| Description | Tetrabenazine, also known as nitoman or xenazine, belongs to the class of organic compounds known as tetrahydroisoquinolines. These are tetrahydrogenated isoquinoline derivatives. Tetrabenazine is a very strong basic compound (based on its pKa). A benzoquinolizine that is 1,2,3,4,4a,9,10,10a-octahydrophenanthrene in which the carbon at position 10a is replaced by a nitrogen and which is substituted by an isobutyl group at position 2, an oxo group at position 3, and methoxy groups at positions 6 and 7. |
