Synthesis and pharmacological studies of 1-(2-amino-1-(4-methoxyphenyl) ethyl) cyclohexanol analogs as potential microbial agents

A novel series of Schiff bases 4a–n was prepared from 2-hydrazinyl-N-(2-(1-hydroxycyclohexyl)-2-(4-methoxyphenyl) ethyl)acetamide. Thiazolidinone 5a–n derivatives were prepared from the reaction of Schiff base and thioglycolic acid. The structures of the synthesized compounds were assigned on the basis of elemental analysis, IR, 1H NMR, 13C NMR and Mass spectral data. All the compounds were screened against different strains of bacteria and fungi. These active compounds impelled us to study their antitubercular activity. Compounds 4b, 5a, 5b, 5d, 5e, 5f, 5k, 5l and 5n emerged as promising antimicrobials. It was also observed that the promising antimicrobials have proved to be better antituberculars. Compound 5k showed better antitubercular activity compared to Rifampicin
