CPL304110 is a potent, orally active and selective inhibitor of fibroblast growth factor receptors FGFR (1-3), with IC₅₀ values of 0.75 nM, 0.5 nM, and 3.05 nM for FGFR (1-3), respectively^[1].

CPL304110 (0-0.6 μM) dose-dependently inhibits FGFR2 phosphorylation and downstream signaling (p-ERK)^[1].
CPL304110 (compound 56q) exhibits in SNU-16 proliferation assay with an IC₅₀ of 85.64 nM^[1].
CPL304110 (compound 56q) demonstrats a more than 45-fold, 345-fold, 395-fold and 680-fold selectivity over KDR (VEGFR2), Flt3, Aura A and PDGFRb, respectively relative to FGFR2, and no significant inhibitory effects were observed with other tyrosine kinases^[1].

CPL304110 (p.o., 40 mg/kg) exhibits a t_1/2 of 2 h and C_max of 3369 ng/mL in mice^[1].
CPL304110 (compound 56q, 2 X 20 mg/kg) significantly inhibits tumor growth in mice without significant body loss or any toxicity. On day 21 (D21, day of termination) the tumor growth inhibition (TGI) is 64% for dosing 20 mg/kg twice a day^[1].
