Phenylacetic acid derivatives of the formula ##STR1## wherein n is an integer of 2 to 5; ##STR2## R.sub.1 is hydrogen, halogen, trifluoromethyl, nitro or amino; R.sub.2 and R.sub.3 each independently is hydrogen or lower alkyl; or together form an ethylene group; X.sub.1 represents two hydrogen atoms or an oxo group; and Y.sub.1 is cyano, hydroxyamidocarbonyl, carbamoyl, 5-tetrazolyl or carboxyl; and for derivatives wherein Y is carboxyl, salts thereof with physiologically compatible bases, esters thereof from physiologically acceptable alcohols and amides thereof from physiologically acceptable amines have valuable pharmacological activity, e.g., as antiinflammatory agents.
苯乙酸衍生物的化学式如下:其中n为2至5的整数;R.sub.1为氢、卤素、三氟甲基、硝基或氨基;R.sub.2和R.sub.3各自独立地为氢或较低的烷基;或者一起形成一个乙烯基;X.sub.1代表两个氢原子或一个氧代基团;Y.sub.1为氰基、羟基酰胺基甲酰、氨基甲酰、5-四唑基或羧基;对于Y为羧基的衍生物,其与生理兼容碱盐、与生理上可接受的醇酯和与生理上可接受的胺酰衍生物具有有价值的药理活性,例如作为抗炎药物。
