生物活性:
KG5 is an orally active dual PDGFRβ and B-Raf allosteric inhibitor. KG5 also inhibits Flt3, KIT and c-Raf. KG5 has anticancer, antiangiogenic activities.

体内研究:
KG5 (Compound 6; 100 mg/kg; oral administration; daily; for 26 days) treatment prevents tumor growth in an orthotopic renal cell carcinoma model.KG5 (Compound 6; 50 mg/kg; i.p.; twice daily) treatment completely blocks angiogenesis relative to vehicle control in mice (injected with Matrigel containing bFGF). Pharmacokinetic analysis of the dose and formulation of KG5 used indicated a Cmax of 3.6 μg/mL, T1/2 of 11.5 h, and an area under the concentration time curve (AUC0-12h) of 14.7 μg?h/mL.KG5 (Compound 6; 1 μM) disrupts a late step in angiogenesis during zebrafish embryogenesis.Animal Model:Male Nu/Nu mice injected with SN12C-RFP cells
Dosage:100 mg/kg
Administration:Oral administration; daily; for 26 days
Result:Prevented tumor growth in an orthotopic renal cell carcinoma model.

体外研究:
KG5 (Compound 6) inhibits vascular smooth muscle cells (VSMCs) and endothelial cells viability with EC50 values of 0.59 μM and 0.54 μM, respectively.Compound 6 selectively blocks S338 phosphorylation, yet does not influence S259.KG5 (Compound 6) inhibits only PDGFRα and β with Kds of 300 and 520 nM, respectively, and Flt3 and KIT at 52 and 170 nM, respectively. KG5 (Compound 6; 5 μM) inhibits phosphorylation of MEK and ERK in endothelial cells stimulated with bFGF or VEGF.
