5'-Methoxy-6'-[3-(1-pyrrolidinyl)propoxy]spiro[cyclobutane-1,3'-[3H]indol]-2'-amine

A-366 acts as a potent peptide-competitive inhibitor of the lysine methyltransferase G9a. 1000 fold selectivity over other methyl transferases.

A-366 is an SGC chemical probe for G9a/GLP, developed in collaboration with Abbvie. A-366 is a potent, selective inhibitor of the histone methyltransferase G9a. The IC50 values for G9a inhbition in enzymatic and cell based assays are 3.3 and approximately 3 μM, respectively. A-366 has little or no detectable activity against a panel of 21 other methyltransferases.
