General description
Imidazole is a five-membered heterocycle that is found in many naturally occurring compounds. It exhibits both acidic and basic properties. It is reported to be an inhibitor of thromboxane formation. Its vertical spectrum and the radiationless decay have been recorded and analyzed.
Application
Excellent for buffers in the range of pH 6.2-7.8

A great number of structurally diverse natural products containing five-membered heterocyclic subunits, such as imidazole, oxazole, thiazole, and their saturated congeners, are abundant in nature. These naturally occurring metabolites often exhibit extensive and pharmacologically important biological activities. The latest progress

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
