A series of aminothiazole derivatives bearing the benzimidazole moiety were synthesized and evaluated in Gli luciferase reporter assays. Lead optimization led to the discovery of potent hedgehog pathway antagonist 18 (2‐[3‐(1H‐benzimidazol‐2‐yl)‐4‐chloroanilino]‐N‐[4‐(trifluoromethyl)phenyl]‐1,3‐thiazole‐4‐carboxamide), with IC50 values in nanomolar range. The molecular basis ascribed to hindering
一系列带有苯并咪唑部分的氨基噻唑衍生物被合成并在 Gli 荧光素酶报告基因检测中进行评估。先导优化导致发现了强效刺猬通路拮抗剂 18 (2-[3-(1H-benzimidazol-2-yl)-4-chloroanilino]-N-[4-(trifluoromethyl)phenyl]-1,3-thiazole- 4-甲酰胺),IC50 值在纳摩尔范围内。分子基础归因于阻碍声波刺猬驱动的平滑 (Smo) 在初级纤毛 (PC) 内的定位。此外,化合物 18 抑制突变 Smo 细胞系中 Gli1 mRNA 的表达,并显示出对 DAOY 癌细胞的中等细胞毒性。
