X-ray crystal structure of the orally available aminopeptidase inhibitor, Tosedostat, bound to the M17 Leucyl Aminopeptidase from P. falciparumX-ray crystal structure of the orally available aminopeptidase inhibitor, Tosedostat, bound to the M17 Leucyl Aminopeptidase from P. falciparum

FunctionPublication Abstract from PubMedNew antimalarial treatments are desperately required to face the spread of drug resistant parasites. Inhibition of metalloaminopeptidases PfA-M1 and PfA-M17 is a validated therapeutic strategy for treatment of Plasmodium falciparum malaria. Here we describe the crystal structures of PfA-M1 and PfA-M17 bound to chemotherapeutic agent Tosedostat. The inhibitor occupies the enzymes' putative product egress channels in addition to the substrate binding pockets; however, adopts different binding poses when bound to PfA-M1 and PfA-M17. These findings will be valuable for the continued development of selective inhibitors of PfA-M1 and PfA-M17. This article is protected by copyright. All rights reserved.
