A novel series of pyrazolo[1,5-a]pyrimidines bearing a 3-hydroxyphenyl group at C(3) and substituted tropanes at C(7) have been identified as potent B-Raf inhibitors. Exploration of alternative functional groups as a replacement for the C(3) phenol demonstrated indazole to be an effective isostere. Several compounds possessing substituted indazole residues, such as 4e, 4p, and 4r, potently inhibited
一种新型的吡唑并[1,5- a ]嘧啶在C(3)处带有3-羟基苯基,在C(7)处具有取代的托烷类被确定为有效的B-Raf抑制剂。探索替代的官能团,以取代C(3)酚证明吲唑是有效的等排物。几种具有取代的吲唑残基的化合物(例如4e,4p和4r)在亚微摩尔浓度下可有效抑制A375和WM266细胞系中的细胞增殖,后两种化合物在细胞中也表现出良好的治疗指数。
