Biochem/physiol Actions

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).

Dysregulation of the insulin-like growth factor-I receptor (IGF-IR) signaling pathway has been implicated in the development of many types of tumors, including prostate, colon, breast, pancreatic, ovarian, and sarcomas. Agents that inhibit IGF-IR activity may be useful in treatment of

As the follicle develops, the thickening of the granulosa compartment leads to progressively deficient supply of oxygen in granulosa cells (GCs) due to the growing distances from the follicular vessels. These conditions are believed to cause hypoxia in GCs during

Overexpression of multidrug-resistant efflux transporters is one of the major causes of chemotherapy failure. MRP1, a 190 kDa efflux transporter, confers resistance to a wide of range of chemotherapeutic drugs. Here we study the cellular effects of GSK1904529A in reversing MRP1-mediated
