[Object] A screening method for a compound which is useful as an agent for treating 17βHSD type 5-related diseases and/or an agent for treating 17βHSD type 5-related cancer such as prostate cancer is provided.
[Means for Solution] The present invention has been completed by establishing a screening method for a compound which is useful for treating 17βHSD type 5-related diseases, by manifesting a tumor by transplanting tumor cells to, for example, an immunodeficient mouse, topically administering a steroid which is a biosynthetic substance for a hormone into the tumor, and measuring the level of a hormone produced in the tumor.
[Selected Figure] None
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。

Two approaches have been developed for the regiospecific continuous‐flow synthesis of 1‐substituted benzotriazoles. They begin with either an SNAr reaction at high temperature or Pd catalysis and involve consecutive multiphase processes, allowing the multistep synthesis of benzotriazoles to take place in an efficient manner (see picture).
已经开发出两种方法用于1-取代的苯并三唑的区域特异性连续流动合成。它们从高温下的S N Ar反应或Pd催化开始,并且涉及连续的多相过程,从而可以高效地进行苯并三唑的多步合成(见图)。
