date, limited SAR studies have focused on the quinoline ring (A-ring), and as such, we set out to explore modifications within this region in an attempt to discover new bedaquiline variants with an improved safety profile. We herein report the development of unique synthetic strategies that facilitated access to novel bedaquiline analogues leading to the discovery that anti-tubercular activity could
尽管疗效有希望,但由于安全问题,抗结核治疗药物贝达喹啉的临床使用受到限制。迄今为止,有限的 SAR 研究集中在喹啉环(A 环)上,因此,我们着手探索该区域内的修饰,以尝试发现具有改进安全性的新贝达喹啉变体。我们在此报告了促进获得新型贝达喹啉类似物的独特合成策略的发展,从而发现在用吡啶杂环取代喹啉基序后可以保留抗结核活性。预计这一发现将为探索改进的抗结核疗法的设计开辟多种新途径。

[Problem]To provide a therapeutic agent for irritable bowel syndrome (IBS), which is excellent in efficacy and safety.
[Means for Resolution]It was shown that the bombesin 2 (BB2) receptor antagonists typified by RC-3095 are therapeutic agents for irritable bowel syndrome (IBS), which show excellent efficacy in both of an abdominal symptom and bowel movement disorder. Thus, according to the present invention, it became possible to provide a therapeutic agent for irritable bowel syndrome (IBS) which comprises, as an active ingredient, a bombesin 2 (BB2) receptor antagonist exerting an excellent efficacy in both an abdominal symptom and bowel movement disorder.
