tipifarnib (1) has been synthesized as inhibitors of FTase by substituting the benzimidazolones and indoles for the 2-quinolone of tipifarnib. The novel benzimidazolones are potent and selective FTase inhibitors (FTIs) with IC(50) values of the best compounds close to that of tipifarnib. The current series demonstrate good cellular activity as measured in their inhibiting the Ras processing in NIH-3T3 cells
通过用苯并咪唑酮和吲哚取代替非法尼的2-喹诺酮,合成了一系列替非法尼(1)的类似物作为FTase抑制剂。新型苯并咪唑酮类是有效的选择性FTase抑制剂(FTI),最佳化合物的IC(50)值接近于Tipifarnib。当前的系列显示出良好的细胞活性,因为它们抑制了NIH-3T3细胞中的Ras加工,化合物2c和2f的EC(50)值分别为18nM和22nM。
