PU139 is a potent pan-histone acetyltransferase (HAT) inhibitor. PU139 blocks the HATs Gcn5, p300/CBP-associated factor (PCAF), CREB (cAMP response element-binding) protein (CBP) and p300 with IC 50 s of 8.39, 9.74, 2.49 and 5.35 μM, respectively
In Vitro
PU139 inhibits cell growth with GI 50 s of <60 μM (A431, A549, A2780, HepG2, SW480, U-87 MG, HCT116 and SK-N-SH and MCF7 cells). PU139 (0-100 μM; 24-72 hours) triggers caspase-independent cell death in the neuroblastoma cell line SK-N-SH. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
PU139 (25 mg/kg; i.p.) synergizes with Doxorubicin used as a prototypic chemotherapeutic drug in growth inhibition . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Male NMRI:nu/nu mice (Neuroblastoma xenografts) Dosage: 25 mg/kg Administration: Intraperitoneally (PU139) with Dxorubicin at 8 mg/kg i.v.; Administered on days 14 and 21 as a single dose of each compound or, for combination therapy; both drugs were administered successively within 1 h. Result: Optimum growth inhibition following a single PU139 therapy was moderate, but significant as compared with the untreated group and confirmed the previous findings.
