Abstract

Novel Schiff’s bases bearing substituted 2-amino benzothiazole were synthesized by single step process through simple condensation of 2-amino benzothiazole and substituted benzaldehydes and further characterized by FTIR, 1HNMR, and Mass spectrometry data. Antimicrobial activity of compounds was performed by agar diffusion method against a panel of bacterial strains such as S. aureus, B. subtilis (Gram-positive bacteria), E. coli, P. aeruginosa (Gram-negative bacteria) and fungal strains such as C.albicans and A. niger. Compound S13 and S17 had shown potent antifungal activity against C. albicans and A. niger respectively among the novel Schiff’s base compounds when compared to standard, and S13 compound had only shown moderate antibacterial activity against S. aureus amongst all. Molecular docking study was carried out against C. albicans DHFR (Dihydrofolate Reductase) domain to confirm their activity.
