Novel compounds, compositions and pharmaceutical a method of inhibiting the 5-lipoxygenase pathway in an animal in need thereof which comprising administering an effective, 5-lipoxygenase pathway inhibiting amount of a 4,5-diaryl-2(substituted)-imidazole or a pharmaceutically acceptable salt thereof.
Diphenylimidazole and diphenylthiazole derivatives were synthesized and tested as inhibitors of platelet aggregation in in vitro experiments with the rabbit. Diphenylthiazole derivatives (10) were more potent than diphenylimidazole derivatives (4) in inhibiting arachidonic acid-induced platelet aggregation of rabbit platelet-rich plasma. Two diphenylimidazole and eight diphenylthiazole derivatives were evaluated for ex vivo arachidonic acid and collagen-induced platelet aggregation inhibitory activity using guinea pigs. In these compounds, 4, 5-bis(4-methoxyphenyl)-2-(1, 5-dimethyl-2-pyrrolyl)thiazole (10n) showed strong activity in vitro and ex vivo. The ex vivo activity of 10n was 200 times stronger than that of aspirin. The mechanism of the activity of 10n was the inhibition of cyclo-oxygenase.
