The chemotherapeutic control of helminth parasites is compromised by the limited number of classes of anthelmintic drugs. Discovery of novel anthelmintics is impeded by the lack of novel screening technologies that overcome the difficulties inherent in screens based on whole organism toxicity. The development and implementation of mechanism-based screens for new anthelmintics offers great promise for the revitalization of antiparasitic drug discovery. However, mechanism-based screens must be based on a thorough understanding of the proteins or processes that offer the best chance for selective chemotherapeutic intervention. Basic research on the characterization of nematode FMRFamide-related peptides (FaRPs) has revealed that these peptides are ubiquitously distributed in helminths. Chemical identification of a number of nematode FaRPs has been achieved, and these peptides have potent and profound effects on the nematode neuromuscular system. Physiological processes mediated by nematode FaRPs (and other helminth neuropeptides) offer potential targets for the discovery of novel anthelmintics.
