Regular aspirin use has been convincingly shown to reduce the risk of colorectal cancer. However, long-term use of aspirin leads to gastrotoxicity. Herein, we designed and synthesized a novel class of resveratrol-based aspirin prodrugs to simultaneously release aspirin and resveratrol to attenuate the side effects caused by aspirin. Prodrug RAH exerted enhanced anticancer activities which are better
令人信服的是,定期服用阿司匹林可以降低结直肠癌的风险。但是,长期服用阿司匹林会导致胃毒性。本文中,我们设计和合成了一类新的基于白藜芦醇的阿司匹林前药,以同时释放阿司匹林和白藜芦醇以减轻由阿司匹林引起的副作用。前药RAH发挥了增强的抗癌活性,优于阿司匹林和白藜芦醇的物理混合物以及各自的抗癌活性。小鼠中RAH的代谢表明,大部分RAH在肠道内或吸收后被分解释放白藜芦醇和阿司匹林或水杨酸。机理研究表明,RAH通过下调细胞周期蛋白抑制细胞周期停滞,并通过激活癌细胞中的caspase-3诱导细胞凋亡。这些发现突显了基于白藜芦醇的阿司匹林前药的抗癌特性得到改善。RAH可能代表阿司匹林的新颖和安全替代品,以供日后日后使用。
