Inhibitors of Plasmepsin II, an Anti-Malarial target

Compounds and methods for the inhibition of anti-malarial target aspartyl protease plasmepsins (e.g. Plasmepsin I, Plasmepsin II, Plasmepsin IV and HAP) are provided. The compounds are based on allophenylnorstatine substituted at positions R1-R4, such that R1 is isoquinoline, carboxyl, naphtalene, phenyl, phenol, benzene, an amino acid, and derivatives thereof; R2 and R3 are aliphatic groups; and R4 is indan, naphthalene, benzylamine, phenyl, phenol, cyclopentane, tert-butylamine, or derivatives thereof. The compounds may be used to inhibit Plasmepsin II, to kill malarial parasites, and to treat malaria in a patient. Certain of the substituted allophenylnorstatine-based compounds also exhibit inhibitory activity against Cathepsin D.
