生物活性

製品説明	PRN1371 is an irreversible covalent FGFR1-4 kinase inhibitor, with IC50s of 0.6, 1.3, 4.1, 19.3 and 8.1 nM for FGFR1, 2, 3, 4 and CSF1R, respectively.
in vitro	PRN1371 is an irreversible nanomolar inhibitor of FGFR1−4. PRN1371 presents a unique profile of high biochemical and cellular potency (FGFR1 IC50 = 0.6 nM, SNU16 IC50 = 2.6 nM), prolonged target engagement (FGFR1 occupancy 24 h = 96%), <30% hERG inhibition at 1 μM, and good predicted ADME stability with BME reactivity Kd>100 μM. PRN1371 which maintained high FGFR1 occupancy with improved solubility and exceptional oral bioavailability^[1].
in vivo	A rat iv (2 mg/kg) PK study of compound 34 showed rapid clearance (Cl = 160 ml/min/kg), yet dosing po (20 mg/kg) demonstrated high oral exposure (AUC = 4348 h·ng/mL) and a reasonable half-life (t1/2 = 3.8 h). PK studies of compound 34 in rat, dog, and cynomolgus monkey showed rapid iv clearance in all species; however there were large species differences in oral exposure and bioavailability for monkey compared to rat and dog. In rat, high exposure upon oral dosing (e.g., Cmax = 1785 ng/mL, AUC = 4348 ng·h/mL) and >100% bioavailability (F) suggested good absorption and partial saturation of clearance mechanisms at the 20 mg/kg dose. Unique to the rat, there is a large difference in half-life between the iv (t1/2 = 0.8 h) and po (t1/2 = 3.8 h) routes of administration, also indicative of possible saturation of a clearance mechanism upon oral dosing. In the dogs, the same methylcellulose suspension formulation used for the rat gave low oral absorption and bioavailability (F < 15%). In SNU16 gastric cancer xenograft mouse model, Compound 34 induced a dose-dependent reduction in tumor volume and up to 68% tumor growth inhibition at the highest dose of 10 mg/kg b.i.d. following 27 days of treatment. All doses were well tolerated with no significant body weight loss^[1].

	実験の流れ	Human umbilical vein endothelial cells (HUVECs) were incubated in media supplemented with 10% FBS and seeded at 30 000 cells per well in a 96-well plate overnight. HUVECs were then transferred into serum free media 1 h before compound treatment. A compound concentration series was added to cells and incubated for 1 h at 37 °C. Cells were then stimulated with either 50 ng/mL of FGF2 or 50 ng/mL of VEGF for 10 min. Ice cold PBS was added to stop the reaction, and cells were washed three times to remove media. ERK phosphorylation is determined.
