Estrogen/progestogen Receptor;Progesterone Receptor;Estrogen/progestogenReceptor |
體內(nèi)研究: |
The potency of Nestorone was over 100-fold higher upon s.c. administration than via the oral route. Nestorone showed no androgenic or anabolic activity. Nestorone did not bind to sex hormone binding globulin (SHBG). In contrast to estradiol and levonorgestrel, Nestorone showed no uterotropic activity in ovariectomized rats. Despite significant binding to glucocorticoid receptors (GR), Nestorone showed no glucocorticoid activity in vivo |
動(dòng)物實(shí)驗(yàn): |
Immature female rats were ovariectomized under methoxylflurane anesthesia, randomly distributed into treatment groups (n 5 6 per group), and used 5 to 7 days later. Levonorgestrel or Nestorone (1 or 5 mg) was injected s.c. daily for 5 days. Vaginal lavages were examined microscopically to detect vaginal cornification. The animals were killed on day 6, and the uteri were removed, cleaned, blotted dry, and weighed. The antiestrogenic effects of levonorgestrel and Nestorone were determined in rats receiving 1.0 mg E2. A positive control group received E2 alone. Negative controls received the vehicle |
