6-dichloro-substituted compounds exhibit for N-CH3 (2e, 3e), N-C2H5 (2f, 3f), and N-C3H7 (2g, 3g) an affinity to the estradiol receptor (Ka values ranging from 9.1 X 10(4) to 9.1 X 10(6)), because the nitrogen atoms are shielded by the ortho-located chlorine atoms; therefore, a binding interaction with hydrophobic receptor areas is possible. These substances show weak uterotrophic activity and no significant effect
合成了具有2,4,2,6,3,4和3,5位氯的非对映异构N,N'-二烷基双(二氯苯基)乙二胺和相应的咪唑烷。仅2,6-二氯取代的化合物的立体异构体对N-CH3(2e,3e),N-C2H5(2f,3f)和N-C3H7(2g,3g)表现出对雌二醇受体(Ka值范围从9.1 X 10(4)到9.1 X 10(6)),因为氮原子被邻位氯原子屏蔽;因此,与疏水性受体区域的结合相互作用是可能的。这些物质具有弱的子宫营养能力,并且对DMBA诱导的激素依赖性大鼠乳腺腺癌的生长没有明显影响。
