  Synthesis and biochemical studies of 16- or 19-substituted androst-4-enes as aromatase inhibitors

  摘要：

  Androst-4-en-17-one derivatives [19-acetoxide 4, 16-bromides 14 and 15, 19,19-difluoride 18, and (19R,S)-19-acetylenic alcohol 25] and androst-4-en-17-beta-ol derivatives 3, 5, 10, 12, and 19 were synthesized and tested for their ability to inhibit aromatase in human placental microsomes. All the 17-oxo steroids, except compound 25 and 17,19-diol 3 of this series, were effective competitive inhibitors with apparent K(i)'s ranging from 170 to 455 nM. 19,19-Difluoro steroid 18 and 19-acetylenic alcohol 25, a weak competitive inhibitor (K(i) = 7.75-mu-M), caused a time-dependent, pseudo-first-order inactivation of aromatase activity with k(inact)'s of 0.0213 and 0.1053 min-1 for compounds 18 and 25, respectively. NADPH and oxygen were required for the time-dependent inactivation, and the substrate, androst-4-ene-3,17-dione, prevented it, but a nucleophile, L-cysteine, did not in each case. The results strongly suggest that aromatase would attack the 19-carbon of steroids 18 and 25.

  The present invention relates to the treatment of estrogen-dependent hyperproliferative uterine disorders including endometriosis, uterine fibroids, endometrial hyperplasia, uterine cancer, and their related symptoms by intravaginally administering at least two active agents selected from an aromatase inhibitor, an antiinflammatory agent, and a uterine-selective estrogen receptor antagonist. This combination therapy reduces local estrogen production, blocks local estrogen action, and suppresses inflammation locally, resulting in starvation of the estrogen-dependent diseased tissues, relief of related symptoms, and retardation of disease progression. Intravaginal delivery maximizes local inhibition of estrogen production without significantly affecting systemic circulating estrogen levels. This results in enhanced clinical efficacy and reduced side effects.

  本发明涉及治疗依赖雌激素的子宫过度增生性疾病，包括子宫内膜异位症、子宫肌瘤、子宫内膜增生、子宫癌及其相关症状，通过阴道给药至少两种活性药物，所选药物包括芳香化酶抑制剂、抗炎药和子宫选择性雌激素受体拮抗剂。这种联合疗法降低了局部雌激素产生，阻断了局部雌激素作用，并在局部抑制了炎症，导致对依赖雌激素的疾病组织的饥饿，缓解相关症状，延缓疾病进展。阴道给药最大限度地抑制了局部雌激素产生，而不显著影响全身循环雌激素水平。这导致增强的临床疗效和减少的副作用。
