Abstact

The malaria parasite Plasmodium falciparum employs two metallo-aminopeptidases, PfA-M1 and PfA-M17, which are essential for parasite survival. Compounds that inhibit the activity of either enzyme represent leads for the development of new antimalarial drugs. Here we report the synthesis and structure-activity relationships of a small library of phosphonic acid arginine mimetics that probe the S1 pocket of both enzymes and map the necessary interactions that would be important for a dual inhibitor.
