2-phenylindole derivatives with one hydroxy group in the meta or para position of the phenyl ring and a second one in position 5, 6, or 7 of the indole nucleus were synthesized. In addition, different alkyl groups were introduced into positions 1 and 3 of the heterocycle. The influence of these structural variations on the binding affinity for the calf uterine estrogen receptor was studied. A prerequisite
合成了许多2-苯基吲哚衍生物,其在苯环的间位或对位具有一个羟基,在吲哚核的5、6或7位具有第二个羟基。另外,将不同的烷基引入杂环的1和3位。研究了这些结构变化对小牛子宫雌激素受体结合亲和力的影响。结合的前提条件是在氮原子上存在烷基。位于苯环对位的羟基和在吲哚的1和3位的短烷基链是有利的。最高相对结合亲和力(RBA)值(例如20b为33、24b为21、35b为23)接近己烯雌酚(RBA = 25,雌二醇= 100)。根据氧官能团的位置和烷基残基的大小,吲哚衍生物在化合物中表现为强雌激素(20c,24c,35c)或受阻雌激素,具有拮抗活性(23c,29c,30c,31c,40c,44c)。未成熟的鼠标。测试了其中一些衍生物(20c,23c,24c,29c,30c,31c)对二甲基苯并蒽诱导的激素依赖性大鼠乳腺肿瘤的抑制作用。两种类型均显示出强烈的生长抑制作用,在适当的剂量下平均肿瘤面积减小。假
