Compstatin 坎普他汀

产品介绍

Compstatin 是一个 13 残基环肽，是补体系统 C3 的有效抑制剂，具有物种特异性。Compstatin 结合到狒狒的 C3，并对狒狒血液中的蛋白水解裂解具有抗性（类似人类）。Compstatin 只抑制灵长类补体系统的激活。Compstatin 对补体经典途径和旁路途径的 IC₅₀ 值分别为63 μM 和 12 μM。

生物活性

Compstatin, a 13-residue cyclic peptide, is a potent inhibitor of the complement system C3 with species specificity. Compstatin binds to baboon C3 and is resistant to proteolytic cleavage in baboon blood (similar to humans). Compstatin inhibits only the activation of primates’ complement system. Compstatin exhibits IC₅₀ values of 63 μM and 12 μM for classical and alterative complement pathway, respectively^[4].

体外研究

Compstatin exhibits an in vitro half-life in human blood of about2 hr.
In solution, compstatin forms a β-turn at residues Gln-5–Gly-8 with the disulfide bridge Cys-2–Cys12, residues Ile-1–Val-4, and Thr-13, forming a hydrophobic cluster.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

Compstatin (21 mg/kg) produces complete inhibition when given as a combination of bolus injection and infusion. Compstatin completely inhibits in vivo heparin/protamine-induced complement activation without adverse effects on heart rate or systemic arterial, central venous, and pulmonary arterial pressures.
Compstatin is stable in baboon plasma for more than 24 h.
Pig xenografts survival is significantly longer in the Compstatin perfused group than in the control group.

Animal Model:	Juvenile baboons (P. Anubis) weighing 10.5-28.8 kg.
Dosage:	50, 25 mg/kg 60 min after heparin and 2 min before protamine.
Administration:	A bolus injection.
Result:	Completely inhibited complement activation induced by heparin–protamine complexes.
