Potent Neuroprotective Activity of Monoterpene Derived 4-[(3aR,7aS)- 1,3,3a,4,5,7a-Hexahydro-3,3,6-trimethylisobenzofuran-1-yl]-2-methoxyphenol in MPTP Mice Model

Studies of the neuroprotective activity of a series of monoterpene-derived compounds on the MPTP mice model showed that 4-[(3aR,7aS)-1,3,3a,4,5,7a-hexahydro-3,3,6-trimethylisobenzofuran-1-yl]-2-methoxyphenol 15 possessed a considerable neuroprotective activity. Compound 15 was synthesized by one-stage reaction of (+)-2-carene with vanillin. It has low acute toxicity and significantly decreased the development of catalepsy evoked by haloperidol in rats.
