BRD0705 is a potent, paralog selective and orally active GSK3α inhibitor (IC50: 66 nM; Kd: 4.8 μM). BRD0705 displays increased selectivity for GSK3α (8-fold) versus GSK3β (IC50: 515 nM).

BRD0705 displays excellent selectivity in a penal of 311 kinases, the CDK family of kinases (CDK2, 3 and 5) are next most potently inhibits at values of 6.87 μM, 9.74 μM and 9.20 μM (87-fold, 123-fold and 116-fold selectivity relative to GSK3α). BRD0705 (10-40 μM; 2-24 hours; U937 cells) treatment impairs GSK3α Tyr279 phosphorylation in a time-and concentration-dependent manner without affecting GSK3β Tyr216 phosphorylation. BRD0705 impairs AML colony formation in all six tested cell lines, MOLM13, TF-1, U937, MV4-11, HL-60, and NB4, in a concentration-dependent manner, as opposed to BRD3731 which impairs colony formation in TF-1 while increasing colony-forming ability in the MV4-11 cell line.

In AML mouse models, BRD0705 (30 mg/kg; oral gavage; twice daily; NSG mice) treatment impairs leukemia initiation and prolongs survival.
