The discovery and optimization of a series of small molecule EZH2 inhibitors is described. Starting from dimethylpyridone HTS hit (2), a series of indole-based EZH2 inhibitors were identified. Biochemical potency and microsomal stability were optimized during these studies and afforded compound 22. This compound demonstrates nanomolar levels of biochemical potency (IC50 = 0.002 mu M), cellular potency (EC50 = 0.080 mu M), and afforded tumor regression when dosed (200 mpk SC BID) in an EZH2 dependent tumor xenograft model.
