A five-step synthesis of an array of N-aryl-3-alkylidenepyrrolinones, which are potential Niemann-Pick type C (NPC) disease therapeutics, is described. The synthetic route allows for the production of analogues, including photoaffinity and biotinylated derivatives. Compound 1a increased esterification by acyl-coenzyme A:cholesteryl acyltransferase in NPC1 mutant cells. It also decreased LDL uptake and increased cholesterol efflux in both NPC1-deficient and normal cells.
Discovery of Small-Molecule Autophagy Inhibitors by Disrupting the Protein–Protein Interactions Involving Autophagy-Related 5
One possible strategy for modulating autophagy is to disrupt the critical protein–proteininteractions (PPIs) formed during this process. Our attention is on the autophagy-related 12 (ATG12)–autophagy-related 5 (ATG5)–autophagy-related 16-like 1 (ATG16L1) heterotrimer complex, which is responsible for ATG8 translocation from ATG3 to phosphatidylethanolamine. In this work, we discovered a compound with
