How to use

In Vitro:

PD-166866 inhibits human full-length FGFR-1 tyrosine kinase with an IC50 value of 52.4 nM and is characterized as an ATP competitive inhibitor of the FGFR-1. PD-166866 is a potent inhibitor of FGFR autophosphorylation in NIH 3T3 cells expressing endogenous FGFR-1 and in L6 cells overexpressing the human FGFR-1 tyrosine kinase. PD-166866 also inhibits bFGF-induced tyrosine phosphorylation of the 44- and 42-kDa (ERK 1/2) mitogen-activated protein kinase isoforms in L6 cells. Daily exposure of PD-166866 to L6 cells at concentrations from 1 to 100 nM results in a concentration-related inhibition of bFGF-stimulated cell growth for 8 consecutive days with an IC50 value of 24 nM.
