Title:

Abstract:

Herein we disclose SAR studies of a series of dimethylamino pyrrolidines which we recently reported as novel inhibitors of the PRC2 complex through disruption of EED/H3K27me3 binding. Modification of the indole and benzyl moieties of screening hit 1 provided analogs with substantially improved binding and cellular activities. This work culminated in the identification of compound 2, our nanomolar proof-of-concept (PoC) inhibitor which provided on-target tumor growth inhibition in a mouse xenograft model. X-ray crystal structures of several inhibitors bound in the EED active-site are also discussed.
