    • The invention relates to carboxylic acids and derivatives thereof and pharmaceutical compound containing them. The active compounds are represented by the formula compound represented by formula I, wherin R1-R4 each independently represents an unsubstituted or substituted hydrocarbyl or heterocyclyl radical, Q represents a diradical consisting of a linear chain of 11 to 18 carbon atoms, one or more of which may be replaced by heteroatoms, said chain being optionally substituted by inert substituents and one or more of said carbon or heteroatom chain members optionally forming part of a ring structure, and where one or both of the carboxyl groups can be substituted by an in vitro hydrolyzable physiologically acceptable substituent; with the proviso that: compounds wherein R1-R4 each represents CH3 and Q represents a linear chain of 14 carbons, are excluded; and compounds wherein Q represents a linear chain of carbon atoms one of which is replaced by oxygen or sulfur, are excluded. 1
    • 本发明涉及羧酸及其衍生物和含有它们的药物化合物。 活性化合物由式I表示的式化合物表示,R 1 -R 4各自独立地表示未取代或取代的烃基或杂环基,Q表示由11至18个碳原子的直链键组成的双基,其中一个或多个 其可以被杂原子替代,所述链任选被惰性取代基取代,并且一个或多个所述碳或杂原子链构件任选地形成环结构的一部分,并且其中一个或两个羧基可被体外取代 可水解的生理学上可接受的取代基; 条件是:其中R 1 -R 4各自表示CH 3且Q表示14个碳的直链的化合物; 和其中Q表示碳原子的直链链,其中一个被氧或硫取代的化合物被排除。
