bacteria is an urgent subject. Herein, we report a step-economical and diversity-oriented synthesis of a series of 2-arylidenehydrazinyl-4-arylthiazole and 2-arylidenehydrazinyl-5-arylthiazole analogues that utilizes C–Hcoupling methodologies. A library of 54 new congeners were synthesized and tested for their biological potential. Moreover, new knowledge regarding the structure–activity relationships (SARs)

Sirtiun 5 (SIRT5) is a NAD+-dependent protein lysinedeacylase. It is emerging as a promising target for the development of drugs to treat cancer and metabolism-related diseases. In this study, we screened 5000 compounds and identified a hit compound 14 bearing a pyrazolone functional group as a novel SIRT5-selective inhibitor. Structure-based optimization of 14 resulted in compound 47 with an IC50
Sirtiun 5 (SIRT5) 是一种 NAD +依赖性蛋白赖氨酸脱酰酶。它正在成为开发治疗癌症和代谢相关疾病的药物的一个有前景的目标。在这项研究中,我们筛选了 5000 种化合物,并鉴定出带有吡唑啉酮官能团的热门化合物14作为新型 SIRT5 选择性抑制剂。对14进行基于结构的优化,得到化合物47,其 IC 50值为 0.21 ± 0.02 μM,效力提高了 100 倍。与 SIRT1-3 和 SIRT6 相比,化合物47对 SIRT5 显示出显着的选择性。生化研究表明47不占据 NAD + 结合袋并充当底物竞争性抑制剂。已确定的有效且选择性的 SIRT5 抑制剂可以作为研究工具和治疗剂进行进一步研究。
