New Pyrrole Hydrazones Synthesized and Evaluated In Vitro as Potential Tuberculostatics
Sixteen hydrazones were synthesized as derivatives of 1H-1-pyrrolylcarbohydrazides. Five products exhibited 68-97% inhibition against Mycobacterium tuberculosis H37Rv at 6.25 μg/mL using MABA, the most active displaying IC50=7.979 μg/mL and IC90 > 100 μg/mL. Activities correlated with the hydrophobic parameters according to second order QSAR model favoring 4.4 LogP 5.2.
