Synthesis, activity and metabolic stability of non-ribose containing inhibitors of histone methyltransferase DOT1L†
Abstract
Histone methyltransferase DOT1L is a drug target for MLL leukemia. We report an efficient synthesis of a cyclopentane-containing compound that potently and selectively inhibits DOT1L (Ki = 1.1 nM) as well as H3K79 methylation (IC50 ∼ 200 nM). Importantly, this compound exhibits a high stability in plasma and liver microsomes, suggesting it is a better drug candidate.
