Carboxylic acid derivatives having potent retinoid-type pharmacological activities are disclosed. The compounds disclosed are represented by the following formula:
wherein R¹, R², and R³ independently represent a hydrogen atom or an alkyl group with the exception that all of R¹, R², and R³ do not simultaneously represent hydrogen atoms and R¹ together with R² optionally represent a cyclic structure formed by the combination thereof; R⁴ represents a hydrogen atom or an alkyl group; X represents a nitrogen atom or C-OH; and A represents -CO-NH- or -NH-CO-.
揭示了具有强效视黄醇类药理活性的羧酸衍生物。所揭示的化合物由以下公式表示:其中R¹、R²和R³独立地代表氢原子或烷基基团,除非R¹、R²和R³中的所有原子同时代表氢原子,且R¹和R²一起可选地代表由它们的组合形成的环结构;R⁴代表氢原子或烷基基团;X代表氮原子或C-OH;A代表-CO-NH-或-NH-CO-。
