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 15α-estradiol ester compounds 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:
where X is
R is H, a C1 to C5 alkyl group, optionally substituted with at least one halogen group, such as CH2CH2F, or other group (e.g., CH2CHF2, CH2CF3 or CF3 group); and
m is from 0–5, preferably from 0–2.
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
雌激素而没有显著的全身作用。提供了一系列15
α-雌二醇酯化合物,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,本发明针对的化合物的结构如下:其中X是R是H,C1至C5烷基,可选地被至少一个卤素基取代,例如CH2CH2F或其他基团(例如CH2CHF2,CH2 或
CF3基团);而m为0-5,优选为0-2。
