网格蛋白介导型内吞作用与广谱抗病毒药

摘要

Viral disease is a serious threat for human health. Alhough plenty of antiviral agents have been used in clinical treatment, many viruses are resistant to them via virus mutation. And novel harmful viruses emerge in endlessly. So research and development of new antiviral drugs, especially the agents that are of broad-spectrum antiviral activity is particularly important. Clathrin-mediated endocytosis is the most common pathway used by viruses and pathogens for entering host cells. The inhibitors of clathrin-me-diated endocytosis may block the entry of viruses and pathogens, thus prevent viral infection. For the inhibitors do not directly act on the virus itself, it is hard to induce virus mutations which produce drug resistance. Clathrin-mediated endocytosis is the potential target of broad-spectrum antiviral agents in recent years. This review focuses on the mechanism of virus entry through clathrin-mediated endocytosis, the recent advances of clathrin-mediated endocytosis inhibitors and their potential applications in broad-spectrum antiviral therapeutics field.%病毒性疾病对人类的健康造成了巨大的威胁,虽然有很多药物用于临床治疗,但由于病毒的易变异性,对现有的抗病毒药物极易产生耐药性,而新发病毒又层出不穷,因此研发新的抗病毒药物尤其是广谱且不易产生耐药的抗病毒药物对于病毒性疾病的治疗就显得尤为重要.网格蛋白介导型内吞是许多病毒和病原体进入宿主细胞的主要途径,抑制此途径可阻断病毒进入宿主细胞,从而抑制病毒感染,由于其功能和机制与病毒自身无关,不易产生耐药,是近年来广谱抗病毒药物的潜在作用靶标.本文结合国内外最新研究报道,简要综述了病毒依赖网格蛋白介导型内吞入胞的机制,网格蛋白介导型内吞抑制剂的研究现状,及其在广谱抗病毒药物研发中的潜在应用前景.
