Abstract
Periodontitis is a common chronic inflammatory disease driven by the interaction between a dysbiotic oral microbiome and the dysregulated host immune-inflammatory response. Naturally derived nutraceuticals, such as resveratrol and its analogs, are potential adjunctive therapies in periodontal treatment due to their antimicrobial and anti-inflammatory properties. Furthermore, different analogs of resveratrol and the choice of solvents used may lead to varying effects on therapeutic properties. This review presents the current findings and gaps in our understanding on the potential utility of resveratrol and its analogs in periodontal treatment.

Tetramethoxystilbene-Loaded Liposomes Restore Reactive-Oxygen-Species-Mediated Attenuation of Dilator Responses in Rat Aortic Vessels Ex vivo. Molecules 2019; 24:molecules24234360. [PMID: 31795324 PMCID: PMC6930636 DOI: 10.3390/molecules24234360] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2019] [Revised: 11/25/2019] [Accepted: 11/27/2019] [Indexed: 01/08/2023] Open
Abstract
The methylated analogue of the polyphenol resveratrol (RV), 2,3′,4,5′-tetramethoxystilbene (TMS) displays potent antioxidant properties and is an effective cytochrome P450 (CYP) 1B1 inhibitor. The bioavailability of TMS is low. Therefore, the use of liposomes for the encapsulation of TMS is a promising delivery modality for enhanced uptake into tissues. We examined the effect of delivery of TMS in liposomes on the restoration of vasodilator responses of isolated aortic vessels after acute tension elevation ex vivo. Aortic vessels from young male Wistar rats were isolated, and endothelial-dependent (acetylcholine, ACh) and -independent (sodium nitroprusside, SNP) responses assessed. Acute tension elevation (1 h) significantly reduced ACh dilator responses, which were restored following incubation with superoxide dismutase or apocynin (an NADPH oxidase inhibitor). Incubation with TMS-loaded liposomes (mean diameter 157 ± 6 nm; PDI 0.097) significantly improved the attenuated dilator responses following tension elevation, which was sustained over a longer period (4 h) when compared to TMS solution. Endothelial denudation or co-incubation with L-NNA (Nω-nitro-l-arginine; nitric oxide synthase inhibitor) resulted in loss of dilator function. Our findings suggest that TMS-loaded liposomes can restore attenuated endothelial-dependent dilator responses induced by an oxidative environment by reducing NADPH-oxidase-derived ROS and potentiating the release of the vasodilator nitric oxide. TMS-loaded liposomes may be a promising therapeutic strategy to restore vasodilator function in vascular disease.

Abstract
The aim of this study is to establish a rapid and sensitive method for detecting lentinan (LNT) in biosamples and to evaluate the pharmacokinetics of LNT in mice and rats. A diethylenetriaminepentaacetic acid (DTPA) derivative of LNT (DTPA-LNT) was synthesized first to allow labelling with 99m-technetium (99mTc). After purification and identification, 99mTc-DTPA-LNT was intravenously administered to mice (2 mg kg-1) and rats at different doses (0.5, 2 and 8 mg kg-1). The results showed that the 99mTc-labelling method was suitable for the quantification of the LNT concentration in biological samples, with satisfactory linearity (r2 > 0.998), precision (<7%), accuracy (95.01-104.51%) and total recovery (∼90%). The blood concentration-time profiles of 99mTc-DTPA-LNT were consistent with the two-compartment model and showed a rapid distribution phase and a slow elimination, and no significant difference in the blood level of LNT was found among the tested doses (0.5, 2 and 8 mg kg-1). LNT was predominantly incorporated into the liver and spleen, and there was a small amount of aggregation in the bile, kidneys, lungs and stomach. Approximately 40% of the administered radioactivity was detected in urine and faeces within 24 h post-dosing. In addition, SPECT imaging of 99mTc-DTPA-LNT was performed to visually reveal the pharmacokinetic characteristics of LNT. These findings provide a reference for further study and for use of LNT and other β-glucans.

Abstract
Stilbenes are a large group of compounds with the C6 C2 C6 skeleton, in which two aromatic rings are connected by an ethylene bridge. Resveratrol and its structural analog, pterostilbene, are by far the two most widely researched stilbenes in terms of their beneficial bioactivities. However, the bioefficacy of these compounds is greatly reduced when consumed orally due to their poor aqueous solubility, which leads to poor bioavailability. To overcome the limitation, strategies improving their solubility, absorption, and systemic concentration were applied when designing a suitable edible delivery system. This review will summarize the findings from the studies evaluating the oral bioavailability of stilbenes with emphasize on the resveratrol and pterostilbene. It will also include the edible delivery systems currently available and their effect on the oral bioavailability. © 2018 BioFactors, 44(1):5-15, 2018.

Abstract
The synthetic resveratrol analogue DMU-212 (3,4,4',5-tetramethoxystilbene) has been shown to possess stronger anticancer activity than resveratrol in a variety of tumour cells. To date, there has been no appropriate procedure that would ensure a reliable data about levels of metabolic products of DMU-212 in cancer cell lines. The purpose of this study was to develop a new procedure for determination of DMU-212 and its three metabolites (DMU-214, DMU-281, DMU-291) in cell lines. Analyses were performed using an HPLC system coupled with a triple quadrupole mass spectrometer operating in multiple reaction monitoring mode. Separation was conducted using a C18 column at a flow rate 800μL/min with a mobile phase consisting of 5mM ammonium acetate with 0.1% formic acid (solvent A) and acetonitrile (solvent B). The new methodology is fast, simple and has excellent specificity. Moreover, it showed good linearity in two matrices - cell lysates and culture media. Accuracy values for analytes evaluated at different concentration levels ranged from 0.43 to 18% (%bias). The intra-day and inter-day precision, expressed as CV, was in a range 0.49-5.5% and 0.83-13%, respectively. The validated procedure was successfully applied to quantify the resveratrol analogues in the human ovarian cancer cell line SKOV3.

Abstract
Oxyresveratrol is a major active compound in the heartwood of Artocarpus lacucha. It plays an important role in anti-tyrosinase, antioxidant, anti-inflammatory, antiviral and neuroprotective properties. There are many A. lacucha commercial products available on the market for skin whitening and anti-aging effects. To evaluate the quality of raw material from the plant, a monoclonal antibody (MAb) against oxyresveratrol was generated in this study. The immunogen was prepared by the Mannich reaction for the conjugation of oxyresveratrol and cationized bovine serum albumin (cBSA). The conjugation of oxyresveratrol-cBSA at a ratio of 1:50 was used for the immunization. The novel MAb (E4) was specific to oxyresveratrol and resveratrol. An indirect competitive enzyme-linked immunosorbent assay (ELISA) using the MAb (E4) was developed for the determination of oxyresveratrol. The linear range for the measurement of oxyresveratrol was 63-500 ng/mL and the precision (% relative standard deviation) was found to be <10% with the percentages of recovery from 95.93-103.55%. According to the validation analysis, the established ELISA can be applied for the determination of oxyresvertrol in the heartwood of A. lacucha and samples of the traditional drug Puag-Haad. With reliability and high sensitivity, this assay can provide an alternative approach for the quantitative analysis of oxyresveratrol in A. lacucha samples.

Abstract
Most plant polysaccharides cannot be digested and utilized by host enzymes, and must be subjected to microbial fermentation before being assimilated by the host. MDG-1, a water-soluble β-d-fructan extracted from the roots of Ophiopogon japonicus, has potent anti-obesity and hypoglycemic effects. Interestingly, we found that MDG-1 is hardly absorbed into the blood. We presumed that MDG-1 might exhibit its potent efficacy via regulating the gut microbiota of the host. However, the overall microbiota structure variation of obese mice treated with MDG-1 and the direct metabolic consequences of MDG-1 on specific microbiota phyla remain poorly understood. Here, obese male C57BL/6 mice induced by a high-fat diet were given either vehicle or MDG-1 at a dose of 300mg/kg for 12 weeks and the overall fecal gut microbiota structure change was analyzed via pyrosequencing. On this basis, we further separated and identified the dominant bacteria of the feces from the MDG-1 treated mice. These bacteria were then cultured with MDG-1 in vitro and their metabolic profiles were analyzed via a metabonomic approach. The results showed that MDG-1 could decrease the ratio of Firmicutes/Bacteroidetes, adjust the abnormal gut microbiota to the normal state and alter their metabolic profiles. In addition, we identified that the indigestible MDG-1 could be degraded and utilized by gut microbiota that could, in turn, be assimilated and used by the host, where it exerted weight loss effects, energy metabolism promotion and boosted the immune system effectiveness.

Abstract
trans-2,3-Dimethoxystilbene (2,3-DMS) and trans-3,4-dimethoxystilbene (3,4-DMS) are two synthetic resveratrol (trans-3,5,4'-trihydroxystilbene) analogs. In this study, a simple HPLC method was developed and validated to determine 2,3-DMS and 3,4-DMS in rat plasma. Chromatographic separation was obtained with a reversed-phase HPLC column through a 12.5-min gradient delivery of a mixture of acetonitrile and water at the flow rate of 1.5 mL/min at 50 °C. The lower limit of quantification was 10 ng/mL. After successful validation, the pharmacokinetic profiles of 2,3-DMS and 3,4-DMS were subsequently studied in Sprague-Dawley rats. Upon single intravenous administration (4 mg/kg), 2,3-DMS had a medium volume of distribution of the central compartment (Vc = 2.71 ± 0.51 L/kg), quite rapid clearance (Cl = 52.0 ± 7.0 mL/min/kg), moderate mean transit time (MTT0→last = 131.0 ± 4.5 min) but a fairly long terminal elimination half-life (t1/2λZ = 288.9 ± 92.9 min). Interestingly, 3,4-DMS displayed a pharmacokinetic profile apparently distinct from 2,3-DMS and it had more extensive distribution (Vc = 5.58 ± 1.73 L/kg), faster clearance (Cl = 143.4 ± 40.5 mL/min/kg) and shorter residence (MTT0→last = 61.4 ± 27.1 min). Following single oral administration (10 mg/kg), 2,3-DMS had low and erratic plasma exposure (Cmax = 37.5 ± 23.7 ng/mL) and poor oral bioavailability (2.22% ± 2.13%) while the oral bioavailability of 3,4-DMS was even poorer than 2,3-DMS. Clearly, the location of the methoxy groups had a significant impact on the pharmacokinetics of resveratrol analogs. This study provided useful information for the design of resveratrol derivatives in future study.

Abstract
trans-2,6-Difluoro-4'-N,N-dimethylaminostilbene (DFS), a synthetic stilbene, displayed potent pre-clinical anti-cancer activities exceeding that observed for naturally occurring resveratrol. In this study, a simple and sensitive HPLC method was developed and validated to quantify DFS in rat plasma. The lower limit of quantification (LLOQ) was 5 ng/ml. The intra- and inter-day variation in terms of relative standard deviation (RSD) was all less than 10%. The bias rate ranged from -11.5% to 6.2% while the absolute recovery ranged from 94.1 ± 2.3 to 97.3 ± 4.4%. The pharmacokinetic profiles of DFS were examined in Sprague-Dawley rats after intravenous administration (2 mg/kg). DFS displayed moderate clearance (Cl=61.5 ± 17.7 ml/min/kg) and a relatively prolonged terminal elimination half-life (t(1/2 λz)) of 351 ± 180 min. Aqueous solubility played a crucial role in the oral absorption of DFS. When DFS was given as a suspension (6 mg/kg), the absolute oral bioavailability (F) was almost negligible. However, when DFS was given in a solution prepared with hydroxypropyl-β-cyclodextrin (6 mg/kg), the F was 12.4 ± 10.7%. Dose-escalation to 15 mg/kg resulted in much higher systemic exposure (F=40.2 ± 10.0%). As DFS is orally available after formulation with hydroxypropyl-β-cyclodextrin and pharmacologically active systemic concentrations could be achieved after a single oral dose, the use of DFS as a cancer chemopreventive/chemotherapeutic agent is possible.

Abstract
We investigated the contribution of cytochrome P-450 1B1 (CYP1B1) to renal dysfunction and organ damage associated with ANG II-induced hypertension in rats. ANG II (300 ng·kg(-1)·min(-1)) or vehicle were infused for 2 wk, with daily injections of a selective CYP1B1 inhibitor, 2,4,3',5'-tetramethoxystilbene (TMS; 300 μg/kg ip), or its vehicle. ANG II increased blood pressure and renal CYP1B1 activity that were prevented by TMS. ANG II also increased water intake and urine output, decreased glomerular filtration rate, increased urinary Na(+) and K(+) excretion, and caused proteinuria, all of which were prevented by TMS. ANG II infusion caused hypertrophy, endothelial dysfunction, and increased reactivity of renal and interlobar arteries to vasoconstrictor agents and renal vascular resistance and interstitial fibrosis as indicated by accumulation of α-smooth muscle actin, fibronectin, and collagen, and inflammation as indicated by increased infiltration of CD-3(+) cells; these effects were inhibited by TMS. ANG II infusion also increased production of reactive oxygen species (ROS) and activities of NADPH oxidase, ERK1/2, p38 MAPK, and c-Src that were prevented by TMS. TMS alone had no effect on any of the above parameters. These data suggest that CYP1B1 contributes to the renal pathophysiological changes associated with ANG II-induced hypertension, most likely via increased ROS production and activation of ERK1/2, p38 MAPK, and c-Src and that CYP1B1 could serve as a novel target for treating renal disease associated with hypertension.

Preclinical pharmacokinetic evaluation of resveratrol trimethyl ether in sprague-dawley rats: the impacts of aqueous solubility, dose escalation, food and repeated dosing on oral bioavailability.

Abstract
Resveratrol trimethyl ether (trans-3,5,4'-trimethoxystilbene, RTE) is a naturally occurring and pharmacologically active resveratrol derivative. To evaluate its suitability as a drug candidate, a pharmacokinetic study was carried out in Sprague-Dawley rats with the emphasis to identify the impact of aqueous solubility, dose escalation, food, and repeated dosing on its oral bioavailability. Upon single intravenous administration (5 mg/kg), RTE displayed moderate clearance (35.5 ± 5.3 mL/min/kg) and a fairly long terminal elimination half-life (511 ± 136 min); dose escalation (5-20 mg/kg) did not cause nonlinear pharmacokinetics. When given orally in suspension (60 mg/kg), RTE was poorly absorbed with negligible bioavailability (< 1.5%), fasting further decreased its bioavailability (<1%). However, when administered in a solution formulated with randomly methylated-β-cyclodextrin (15 mg/kg), RTE was rapidly absorbed with good bioavailability (46.5 ± 4.8%). Dose escalation resulted in increased bioavailability (64.6 ± 8.0%) at the dose of 60 mg/kg. Repeated RTE dosing (7 daily oral doses) did not alter the clearance, terminal elimination half-life and bioavailability. In summary, the aqueous solubility of RTE was a barrier to oral absorption; repeated RTE administrations did not alter its pharmacokinetic profiles; as RTE possessed appropriate pharmacokinetic profiles, further investigation on RTE as a drug candidate is warranted.

Abstract
A simple HPLC method was established to quantify trans-3,4,5,4'-tetramethoxystilbene (MR-4 or DMU-212) in rat plasma. Chromatographic separation was obtained with a reversed-phase HPLC column through an 11 min gradient delivery of a mixture of acetonitrile and water at a flow rate of 1.5 mL/min at 50 °C. The limit of quantification was 15 ng/mL. The intra- and interday precisions in terms of relative standard deviation were <9% at all concentrations. Similarly, the accuracy was good, and the bias rates ranged within ±7%. The pharmacokinetic profiles of MR-4 were subsequently assessed in rats using 2-hydroxypropyl-β-cyclodextrin as a dosing vehicle. Upon intravenous administration, MR-4 displayed moderate clearance (46.5 ± 7.6 mL/min/kg) and terminal elimination half-life (154 ± 80 min). However, the absolute oral bioavailability of MR-4 was low (6.31 ± 3.30%). Future investigation on MR-4 as a chemotherapeutic agent should be focused on colorectal cancers.
