A main problem of common cancer chemotherapy is the occurrence of severe side effects caused by insufficient selectivity of the applied drugs. A possible concept to overcome this limitation is light‐driven prodrug monotherapy. The synthesis as well as photochemical and biological evaluation of new photoactivatable prodrugs is described. Best results were obtained with prodrug (S,S)‐7 a. The photochemical
常见癌症化学疗法的主要问题是由于所用药物的选择性不足而导致的严重副作用的发生。克服这一局限性的一个可能概念是光驱动前药单一疗法。描述了新的可光活化前药的合成以及光化学和生物学评估。最好的结果是前药(获得小号,小号- )7。(S,S)‐7 a中的光化学不稳定保护基团可以很容易地通过仅用2 J cm −2的功率在30分钟内用UV‐A光照射而除去。使用HTCFA测试确定体外细胞毒性可得出QIC 50的8200值和所述前药比相应的开环药物少超过两百万次的细胞毒性( - ) - (小号,小号) - 5与IC 50的约110°F值中号。大的治疗窗口使(S,S)‐7非常适合用于选择性癌症治疗。
