Abstract

A new series of N-acetyl and N-formyl-pyrazoline derivatives 6 and 7-8 were synthesized by cyclocondensation reaction of [(7-chloroquinolin-4-yl)amino]Chalcones with hydrazine hydrate in acetic acid and hydrazine hydrate in formic acid respectively. These compounds were evaluated in vitro as antitumor and as antimalarial agents. Compounds 7b and 8b-e showed remarkable antitumor activity against Cancer cell lines, with the most important GI50 values ranging from 0.13 to 0.99 μM. The best antimalarial response was observed for compound 7a with an inhibition percentage of 50.8% for Plasmodium falciparum, a hemolytic capacity of 3.2% and an IC50 of 14.1 μg/mL.
