This invention concerns novel (4-substituted-2-phenylcyclohexyl)alkenoic and alkanoic acid derivatives of the formula I wherein one of Ra and Rb is hydrogen, hydroxy, (1-6C)alkyl, (1-6C)alkoxy, (3-6C)alkenyloxy or phenyl(1-4C)alkoxy and the other of Ra and Rb is hydrogen, (1-6C)alkyl, (1-6C)alkoxy or (3-6C)alkenyloxy; or Ra and Rb together form a (2-4C)alkylenedioxy or oxo group; benzene ring X optionally bears a substituent selected from halogeno, (1-6C)alkyl, (1-6C)alkoxy, hydroxy, (2-6C)alkanoyloxy, (1-6C)alkanoylamino, trifluoromethyl and nitro; n is 3-5; Y is ethylene or vinylene; and in the cyclohexane ring, the substituents at positions 1 and 2 have cis- or trans-relative stereochemistry; and the pharmaceutically acceptable salts, (1-6C)alkyl esters and (1-6C)alkanesulphonamides thereof. The compounds of formula I possess valuable pharmacological properties of use in medicines. The invention also concerns processes for the manufacture of, and pharmaceutical compositions containing a novel compound of formula I.
