for the multidrug resistance of the anticancer agent doxorubicin (DOX). The strategy may thus increase DOX toxicity against resistant cancer cells. Moreover, a novel molecular hybrid covalently joining DOX and NOP showed similar increased toxicity toward resistant cancer cells and, in addition, lower cardiotoxicity than DOX. This opens new and underexplored approaches to overcoming the main therapeutic
可以通过可见光刺激微调合适的NO光供体(NOP)中释放的一氧化氮(NO),剂量对细胞无毒,但会抑制多个外排泵。这些主要负责抗癌药阿霉素(DOX)的多药耐药性。因此,该策略可能会增加DOX对耐药癌细胞的毒性。此外,共价连接DOX和NOP的新型分子杂合体显示出对耐药癌细胞的相似增加的毒性,此外,其心脏毒性比DOX低。这为克服基于光控释放NO的这种化学治疗方法的主要治疗缺陷开辟了新的方法,但尚未被开发。
