Optimization of NAMPT (Nicotinamide Phosphoribosyltransferase) Activators: Discovery of N,N-Diethyl-1,2-benzoxazole-3-carboxamide Derivatives as Potent NAMPT Activators with Mitigated Mutagenic Risks
DS68702229, a potent NAMPT activator developed from HTS followed by a hit-to-lead campaign, is a promising candidate compound that significantly reduced body weight when orally administered to mice with high fat diet-induced obesity. However, in vitro toxicology profiling of DS68702229 revealed bacterial mutagenicity using Salmonella typhimurium TA98 and TA100 strains upon S9 activation. Hypothesizing
DS68702229是一种从 HTS 开发的强效 NAMPT 激活剂,随后进行了一次打击领先运动,是一种很有前途的候选化合物,当口服给予高脂饮食诱导的肥胖小鼠时,可显着降低体重。然而,DS68702229的体外毒理学分析揭示了使用鼠伤寒沙门氏菌TA98 和 TA100 菌株在 S9 激活后的细菌致突变性。假设 DNA 嵌入是可能的原因,我们采用了几种方法来破坏推定的 DNA 嵌入,包括调节分子形状。我们的努力最终发现了化合物20k和20l ,它们增加了细胞内 NAD +在不诱导致突变性的基于细胞的测定中的水平,以及口服给药后小鼠中可接受的血浆暴露。
