Description: CT52923, also known as KN734, is a platelet-derived growth factor receptor (PDGFR) inhibitor. CT52923 exhibited remarkable specificity when tested against other kinases, including all members of the closely related PDGFR family. The PDGFRs and stem cell factor receptor were inhibited with an IC(50) of 100 to 200 nM, while 45- to >200-fold higher concentrations of CT52923 were required to inhibit fms-like tyrosine kinase-3 and colony-stimulating factor-1 receptor, respectively. In addition, CT52923 also demonstrated specificity for inhibition of cellular responses.
