生物活性:
GSK1904529A is a potent, selective, orally active, and ATP-competitive inhibitor of insulin-like growth factor-1 receptor (IGF-1R) and insulin receptor (IR), with IC50s of 27 and 25 nM, respectively. GSK1904529A shows poor activity (IC50>1 μM) in 45 other serine/threonine and tyrosine kinases. GSK1904529A exhibits anti-tumor activity.
体内研究:
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.Animal Model:Female athymic nu/nu CD-1 mice are bring NIH-3T3/LISN tumor
Dosage:30 mg/kg
Administration:P.o. once or twice daily for 21 d
Result:Resulted in 56% (once daily) and 98% (twice daily) inhibition of tumor growth.No significant decrease in body weight on the once-daily schedule.Observed 11-13% of body weight loss, and recovered to near baseline 6 days after the cessation of treatment in twice-daily group.
体外研究:
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.
