Imidazole derivatives of general formula (I) and pharmacologically acceptable salts thereof, wherein m and n are each an integer of 1 to 3, R' is hydrogen or ester residue, and the indoline skeleton may be substituted by at least one member selected from a C, to C10 alkyl group and a C1 to C15 alkoxy group. These compounds have excellent pharmacological actions such as inhibition of lipid peroxide formation, inhibition of platelet agglutination caused by thromboxane A2 synthetase inhibition, and vasodilation. Thus they are effectively used in preventing or treating asthma, thrombosis, embolism, arteriosclerosis, hypertension, hyperlipemia, cerebral apoplexy, cardiac infarction, dementia, diabetes, etc.
of rat brain homogenate and on arachidonate-induced TXA2-dependent aggregation of rabbit platelets. The anti-platelet and anti-peroxidative activities were related to the lipophilicity of the 5-substituent. The 5-hexyloxy derivative (13) showed about 35-fold higher inhibitory activity on TXA2 synthesis than that of ozagrel and about 100-fold higher activity on lipid peroxidation than that of alpha-tocopherol
