Abstract
Developing novel antileishmanial, and cytotoxic drugs has been a significant area in modern pharmaceutical research. A series of novel triazolo[4,3-a]quinoline, triazino[4,3-a]quinoline, thiadiazepino[5,6-b]quinoline and pyrazolquinoline have been synthesized from the reaction of 2-hydrazinyltetrahydroquinoline-3-carbonitrile with formamide, formic acid, ethyl chloroacetate, carbon disulphide in an alcoholic solution of potassium hydroxide acetyl acetone and/or ethyl cyanoacetate, respectively. These compounds were evaluated for their in vitro studies against L. major leishmanial. The brine shrimp bioassay was also conducted to study their in vitro cytotoxic properties which displayed potent cytotoxic activity against Vincristine. The newly synthesized compounds were all characterized through IR, 1H-NMR, and MS.
