even subtle changes in stereochemistry. However, no attempts have been made to improve the therapeutic window by rational drug design or by using a prodrug approach to exploit differences between tumour physiology and healthy tissue, such as acidic extracellular pH and hypoxia. Herein, we report the photochemical synthesis of highly substituted endoperoxides as key precursors for dibromohexitol derivatives
溴己糖醇代表着一类有效的DNA烷基化碳水化合物化学治疗方法,由于安全方面的考虑,在过去的几十年中,溴化己糖醇一直被人们忽略。可用的有限的结构-活性关系数据揭示了细胞毒性的显着变化,甚至立体化学上的细微变化。但是,尚未尝试通过合理的药物设计或通过使用前药方法来改善肿瘤生理学与健康组织之间的差异(例如酸性细胞外pH和低氧)来改善治疗范围。在这里,我们报告了高度取代的内过氧化物作为二溴己糖醇衍生物的关键前体的光化学合成,并研究了它们作为靶向癌细胞的微环境激活的前药的用途。
