Description
Curator's Comment: Description was created based on several sources, including https://www.hindawi.com/journals/jchem/2013/329412/ | http://www.inchem.org/documents/sids/sids/288324.pdf

Imidazole is a planer five-member heterocyclic ring with 3C and 2N atom and in ring N is present in 1st and 3rd positions. The imidazole ring is a constituent of several important natural products, including purine, histamine, histidine and nucleic acid. Being a polar and ionisable aromatic compound, it improves pharmacokinetic characteristics of lead molecules and thus used as a remedy to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules. The imidazole derivatives possess extensive spectrum of biological activities such as antibacterial, anticancer, antitubercular, antifungal, analgesic, and anti-HIV activities. The organic compound is used in the chemical industry as an intermediate in the production of pharmaceuticals, pesticides, dye intermediates, auxiliaries for textile dyeing and finishing, photographic chemicals and corrosion inhibitors. The chemical possesses properties (corrosivity to skin, irreversible damage to eyes, teratogenic effects) indicating a hazard for human health. Humans are exposed by consumer products (chemical concentrations up to 10%) and at the workplace. Therefore, the chemical is a candidate for further work. An exposure assessment and if indicated a risk assessment is recommended.

Curator's Comment: Imidazole was first synthesized by Heinrich Debus in 1858, but various imidazole derivatives had been discovered as early as the 1840s. reference retrieved from https://www.hindawi.com/journals/jchem/2013/329412/

Sample Use Guides

The pharmacokinetic parameters were determined in human studies with ITF 182 in single (248 mg of imidazole) and multiple dose (3 single doses per day) studies. The main pharmacokinetic parameters in humans after oral intake may be summarized as follows: maximum plasma levels were reached after approx. 3 hours, elimination half-life was approx. 1.8 to 3 hours. Bioavailability was complete. Protein binding was determined to range between 5 to 15 %. In contrast, no effects were noted in a pilot study after dermal application Imidazole is of moderate oral toxicity in a scientifically valid study. LD50 in rats was determined to be 960 - 970 mg/kg bw.
Route of Administration: Oral
Imidazole did not exhibit cytotoxic effects on B16 cells at a concentration below 100 uM. Imidazole inhibits B16 cell migration through beta-catenin degradation.
