A new series of N-(6-methoxybenzo[d]thiazol-2-yl)-2-substituted phenyl-1H-benz[d]imidazole-1-carbothioamide derivatives (5a-5h) has been synthesized and evaluated for antibacterial, antifungal and antimalarial effects. All these compounds were characterized and screened for their in vitro antimicrobial activity against selected bacterial and fungal strains. Titled compounds were also evaluated for their antimalarial activity against P. falciparum. Antimicrobial activity screening results showed that some compounds namely 5b against P. aeruginosa, 5c against S. aureus and E. coli, 5d against E. coli and P. aeruginosa and 5g against E. coli from the series have emerged as prospective antibacterial leads endowed with excellent activity (MIC 12.5-62.5 ?g/ml). While only one fungal strain C. albicans was susceptible towards synthesized compounds. On the other hand, compounds 5c and 5h exhibited noteworthy antimalarial activity with IC50 values of 0.18 & 0.11 ?g/ml as compared to standard drugs chloroquine (IC50 0.020 ?g/ml) and quinine (IC50 0.268 ?g/ml).
