Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name TEPRENONE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Teprenone

Teprenone is a terpene ketone in which a (9E,13E)-geranylgernayl group is bonded to one of the alpha-methyls of acetone (it is a mixture of 5E- and 5Z-geoisomers in a 3:2 ratio). It has a role as an anti-ulcer drug, a hepatoprotective agent, a neuroprotective agent, a nephroprotective agent, a cardioprotective agent and a Hsp70 inducer. It is a terpene ketone and a methyl ketone. It contains a geranylgeranyl group. — ChEBI
