摘要 线虫抗凝血蛋白c2(NAPc2)是从犬钩虫中分离出来的一种蛋白,它通过结合于fXa的催化活性中心以外的部位而进一步特异性抑制fVⅡa/TF复合物。在国外,rNAPc2正作为一种新型抗凝药运用于临床试验中,它抗凝效果明显,半衰期长(>50 h),副作用小。此外,它还可能在治疗D IC、肿瘤等疾病方面具有潜在应用价值。本文就NAPc2的结构与功能、作用机制和临床应用研究进展做一综述并展望其应用前景。 Nematoda anticoagulant protein c2 ( NAPc2 ) is a protein originally isolated from the canine hookworm Ancylostoma caninum. NAPe2 binds to a noncatalytic site on fX a then selectively inhibits fV Ⅱ a/TF complex. NAPe2 is proven to be a safe and potent anticoagulant in Phase Ⅰ and Phase Ⅱ clinical trials, and it has prolonged elimination half-life (longer than 50 h). In a word, NAPc2 may play a promising role in the prevention and treatment of thrombosis, disseminated intravascular coagulopathies (DIC) and tumor.
