In the present investigation, a series of 3a, 4-dihydro-3H-indeno [1, 2-c] pyrazole-2-
carboxamide analogues were synthesized and were evaluated for antitubercular activity by
two fold serial dilution technique. All the newly synthesized compounds showed low to good
inhibitory activities against Mycobacterium tuberculosis H37Rv and multi-drug resistant M.
tuberculosis (MDR-TB). 3-(4-fluorophenyl)-N-(4-chlorophenyl)-6, 7-dimethoxy-3a, 4-dihydro-
3H-indeno [1, 2-c] pyrazole-2-carboxamide (4c) was found to be the most promising …
In the present investigation, a series of 3a,4-dihydro-3H-indeno [1,2-c] pyrazole-2-carboxamide analogues were synthesized and were evaluated for antitubercular activity by two fold serial dilution technique. All the newly synthesized compounds showed low to good inhibitory activities against Mycobacterium tuberculosis H37Rv and multi-drug resistant M. tuberculosis (MDR-TB). 3-(4-fluorophenyl)-N-(4-chlorophenyl)-6,7-dimethoxy-3a,4-dihydro-3H-indeno [1,2-c] pyrazole-2-carboxamide (4c) was found to be the most promising compound active against M. tuberculosis, H37Rv and MDR-TB with minimum inhibitory concentrations 0.83 μM and 3.32 μM respectively.
