Abstract
INTRODUCTION The function of promoting bone regeneration of Moutan Cortex (MC), a traditional Chinese medicine, has been widely known but, the effective components of MC in promoting osteoblast-mediated bone regeneration were still unclear. OBJECTIVE The method of osteoblast membrane bio-specific extraction conjugated with HPLC analysis was established to screen bone regeneration active components from MC. METHODS The fingerprints, washing eluate and desorption eluate of MC extract were analyzed by the established HPLC-DAD method. The established MC3T3-E1 cells membrane chromatography method was used for the bio-specific extraction of MC. The isolated compounds were identified by MS spectrometry. The effects and possible mechanisms of the isolated compounds were evaluated by molecular docking, ALP activity, cell viability by MTT Assay and proteins expression by Western Blot Analysis. RESULTS The active compound responsible for bone regeneration from MC was isolated using the established method of osteoblast membrane bio-specific extraction conjugated with HPLC analysis, and it was identified as 1,2,3,4,6-penta-O-β-galloyl-D-glucose (PGG) by MS spectrometry. It was further demonstrated through molecular docking that PGG could fit well into the functional ALP, BMP2, and Samd1 binding pocket. The proliferation of osteoblasts was promoted, the level of ALP was increased, and the protein expression of BMP2 and Smad1 was increased as shown by further pharmacological verification. CONCLUSION It was concluded that PGG, the bone regeneration active compound from MC, could stimulate the proliferation of osteoblasts to promote osteoblast differentiation, and its mechanism might be related to the BMP/Smad1 pathway.

Pentagalloyl Glucose: A Review of Anticancer Properties, Molecular Targets, Mechanisms of Action, Pharmacokinetics, and Safety Profile. Molecules 2023; 28:4856. [PMID: 37375411 DOI: 10.3390/molecules28124856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 06/07/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023] Open
Abstract
Pentagalloyl glucose (PGG) is a natural hydrolyzable gallotannin abundant in various plants and herbs. It has a broad range of biological activities, specifically anticancer activities, and numerous molecular targets. Despite multiple studies available on the pharmacological action of PGG, the molecular mechanisms underlying the anticancer effects of PGG are unclear. Here, we have critically reviewed the natural sources of PGG, its anticancer properties, and underlying mechanisms of action. We found that multiple natural sources of PGG are available, and the existing production technology is sufficient to produce large quantities of the required product. Three plants (or their parts) with maximum PGG content were Rhus chinensis Mill, Bouea macrophylla seed, and Mangifera indica kernel. PGG acts on multiple molecular targets and signaling pathways associated with the hallmarks of cancer to inhibit growth, angiogenesis, and metastasis of several cancers. Moreover, PGG can enhance the efficacy of chemotherapy and radiotherapy by modulating various cancer-associated pathways. Therefore, PGG can be used for treating different human cancers; nevertheless, the data on the pharmacokinetics and safety profile of PGG are limited, and further studies are essential to define the clinical use of PGG in cancer therapies.

The most bioactive fraction of stir-fried Radix Paeoniae Alba regulating IL-6/STAT3 signaling pathway in allergic asthma mouse. JOURNAL OF ETHNOPHARMACOLOGY 2023; 301:115821. [PMID: 36220510 DOI: 10.1016/j.jep.2022.115821] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 09/23/2022] [Accepted: 10/06/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Paeoniae Alba (RPA), a traditional Chinese medicine, has been used frequently in the treatment of asthma. Previous studies demonstrated the dichloromethane fraction of Stir-Frying RPA (FDCM) enhanced the effect of anti-allergic asthma compared with the dichloromethane fraction of RPA (DCM). AIM OF THE STUDY The significant increasing of Paeoniflorin (PF), ethyl gallate (EG), 1,2,3,4,6-pentagalloylglucose (PGG) had been observed in FDCM. This study aimed to investigate the effects and mechanisms of these compounds from FDCM in ovalbumin (OVA)-induced allergic asthma mouse model. MATERIALS AND METHODS The significant difference contents compounds fraction (FB-40) and other fractions in FDCM were enriched by Medium Pressure Liquid Chromatography (MPLC). The pharmacodynamics was verified among all fractions in OVA-induced allergic asthma mice. Moreover, the drug dose dependence of FB-40 (0.42 mg/kg, 0.21 mg/kg, and 0.07 mg/kg), which were the most active fraction from FDCM for anti-allergic asthma, was explored. The expression of IL-6, p-STAT3, and STAT3 was analyzed by Western blot analysis. In addition, the main components of FB-40 were identified by UPLC with standards. Finally, the anti-inflammatory effects of the main components from FB-40 were detected by LPS-stimulated BEAS-2B cells using an Elisa assay. RESULTS The results showed that FB-40 was the most active fraction from FDCM, which could significantly improve the lung tissue pathological condition, and decrease the number of inflammatory cells in bronchoalveolar lavage fluid (BALF). It had greater pharmacological activity than its main component PF. FB-40 also showed dose dependence and regulated the IL-6/STAT3 signaling pathway in allergic asthma mice. Besides, PF, Albiflorin (AF), PGG, EG, and 1,2,3,6-Tetra-O-galloyl-β-D-glucose (TGG) from FB-40 were identified by UPLC with the standard. At last, in the LPS-induced BEAS-2B cell experiments, EG, PGG, 1,2,3,6-Tetra-O-galloyl-β-D-glucose (TGG) showed stronger inhibiting activities of cytokine than the monoterpenoid glycosides (PF and AF). CONCLUSION The research proved that FB-40 was an active fraction in FDCM, which regulates IL-6/STAT3 Signaling Pathway to ameliorate allergic asthma. Gallic acids including TGG and PGG, and EG also play a role in the treatment of allergic asthma in FB-40.

Hydrolyzable Tannins in the Management of Th1, Th2 and Th17 Inflammatory-Related Diseases. Molecules 2022; 27:molecules27217593. [DOI: 10.3390/molecules27217593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/30/2022] [Accepted: 11/03/2022] [Indexed: 11/09/2022] Open
Abstract
Plants rich in hydrolyzable tannins were traditionally used all over the world for a variety of chronic inflammatory disorders, including arthritis, colitis, and dermatitis. However, the knowledge of their immunological targets is still limited though fundamental for their rational use in phytotherapy. The recent advances regarding the pathogenesis of inflammatory-based diseases represent an opportunity to elucidate the pharmacological mechanism of plant-derived metabolites with immunomodulatory activity. This review collects recent articles regarding the role of hydrolyzable tannins and their gut metabolites in Th1, Th2, and Th17 inflammatory responses. In line with the traditional use, rheumatoid arthritis (RA), inflammatory bowel diseases (IBDs), psoriasis, atopic dermatitis (AD), and asthma were the most investigated diseases. A substantial body of in vivo studies suggests that, beside innate response, hydrolyzable tannins may reduce the levels of Th-derived cytokines, including IFN-γ, IL-17, and IL-4, following oral administration. The mode of action is multitarget and may involve the impairment of inflammatory transcription factors (NF-κB, NFAT, STAT), enzymes (MAPKs, COX-2, iNOS), and ion channels. However, their potential impact on pathways with renewed interest for inflammation, such as JAK/STAT, or the modulation of the gut microbiota demands dedicate studies.

Abstract
Respiratory diseases are the major cause of human illness and death around the world. Despite advances in detection and treatment, very few classes of safe and effective therapy have been introduced to date. At present, phytochemicals are getting more attention because of their diverse beneficial activities and minimal toxicity. Tannins are polyphenolic secondary metabolites with high molecular weights, which are naturally present in a wide variety of fruits, vegetables, cereals, and leguminous seeds. Many tannins are endowed with well-recognized protective properties, such as anti-cancer, anti-microbial, anti-oxidant, anti-hyperglycemic, and many others. This review summarizes a large body of experimental evidence implicating that tannins are helpful in tackling a wide range of non-malignant respiratory diseases including acute lung injury (ALI), pulmonary fibrosis, asthma, pulmonary hypertension, and chronic obstructive pulmonary disease (COPD). Mechanistic pathways by which various classes of tannins execute their beneficial effects are discussed. In addition, clinical trials and our perspective on future research with tannins are also reviewed.

Pentagalloylglucose Inhibits the Replication of Rabies Virus via Mediation of the miR-455/SOCS3/STAT3/IL-6 Pathway. J Virol 2019; 93:JVI.00539-19. [PMID: 31243136 DOI: 10.1128/jvi.00539-19] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 06/23/2019] [Indexed: 02/07/2023] Open
Abstract
Our previous study showed that pentagalloylglucose (PGG), a naturally occurring hydrolyzable phenolic tannin, possesses significant anti-rabies virus (RABV) activity. In BHK-21 cells, RABV induced the overactivation of signal transducer and activator of transcription 3 (STAT3) by suppressing the expression of suppressor of cytokine signaling 3 (SOCS3). Inhibition of STAT3 by niclosamide, small interfering RNA, or exogenous expression of SOCS3 all significantly suppressed the replication of RABV. Additionally, RABV-induced upregulation of microRNA 455-5p (miR-455-5p) downregulated SOCS3 by directly binding to the 3' untranslated region (UTR) of SOCS3. Importantly, PGG effectively reversed the expression of miR-455-5p and its following SOCS3/STAT3 signaling pathway. Finally, activated STAT3 elicited the expression of interleukin-6 (IL-6), thereby contributing to RABV-associated encephalomyelitis; however, PGG restored the level of IL-6 in vitro and in vivo in a SOCS3/STAT3-dependent manner. Altogether, these data identify a new miR-455-5p/SOCS3/STAT3 signaling pathway that contributes to viral replication and IL-6 production in RABV-infected cells, with PGG exerting its antiviral effect by inhibiting the production of miR-455-5p and the activation of STAT3.IMPORTANCE Rabies virus causes lethal encephalitis in mammals and poses a serious public health threat in many parts of the world. Numerous strategies have been explored to combat rabies; however, their efficacy has always been unsatisfactory. We previously reported a new drug, PGG, which possesses a potent inhibitory activity on RABV replication. Herein, we describe the underlying mechanisms by which PGG exerts its anti-RABV activity. Our results show that RABV induces overactivation of STAT3 in BHK-21 cells, which facilitates viral replication. Importantly, PGG effectively inhibits the activity of STAT3 by disrupting the expression of miR-455-5p and increases the level of SOCS3 by directly targeting the 3' UTR of SOCS3. Furthermore, the downregulated STAT3 inhibits the production of IL-6, thereby contributing to a reduction in the inflammatory response in vivo Our study indicates that PGG effectively inhibits the replication of RABV by the miR-455-5p/SOCS3/STAT3/IL-6-dependent pathway.

Abstract
Background and Purpose Hypertension is a multifactorial disease, manifested by vascular dysfunction, increased superoxide production, and perivascular inflammation. In this study, we have hypothesized that 1,2,3,4,6‐penta‐O‐galloyl‐β‐d‐glucose (PGG) would inhibit vascular inflammation and protect from vascular dysfunction in an experimental model of hypertension. Experimental Approach PGG was administered to mice every 2 days at a dose of 10 mg·kg−1 i.p during 14 days of Ang II infusion. It was used at a final concentration of 20 μM for in vitro studies in cultured cells. Key Results Ang II administration increased leukocyte and T‐cell content in perivascular adipose tissue (pVAT), and administration of PGG significantly decreased total leukocyte and T‐cell infiltration in pVAT. This effect was observed in relation to all T‐cell subsets. PGG also decreased the content of T‐cells bearing CD25, CCR5, and CD44 receptors and the expression of both monocyte chemoattractant protein 1 (CCL2) in aorta and RANTES (CCL5) in pVAT. PGG administration decreased the content of TNF+ and IFN‐γ+ CD8 T‐cells and IL‐17A+ CD4+ and CD3+CD4−CD8− cells. Importantly, these effects of PGG were associated with improved vascular function and decreased ROS production in the aortas of Ang II‐infused animals independently of the BP increase. Mechanistically, PGG (20 μM) directly inhibited CD25 and CCR5 expression in cultured T‐cells. It also decreased the content of IFN‐γ+ CD8+ and CD3+CD4−CD8− cells and IL‐17A+ CD3+CD4−CD8− cells. Conclusion and Implication PGG may constitute an interesting immunomodulating strategy in the regulation of vascular dysfunction and hypertension.

Abstract
Colon cancer is the third most common malignancy in both sexes of Korea. Here, we investigated anti-colorectal cancer effects of 1,2,3,4,6-penta-O-galloyl-β-d-glucose (PGG), a gallotannin from Galla rhois, and its possible mechanisms. PGG induced cytotoxicity and decreased proliferation of colon cancer cells without affecting normal colon fibroblasts. PGG inhibited clonogenic ability and induced apoptosis in cancer cells. One of the underlying mechanisms of the anti-cancer effect exerted by PGG, was owing to the induction p53 expression, a well-known tumor suppressor, and increased in P21, the representative target gene of p53. PGG affected cell-cycle- or apoptosis-related proteins such as cyclin E, CDK2, and Bcl-2, cleaved caspase-3. Also, PGG induced caspase-3/7 activity. These data suggest that PGG exerts anti-colorectal cancer effects.

Abstract
The compound 1,2,3,4,6-penta-O-galloyl-β-d-glucose (PGG), a gallotannin present in various plants such as Rhus chinensis Mill and Paeonia suffruticosa, has a broad spectrum of antiviral effects. The present study investigated its potency against infection of mice with rabies virus (RABV). Results demonstrated that PGG strongly inhibited virus titers (50-fold), viral mRNA expression (up to 90%), and protein synthesis in vitro. Importantly, we found that PGG not only suppressed viral adsorption and entry, but also directly inactivated RABV through suppression of autophagy by mediating activation of the mTOR-dependent autophagy signaling pathway. In vivo, PGG (10 mg/kg) alleviated the clinical symptoms and reduced the mortality of infected mice by 27.3%. Collectively, our results indicate that PGG has potent anti-RABV effect, and merits further investigation as an anti-RABV drug.
