Provided is a novel and excellent method for treating and/or preventing benign prostatic hyperplasia, prostate cancer, and the like based on selective inhibitory activity against 17βHSD type 5. It was found that an indole or benzimidazole derivative, where a nitrogen atom of the indole ring or benzimidazole ring is substituted with a phenyl group substituted with COOH, has a potent selective inhibitory activity against 17βHSD type 5 and may become an agent for treating and/or an agent for preventing a disease associated with 17βHSD type 5, such as benign prostatic hyperplasia, prostate cancer and the like, without accompanying adverse effects due to a decrease in testosterone; and the present invention has thus been completed.
提供了一种治疗和/或预防良性前列腺增生、前列腺癌等疾病的新颖和优异方法,该方法基于对17βHSD type 5的选择性抑制活性。发现一种吲哚或苯并咪唑衍生物,其中吲哚环或苯并咪唑环的氮原子被取代为一个带有COOH的苯基,具有强大的17βHSD type 5的选择性抑制活性,并可以成为治疗和/或预防与17βHSD type 5相关的疾病,如良性前列腺增生、前列腺癌等的药物,而不伴随着睾酮降低引起的不良影响;因此,本发明得以完成。
