Primary Targetgp130
General description
A cell-permeable, orally active, quinoxalinhydrazide derivative that acts an inhibitor of gp130. Binds to gp130 and induces its phosphorylation at Ser782 in ovarian cancer cells (OVCAR-8 and CaoV-3) in a time and dose-dependent manner. Shown to be cytotoxic in a number of ovarian cancer cell lines (IC50 = 720, 490, 950, 440, 530, 88-0, and 430 nM in OVCAR-8, OVCAR-5, OVCAR-3, Caov-3, SKOV-3, HEY, and NCI/ADR-RES cells, respectively). Suppresses constitutive phosphorylation of and nuclear translocation of Stat3. Also blocks LIF and IL-6-induced Akt activation and phosphorylation of Stat3 (Y705) and Stat1 (Y701), without affecting their activation by IFN-γ. Reduces the level downstream effectors of gp130/Stat3 (survivin, MMP-7, Bcl-2, Bcl-xl, and cyclin D1) in ovarian cancer cells. Suppresses the growth of OVCAR-8 tumor xenografts in nude mice without affecting normal tissue (10 mg/kg, i.p. for 58 days).
