GSK778 hydrochloride hydrochloride is a potent and selective BD1 bromodomain inhibitor of the BET proteins, with IC50s of 75 nM (BRD2 BD1), 41 nM (BRD3 BD1), 41 nM (BRD4 BD1), and 143 nM (BRDT BD1), respectively. GSK778 hydrochloride hydrochloride phenocopies the effects of pan-BET inhibitors in cancer models[1].

GSK778 hydrochloride inhibits BRD BD2 with the IC50s of 3950 nM (BRD2 BD2), 1210 nM (BRD3 BD2), 5843 nM (BRD4 BD2), and 17451 nM (BRDT BD2), respectively[1]. GSK778 hydrochloride (0.01-10 μM; 72 hours) inhibits the proliferative activity of human primary CD4+ T cells and the production of effector cytokines including IFNγ, IL-17A and IL-22[1]. GSK778 hydrochloride (0.001-10 μM; 5 days) has a more pronounced effect on the growth and viability of MDA-453, MOLM-13, K562, MV4-11, THP-1, and MDA-MB-231 cells[1]. GSK778 hydrochloride (1000 nM; 72 hours) inhibits proliferation, induces a cell cycle arrest and apoptosis in MV4-11, MOLM13, MDA-MB-231 and MB453 cells[1]. GSK778 hydrochloride (1000 nM; 12 days) reduces the clonogenic capacity of primary human AML cells[1].

GSK778 hydrochloride (15?mg/kg/BID; i.p. for 30 days) offers a superior survival advantage to iBET-BD2 in the aggressive MLL-AF9 AML model[1]. GSK778 hydrochloride (15?mg/kg/BID; s.c. for 14 days) reduces the production of anti-keyhole limpet hemocyanin (KLH) IgM and is well tolerated[1]. GSK778 hydrochloride exhibits Cmax (85 ng/mL), Tmax (1.48 h) and AUC∞ (132 ng.h/mL) following oral administration (10?mg/kg) in mice[1].
