生物活性: Imidazole is a planar 5-membered ring. Imidazole is a highly polar compound. Imidazole has been used extensively as a corrosion inhibitor. Imidazole is incorporated into many important biological molecules. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Imidazole is useful as a buffer in the pH range of 6.2-7.8 One of the applications of imidazole is in the purification of His-tagged proteins in immobilised metal affinity chromatography(IMAC). Imidazole is used to elute tagged proteins bound to Ni ions attached to the surface of beads in the chromatography column. An excess of imidazole is passed through the column, which displaces the His-tag from nickel co-ordination, freeing the His-tagged proteins. Imidazole has become an important part of many pharmaceuticals. Synthetic imidazoles are present in many fungicides and antifungal, antiprotozoal, and antihypertensive medications. Imidazole is part of the theophylline molecule, found in tea leaves and coffee beans, which stimulates the central nervous system. It is present in the anticancer medication mercaptopurine, which combats leukemia by interfering with DNA activities.

生物活性: Acetylcholinesterase (ACHE; EC 3.1.1.7) is a cholinergic enzyme mainly found in neuromuscular junctions and cholinergic type chemical synapses, and is often used in biochemical research. Acetylcholinesterase catalyzes the breakdown or hydrolysis of acetylcholine and some other choline esters that act as neurotransmitters into acetate and choline. Acetylcholinesterase's main role is to terminate neuronal transmission and signaling between synapses to prevent ACh spread and activation of nearby receptors.

生物活性: Tetrazolium Red(2,3,5-Triphenyltetrazolium chloride; TPTZ) is used to visualize dehydrogenase enzyme activity; initially the tetrazolium solution is colorless but changes to red when it comes into contact with hydrogen. Tetrazolium red is used in a biochemical viability test for seeds. The test relies on dehydrogenase enzymes to release hydrogen ions which subsequently reduce the colorless tetrazolium salt solution to a red compound called formazan. Living cells turn red while dead cells remain colorless.
