A method of treating steroid-dependent disease such as prostate cancer in a subject is described that includes administering a therapeutically effective amount a CYP17A inhibitor and an effective amount of a 5- -reductase inhibitor to the subject.
The present invention relates to processes for obtaining abiraterone and derivatives thereof, such as abiraterone acetate, by means of a Suzuki coupling through a steroid borate of general formula (IV) or a C—C coupling through a steroid hydrazone of general formula (II), as well as to intermediates useful in said processes.

The present invention relates to a novel process for the synthesis of abiraterone and in particular abiraterone acetate, a compound of formula (I) reported below: having pharmacological activity suitable for slowing down the progression of advanced stage prostate cancer. The process is characaterised by the fact that the intermediate triflation step is carried out on prasterone (DHEA) or its 3-acetate using Ar-N(OTf)2 as the triflation reagent, but where Ar is not phenyl, and by the fact that the base used in this step is an alkali metal alcoholate.
本发明涉及一种用于合成阿比特龙及特别是阿比特龙乙酸酯的新型方法,该化合物的结构式如下:具有适用于减缓晚期前列腺癌进展的药理活性。该方法的特点在于,在中间三氟甲基化步骤中,采用 Ar-N(OTf)2 作为三氟甲基化试剂,在脱氢表雄酮(DHEA)或其 3-醋酸酯上进行,其中 Ar 不是苯,并且在这一步中使用的碱是碱金属醇盐。
Steroidal C-17 nitrogen-containing heterocycles of Formula I:,wherein: the ABCD ring structure is the nucleus of a steroid, or an analog thereof,; X is a group capable of coordinating a heme group of CYP 17, and Y is an hydroxyl functionality, a suitable ester, or a prodrug group, for the treatment of urogenital and/or androgen-related cancers, such as castration-resistant prostate cancer. The invention provides methods of synthesizing new chemical entities and methods of using the same in treating urogenital and/or androgen-related cancers.
