Synthesis of 2-methoxybenzoylhydrazone and evaluation of their antileishmanial activity

Abstract

Compounds 1-25 showed varying degree of antileishmanial activities with IC50 values ranging between 1.95 and 88.56 μM. Compounds 2, 10, and 11 (IC50=3.29±0.07 μM, 1.95±0.04 μM, and 2.49±0.03 μM, respectively) were found to be more active than standard pentamidine (IC50=5.09±0.04 μM). Compounds 7 (IC50=7.64±0.1 μM), 8 (IC50=13.17±0.46 μM), 18 (IC50=13.15±0.02 μM), and 24 (IC50=15.65±0.41 μM) exhibited good activities. Compounds 1, 3, 4, 5, 9, 12, 15, 18, and 19 were found to be moderately active. Compounds 13, 14, 16, 17, 20-25 showed weak activities with IC50 values ranging between 57 and 88 μM.
