    • The present invention relates to steroidal esters of 17-oximino-5-androsten-3-ol, of compound of general formula (A) wherein R is selected from a group consisting of arylalkyl, aryl, substituted aryl. The ester derivatives are synthesized starting from Dehydroandrosterone acetate. The compounds were tested for their antiproliferative activity and 5α-reductase inhibitory activity in comparison to Finasteride. Decreased androgen level have been found in serum of animal treated with newly synthesized compounds. These compounds have also shown better cytotoxicity in comparison to reference drug Finasteride. Thus such compounds can be useful in treatment of androgen dependent disorder of prostate alone or by synergistic effect they can decrease the size of prostate due to their antiproliferative activity.
    • 本发明涉及通式(A)化合物,其中R选自芳烷基,芳基,取代芳基的17-肟基-5-雄甾-3-醇类甾体酯。 酯衍生物是从乙酸脱氢睾酮开始合成的。 与非那雄胺相比,测试了这些化合物的抗增殖活性和5α-还原酶抑制活性。 在新合成的化合物处理的动物血清中发现雄激素水平降低。 与参考药物非那雄胺相比,这些化合物也显示出更好的细胞毒性。 因此,这样的化合物可用于治疗前列腺单独的雄激素依赖性病症或通过协同作用,由于它们的抗增殖活性,它们可以减少前列腺的大小。

    • Compounds of structural Formula (I) and pharmacologically acceptable salts and esters thereof possess 5α-reductase inhibitory activity. These compounds inhibit 5α-reductase type 1 and type 2. The compounds of structural Formula I are useful in the systemic, including oral, and parenteral, including topical, treatment and prevention of hyperandrogenic conditions including prostatic carcinoma, benign prostatic hyperplasia, acne vulgaris, seborrhea, androgenic alopecia (also called androgenetic alopecia) which includes male- and female-pattern baldness, female hirsutism, and prostatitis. A class of compounds of the present invention are also potent antiandrogens. The present invention also relates to novel compositions containing such compounds, methods of their use and methods of their manufacture.
    • 结构式(I)的化合物及其药理学上可接受的盐和酯具有5α-还原酶抑制活性。 这些化合物抑制1型和2型5α-还原酶。结构式I的化合物可用于全身,包括口服和肠胃外,包括局部治疗和预防高雄激素症状,包括前列腺癌,良性前列腺增生症,寻常痤疮, 皮脂溢,雄激素性脱发(也称雄激素性脱发),包括男性和女性型秃发,女性多毛症和前列腺炎。 一类本发明的化合物也是有效的抗雄激素。 本发明还涉及含有这些化合物的新型组合物,其用途及其制备方法。
