Defining the targets of antiparasitic compounds

Abstract

The treatment of major human parasitic infections is dependent on drugs that are plagued by issues of drug resistance. New chemotherapeutics with novel mechanisms of action (MOA) are desperately needed to combat multi-drug-resistant parasites. Although widespread screening strategies are identifying potential new hits for development against most major human parasitic diseases, in many cases such efforts are hindered by limited MOA data. Although MOA data are not essential for drug development, they can facilitate compound triage and provide a mechanism to combat drug resistance. Here we describe and discuss methods currently used to identify the targets of antiparasitic compounds, which could circumvent this bottleneck and facilitate the development of new antiparasitic drugs.
