Identification of new antimalarial leads by use of virtual screening against cytochrome bc₁

Bioorg Med Chem. 2011 Nov 1;19(21):6302-8. doi: 10.1016/j.bmc.2011.09.004. Epub 2011 Sep 10.

Abstract

Cytochrome bc(1) is a validated drug target in malaria parasites. The spread of Plasmodium falciparum strains resistant to multiple antimalarials emphasizes the urgent need for new drugs. We screened in silico the ZINC and MOE databases, using ligand- and structure-based approaches, to identify new leads for development. The most active compound presented an IC(50) value against cultured P. falciparum of 2 μM and a docking pose consistent with its activity.
