Common Name

Teralin

Description

Teralin belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, teralin is considered to be a flavonoid lipid molecule. All of these products were reformulated in the late 1970s when methapyrilene was demonstrated to cause liver cancer in rats when given chronically. It has relatively strong sedative effects, to the extent that its primary use was as a medication for insomnia rather than for its antihistamine action. It also provided the sedative component of Excedrin PM. Methapyrilene is an antihistamine and anticholinergic of the pyridine chemical class which was developed in the early 1950s. Teralin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Together with scopolamine, it was the main ingredient in Sominex, Nytol, and Sleep-Eze. It was sold under the trade names Co-Pyronil and Histadyl EC. "Thionylan" redirects here. Teralin is found in Dalbergia parviflora and Thermopsis alterniflora. The thionyl halides should not be confused with "thionylan" and include thionyl fluoride, thionyl chloride, and thionyl bromide.
