摘要/Abstract

设计并合成了一系列FGF401类似物以研究其FGFR4抑制、抗肿瘤活性及其构效关系.研究发现了N-（5-氰基-4-（（2-甲氧基乙基氨基）吡啶-2-基）-7-甲酰基-6-（（N-甲基四氢吡喃-4-甲酰胺）甲基-1，2，3，4-四氢-1，8-萘啶-1-甲酰胺（8ac）不仅在酶和细胞学水平上对FGFR4具有强效的的抑制活性，并表现出了出色的选择性.其活性及选择性优于阳性对照FGF401，并且在HCC（hepatocellular carcinoma）动物移植瘤模型中显著抑制肿瘤生长，还引起了肿瘤萎缩.

A set of analogues of FRF401 were designed and synthesized, and their FGFR4 inhibition and antitumor activity as well as the structure-activity relationship (SAR) studies were screened. It was found that N-(5-cyano-4-((2-methoxyethyl)-amino)pyridin-2-yl)-7-formyl-6-((N-methyltetrahydro-2H-pyran-4-carboxamido)methyl)-1,2,3,4-tetrahydro-1,8-naphthyridine-1-carboxamide (8ac) not only showed superior FGFR4 inhibitory activity compared with FGF401 and excellent selectivity in enzymatic and cellular level, but also dramatically inhibited tumor growth and induced tumor regression in hepatocellular carcinoma xenograft model.
Key words: selective FGFR4 inhibitor, analogues of FRF401, structure-activity relationship, hepatocellular carcinoma
