2‐dihydro‐3H‐naphth[1,2‐e][1,3]oxazine‐3‐thione by a molecular modeling approach. Docking studies were conducted with structural data from crystallized human SIRT2 enzyme. Subsequent evaluation of the in silico hypotheses through synthesis and biological evaluation of the designed structures was accomplished with the aim to discover new SIRT2 inhibitors with improved aqueous solubility. Derivatives of 8‐bromo‐1
杂环芳烃筛选命中的非极性衍生物,如非选择性沉默调节蛋白抑制剂 splitomicin,在生物体液中的溶解性较差。与富含 sp3 的天然产物不同,扁平芳香族化合物易于堆积,并且通常难以优化为在细胞系统中具有活性的先导化合物。这项工作的目的是确定将具有极性官能团的富含 sp3 的片段引入新发现的活性(IC50 = 5 μM)但非极性支架 1,2-dihydro-3H-naphth[1,2- e][1,3]oxazine-3-thione 通过分子建模方法。对接研究使用来自结晶的人 SIRT2 酶的结构数据进行。随后通过对设计结构的合成和生物学评估对计算机假设进行了评估,目的是发现具有改善的水溶性的新 SIRT2 抑制剂。8-bromo-1,2-dihydro-3H-naphth[1,2-e][1,3]oxazine-3-thone N-烷基化的衍生物,在硫代氨基甲酸酯基团上带有亲水性吗啉-烷基
