The syntheses and antiproliferative activities of novel substituted tetrahydroisoquinoline derivatives and their sulfamates are discussed. Biasing of conformational populations through substitution on the tetrahydroisoquinoline core at C1 and C3 has a profound effect on the antiproliferative activity against various cancer cell lines. The C3 methyl‐substituted sulfamate (±)‐7‐methoxy‐2‐(3‐methoxyb
讨论了新型取代的四氢异喹啉衍生物及其氨基磺酸盐的合成和抗增殖活性。通过在C1和C3上的四氢异喹啉核心上取代而对构象群体进行偏倚,对针对各种癌细胞系的抗增殖活性具有深远的影响。例如,发现C3甲基取代的氨基磺酸(±)-7-甲氧基-2-(3-甲氧基苄基)-3-甲基-6-氨磺酰氧基-1,2,3,4-四氢异喹啉(6 b)相对于相应的未甲基化化合物7-甲氧基-2-(3-甲氧基苄基)-6-氨磺酰氧基-1,2,3,4-四氢异喹啉(4 b)效力比DU-145前列腺癌细胞高约10倍(GI 50个值:220n中中号和2.1μ中号, 分别)。还发现此类化合物对耐药的MCF乳腺癌细胞系具有活性。发现C3取代系列中N苄基的取代位置和性质对活性有重大影响。尽管C1甲基化对活性几乎没有影响,但是引入C1苯基和C3- gem-二甲基取代基会大大降低抗增殖活性。这些化合物与秋水仙碱竞争性抑制微管聚合和结合微管蛋白的能力证实了
