synthesized a series of novel 4-aminopiperidine derivatives as SMO/ERK dual inhibitors, and evaluated their biological activities. The results showed that compounds I-13 displayed strong inhibitory activities towards both SMO and ERK, and it also exhibited significant cytotoxicity against human cholangiocarcinoma RBE cells which overexpress both the Hh and ERK pathways. All the results indicate that
hedgehog(Hh)信号通路与多种癌症的形成、转移和复发密切相关,使其成为理想的抗癌靶点。Smoothened (SMO) 是其主要成员之一。三种靶向Hh通路的药物已成功应用于临床,均称为SMO抑制剂。但严重的耐药问题限制了其临床应用。致癌ERK通路与Hh通路以多种方式相互作用已被证明是导致耐药的主要因素之一。Hh 和 ERK 通路的双重抑制显示出对过表达这两种通路的癌细胞的协同抑制。在此,我们设计并合成了一系列作为 SMO/ERK 双重抑制剂的新型 4-氨基哌啶衍生物,并评价了它们的生物活性。I-13对 SMO 和 ERK 均表现出强烈的抑制活性,并且它对过表达 Hh 和 ERK 通路的人胆管癌细胞 RBE 细胞也表现出显着的细胞毒性。所有结果表明,化合物I-13作为 SMO/ERK 双重抑制剂是一种很有前途的抗癌候选药物。
