Novel 2-amino-3-(5- and 6-)benzoylphenylacetic acids, esters and metal salts of the formula: ##STR1## wherein R is hydrogen or lower alkyl, R.sup.1 is hydrogen, lower-alkyl, sodium or potassium, R.sup.2 is hydrogen, halogen or lower alkoxy, X is hydrogen, lower alkyl, halogen, nitro or trifluoromethyl, Y is hydrogen, lower alkyl, halogen, nitro or trifluoromethyl, and Am is primary amino (--NH.sub.2) methylamino or dimethylamino. The compounds are prepared by hydrolysis of 4-(5- and 7-)benzoylindolin-2-ones to give the 2-amino-3-(5- and 6-)benzoylphenylacetic acids wherein amino is primary amino. The free acids are converted to the esters and metal salts. The calcium and magnesium salts are disclosed and are within the scope of the present invention. The compounds have anti-inflammatory activity, are effective in lowering the cholesterol levels in hyperlipemic rats and inhibit blood platelet aggregation.
化合物的公式为:##STR1## 其中R为氢或低碳基,R.sup.1为氢,低碳基,钠或钾,R.sup.2为氢,卤素或低烷氧基,X为氢,低碳基,卤素,硝基或三氟甲基,Y为氢,低碳基,卤素,硝基或三氟甲基,Am为一级氨基(--NH.sub.2)甲基氨基或二甲基氨基。这些化合物通过4-(5-和7-)苯甲酰吲哚-2-酮的水解制备而成,得到二氨基-3-(5-和6-)苯甲酰基乙酸,其中氨基为一级氨基。游离酸转化为酯和金属盐。本发明揭示了钙和镁盐,并在本发明的范围内。这些化合物具有抗炎活性,在高脂血鼠中有效降低胆固醇水平并抑制血小板聚集。
