Nicotinamide phosphoribosyltransferase (NAMPT) catalyzes the rate-limiting step of the NAD+ salvage pathway. Since NAD+ plays a pivotal role in many biological processes including metabolism and aging, activation of NAMPT is an attractive therapeutic target for treatment of diverse array of diseases. Herein, we report the continued optimization of novel urea-containing derivatives which were identified as potent NAMPT activators. Early optimization of HTS hits afforded compound 12, with a triazolopyridine core, as a lead compound. CYP direct inhibition (DI) was identified as an issue of concern, and was resolved through modulation of lipophilicity to culminate in 1-[2-(1-methyl-1H-pyrazol-5-yl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]-3-(pyridin-4-ylmethyl)urea (21), which showed potent NAMPT activity accompanied with attenuated CYP DI towards multiple CYP isoforms.

1-[2-(1-methyl-1H-pyrazol-5-yl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]-3-(pyridin-4-)的发现ylmethyl)urea 作为一种有效的 NAMPT(烟酰胺磷酸核糖基转移酶)激活剂,具有减弱的 CYP 抑制作用

烟酰胺磷酸核糖基转移酶 (NAMPT) 催化 NAD +补救途径的限速步骤。由于 NAD +在包括新陈代谢和衰老在内的许多生物过程中起着关键作用,因此 NAMPT 的激活是治疗多种疾病的有吸引力的治疗靶点。在此,我们报告了新型含尿素衍生物的持续优化,这些衍生物被鉴定为有效的 NAMPT 激活剂。HTS 命中的早期优化提供了具有三唑并吡啶核心的化合物12作为先导化合物。CYP 直接抑制 (DI) 被确定为一个令人关注的问题,并通过调节亲脂性以最终形成 1-[2-(1-methyl-1H-pyrazol-5-yl)-[1,2,4] 来解决三唑并[1,5- a]pyridin-6-yl]-3-(pyridin-4-ylmethyl)urea ( 21 ),它显示出有效的 NAMPT 活性,同时对多种 CYP 同工型的 CYP DI 减弱。
