Magnolol is an organic compound that is classified as lignan. It is a bioactive compound found in the bark of the Houpu magnolia (Magnolia officinalis) and in M. grandiflora.[2]
Magnolol is a compound that acts on GABA_A receptors and functions as an allosteric modulator. It has antifungal properties and demonstrates anti-periodontal disease effects in animal models. In cell cultures, magnolol stimulates osteoblasts and inhibits osteoclasts, indicating potential for anti-osteoporosis treatment. It also binds in a dimeric form to PPARγ, acting as an agonist of this nuclear receptor. Additionally, magnolol may interact with cannabinoid receptors, acting as a partial agonist of CB2 receptors with lower affinity for CB1 receptors.
Bioactivity
It is known to act on the GABAA receptors in rat cells in vitro[3] as well as having antifungal properties.[4] Magnolol has a number of osteoblast-stimulating and osteoclast-inhibiting activities in cell culture and has been suggested as a candidate for screening for anti-osteoporosis activity.[5] It has anti-periodontal disease activity in a rat model.[6] Structural analogues have been studied and found to be strong allosteric modulators of GABAA.[7]
Magnolol is also binding in dimeric mode to PPARγ, acting as an agonist of this nuclear receptor.[8]
Magnolol may interact with cannabinoid receptors, acting as a partial agonist of CB2 receptors, with lower affinity for the CB1 receptor.[9]
