  • Title: Imidazole: a selective inhibitor of thromboxane synthetase.
    Author: Moncada S, Bunting S, Mullane K, Thorogood P, Vane JR, Raz A, Needleman P.
    Journal: Prostaglandins; 1977 Apr; 13(4):611-8. PubMed ID: 558637.
    Abstract:
    Imidazole inhibits the enzymic conversion of the endoperoxides (PGG2 and PGH2) to thromboxane A2 by platelet microsomes (IC50: 22 MICRONG/ML; DETERMINED BY BIOASSAY). The inhibitor is selective, for prostaglandin cyclo-oxygenase is only affected at high doses. Radiochemical data confirms that imidazole blocks the formation of 14C-thromboxane B2 from 14C-PGH2. Several imidazole analogues and other substances were tested but only 1-methyl-imidazole was more potent than imidazole itself. The use of imidazole to inhibit thromboxane formation could help to elucidate the role of thromboxanes in physiology or pathophysiology.
