We have synthesized certain 6-substituted 9-methoxy-11H-indeno[1,2-c]quinolin-11-ones for antiproliferative evaluation. Results indicated that 6-alkylamine derivatives, 6-[2-(dimethylamino)ethylamino]-9-methoxy-11H-indeno[1,2-c]quinolin-11-one (5a) and its 6-[3-(dimethylamino)propylamino] derivative, 5b, were able to inhibit cells growth completely at a concentration of 100 μM while most of the 6-arylamine
我们已经合成了某些6-取代的9-甲氧基-11 H-茚并[1,2 - c ]喹啉-11-酮用于抗增殖评价。结果表明6-烷基胺衍生物,6- [2-(二甲基氨基)乙基氨基] -9-甲氧基-11 H-茚并[1,2 - c ]喹啉-11-one(5a)及其6- [3-(二甲基氨基)丙基氨基]衍生物5b能够在100μM的浓度下完全抑制细胞生长,而大多数6-芳基胺衍生物6b - 6h在相同的浓度下是无活性的。可比平均GI 50(药物摩尔浓度引起50%细胞生长抑制)为值5A(3.47μM)和图5b(3.39μM)表明,细胞毒性可能不受C-6位烷基取代基的长度影响。化合物5b的平均GI 50值为3.39μM,是活性最高的化合物,因此被选择用于进一步评估其对H460肺癌细胞周期分布的影响。结果表明,5b诱导的24h处理后,细胞周期阻滞于G2 / M期,次二倍体(sub-G0 / G1期)细胞增多。我们发现H4
