Abstract
Honokiol (HNK) is a typical natural biphenyl polyphenol compound. It has been proven to have a wide range of biological activities, including pharmacological effects such as anti-cancer, anti-inflammatory, neuroprotective, and antimicrobial. However, due to the poor stability, water solubility, and bioavailability of HNK, HNK has not been used in clinical treatment. This article reviews the latest research on the pharmacological activity of HNK and summarizes the HNK derivatives designed and improved by several researchers. Reviewing these contents could promote the research process of HNK and guide the design of better HNK derivatives for clinical application in the future.

Abstract
Honokiol is a natural bioactive neolignan and has been widely researched and structural modified as an anticancer agent. In this paper, 18 honokiol derivatives were synthesized and investigated for their antitumor activity. Among these, the promising compound 5a exhibited much higher anti-proliferative activity with IC50 value of 10.41 μM. Transwell assays showed that 5a could significantly inhibit the invasion and migration of I-10 cells at 2.5 μM, which was further confirmed by the western blotting experiments with down-regulation of the HIF-1α and its associated downstream proteins MMP-2 and MMP-9. Overall, these results provided useful suggestion for further structural optimization of honokiol derivatives.

Abstract
As a known natural product with anti-tumor activity, honokiol has been widely researched and structural modified. Lots of honokiol derivatives have been found to possess good anti-proliferative activity and showed great potential in cancer therapy, but the SAR (structure-activity relationship) was still confused. Here in, the SAR were comprehensively researched by summary of reported derivatives and synthesis of novel derivatives. Amongst novel derivatives, the promising compounds A6 and A10 exhibited potent and selective anti-proliferative activities against K562 cell line with the IC50 values of 5.04 and 7.08 μM respectively. The SAR was discussed around honokiol and 79 derivatives by the means of CoMFA and theoretical calculation, which provided useful suggestion for further structural optimization of honokiol derivatives.

Abstract
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 neolignans honokiol and magnolol are the main constituents of Magnolia bark extracts. In the central nervous system, Magnolia bark preparations that contain honokiol are thought to primarily interact with γ-aminobutyric acid A (GABAA) receptors. However, stress responses inherently involve the noradrenergic system, which has not been investigated in the pharmacological mechanism of honokiol. We present here interactions of honokiol and other synthesized biphenyl-type neolignans and diphenylmethane analogs with the norepinephrine transporter (NET), which is responsible for the synaptic clearance of norepinephrine and the target of many anxiolytics. Of the synthesized compounds, 16 are new chemical entities, which are fully characterized. The 52 compounds tested show mild, non-potent interactions with NET (IC50 > 100 µM). It is thus likely that the observed anxiolytic effects of, e.g., Magnolia preparations, are not due to direct interaction with the noradrenergic system.

Abstract
The present study aimed to investigate the protective effects of magnolol on acute 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis, and its underlying mechanisms. Experimental colitis was induced by intracolonic administration of TNBS/ethanol into rats. The model rats were randomly assigned into groups: TNBS, magnolol (high, medium and low doses), and salazosulfapyridine (positive control). All intervention regimens were administered by oral gavage, once a day for 7 consecutive days, 24 h after colitis induction. Histological and biochemical changes in colonic inflammation were evaluated by hematoxylin and eosin and immunohistochemistry, respectively. Rats treated with all doses of magnolol exhibited decreased colonic myeloperoxidase activity (P<0.05 vs. TNBS), reduced serum levels of proinflammatory cytokines [including interleukin (IL)-6 and IL-17], and downregulated Toll-like receptor-4 (TLR-4) mRNA expression. Histological analysis revealed that medium and high doses of magnolol conferred an anti-inflammatory effect, which was indicated by a decrease in disease activity index, an increase in thymus index, and downregulation of nuclear factor (NF)-κB p65 mRNA and TLR-4 protein expression. However, only high-dose magnolol significantly ameliorated the elevated colon weight/length ratio. The results of the present study indicate that magnolol exerts protective effects against acute TNBS-induced colitis in rats, and the TLR-4/NF-κB signaling pathway-mediated inhibitory effect on inflammatory cascades may contribute to the protective activity of magnolol.

Inhibitory effects of magnolol and honokiol on human calcitonin aggregation. Sci Rep 2015; 5:13556.

Abstract
Amyloid formation is associated with multiple amyloidosis diseases. Human calcitonin (hCT) is a typical amyloidogenic peptide, its aggregation is associated with medullary carcinoma of the thyroid (MTC), and also limits its clinical application. Magnolia officinalis is a traditional Chinese herbal medicine; its two major polyphenol components, magnolol (Mag) and honokiol (Hon), have displayed multiple functions. Polyphenols like flavonoids and their derivatives have been extensively studied as amyloid inhibitors. However, the anti-amyloidogenic property of a biphenyl backbone containing polyphenols such as Mag and Hon has not been reported. In this study, these two compounds were tested for their effects on hCT aggregation. We found that Mag and Hon both inhibited the amyloid formation of hCT, whereas Mag showed a stronger inhibitory effect; moreover, they both dose-dependently disassembled preformed hCT aggregates. Further immuno-dot blot and dynamic light scattering studies suggested Mag and Hon suppressed the aggregation of hCT both at the oligomerization and the fibrillation stages, while MTT-based and dye-leakage assays demonstrated that Mag and Hon effectively reduced cytotoxicity caused by hCT aggregates. Furthermore, isothermal titration calorimetry indicated Mag and Hon both interact with hCT. Together, our study suggested a potential anti-amyloidogenic property of these two compounds and their structure related derivatives.

Abstract
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 GABAA 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 α1β2γ2S GABAA receptors. The strongest IGABA enhancement was induced by compound 5 (3-acetamido-4'-ethoxy-3',5-dipropylbiphenyl-2-ol, Emax: 123.4±9.4% of IGABA-max) and 6 (5'-amino-2-ethoxy-3',5-dipropylbiphenyl-4'-ol, Emax: 117.7±13.5% of IGABA-max). Compound 5 displayed, however, a significantly higher potency (EC50=1.8±1.1 μM) than compound 6 (EC50=20.4±4.3 μM). 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 μM; 7: EC50=33.2±5.1 μM) than the full agonist GABA.

Abstract
OBJECTIVE Gastric carcinoma is a malignant tumor that responds poorly to both chemotherapy and radiation therapy. In our study, we investigated the anti-cancer effect of honokiol, an active component isolated and purified from the Magnolia officinalis, in human gastric carcinoma MGC-803 cell line. METHODS The cell viability was detected by the CCK8 assay. The cell apoptosis and cell cycle arrest were assessed by flow cytometer. The protein expression of cell cycle regulators and tumor suppressors were analyzed by western blotting. RESULTS Treatment of human gastric carcinoma cells with honokiol induced cell death in a dose-and time-dependent manner by using CCK8 assay. Consistent with the CCK8 assay, the flow cytometry results showed that the proportion of apoptosis cells had gained when the cells were exposed to honokiol. Moreover, Cyclin B1, CDC2 and cdc25C were downregulated, and the expression of p-CDC2 and p-cdc25c was significantly upregulated upon honokiol treatment. P53 and p21 were significantly upregulated by honokiol treatment. Treatment of MGC-803 cells with honokiol significantly increased the pro-apoptotic Bax level and decreased the anti-apoptotic Bcl-2 level. CONCLUSIONS These results confirmed that honokiol could induce apoptosis and cell cycle arrest, the underlying molecular mechanisms, at least partially, through activation p53 signaling and downregulation CDC2/cdc25C expression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Magnolia officinalis is one of the commonly used in traditional Chinese medicine for the treatment of fever, chronic bronchitis and stomach ailments. Magnolol and honokiol are isomers with hydroxylated biphenol compound in the extract of Magnolia officinalis. This study aims to determine the isomers in rat plasma and evaluate their pharmacokinetic pattern after administration emulsion. MATERIALS AND METHODS Sprague Dawley male rats received either an intravenous (i.v.25, mg/kg) or oral (50mg/kg) dose of the emulsion of the isomer. A sensitive and specific ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) method was developed for the investigation of the pharmacokinetics of magnolol and honokiol in rats. Kaempferol was employed as an internal standard. RESULTS The plasma samples were deproteinized with acetonitrile, the post-treatment samples were analyzed on an Agela C18 column interfaced with a triple quadrupole tandem mass spectrometer in negative electrospray ionization mode. Acetonitrile and 5 mmol/L ammonium acetate buffer solution (65: 35, v/v) was used as the mobile phase at a flow rate of 0.2 mL/min. Following oral administration of emulsion to rats, magnolol attained mean peak plasma concentrations of 426.4 ± 273.8 ng/mL at 1.20 h, whereas honokiol reached peak plasma concentrations of 40.3 ± 30.8 ng/mL at 0.45 h. The absolute bioavailability of magnolol and honokiol is 17.5 ± 9.7% and 5.3 ± 11.7%. By comparison, the AUC0-∞ of magnolol was 5.4 times higher than that of honokiol after intravenous administration, but AUC0-∞ of magnolol was about 18-fold higher than honokiol after oral administration.
