Natural product reports, 28(6), 1143-1191 (2011-04-08)
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
UV excitation and radiationless deactivation of imidazole.
