A compound has inhibitory activity on Discoidin Domain Receptor 1. A urea derivative is represented by the formula (I) or a pharmaceutically acceptable salt thereof:
wherein, R1 is trifluoromethyl, trifluoromethoxy, or pentafluorosulfanyl; each R2 is independently a hydrogen atom or methyl which is optionally substituted by one hydroxyl or one saturated heterocyclyl having four to six ring-forming atoms; R3 is a hydrogen atom, halogen atom, C1-C3 alkyl, saturated heterocyclyl having four to six ring-forming atoms and optionally having an oxo group, or R5O—; and R4 is phenyl, pyridyl, pyridazinyl, or pyrimidinyl, which phenyl, pyridyl, pyridazinyl, or pyrimidinyl is optionally substituted by one R6.
一种化合物对 Discoidin Domain Receptor 1 具有抑制活性。脲衍生物由式(I)或其药学上可接受的盐表示:
其中,R1 是三氟甲基、三氟甲氧基或五氟硫酰基;每个 R2 独立地是氢原子或甲基,可选择被一个羟基或一个具有四至六个成环原子的饱和杂环基取代;R3 是氢原子、卤素原子、C1-C3 烷基、具有四至六个成环原子且可选具有一个氧代基团的饱和杂环基,或 R5O-;以及 R4 是苯基、吡啶基、哒嗪基或嘧啶基,其中苯基、吡啶基、哒嗪基或嘧啶基可选被一个 R6 取代。
