The major concern for anticancer chemotherapeutic agents is the host toxicity. The development of anticancer prodrugs targeting the unique biochemical alterations in cancer cells is an attractive approach to achieve therapeutic activity and selectivity. We designed and synthesized a new type of nitrogen mustard prodrug that can be activated by high level of reactive oxygen species (ROS) found in cancer
抗癌化学治疗剂的主要问题是宿主毒性。开发针对癌细胞中独特生化变化的抗癌前药是实现治疗活性和选择性的有吸引力的方法。我们设计并合成了一种新型氮芥前药,可以被癌细胞中发现的高水平活性氧 (ROS) 激活以释放活性化疗药物。通过NMR分析确定活化机制。这些前药对 ROS 的活性和选择性是通过测量 DNA 链间交联和/或 DNA 烷基化来确定的。这些化合物对各种癌细胞显示出 60-90% 的抑制作用,而正常淋巴细胞不受影响。据我们所知,
