  Estradiol-16α-carboxylic Acid Esters as Locally Active Estrogens

  摘要：

  We attempted to design analogues of estradiol to act as locally active estrogens without significant systemic action. We synthesized a series of 16a-carboxylic acid substituted steroids and their esters and tested their action in several assays of estrogenic action, including estrogen receptor (ER) binding, estrogenic potency in Ishikawa cells (human endometrial carcinoma), rat uterine weight (systemic action), and mouse vaginal reductases (local action). All of the estradiol substituted carboxylic acids (formic, acetic and propionic acids) were devoid of estrogenic action. To the contrary, many of the esters had marked estrogenic potency in the receptor and the Ishikawa assays. The esters of the 16 alpha -formic acid series had the highest ER affinity with little difference between the straight-chain alcohol esters (from methyl to n-butyl). However, estrogenic action in the Ishikawa assay decreased precipitously with esters longer than the ethyl ester. This decrease correlated well with the increased rate of esterase hydrolysis of longer esters as determined in incubations with rat hepatic microsomes. The most promising candidates, the methyl, ethyl, and fluoroethyl esters of the formate series, were tested for systemic and local action in the in vivo models. All three, especially the fluoroethyl ester, showed divergence between systemic and local estrogenic action. These metabolically labile estrogens will be extremely useful for the therapeutic treatment of the vaginal dyspareunia of menopause in women for whom systemic estrogens are contraindicated.

  The present invention relates to analogs of estradiol, which, in their most preferred embodiment, act as locally active estrogens without significant systemic action. A series of 16&agr;-carboxylic acid substituted steroids and their esters is presented which exhibit excellent biological activity for use in pharmaceutical compositions for the treatment of symptomology associated with menopause. The present invention is therefore directed to compounds according to the structure: 1 Where R is H, a C 1 to C 5 alkyl, vinyl, CF 3 , CH 2 CH 2 F, CH 2 CHF 2 or CH 2 CF 3 ; and m is from 0-2, or a pharmaceutically acceptable salt thereof. Preferably, R is methyl, ethyl, propyl, iso-propyl, butyl, iso-butyl, pentyl, neo-pentyl, vinyl, CF 3 , CH 2 CH 2 F, CH 2 CHF 2 or CH 2 CF 3 and m is 0. More preferably, R is methyl, ethyl, CH 2 CH 2 F, CH 2 CHF 2 or CH 2 CF 3 and m is 0.

  本发明涉及雌二醇的类似物，其中在其最优选实施例中，作为局部活性雌激素而无显著的全身作用。提供了一系列16α-羧酸取代类固醇及其酯，其表现出优异的生物活性，可用于制备用于治疗与绝经症状相关的药物组合物。因此，本发明针对的是以下结构的化合物：1其中R是H、C1到C5烷基、乙烯基、CF3、CH2CH2F、CH2CHF2或CH2 ；m为0-2，或其药学上可接受的盐。优选地，R为甲基、乙基、丙基、异丙基、丁基、异丁基、戊基、新戊基、乙烯基、 、CH2CH2F、CH2CHF2或CH2 ，m为0。更优选地，R为甲基、乙基、CH2CH2F、CH2CHF2或CH2 ，m为0。
