4-(1-R'-2-phenyl-1H-indol-3-yl)-3-cyclohexene-1-carboxylic acids, 4-(1'R'-2-phenyl-1H-indol-3-yl)cyclohexane-1-carboxylic acids, 4-(1-R'-2-phenyl-1H-indol-3-yl)benzoic acids, the corresponding cyclohexene- and cyclohexane-1,1-dicarboxylic acids, and lower-alkyl esters thereof, wherein R' is hydrogen or lower-alkyl, are prepared by reacting a 1-R'-2-phenyl-1H-indole with a cyclohexanone-4-carboxylic acid or -4,4-dicarboxylic acid, followed as desired by a hydrogenation or aromatization process. The compounds which are free carboxylic acids or salts thereof are useful as complement inhibitors. The corresponding esters are useful as intermediates.
