Description

GSK-1904529A, also known as GSK 4529, is an IGF-1R Inhibitor, is is a promising candidate for therapeutic use in IGF-IR–dependent tumors. GSK1904529A selectively inhibits IGF-IR and IR with IC50s of 27 and 25 nmol/L, respectively. GSK1904529A blocks receptor autophosphorylation and downstream signaling, leading to cell cycle arrest. It inhibits the proliferation of cell lines derived from solid and hematologic malignancies, with multiple myeloma and Ewing's sarcoma cell lines being most sensitive. Oral administration of GSK1904529A decreases the growth of human tumor xenografts in mice, consistent with a reduction of IGF-IR phosphorylation in tumors. Despite the potent inhibitory activity of GSK1904529A on IR in vitro and in vivo , minimal effects on blood glucose levels are observed in animals at doses that show significant antitumor activity.

How to use

In Vitro:

GSK1904529A displays high affinities for IGF-1R and IR, with Kis of 1.6 and 1.3 nM, respectively. GSK1904529A (72 h) inhibits tumor cells proliferation with IC50s ranges from 35 nM to >30 μM, and Ewing's sarcoma and multiple myeloma cell lines are greatest sensitive. GSK1904529A (0.03-3 μM; 24 and 48 h) arrests cells at the G1 phase of the cell cycle. GSK1904529A (2 h) inhibits phosphorylation of IGF-IR and IR with IC50s of 22 and 19 nM in NIH-3T3/LISN and NIH-3T3-hIR cells, respectively. GSK1904529A (0.01-3 μM; 4 h) blocks the major downstream signal transduction pathways mediated by IGF-IR and IR in NIH-3T3/LISN and NIH-3T3-hIR cells.

In Vivo:

GSK1904529A (30 mg/kg; p.o. once or twice daily for 21 d) has antitumor activity in mice. GSK1904529A (1-30 mg/kg; a single p.o.) decreases IGF-I-induced IGF-IR phosphorylation in a dose-dependent manner in mice. GSK1904529A (30 mg/kg; p.o. once or twice daily for 21 d) has no significant alterations in the blood glucose levels in mice.
