  Modulation of GABA_A-Receptors by Honokiol and Derivatives: Subtype Selectivity and Structure–Activity Relationship

  摘要：

  A series of 31 analogues of the neolignan honokiol (a major constituent of Magnolia officinalis) was synthesized, and their effects on GABA(A) receptors expressed in Xenopus oocytes were investigated. Honokiol enhanced chloride currents (I-GABA) through GABA(A) receptors of seven different subunit compositions with EC50 values ranging from 23.4 mu M (alpha(5)beta(2)) to 59.6 mu M (alpha(1)beta(3)). Honolciol was most efficient on alpha(3)beta(2) (maximal IGABA enhancement 2386%) > alpha(2)beta(2) (1130%) > alpha(1)beta(2) (1034%) > alpha(1)beta(1) (260%)). On alpha(1)beta(2)-receptors, N-substituted compounds were most active with 3-acetylamino-4'-O-methylhonolciol (31), enhancing I-GABA by 2601% (EC50 (alpha(1)beta(2)) = 3.8 mu M). Pharmacophore modeling gave a model with an overall classification accuracy of 91% showing three hydrophobic regions, one acceptor and one donor region. Unlike honokiol, 31 was most efficient on alpha(2)beta(2)- (5204%) > alpha(3)beta(2)- (3671%) > alpha(1)beta(2)-receptors (2601%), suggesting a role of the acetamido group in subunit-dependent receptor modulation.

  The cannabinoid CB2 receptor is known to modulate osteoclast function by poorly understood mechanisms. Here, we report that the natural biphenyl neolignan 4'-O-methylhonokiol (MH) is a CB2 receptor-selective antiosteoclastogenic lead structure (K-i < 50 nM). Intriguingly, MH triggers a simultaneous G(i) inverse agonist response and a strong CB2 receptor-dependent increase in intracellular calcium. The most active inverse agonists from a library of MH derivatives inhibited osteoclastogenesis in RANK ligand-stimulated RAW264.7 cells and primary human macrophages. Moreover, these ligands potently inhibited the osteoclastogenic action of endocannabinoids. Our data show that CB2 receptor-mediated cAMP formation, but not intracellular calcium, is crucially involved in the regulation of osteoclastogenesis, primarily by inhibiting macrophage chemotaxis and TNF-alpha expression. MH is an easily accessible CB2 receptor-selective scaffold that exhibits a novel type of functional heterogeneity.

  A set of ten derivatives of methylhonokiol, an anti-inflammatory active biphenyl-type neolignan from Magnolia grandiflora, has been evaluated for their in vitro cyclooxygenase-1/2 (COX-1/2) inhibitory activity using assays with purified prostaglandin H synthase (PGHS)-1 and PGHS-2 enzymes as well as for their 5-lipoxygenase (5-LOX) mediated LTB4 formation inhibitory activity using an assay with activated human polymorphonuclear leukocytes. The derivatization reactions included methylation, acetylation, hydrogenation, epoxydation and isomerization. Five of the derivatives are new to science. The most active compound against COX-1 and COX-2 was methylhonokiol with IC50 values of 0.1 mu M, whereas the most active compound against LTB4 formation was (E)-3'-propenyl-5-(2-propenyl)-biphenyl-2,4'-diol with an IC50 value of 1.0 mu M. Structure-activity relationship studies showed that the polarity of the derivatives plays a crucial role in their activity towards COX-1/2 enzyme and 5-LOX mediated LTB4 formation.
