Background: SMYD2 is a methyltransferase whose role in cancer is poorly understood and is lacking cell-active chemical tools.Results: We describe LLY-507, a small molecule inhibitor of SMYD2.Conclusion: LLY-507 is potent, selective, cell-active, and binds SMYD2 in a high resolution co-crystal.Significance: LLY-507 is a first-in-class cell-potent chemical probe that will be valuable in dissecting SMYD2 biology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
