation reaction of hydrazinylbenzothiazole/benzoxazole with substituted aryloxy benzaldehydes. All the synthesized compounds were assigned structure based on spectral data and were evaluated for antimycobacterial activity. Among both benzothiazole and benzoxazole derivatives, the compounds 8f and 9e were found to show most potent antitubercular activity with MIC value of 0.89 and 0.92 μM which are on a par with those of standard antitubercular drugs. In order to know the binding interactions of all the compounds were docked within the mycobacterial pantothenate synthetase, which showed interactions with Asp88, Arg200, Ser196, Asn199, Met 195 and Lys 160 of pantothenate synthetase.
