Imidazole-15N2 (Glyoxaline-15N2) is 15N labeled Imidazole. Imidazole (Glyoxaline, 1,3-Diaza-2,4-cyclopentadiene) is a heterocyclic aromatic compound. Imidazole bearing molecules have been used as corrosion, acetylcholinesterase (AChEI) and xanthine oxidase (XO) inhibitors, performing biological activities such as antifungal, antituberculosis, anti-inflammatory, antioxidant, and analgesic, amongst many others. Imidazole inhibits the enzymatic conversion of the endoperoxides (PGG2 and PGH2) to thromboxane A2 by platelet microsomes. Imidazole derivatives exhibits inhibition on SARS-CoV-2 3CLPro enzyme, which is promising for research in the field of Alzheimers disease, gout, COVID-19 and thrombo-embolic disease[1][2][3][4].
