COR167 is a CB2 agonist. It displayed potent immunomodulatory activity on immune cells from healthy subjects and patients with multiple sclerosis. It also showed protective effects on rat brain tissues toward ischemia and reperfusion-induced injury. COR167 has antinociceptive properties.

Tofenacin hydrochloride is an antidepressant drug with a tricyclic-like structure. It acts as a serotonin-norepinephrine reuptake inhibitor, and based on its close relation to orphenadrine, may also possess anticholinergic and antihistamine properties. Tofenacin is also the major active metabolite of orphenadrine and likely plays a role in its beneficial effects against depressive symptoms seen in Parkinson's disease patients.
