Description: GTP-14564 is a novel tyrosine kinase inhibitor that also inhibits wt-FLT3 and ITD-FLT3. GTP-14564 inhibits the growth of interleukin-3-independent Ba/F1 expressing ITD-FLT3 at 3 µ m, whereas a 30-fold higher concentration of GTP-14564 is required to inhibit the FLT3 ligand-dependent growth (wt-FLT3) of...

GTP 14564 is an inhibitor of class III receptor tyrosine kinases (IC50s = 0.3 µM for c-Fms, c-Kit, ITD-FLT3 and 1 µM for PDGFRbeta). It is without effect against a panel of non-receptor tyrosine and serine/threonine kinases. GTP 14564 blocks the proliferation of leukemia cells stimulated with FLT3 ligand by...
