The impact of substitutions at position 10 in the A ring of the cytotoxic benzo[a]acronycine and benzo[b]acronycine series has been explored. 10-Bromobenzo[a] and 10-bromobenzo[b]acronycine were prepared in 12% and 15% yield respectively from commercially available chemicals. Their 1,2-dihydro-1,2-dihydroxy diesters were synthesized. The different derivatives were tested against two cell lines KB-3-1
已经研究了细胞毒性苯并[ a ]阿卡洛霉素和苯并[ b ]阿卡洛霉素系列的A环上第10位取代的影响。由市售化学品分别以12%和15%的收率制备10-溴苯并[ a ]和10-溴苯并[ b ]阿卡那霉素。合成了它们的1,2-二氢-1,2-二羟基二酯。针对两种细胞系KB-3-1和L1210测试了不同的衍生物。发现它们的细胞毒性活性与其未取代的对应物在相同的范围内。这些结构-活性关系可以得出结论,即在10位上引入取代基可以保持苯并[ a ]和[ b ]的活性。]强力霉素系列产品,为进一步的药物调节开辟了道路。
