Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

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.

Biological target:
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.
In vitro activity:
Cell counting assay results in Figure 1A demonstrated that treatment GSK1904529A, at 50/250 nM, significantly inhibited Saos-2 cell proliferation. The number of viable Saos-2 cells was significantly reduced following GSK1904529A (50/250 nM) treatment, at 30-, 60-, and 90-hour durations (Figure 1A). GSK1904529A displayed a concentration-dependent manner in inhibiting Saos-2 cell proliferation (Figure 1A). Treatment with GSK1904529A in Saos-2 cells also dramatically decreased MTT OD (Figure 1B) and number of colonies (Figure 1C). GSK1904529A at 250 nM was again more potent than 50 nM in inhibiting Saos-2 cell proliferation (Figure 1B and 1C). Reference: Oncotarget. 2017 Jul 25;8(30):49646-49654. https://pubmed.ncbi.nlm.nih.gov/28572530/
In vivo activity:
The data revealed that the mice treated with GSK1904529A exhibited substantially reduced tumor volumes compared with the vehicle-treated group (Fig. 4A). The suppression of tumor growth was correlated with the dose of GSK1904529A (Fig. 4A). In addition, the treatment was well tolerated, as no weight loss was observed (Fig. 4B). Further investigation revealed that treatment with GSK1904529A induced marked apoptosis in the tumor cells (Fig. 4C), which was consistent with the in vitro data. Taken together, these data suggested that GSK1904529A markedly inhibited glioma tumor growth in vivo. Reference: Mol Med Rep. 2015 Sep;12(3):3381-3385. https://pubmed.ncbi.nlm.nih.gov/26035416/
