  Bioinspired Honokiol Analogs and Their Evaluation for Activity on the Norepinephrine Transporter

  摘要：

  在传统的亚洲药物系统中，玉兰属植物的根和茎皮制剂被广泛用于治疗焦虑和其他神经紊乱。双苯型新木兰醇和木兰醇是玉兰树皮提取物的主要成分。在中枢神经系统中，含有新木兰醇的玉兰树皮制剂被认为主要与γ-氨基丁酸A（GABAA）受体相互作用。然而，应激反应本质上涉及未在新木兰醇的药理机制中进行研究的去甲肾上腺素系统。我们在这里介绍了新木兰醇和其他合成的双苯型新木兰醇和二苯甲烷类似物与去甲肾上腺素转运蛋白（NET）的相互作用，该蛋白负责去甲肾上腺素的突触清除，是许多抗焦虑药物的靶点。在合成的化合物中，有16种是新的化学实体，已经完全表征。测试的52种化合物与NET显示出轻微、非强效的相互作用（IC50 > 100 µM）。因此，例如玉兰制剂的观察到的抗焦虑效果可能不是由于与去甲肾上腺素系统的直接相互作用。

  Nitrogenated honokiol derivatives allosterically modulate GABAA receptors and act as strong partial agonists

  摘要：

  In traditional Asian medicinal systems, preparations of the root and stem bark of Magnolia species are widely used to treat anxiety and other nervous disturbances. The biphenyl-type neolignan honokiol together with its isomer magnolol are the main constituents of Magnolia bark extracts. We have previously identified a nitrogen-containing honokiol derivative (3-acetylamino-4'-O-methylhonokiol, AMH) as a high efficient modulator of GABA(A) receptors. Here we further elucidate the structure-activity relation of a series of nitrogenated biphenyl-neolignan derivatives by analysing allosteric modulation and agonistic effects on alpha(1)beta(2)gamma(2S) GABA(A) receptors. The strongest I-GABA enhancement was induced by compound 5 (3-acetamido-4'-ethoxy-3',5-dipropylbiphenyl-2-ol, E-max: 123.4 +/- 9.4% of IGABA-max) and 6 (5'-amino-2-ethoxy-3',5-dipropylbiphenyl-4'-ol, E-max: 117.7 +/- 13.5% of IGABA-max). Compound 5 displayed, however, a significantly higher potency (EC50 = 1.8 +/- 1.1 mu M) than compound 6 (EC50 = 20.4 +/- 4.3 mu M). Honokiol, AMH and four of the derivatives induced significant inward currents in the absence of GABA. Strong partial agonists were honokiol (inducing 78 +/- 6% of IGABA-max), AMH (63 +/- 6%), 5'-amino-2-O-methylhonokiol (1) (59 +/- 1%) and 2-methoxy-5'-nitro-3',5-dipropylbiphenyl-4'-ol (3) (52 +/- 1%). 3-N-Acetylamino-4'-ethoxy-3',5-dipropyl-biphenyl-4'-ol (5) and 3-amino-4'-ethoxy-3',5-dipropyl-biphenyl-4'-ol (7) were less efficacious but even more potent (5: EC50 = 6.9 +/- 1.0 mu M; 7: EC50 = 33.2 +/- 5.1 mu M) than the full agonist GABA.

  promising anti-inflammatory activity for the treatment of various diseases. There are many efforts on the synthesis and structure-activity relationship of honokiol derivatives. However, regioselective O-alkylation of honokiol remains a challenge and serves as a tool to provide not only some derivatives but also chemical probes for target identification and mode of action. In this study, we examined the reaction

  Honokiol, widely known as an antitumor agent, has been used as an antiangiogenesis drug lead. In this paper, 47 honokiol analogues and derivatives were investigated for their antiangiogenic activity by application of the transgenic zebrafish screening model, antiproliferative and cytotoxic activity against HUVECs, and three tumor cell lines by MTT assay. 3',5-Diallyl-2, 4'-dihydroxy-[1,1'-biphen-yl]-3,5'-dicarbaldehyde (8c) was found to suppress the newly grown segmental vessels from the dorsal aorta of zebrafish and prevent inappropriate vascularization as well as exhibit more potent inhibitory effects on the proliferation of HUVECs, A549, HepG2, and LL/2 cells (IC50 = 15.1, 30.2, 10.7, and 21.7 mu M, respectively) than honokiol (IC50 = 52.6, 35.0, 16.5, and 65.4 mu M, respectively). Analogue 8c also effectively inhibited the migration and capillary-like tube formation of HUVECs in vitro. The antiangiogenic effect and antiproliferative activity of these structurally modified honokiol analogues and derivatives have led to the establishment of a structure-activity relationship.

  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.
