ABSTRACT:
The re-emergence of tuberculosis (TB) and the rise of drug-resistant strains of Mycobacterium tuberculosis, emphasizes the need for new antiTB drugs. This prompted us to synthesize a novel series of substituted benzothiazoles inhibiting DHFR, a promising target for mycobacterial infections. The structure and purity of all the compounds were confirmed by TLC, FTIR, 1H NMR and Mass spectral data. Molecular docking studies were also performed against Dihydrofolate reductase (DHFR) using GLIDE. The potency to inhibit DHFR was determined by enzyme inhibition studies using DHFR assay kit and also evaluated for their possible in vitro antitubercular activities. When screened for dhfr inhibitory activity, some compounds were found to active, moderate comparing with standard methotrexate . All the newly synthesized compounds were screened for antitubercular activity against Mycobacterium tuberculosis H37Rv strain by invitro MABA assay and MIC method .Compounds BTZ4, BTZ5, BTZ6 , BTZ10 were found to actively inhibit Mycobacterium tuberculosis at a concentration of 0.01 µg/ml .
