dc.description.abstractA new library of phenothiazine and 1,3,4-thiadiazole hybrid derivatives (5a-u) was designed based on the molecular hybridization approach and the molecules were synthesized in excellent yields using a facile single-step chloro-amine coupling reaction between 2-chloro-1-(10H-phenothiazin-10-yl)ethanones and 2-amino-5-subsituted-1,3,4-thiadiazoles. The compounds were evaluated for their in vitro inhibition activity against Mycobacterium tuberculosis H37Rv (MTB). Compounds 5g and 5n were emerged as the most active compounds of the series with MIC of 0.8 ?g/mL (?1.9 ?M). Also, compounds 5a, 5b, 5c, 5e, 5l and 5m (MIC = 1.6 ?g/mL), and compounds 5j, 5k and 5o (MIC = 3.125 ?g/mL) showed significant inhibition activity. The structure-activity relationship demonstrated that an alkyl (methyl/npropyl) or substituted (4-methyl/4-Cl/4-F) phenyl groups on the 1,3,4-thiadiazole ring enhance the inhibition activity of the compounds. The cytotoxicity study revealed that none of the active molecules are toxic to a normal Vero cell line thus proving the lack of general cellular toxicity. Further, the active molecules were subjected to molecular docking studies with target enzymes InhA and CYP121. 2015 Elsevier Masson SAS. All rights reserved.en_US
