The development of new drugs is one strategy for malaria control. Biochemical pathways localised in the apicoplast of the parasite, such as the synthesis of isoprenic precursors, are excellent targets because they are different or absent in the human host. Isoprenoids are a large and highly diverse group of natural products with many functions and their synthesis is essential for the parasite's survival. During the last few years, the genes, enzymes, intermediates and mechanisms of this biosynthetic route have been elucidated. In this review, we comment on some aspects of the methylerythritol phosphate pathway and discuss the presence of diverse isoprenic products such as dolichol, ubiquinone, carotenoids, menaquinone and isoprenylated proteins, which are biosynthesised during the intraerythrocytic stages of Plasmodium falciparum.
新药的开发是疟疾控制的一种策略。寄生虫类质体中定位的生化途径,如异戊烯前体的合成,是很好的靶点,因为它们在人类宿主中不同或不存在。类异戊二烯是一个庞大而高度多样化的天然产物群体,具有多种功能,其合成对于寄生虫的生存至关重要。在过去的几年中,已经阐明了该生物合成途径的基因、酶、中间产物和机制。在这篇综述中,我们评论了磷酸甲基赤藓醇途径的一些方面,并讨论了在疟原虫的红细胞内阶段合成的各种异戊烯产物,如鲨烯、泛醌、类胡萝卜素、甲萘醌和异戊烯化蛋白。
