Diastereomeric N,N'-dialkyl-1,2-bis(hydroxyphenyl)ethylenediamines (5) were synthesized and tested for their affinity for the estradiol receptor. Only the (+/-)-1,2-bis(4-hydroxyphenyl)ethylenediamines with the alkyl groups C3H7 [(+/-)-5c, Ka = 1.1 x 19(6))], C4H9 [(+/-)-5e,Ka = 3.6 x 10(6)], and C5H11 [(+/-)-5h, Ka = 2.2 x 10(6)] showed a marked affinity, which is mainly due to the (+) enantiomers
合成了非对映异构的N,N'-二烷基-1,2-双(羟苯基)乙二胺(5),并测试了它们与雌二醇受体的亲和力。仅具有烷基C3H7 [(+/-)-5c,Ka = 1.1 x 19(6))]的(+/-)-1,2-双(4-羟苯基)乙二胺,C4H9 [(+/- )-5e,Ka = 3.6 x 10(6)]和C5H11 [(+/-)-5h,Ka = 2.2 x 10(6)]显示出显着的亲和力,这主要是由于(+)对映体[例如(+)-5e,Ka = 2.1 x 10(7)]。没有观察到通过环化对咪唑烷类[例如(+/-)-trans-7a,Ka = 1.2 x 10(7)]的亲和力增强。这些化合物[例如(+/-)-,(+)-和(-)-5e]在小鼠中不产生任何子宫反应,能够弱抑制DMBA诱导的乳腺癌的生长那只老鼠 (+/-)-5e对MCF-7细胞的抑制作用,己烯雌酚可以克服,
