tested as potential postcoital antifertility agents. Estrogen-relative binding affinities were determined, in vivo assays for estrogenic and postcoital antifertility activity were conducted in rats, and selected candidate compounds were further tested for estrogenic activity in monkeys. In the rat, the 17-desoxyestratriene derivatives 8a, 8b, and 30 have shown low estrogenic activity while retaining potent
已合成了一系列17-取代的17-脱氧雌三烯酮,并已作为潜在的性交后抗生育药进行了测试。确定雌激素相对结合亲和力,在大鼠中进行雌激素和性交后抗生育活性的体内测定,并进一步测试选定的候选化合物在猴子中的雌激素活性。在大鼠中,17-脱氧雌三烯衍生物8a,8b和30显示出低雌激素活性,同时保留了有效的抗生育活性。一开始的结构修饰包括各种17-取代基和17-氧官能度的缺失,以前认为这对于有效活性是必需的。17β-乙基侧链表现出最大的抗生育活性和最大的雌激素分离率。
