Opis

General description

A pyrazolo[1,5-a]pyridine derivative that acts as an potent and reversible EphB3 receptor tyrosine kinase inhibitor with an IC₅₀ of 79 nM with good mouse liver microsomal stability and aqueous solubility. Shown to suppress EphB3-induced autophosphorylation of EphB3 receptor at 10 µM in cells. When profiled against a panel of 288 kinases at 5 µM, found to also inhibit most of the Eph (Erythropoietin-producing hepatocellular carcinoma) receptor kinases including EphA1, EphA2, EphA3, EphA4, EphA5, EphA8, EphB1, EphB2, EphB3, EphB4 and other tyrosine kinases, but not EphA6 and EphA7, and is non-inhibitory towards non-RTK kinases screened except for p38α, p38β, and Qik.

Biochem/physiol Actions
