青蒿素是一种从菊科蒿属植物黄花蒿(Artemisia annua)中分离出来的倍半萜类天然产物,青蒿琥酯(artesunate)是其衍生物之一,具有经济、速效、低毒、不易产生耐受等特点。目前临床主要用于脑型疟疾及各种重症疟疾的抢救,对疟原虫红内期有强大且快速杀灭的作用,能够迅速控制临床发作及症状。除此之外,青蒿琥酯还具有抗肿瘤、抗病毒、抗肝纤维化、抗炎、抗菌、保护肝细胞、免疫调节等药理作用,抑制细胞增殖、诱导细胞凋亡及下调血症水平。以青蒿素类化合物为基础的联合疗法(ACTs)是多国治疗疟疾的一线方法,主要包括蒿甲醚-本芴醇、青蒿琥酯-阿莫地喹和青蒿甲醚-苯甲酰胺等。近年来国内外学者对青蒿琥酯进行了研究,发现相对于单一疗法而言,青蒿琥酯联合疗法在增强药理作用、缩短用药时长和减少不良反应等方面更具有优越性。该文通过Web of Science核心合集(Web of Science Core Collection)系统检索并通过CiteSpace(6.2.1)软件对其进行整合,综述了近5年来青蒿琥酯联合其他药物在抗疟、抗肿瘤、抗菌和抗病毒等方面的作用机制并对其进行阐述,旨在为进一步合理开发利用青蒿琥酯及新药研发提供一定的理论依据。
