KG5 是一种具有口服活性的双重PDGFRβ和B-Raf变构抑制剂。KG5 还抑制Flt3,KIT和c-Raf,并具有抗癌,抗血管生成活性。
生物活性 | KG5 is an orally active dualPDGFRβandB-Rafallosteric inhibitor. KG5 also inhibitsFlt3,KITandc-Raf. KG5 has anticancer, antiangiogenic activities[1]. |
IC50& Target[1] | PDGFRβ 520 nM (Kd) | PDGFRα 300 nM (Kd) | B-Raf | c-Raf | FLT3 52 nM (Kd) | KIT 170 nM (Kd) |

体外研究 (In Vitro) | KG5 (Compound 6) inhibits vascular smooth muscle cells (VSMCs) and endothelial cells viability with EC50values of 0.59 μM and 0.54 μM, respectively[1]. Compound 6 selectively blocks S338 phosphorylation, yet does not influence S259[1]. 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[1]. KG5 (Compound 6; 5 μM) inhibits phosphorylation of MEK and ERK in endothelial cells stimulated with bFGF or VEGF[1].

体内研究 (In Vivo) | KG5 (Compound 6; 100 mg/kg; oral administration; daily; for 26 days) treatment prevents tumor growth in an orthotopic renal cell carcinoma model[1]. 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 Cmaxof 3.6 μg/mL, T1/2of 11.5 h, and an area under the concentration time curve (AUC0-12h) of 14.7 μgoh/mL[1]. KG5 (Compound 6; 1 μM) disrupts a late step in angiogenesis during zebrafish embryogenesis[1].
Animal Model: | Male Nu/Nu mice injected with SN12C-RFP cells[1] | Dosage: | 100 mg/kg | Administration: | Oral administration; daily; for 26 days | Result: | Prevented tumor growth in an orthotopic renal cell carcinoma model. |
