  Synthesis and evaluation of a new series of mechanism-based aromatase inhibitors

  摘要：

  A series of new 4-(alkylthio)-substituted androstenedione analogues was designed as potential suicide inhibitors of aromatase on the basis of mechanistic considerations on the mode of action of the enzyme. Their synthesis and biological evaluation are described. Among the most interesting are the 4-[(difluoromethyl)thio]-, 4-[(fluoromethyl) thio]-, and 4-[(chloromethyl)thio]androstenediones 12,13, and 14 with respective IC50's of 2.7,0.8, and 0.94-mu-M. Compound 12 was a reversible inhibitor of aromatase while compounds 13 and 14 displayed time-dependent kinetics of inhibition with respective K(I)'s and half-times of inactivation of 30 nM and 3.75 min for 13 and 30 nM and 3 min for 14. The inhibition of aromatase by 14 was NADPH-dependent, and was protected by the presence of substrate (0.5-1-mu-M), while beta-mercaptoethanol (0.5 mM) failed to protect the enzyme from inactivation. Dialysis failed to reactivate aromatase previously inactivated by 14. The mechanistic implications of these findings are

• Methods and compositions for the treatment of estrogen-dependent hyperproliferative uterine disorders

  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。
