N-Sulfonyl-N'-benzimidazol-2-yl acetamidines have been designed as CK1 inhibitors. Binding modes in the ATP pocket of CK1 were determined by molecular modeling. The synthetic approach involves sequential acylation of 2-aminobenzimidazoles followed by reaction of amides with Lawesson’s reagent and iminosulfonylation of thioamides with sulfonyl azides. The iminosulfonylation was carried out in boiling
N-磺酰基-N'-苯并咪唑-2-基乙脒被设计为CK1抑制剂。CK1 ATP 袋中的结合模式由分子模型确定。合成方法包括 2-氨基苯并咪唑的顺序酰化,然后酰胺与劳森试剂反应,硫代酰胺与磺酰叠氮化物的亚氨基磺酰化。亚氨基磺酰化在沸腾的乙醇中进行,叠氮化物和硫代酰胺的比例相等。测试合成的化合物在体外抑制 CK1 同种型和抑制肿瘤细胞系生长的能力。在合成的化合物中,有两种产物对 CK1δ 和 CK1ε 表现出抑制能力。
