adducts. The effect of these compounds on the proliferation of breast cancer cell lines (MCF-7) and the corresponding Doxorubicin (Dox) resistant cell lines (MCF-7/ADR) was studied. Aminoalcohols 1a–d were obtained from the Michael addition reaction of 3,4-dimethoxyphenylethylamine and BH adducts. For the preparation of unsaturated amines 2a–d, BH adducts were converted into allylic bromides by treatment
从Baylis-Hillman(BH)加合物制备了一系列3,4-二甲氧基苯基乙胺衍生物。研究了这些化合物对乳腺癌细胞系(MCF-7)和相应的阿霉素(Dox)耐药细胞系(MCF-7 / ADR)增殖的影响。氨基醇1a – d是从3,4-二甲氧基苯基乙胺与BH加合物的迈克尔加成反应获得的。为了制备不饱和胺2a – d,通过在酸性溶液中用HBr处理将BH加合物转化为烯丙基溴化物。可以通过选择提供相应胺2a - d的溶剂来控制N-亲核试剂的引入。通过胺2a - d的氢化反应制备了第三类胺(3a - c)。在生物学评价方面,一些合成的化合物对细胞生长表现出中等的抑制作用。此外,在MCF-7 / ADR细胞系中,与化合物2b并用时,Dox的抗增殖作用从5%变为88%。
