Abstract:

青蒿素是中国自主研制的抗疟良药,高效、低毒,许多基于青蒿素研发的衍生物具有良好的抗疟效果,近年来已成为抗疟的一线药物,受到世界医疗卫生界的充分肯定.虽然青蒿素结构奇特,抑疟效果显著,但40年来其生物作用机制之谜一直未被彻底破解.针对青蒿素类药物的作用机制,提出了不同的假说,如血红素参与青蒿素的激活并被烷基化从而起到抑疟作用,线粒体参与青蒿素的激活和作用过程,某些特定的蛋白是青蒿素作用靶点等.除抑疟外,青蒿素类药物在杀灭其他种类寄生虫、抑制某些癌症细胞以及抗病毒、治疗类风湿等方面也有一定作用.本文将对青蒿素类药物作用机制的研究进行综述及展望,包括抗疟疾过程中的药物激活、作用靶点以及简要的青蒿素抑制肿瘤细胞作用机制,以期为今后的研究提供帮助.
