Some marketed antibiotics can cause mitochondria dysfunction via inhibition of the mitochondrial translation process. There is great interest in exploiting such effects within a cancer setting. To enhance accumulation of antibiotics within the mitochondria of cancer cells, and therefore delivery of a greater potency payload, a mitochondrial targeting group in the form of a triphenylphosphonium (TPP) cation was appended via an alkyl chain length consisting of 7 to 11 carbons to the ribosomal antibiotics azithromycin and doxycycline. Using MDA-MB-231 cells, the effects of each subseries on mitochondrial translation, mitochondrial bioenergetics, and cell viability are described.
一些已上市的抗生素可通过抑制线粒体翻译过程导致线粒体功能障碍。人们对在癌症环境中利用这种效应非常感兴趣。为了增强抗生素在癌细胞线粒体内的积累,从而传递更大效力的有效载荷,通过由7至11个碳原子组成的烷基链,将三苯基鏻(TPP)阳离子形式的线粒体靶向基团连接到核糖体抗生素阿奇霉素和强力霉素上。利用MDA-MB-231细胞,描述了每个子系列对线粒体翻译、线粒体生物能量学和细胞活力的影响。
