Rac-endo-borneol

Rac-endo-borneol is a bicyclic monoterpene with potential antinociceptive and anti-inflammatory properties. It enhances blood-brain barrier (BBB) permeability by inhibiting efflux proteins and modulating tight junctions, thereby improving drug delivery to the brain. Its effects are reversible and transient, associated with increased vasodilatory neurotransmitters.
