GSK1904529A is an orally active, potent and selective insulin-like growth factor-1 receptor and insulin receptor inhibitor (IGF-1R/IR IC50 = 27/25 nM; IC50 ≥3.2 μM/35 other kinases) that blocks cellular receptor autophosphorylation and downstream signaling. GSK1904529A inhibits IGF-1R-dependent proliferation in cancer cultures (IC50 in nM = 81-165/multiple myeloma, 35-62/Ewing′s sarcoma, 43/Askin’s tumor SK-N-MC, 104-124/colon cancer, 137-189/breast cancer) and suppresses the growth of human tumor xenografts in mice in vivo (30 mg/kg via qd. or bid. po.; HT29, BxPC3, COLO 205, NIH-3T3-LISN).
Orally active, potent and selective insulin-like growth factor-1 receptor (IGF-1R) & insulin receptor (InsR, IR) inhibitor in vitro and in vivo.
