substituted 2-aminophenylacetic acid derivatives were prepared and tested for in vitro prostaglandin synthetase inhibition activity and for in vivo antiinflammatoryactivity. The 2-amino substituent is beneficial to potency in the inhibition of prostaglandin synthetase for the 3-phenoxy, 4-phenyl, and 3-benzoyl series, but only the 3-benzoyl series shows increased antiinflammatory potency in the in vivo assay

Novel 2-aminobiphenylacetic acids, esters and metal salts of the formula are disclosed: ##STR1## wherein R represents hydrogen, lower alkyl, sodium or potassium; R.sup.1 represents fluoro, chloro, bromo, lower-alkyl or amino; R.sup.2 represents lower-alkyl, lower-alkoxy, fluoro, chloro, bromo, amino or trifluoromethyl; and m and n are 0-2 with the proviso that when R.sup.1 or R.sup.2 are tertiary butyl or a sterically hindering lower alkyl radical, m and/or n are 1. The compounds are prepared by hydrolysis of 4-(5-, 6- and 7-)phenylindolin-2-ones to give the 2-amino-3-(4-, 5- and 6-)biphenylacetic acids. The free acids are converted to the esters and metal salts. The compounds have anti-inflammatory activity and inhibit blood platelet aggregation.
