Cannabis Compound Identification
Common NameBetazole
DescriptionBetazole, also known as histalog or 96791, belongs to the class of organic compounds known as 2-arylethylamines. These are primary amines that have the general formula RCCNH2, where R is an organic group. Betazole is a histamine H2 agonist, which is used clinically to test gastric secretory function. Gastritis can be diagnosed given late absence of gastric acid which is unresponsive to betazole stimulation. In humans, betazole is involved in betazole action pathway. Betazole can be used as a gastric secretory stimulant instead of histamine with the advantage of not provoking side effects and thus not requiring the use of antihistaminic compounds. Betazole is only found in individuals that have used or taken this drug. Surprisingly, betazole has also been detected in the volatile fraction of Cannabis sativa samples obtained from police seizures (PMID: 26657499 ).

Enzymes

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
The H2 subclass of histamine receptors mediates gastric acid secretion. Also appears to regulate gastrointestinal motility and intestinal secretion. Possible role in regulating cell growth and differentiation. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and, through a separate G protein-dependent mechanism, the phosphoinositide/protein kinase (PKC) signaling pathway
