KW-2449 hydrochloride (Cat No.:I000066) is a multi-targeted inhibitor with a strong affinity for FMS-like tyrosine kinase 3 (Flt3) with an IC50 of 6.6 nM. It also exhibits moderate potency against fibroblast growth factor receptor 1 (FGFR1), Bcr-Abl, and Aurora A kinases. However, it has little effect on platelet-derived growth factor receptor beta (PDGFRβ), insulin-like growth factor-1 receptor (IGF-1R), and epidermal growth factor receptor (EGFR). The broad spectrum of kinase inhibition suggests potential applications of KW-2449 in targeting multiple signaling pathways implicated in various diseases, including cancer.
