therapeutic agents to mitochondria, which synergistically promote mitochondrial ROS production and induce mitochondrial DNAdamage, finally leading to mitochondria‐mediated apoptosis of cancer cells. Our in vitro and in vivo experiments reveal the excellent anticancer efficacy of these prodrugs, underscoring the encouraging outlook of this strategy for effective cancer therapy.
position of Pt(IV), we developed a novel and efficient approach for the synthesis of Pt(IV)–carbamato complexes and demonstrated that following reduction of the Pt(IV), the released carbamates undergo rapid decarboxylation, releasing the free amine, as in the case of the PARP-1 inhibitor 3-aminobenzamide and the amino derivative of the HDAC inhibitor SAHA. Pt(IV)–carbamato complexes are stable in cell

possibilities considering the sensitivity of PtIV centers, we used a strain‐promoted azide–alkyne cycloaddition approach to provide a platform, in which new functionalities can easily be installed on cisplatinprodrugs from a single PtIV precursor. The ability of this platform to be incorporated in nanodelivery vehicle and conjugation to fluorescent reporters were also investigated.
合理设计和构建平台技术以开发新的铂 (IV) [Pt IV ] 前药的能力,该前药具有用于安装靶向部分、递送系统、来自单一前体的荧光报告基因的功能,并且能够通过使用良好的方式释放生物活性顺铂定义的化学对于发现新的基于铂的疗法至关重要。考虑到 Pt IV中心的敏感性,可能性有限,我们使用了应变促进的叠氮化物-炔烃环加成方法来提供一个平台,在该平台中,可以轻松地将新功能安装在来自单个 Pt IV 的顺铂前药上前体。还研究了该平台被纳入纳米递送载体和与荧光报告基因缀合的能力。
