生物活性
GSK1904529A是一种选择性的IGF-1R和IR抑制剂,IC50分别为27 nM和25 nM,作用于IGF-1R/InsR比作用于Akt1/2/, Aurora A/B,B-Raf, CDK2, EGFR等选择性高100倍以上。GSK1904529A 是选择性抑制剂,作用于IGF-IR和IR时IC50分别为27和25 nM。GSK1904529A是可逆的ATP竞争性抑制剂。GSK1904529A 作用于IGF-IR和IR时Ki值分别为1.3和1.6 nM。
GSK1904529A(1-30 毫克/千克;单次口服)以剂量依赖的方式降低小鼠 IGF-I 诱导的 IGF-IR 磷酸化。
实验参考
体外实验*
细胞系 NCI-H929, NIH-3T3/LISN, COLO 205, HT29, and BxPC3 cells
方法 Cell proliferation assays.
Cells were seeded in 96-well dishes, incubated overnight at 37°C, and treated with various concentrations of GSK1904529A for 72 h. For the NIH-3T3/LISN proliferation assays, cells were seeded on collagen-coated 96-well tissue culture plates (BD Biosciences) and allowed to adhere for 24 h. The tissue culture medium was replaced with serum-free medium and the cells were treated with DMSO or GSK1904529A for 2 h. IGF-I (30 ng/mL) was added and the cells were incubated at 37°C for 72 h. Cell proliferation was quantified using the CellTiter-Glo Luminescent Cell Viability Assay (Promega) following the manufacturer's recommendations. IC50 values were determined by using a four-parameter curve fit software package (XLfit4).
