GOMES, Patrícia Ramos et al. Synthesis and evaluation of antimalarial activity of curcumin derivatives. Quím. Nova [online]. 2014, vol.37, n.3, pp.492-496. ISSN 0100-4042.

One of the main challenges in the development of new antimalarial drugs is to achieve a viable lead candidate with good pharmacokinetic properties. Curcumin has a broad range of biological activities, including antimalarial activity. Herein, we report the antimalarial activity of six curcumin derivatives (6-12) and an initial analysis of their pharmacokinetic properties. Five compounds have demonstrated potent activity against the P. falciparum in vitro (IC50 values ranging from 1.7 to 15.2 µg mL-1), with moderate or low cytotoxicity against the HeLa cell line. The substitution of the carbonyl group in 6 by a 2,4-dinitrophenylhydrazone group (to afford 11) increases the Selective Index. These preliminary results indicate curcumin derivatives as potential antimalarial compounds.

Keywords : curcumin derivatives; antimalarial chemotherapy; Plasmodium falciparum.
