Abstract: Chaetocin (1), a structurally complex epidithiodiketopiperazine (ETP) alkaloid produced by Chaetomium minutum, is a potent inhibitor of protein lysine methyltransferase G9a, which plays important roles in many biological processes. Here we present our synthetic investigations to identify a simple prototype G9a inhibitor structure based on structure-activity relationship (SAR) studies on chaetocin derivatives. The simple derivative PS-ETP-1 (14) was found to be a potent G9a inhibitor with greatly reduced cytotoxicity.
