4-O-Methylhonokiol is aneolignan, a type ofphenolic compound. It isfound in the bark ofMagnolia grandiflora[1] and inM. virginiana flowers.[2]
4-O-Methylhonokiol is aCB2 receptor ligand (Ki = 50 nM), showinginverse agonism andpartial agonism via different pathways (cAMP and Ca2+), which potently inhibits osteoclastogenesis.[3] 4-O-Methylhonokiol further attenuates memory impairment inpresenilin 2 mutant mice through reduction of oxidative damage and inactivation ofastrocytes and the ERK pathway.[4] The different neuroprotective effects reported inrodent models may be mediated via CB2 receptors.[5] 4-O-Methylhonokiol activates CB2 receptors and also inhibits the oxygenation of the major endocannabinoid2-AG viaCOX-2 in a substrate-selective manner, thus leading to potential synergistic effects at CB receptors.[6] The same study also provided data that 4-O-methylhonokiol can readily pass the blood–brain barrier.
