IDENTIFICATION OF COMPOUNDS WHICH INHIBIT ATG8-ATG3 PROTEIN-PROTEIN INTERACTION AND THEIR USE AS ANTIPARASITICAL AGENTS
-
Paragraph 0093, (2015/11/16)
The present invention provides compounds or a pharmaceutically acceptable salts, solvates, stereoisomers, or prodrugs thereof which can block the Atg8-Atg3 protein-protein interaction, which is associated with autophagy in apicomplexan organisms. Pharmaceutical compositions comprising these compounds and their use for the suppression and treatment of various parasitical diseases are also provided.

Atg8 is a ubiquitin-like autophagy protein in eukaryotes that is covalently attached (lipidated) to the elongating autophagosomal membrane. Autophagy is increasingly appreciated as a target in diverse diseases from cancer to eukaryotic parasitic infections. Some of the autophagy machinery is conserved in the malaria parasite, Plasmodium. Although Atg8's function in the parasite is not well understood, it is essential for Plasmodium growth and survival and partially localizes to the apicoplast, an indispensable organelle in apicomplexans. Here, we describe the identification of inhibitors from the Malaria Medicine Venture Malaria Box against the interaction of PfAtg8 with its E2-conjugating enzyme, PfAtg3, by surface plasmon resonance. Inhibition of this protein-protein interaction prevents PfAtg8 lipidation with phosphatidylethanolamine. These small molecule inhibitors share a common scaffold and have activity against both blood and liver stages of infection by Plasmodium falciparum. We have derivatized this scaffold into a functional platform for further optimization.
