Imidazole derivatives have antibacterial, anticancer, antitubercular, antifungal, and analgesic properties [ 22, 23 ]. Benzothiazole and its related heterocycle benzoxazole are other versatile scaffolds in organic chemistry [ 24, 25 ].
Imidazole-based histidine compounds play a very important role in intracellular buffering. Histidine can be decarboxylated to histamine. Histamine can cause urticaria (hives) when it is produced during allergic reaction. Imidazole substituents are found in many pharmaceuticals. Visa mer Imidazole (ImH) is an organic compound with the formula C3N2H4. It is a white or colourless solid that is soluble in water, producing a mildly alkaline solution.
