Nodulisporic acid A (1) is a structurally complex fungal metabolite that exhibits systemic efficacy against fleas via modulation of an invertebrate specific glutamate-gated ion channel. In order to identify a nodulisporamide suitable for monthly oral dosing in dogs, a library of 335 nodulisporamides was examined in an artificial flea feeding system for(More)
Medicinal chemistry efforts were initiated to identify the key constituents of the nodulisporic acid A (1) pharmacophore that are integral to its potent insecticidal activity. New semisynthetic derivatives delineated 1 into 'permissive' and 'nonpermissive' regions and led to the discovery of new nodulisporamides with significantly improved flea efficacy.
