GSK-126 is an inhibitor of mutant EZH2, a histone methyltransferase (HMT) that exhibits point mutations at key residues Tyr641 and Ala677; this compound does not appreciably affect WT EZH2. EZH2 is responsible for modulating expression of a variety of genes. GSK-126 competes with cofactor S-adenylmethionine (SAM) for binding to EZH2. GSK-126 displays anticancer chemotherapeutic activity by inhibiting proliferation in in vitro and in vivo models of diffuse large B-cell lymphoma.
