The imidazole derivatives of the general formula: ##STR1## wherein R.sup.1 represents a hydrogen atom, or a straight- or branched-chain alkyl group containing from 1 to 12 carbon atoms, the symbol .dbd. represents a double bond that bond is E or Z, or a triple bond, and m and n, which may be the same or different, each represent zero, or an integer of 1 to 10, and non-toxic acid addition salts thereof, and, when R.sup.1 represents a hydrogen atom, non-toxic salts thereof are new compounds. These compounds have a strong inhibitory effect on thromboxane synthetase from rabbit platelet microsomes, and are useful as therapeutically active agents for inflammation, hypertension, thrombus, cerebral apoplexy and asthma.
structure--activity relationships of imidazolederivatives as inhibitors of thromboxane (TX) synthetase were investigated. Introduction of various substituents (e.g., one or two methyl groups, a halogen atom, a methylidene group, unsaturated bonds, or a phenylene group) into the alpha position or other positions in the carboxy-bearing side chain of 1-(7-carboxyheptyl)imidazole (15) was found to increase the
