Novel 3,4-disubstituted-N-acylanilines of the formula:
wherein Rl, R2 and ring A are defined in claim 1;
wherein R3 is hydrogen or alkyl of up to 4 carbon atoms, or is joined to R5 as stated below;
wherein R4 is alkyl of 2 to 4 carbon atoms, or has the formula -CX1X2X3 wherein X1, X2 and X3, which may be the same or different, each is hydrogen, fluorine or chlorine;
wherein R5 is hydrogen, hydroxy or alkoxy or acyloxy each of up to 15 carbon atoms, or is joined to R3 to form an oxycarbonyl group such that together with the I -N-CO-C- part of the molecule it forms an oxazolidinedione group; and
wherein R6 is hydrogen or halogen. These compounds possess antiandrogenic activity and are useful for the treatment of androgen dependent or prostatic diseases. Representative of the compounds is 3,4-dichloro-N-(2-hydroxy-2-p-nitrophenylpropionyl)aniline. Also disclosed are processes for the manufacture of the compounds and pharmaceutical and veterinary compositions containing them.
式中的新型 3,4-二取代-N-酰基苯胺:
其中 Rl、R2 和环 A 在权利要求 1 中定义;
其中 R3 是氢或最多 4 个碳原子的烷基,或如下所述与 R5 连接;
其中 R4 是 2 至 4 个碳原子的烷基,或具有式 -CX1X2X3 其中 X1、X2 和 X3 可以相同或不同,各自是氢、氟或氯;
其中 R5 是氢、羟基或烷氧基或酰氧基,每个最多有 15 个碳原子,或与 R3 连接形成氧羰基,从而与分子的 I -N-CO-C- 部分一起形成噁唑烷二酮基团;以及
其中 R6 为氢或卤素。这些化合物具有抗雄激素活性,可用于治疗雄激素依赖性疾病或前列腺疾病。其中具有代表性的化合物是 3,4-二氯-N-(2-羟基-2-对硝基苯丙酰基)苯胺。此外,还公开了这些化合物的生产工艺以及含有这些化合物的药物和兽药组合物。
