Integration of transdermal chemistry and network pharmacology to decipher the mechanism of ShexiangZhuifeng analgesic plaster to treat rheumatoid arthritis. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 108:154507. [PMID: 36334391 DOI: 10.1016/j.phymed.2022.154507] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 10/04/2022] [Accepted: 10/16/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Transdermal patches are an effective form of treatment for rheumatoid arthritis (RA), and they have a number of benefits, including patient compliance, accessibility, and low systemic toxicity. ShexiangZhuifeng Analgesic Plaster (SZAP), a patch made up of many traditional medicines, has been successfully utilized in numerous clinical trials to treat RA. However, information about anti-RA processes and transdermal active components is still emerging. PURPOSE Our objectives were to identify the transdermal active components of SZAP and investigate its anti-RA mechanisms, primarily focused on joint inflammation. METHODS The collagen-induced arthritis (CIA) rats were created first, and then the arthritis score, Paw thickness, and morphology feature of joint synovial were assessed after 7 days of therapy with SZAP. Moreover, the Franz diffusion cell and UPLC-MS technologies were combined to identify and measure the transdermal active ingredients of SZAP. Furthermore, network pharmacology was utilized to anticipate the putative the mechanism of SZAP for treating RA. Finally, the results of network pharmacology were validated using LPS-induced RAW 264.7 cells and CIA rats. RESULTS SZAP significantly reduced paw thickness, arthritic score and pathological characteristics of joint synovitis in (CIA) rats. Additionally, 12 transdermal active components of SZAP were identified, and network pharmacology prediction results suggested that SZAP may alleviate joint synovial inflammation by blocking the Akt/mTOR/HIF-1 pathway. Our investigations' findings demonstrated that SZAP dramatically reduced the concentrations of excess cytokines (IL6, VEGF, and TNF-α), as well as the protein overexpression of the AKT/mTOR/HIF- pathway (HIF-1, p-AKT, and p-mTOR), whereas its anti-inflammation effect was reversed once AKT or mTOR was activated. CONCLUSION By blocking the AKT/mTOR/HIF-1 pathway, SZAP can lessen the release of inflammatory mediators, which reduces joint synovial inflammation associated with RA. The pharmacological evaluation of TCM transdermal drug delivery formulations like SZAP may be amenable to the integration of transdermal chemistry and network pharmacology approaches.

[PMID: 35667582 DOI: 10.1016/j.jep.2022.115437] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 05/27/2022] [Accepted: 06/02/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Shaoyao-Gancao-Fuzi decoction (SGFD), a well-known traditional Chinese medicine formula, was originally described in "Treatise on Febrile Diseases" and has been extensively used to dispel wind, eliminate dampness and treat paralysis. It is widely used for the treatment of rheumatoid arthritis in clinic. However, the effect of SGFD on the activity of cytochrome P450 enzymes (CYP450s) and the herb-drug interactions are rarely studied. OBJECTIVE The aim of this study was to investigate the effect of SGFD on the activity of CYP450s and evaluate the potential herb-drug interactions between SGFD and tofacitinib, commonly used disease-modifying antirheumatic drug in rheumatoid arthritis. MATERIALS AND METHODS The cocktail approach was employed to assess the effect of SGFD on the activity of CYP1A2, 3A4, 2A6, 2E1, and 2C9. The pharmacokinetic profile of oral administration of tofacitinib in rats after two weeks of treatment with SGFD was investigated. RT-qPCR and molecular docking were performed to unveil the underlying mechanism of the herb-drug interaction. RESULTS SGFD had no effect on the activities of CYP2E1 and 2C9, had a weak effect on CYP2A6, and had activatory effect on CYP1A2. However, it had a dramatically inhibitory effect on the activity of CYP3A4. Simultaneously, the values of Cmax and AUC0-∞ of tofacitinib were obviously increased after treatment with SGFD for 14 days. The mechanism study manifested that SGFD significantly reduced the gene transcription of CYP3A. Molecular docking work confirmed that the inhibitory activity of glycyrrhetinic acid, glycyrrhizic acid and liquiritin, the main ingredients of SGFD, occurred by occupying the active sites of CYP3A4 and by making favorable interactions with its key residues. CONCLUSIONS The system exposure of tofacitinib was increased by SGFD. SGFD could affect the activity and gene expression of the key metabolic enzyme CYP3A. These findings give a clear understanding to predict herb-drug interaction of SGFD for safe clinical use in future.

Anti-inflammatory Mechanism of Action of Benzoylmesaconine in Lipopolysaccharide-Stimulated RAW264.7 Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:7008907. [PMID: 35873638 PMCID: PMC9300273 DOI: 10.1155/2022/7008907] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 06/06/2022] [Accepted: 06/13/2022] [Indexed: 11/18/2022]
Abstract
Background Benzoylmesaconine (BMA), the most abundant monoester alkaloid in Aconitum plants, has some biological activities and is a potential therapeutic agent for inflammation-related diseases. However, the potential anti-inflammatory mechanisms of BMA have not been clarified. Purpose This study aimed to investigate the underlying molecular mechanisms of the anti-inflammatory action of this compound using lipopolysaccharide (LPS)-activated RAW264.7 macrophages. Methods The release of pro-inflammatory cytokines and mediators were detected by nitric oxide (NO) assays, reactive oxygen species (ROS) assays, and enzyme-linked immunosorbent assays (ELISA) in LPS-activated RAW264.7 macrophage cells. Quantitative real-time PCR was used to measure the gene expression of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). Cell viability was determined using a cell counting kit-8 (CCK-8) assay. The expression of iNOS, COX-2, mitogen-activated protein kinase (MAPK), and nuclear factor-κB (NF-κB)-related proteins were detected by western blot, and nuclear translocation of p65 was observed by immunofluorescence. Results BMA significantly decreased the production of IL-1β, IL-6, TNF-α, PGE2, NO, and ROS and inhibited the protein and mRNA levels of COX-2 and iNOS in LPS-activated RAW264.7 macrophages. Moreover, LPS-induced phosphorylation of IκBα, JNK, p38, and ERK; degradation of IκBα; and nuclear translocation of p65 were significantly suppressed by BMA treatment. Conclusion These findings demonstrate that the anti-inflammatory effect of BMA was through the suppression of the NF-κB and MAPK signaling pathways and that it may be a therapeutic agent targeting specific signal transduction events required for inflammation-related diseases.

Abstract
You-Gui-Wan is a traditional Chinese patent medicine that has been extensively used to treat kidney-yang deficiency syndrome. An HPLC-MS/MS method was developed to measure contents of 12 components of You-Gui-Wan in rat plasma. Considering that pathological changes might directly affect the pharmacokinetic behavior of drugs, this method was further applied to compare pharmacokinetics between normal and osteoporotic animals. The results indicated that osteoporosis significantly altered the pharmacokinetic characteristics of the 12 components. Thus, the pharmacokinetics of You-Gui-Wan evaluated under osteoporotic conditions were much closer to clinical practice than that in normal physiological states. Thus, the optimized analytical method, along with the pharmacokinetic evaluation in the osteoporotic model may offer a more comprehensive understanding to elucidate the anti-osteoporosis mechanism of You-Gui-Wan. These findings may aid in developing a more effective treatment plan for osteoporosis. This article is protected by copyright. All rights reserved.

Abstract
Aconitum and its products have been used in Asia for centuries to treat various ailments, including arthritis, gout, cancer, and inflammation. In general, their preparations and dispensing have been restricted to qualified folk medicine healers due to their low safety index and reported toxicity. In the past few decades, official guidelines have been introduced in Asian pharmacopeias to control Aconitum herbal products. However, these guidelines were based on primitive analytical techniques for the determination of the whole Aconitum alkaloids and were unable to distinguish between toxic and nontoxic components. Recent advances in analytical techniques, especially high performance liquid chromatography (HPLC) and electrophoresis coupled with highly sensitive detectors, allowed rapid and accurate determination of Aconitum secondary metabolites. Reports focusing on liquid chromatography/mass spectrometry analysis of Aconitum and its herbal products are discussed in the current review. This review can be used by the health liquid chromatography/mass spectrometry regulatory authorities for updating pharmacopeial guidelines of Aconitum and its herbal products.

Abstract
Aconite poisoning continues to be a major type of poisoning caused by herbal drugs in many countries. Nevertheless, despite its toxic characteristics, aconite is used because of its valuable therapeutic benefits. The aim of the present study was to determine the distribution of toxic alkaloids in tissues of aconite roots through chemical profiling. Three species were studied, all being used in traditional Chinese Medicine (TCM) and traditional Indian medicine (Ayurveda), namely: Aconitum carmichaelii, Aconitum kusnezoffii and Aconitum heterophyllum. Laser micro-dissection was used for isolation of target microscopic tissues, such as the metaderm, cortex, xylem, pith, and phloem, with ultra-high performance liquid chromatography equipped with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF MS) employed for detection of metabolites. Using a multi-targeted approach through auto and targeted LC-MS/MS, 48 known compounds were identified and the presence of aconitine, mesaconitine and hypaconitine that are the biomarkers of this plant was confirmed in the tissues. These results suggest that the three selected toxic alkaloids were exclusively found in A. carmichaelii and A. kusnezoffii. The most toxic components were found in large A. carmichaelii roots with more lateral root projections, and specifically in the metaderm, cork and vascular bundle tissues. The results from metabolite profiling were correlated with morphological features to predict the tissue specific distribution of toxic components and toxicity differences among the selected species. By careful exclusion of tissues having toxic diester diterpenoid alkaloids, the beneficial effects of aconite can still be retained and the frequency of toxicity occurrences can be greatly reduced. Knowledge of tissue-specific metabolite distribution can guide users and herbal drug manufacturers in prudent selection of relatively safer and therapeutically more effective parts of the root. The information provided from this study can contribute towards improved and effective management of therapeutically important, nonetheless, toxic drug such as Aconite.

Abstract
Abstract
Objectives
A number of species belonging to herbal genus Aconitum are well-known and popular for their medicinal benefits in Indian, Vietnamese, Korean, Japanese, Tibetan and Chinese systems of medicine. It is a valuable drug as well as an unpredictable toxic material. It is therefore imperative to understand and control the toxic potential of herbs from this genus. In this review, the ethnomedicinal, phytochemistry, pharmacology, structure activity relationship and toxicology studies of Aconitum were presented to add to knowledge for their safe application.
Key findings
A total of about 76 of all aconite species growing in China and surrounding far-east and Asian countries are used for various medical purposes. The main ingredients of aconite species are alkaloids, flavonoids, free fatty acids and polysaccharides. The tuberous roots of genus Aconitum are commonly applied for various diseases such as rheumatic fever, painful joints and some endocrinal disorders. It stimulates the tip of sensory nerve fibres. These tubers of Aconitum are used in the herbal medicines only after processing. There remain high toxicological risks of the improper medicinal applications of Aconitum. The cardio and neurotoxicities of this herb are potentially lethal. Many analytical methods have been reported for quantitatively and qualitatively characterization of Aconitum.
Summary
Aconitum is a plant of great importance both in traditional medicine in general and in TCM in particular. Much attention should be put on Aconitum because of its narrow therapeutic range. However, Aconitum's toxicity can be reduced using different techniques and then benefit from its pharmacological activities. New methods, approaches and techniques should be developed for chemical and toxicological analysis to improve its quality and safety.

Abstract
The aim of this study is to investigate whether or not You Gui Wan (YGW), a classical herbal formula in Traditional Chinese Medicine (TCM), has an impact on rat uterine and vaginal atrophic processes induced by ovariectomy (OVX). Thirty-four OVX Sprague-Dawley (SD) rats were randomly divided into three sets, and orally administrated with YGW decoction, saline or estrogen for 11 weeks, respectively. Histomorphological changes of the uterus and vagina, and serum estradiol levels were then compared. Results showed that OVX caused a dramatic atrophy of the uterus and vagina in the rats. Estrogen replacement reversed the effect of OVX, but with a side effect of endometrial hyperplasia. YGW had no significant effect on blood estradiol concentration or uterine histology, but it significantly overturned the atrophic processes of the vaginal fold and blood vessels in the lamina propria. In order to initially explore the mechanisms underlying these effects, immunostaining of estrogen receptor (ER)-α and -β in the vagina was performed. It was shown that OVX reduced expressions of ER while YGW and estrogen replacement reversed this reduction. Our findings suggest that YGW can reverse the atrophic effect of OVX on rat vaginal plica and blood vessels in the lamina propria with little adverse effect on endometrial hyperplasia. This indicates the herbal formula as an alternative to hormone replacement therapy in the management of menopausal vaginal atrophy. Recovery of ER expressions in the vagina might be one of mechanisms underlying the effects of YGW.

Abstract
Aconitum species have been used in China as an essential drug in Traditional Chinese Medicine (TCM) for 2000 years. Reviewing the clinical application of Aconitum, their pharmacological effects, toxicity and detoxifying measures, herb-herb interactions, clinical taboos, famous herbal formulas, traditional and current herbal processing methods based upon a wide range of literature investigations serve as a case study to explore the multidisciplinary implications of botanicals used in TCM. The toxicological risk of improper usage of Aconitum remains very high, especially in countries like China, India and Japan. The toxicity of Aconitum mainly derives from the diester diterpene alkaloids (DDAs) including aconitine (AC), mesaconitine (MA) and hypaconitine (HA). They can be decomposed into less or non-toxic derivatives through Chinese traditional processing methods (Paozhi), which play an essential role in detoxification. Using Paozhi, the three main forms of processed aconite -- yanfuzi, heishunpian and baifupian -- can be obtained (CPCommission, 2005). Moreover, some new processing techniques have been developed in China such as pressure-steaming. The current development of fingerprint assays, in particular HPLC, has set a good basis to conduct an appropriate quality control for TCM crude herbs and their ready-made products. Therefore, a stipulation for a maximum level of DDA content of Aconitum is highly desirable in order to guarantee the clinical safety and its low toxicity in decoctions. Newly developed HPLC methods have made the accurate and simultaneous determination and quantification of DDA content interesting.
