青蒿素抗疟疾作用机制研究
摘要
疟疾是一种由疟原虫引起的寄生虫病，主要通过蚊虫叮咬传播，对全球公共卫生构成严重威胁。尽管近年来在疟疾防控方面取得了一定进展，但耐药性问题日益突出，传统抗疟药物如奎宁等逐渐失效，迫切需要开发新的抗疟药物。青蒿素作为一种从黄花蒿中提取的化合物，自上世纪70年代被发现以来，因其卓越的抗疟效果，在全球范围内被广泛研究和应用。然而，青蒿素的抗疟机制尚未完全明确，这限制了其进一步优化应用和耐药机制的应对。因此，本文综述了青蒿素抗疟疾作用机制的研究进展。青蒿素通过抗氧化机制保护红细胞，清除自由基，减少氧化应激，调节疟疾炎症反应，抑制炎性细胞因子的过度释放，促进抗氧化酶的表达，平衡氧化还原状态。同时，青蒿素还能干扰疟原虫mRNA的转录和蛋白质翻译过程，抑制疟原虫蛋白质的合成。此外，青蒿素与宿主免疫系统相互作用，激活免疫细胞，调节炎症反应，增强宿主对疟疾的抵抗力。这些机制相互协同，共同构成了青蒿素抗疟的复杂网络。本文旨在为青蒿素抗疟机制的研究提供理论依据和实践指导，为新药研发和耐药机制的应对提供参考。

Abstract
Malaria is a parasitic disease caused by Plasmodium parasites that is primarily transmitted through mosquito bites and poses a serious threat to global public health. Although some progress has been made in malaria control in recent years, the problem of drug resistance has become increasingly prominent, and traditional antimalarial drugs such as quinine have gradually failed, and there is an urgent need to develop new antimalarial drugs. As a compound derived from A. annua, artemisinin has been widely studied and used worldwide since its discovery in the 1970s due to its superior antimalarial effects. However, the antimalarial mechanism of artemisinin is not fully defined, which limits its further optimized application and coping with resistance mechanisms. Therefore, this review summarizes the mechanisms of artemisinin. Artemisinin protects erythrocytes through antioxidant mechanisms, scavenge free radicals, reduces oxidative stress, regulates malaria inflammatory response, suppresses excessive release of inflammatory cytokines, promotes the ex pression of antioxidant enzymes, and balances the redox state. Meanwhile, artemisinin can also interfere with the transc ription of Plasmodium mRNA and the protein translation process, and inhibit the synthesis of Plasmodium proteins. Moreover, artemisinin interacts with the host immune system to activate immune cells, regulate the inflammatory response, and enhance the host resistance to malaria. These mechanisms cooperate with each other and together constitute a complex network of artemisinin antimalarial resistance. This paper aims to provide theoretical basis and practical guidance for the research on the antimalarial mechanism of artemisinin, and to provide a reference for the response of new drug development and drug resistance mechanisms.
