Inhibitors of Plasmodium falciparum methionine aminopeptidase 1b possess antimalarial activity.

ABSTRACT: With >1 million deaths annually, mostly among children in sub-Saharan Africa, malaria poses one of the most critical challenges in medicine today. Although introduction of the artemisinin class of antimalarial drugs has offered a temporary solution to the problem of drug resistance, new antimalarial drugs are needed to ensure effective control of the disease in the future. Herein, we have investigated members of the methionine aminopeptidase family as potential antimalarial targets. The Plasmodium falciparum methionine aminopeptidase 1b (PfMetAP1b), one of four MetAP proteins encoded in the P. falciparum genome, was cloned, overexpressed, purified, and used to screen a 175,000-compound library for inhibitors. A family of structurally related inhibitors containing a 2-(2-pyridinyl)-pyrimidi
