AZD-4547

개요AZD 4547 is a selective inhibitor of the fibroblast growth factor receptor (FGFR) tyrosine kinase with IC50 values of 0.2, 2.5, and 1.8 nM for FGFR1, 2, and 3, respectively. It displays weaker activity against FGFR4 (IC50 = 165 nM), VEGFR2 (IC50 = 24 nM), and a panel of other tyrosine and serine/theronine kinases such as insulin-like growth factor 1 receptor (IC50 = 581 nM), cyclin-dependent kinase 2 (IC50 = >10 μM), and p38 (IC50 = >100 μM). AZD 4547 has demonstrated antiproliferative activity in tumor cell lines expressing deregulated FGFRs (IC50s = 18-281 nM). In an FGFR-driven human tumor xenograft mouse model, oral administration of AZD 4547 at concentrations up to 12.5 mg/kg/day resulted in potent dose-dependent antitumor activity.

용도AZD4547 is a bioavailable, potent, and selective inhibitor of the fibroblast growth factor receptor (FGFR) tyrosine kinases. AZD4547 is particularly effective in inhibiting FGFR1, 2, and 3 tyrosine k inases and is under clinical investigation for the treatment of FGFR-dependent tumors.
