Conbercept
Based on 1 Customer Validation
Conbercept (KH902) is a recombinant fusion protein composed of VEGFR-1 (second domain) and VEGFR-2 (third and fourth domains) regions fused to human IgG1 Fc. Conbercept is a VEGF inhibitor (IC50 = 8.8 pM) and is a soluble receptor decoy that blocks all isoforms of VEGF-A (Kd = 0.5 pM), VEGF-B (Kd = 8 pM), VEGF-C, and PlGF (Kd = 5 pM). Conbercept has anti-inflammatory effects, can lower the levels of VEGF, TNF-α and IL-6, and reduce the infiltration of inflammatory cells. Conbercept decreases tumor growth in several oncology studies. Conbercept can be used for various eye diseases such as polypoidal choroidal vasculopathy (PCV), diabetic macular edema (DME) and pathologic myopia choroidal neovascularization (pmCNV).

Conbercept (0-586.9 pM, 4 d) shows an inhibition effect on VEGF-induced HUVEC proliferation with an EC50 value of 28 pM[3][5].
Conbercept inhibits VEGF-induced HUVEC migration and tube formation and suppressed the high glucose-induced migration and sprouting of human retinal endothelial cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Conbercept (10-50 mg/kg, i,v., single dose) significantly inhibits xylene-induced ear edema in mice[1].
Conbercept (0.64 mg, 40 μL, intravitreally injection, 4 times a week or 2 times every 2 weeks, for 2 weeks) has an inhibitory effect against VEGF over the course of 81 days in rabbit[3].
Conbercept (0.5 mg, intravitreally injection, single dose) is effective to prevent the formation of experimental choroidal neovascularization (CNV) and also to treat preexisted CNV without evidence of toxicity in monkey model[3][5].
Conbercept inhibits tumor growth in human hepatocellular carcinoma (HepG2), breast cancer (MCF-7), gastric carcinoma (A549), and colorectal cancer (LoVo) tumor xenograft models[3].
