Betulinic Acid Attenuates Osteoarthritis via Limiting NLRP3 Inflammasome Activation to Decrease Interleukin-1 β Maturation and Secretion. Mediators Inflamm 2023; 2023:3706421. [PMID: 37789884 PMCID: PMC10545461 DOI: 10.1155/2023/3706421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 07/09/2023] [Accepted: 08/01/2023] [Indexed: 10/05/2023] Open
Abstract
Introduction Osteoarthritis (OA) is the most common degenerative joint disorder. Prior studies revealed that activation of NLRP3 inflammasome could promote the activation and secretion of interleukin-1β (IL-1β), which has an adverse effect on the progression of OA. Betulinic acid (BA) is a compound extract of birch, whether it can protect against OA and the mechanisms involved are still unknown. Materials and Methods In vivo experiments, using gait analysis, ELISA, micro-CT, and scanning electron microscopy (SEM), histological staining, immunohistological (IHC) and immunofluorescence (IF) staining, and atomic force microscopy (AFM) to assess OA progression after intraperitoneal injection of 5 and 15 mg/kg BA in an OA mouse model. In vitro experiments, caspase-1, IL-1β, and the N-terminal fragment of gasdermin D (GSDMD-NT) were measured in bone marrow-derived macrophages (BMDMs) by using ELISA, western blot, and immunofluorescence staining. Results We demonstrated that OA progression can be postponed with intraperitoneal injection of 5 and 15 mg/kg BA in an OA mouse model. Specifically, BA postponed DMM-induced cartilage deterioration, alleviated subchondral bone sclerosis, and relieved synovial inflammation. In vitro studies, the activated NLRP3 inflammasome produces mature IL-1β by facilitating the cleavage of pro-IL-1β, and BA could inhibit the activation of NLRP3 inflammasome in BMDMs. Conclusions Taken together, our analyses revealed that BA attenuates OA via limiting NLRP3 inflammasome activation to decrease the IL-1β maturation and secretion.

Abstract
Liquiritigenin (LTG) and its bioprecursor isoliquiritigenin(ISL), the main bioactives from roots of Glycyrrhiza genus are progressively documented as a potential pharmacological agent for the management of chronic diseases. The aim of this study was to evaluate the pharmacological potential of liquiritigenin, isoliquiritigenin rich extract of Glycyrrhiza glabra roots (IVT-21) against the production of pro-inflammatory cytokines from activated macrophages as well as further validated the efficacy in collagen-induced arthritis model in rats. We also performed the safety profile of IVT-21 using standard in-vitro and in-vivo assays. Results of this study revealed that the treatment of IVT-21 and its major bioactives (LTG, ISL) was able to reduce the production of pro-inflammatory cytokines (TNF-α, IL-6) in LPS-activated primary peritoneal macrophages in a dose-dependent manner compared with vehicle-alone treated cells without any cytotoxic effect on macrophages. In-vivo efficacy profile against collagen-induced arthritis in Rats revealed that oral administration of IVT-21 significantly reduced the arthritis index, arthritis score, inflammatory mediators level in serum. IVT-21 oral treatment is also able to reduce the NFкB-p65 expression as evidence of immunohistochemistry in knee joint tissue and mRNA level of pro-inflammatory cytokines in paw tissue in a dose-dependent manner when compared with vehicle treated rats. Acute oral toxicity profile of IVT-21 demonstrated that it is safe up to 2000 mg/kg body weight in experimental mice. This result suggests the suitability of IVT-21 for further study in the management of arthritis and related complications.

Abstract
Renal cancer is the most lethal urological cancer and characterized by high metastasis rate at initial diagnosis and drug resistance to current chemotherapeutics. Betulinic acid is a pentacyclic triterpene with broad biological activity that occurs naturally in variety of plants. Even though the anti-cancer efficacy of betulinic acid have been reported by many studies, the information about the pathways and the molecules which are affected by betulinic acid in renal cancer are limited. Epithelial-mesenchymal transition (EMT) is considered as the initial step of metastasis and contributes to drug resistance of cancer cells. Depending on the role of EMT in cancer progression and drug resistance, targeting EMT may represent an effective strategy in this context. Therefore, we aimed to investigate the anti-metastatic effects of betulinic acid on renal cell carcinoma cells by evaluating two EMT markers, SNAIL-1, and SDC-2. Following the treatment of betulinic acid at determined doses by WST-1 cytotoxicity assay in our previous study, SDC-2 expression level was decreased in both cell lines. Additionally, in correlation with this result, we also found a reduction in SDC-2 and SNAIL-1 protein levels which are measured by ELISA. Furthermore, the migration and invasion capacities were suppressed by betulinic acid treatment in metastatic renal adenocarcinoma ACHN cells. Taken together, our findings indicate that betulinic acid may constitute a potential treatment approach for renal cancer with further investigations.

Abstract
Triterpenic acids are a widespread class of phytocompounds which have been found to possess valuable therapeutic properties such as anticancer, anti-inflammatory, hepatoprotective, cardioprotective, antidiabetic, neuroprotective, lipolytic, antiviral, and antiparasitic effects. They are a subclass of triterpenes bearing a characteristic lipophilic structure that imprints unfavorable in vivo properties which subsequently limit their applications. The early investigation of the mechanism of action (MOA) of a drug candidate can provide valuable information regarding the possible side effects and drug interactions that may occur after administration. The current paper aimed to summarize the most recent (last 5 years) studies regarding the MOA of betulinic acid, boswellic acid, glycyrrhetinic acid, madecassic acid, moronic acid, and pomolic acid in order to provide scientists with updated and accessible material on the topic that could contribute to the development of future studies; the paper stands as the sequel of our previously published paper regarding the MOA of triterpenic acids with therapeutic value. The recent literature published on the topic has highlighted the role of triterpenic acids in several signaling pathways including PI3/AKT/mTOR, TNF-alpha/NF-kappa B, JNK-p38, HIF-α/AMPK, and Grb2/Sos/Ras/MAPK, which trigger their various biological activities.

Abstract
Rheumatoid arthritis (RA) is a systemic immune disease. Rho family GTPase 3 (RND3) has been reported to play an important role in inflammatory diseases. In this study, the expression of RND3 in RA was analyzed by gene chips. After RND3 was overexpressed, cell counting kit-8 assay was to detect the viability of fibroblast-like synovial cells (RA-FLSs). Transwell assays were to appraise the migratory and invasive capacities of RA-FLSs. Enzyme-linked immunosorbent assay (ELISA) and Western blot analysis were to estimate inflammatory response. In addition, MMP3 and MMP9 levels were also tested by ELISA analysis. After forkhead box M1 (FOXM1) was overexpressed, RND3 expression was detected by Western blot. The transcriptional relationship between FOXM1 and RND3 was predicted by HumanTFDB and JASPAR databases. Luciferase reporter and chromatin immunoprecipitation assays verified the binding ability of FOXM1 and RND3. The role of FOXM1/RND3 axis in RA was detected again by functional experiments. Western blot detected the expression of Rho/ROCK pathway-related proteins. RND3 expression was downregulated in RA. Overexpression of RND3 reduced the proliferation, migration, invasion, and inflammation of RA-FLSs. RND3 was inhibited by FOXM1 transcription, and upregulated FOXM1 reduced the inhibitory effect of RND3 overexpression on cell growth and inflammation, which might be associated with the Rho/ROCK pathway. RND3 transcriptionally regulated by FOXM1 inhibited the migration and inflammation of RA-FLSs in RA through the Rho/ROCK pathway.

Abstract
MATERIALS AND METHODS Active compounds of LJP were examined established on the analysis platform, Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. DrugBank identified drug targets and annotated them on UniPort and GeneCards. Besides, the COM-related genes were identified on GeneCards. The network of the drug, main active compounds, targets, and diseases was built utilizing Cytoscape. STRING was utilized to build the protein-protein interaction network. Moreover, the KEGG and GO pathway enrichment analysis were applied to analyze biological function. RESULTS 23 active compounds of LJP were screened, and 204 drug targets and 686 COM-related genes were identified. Forty-five intersection genes were overlapped from 204 drug targets and 686 COM-related genes. The drug-active compounds-target protein-diseases network was established based on 23 active compounds of LJP and 45 intersection genes. Moreover, the interaction of 45 intersection genes was explored by the PPI network, and the drug-active compounds-target protein-diseases network was formed grounded by 23 active compounds of LJP, 45 intersection genes, and PPI network. The KEGG and GO pathway enrichment analysis specified that 45 intersection genes primarily enriched in immune-related pathways and oxidative stress-related pathways. CONCLUSIONS In the research done, the main active compounds of LJP and drug targets in the treatment of COM were identified. Our findings might provide the ingredient option of LJP and drug targets of LJP in COM treatment.

Abstract
Introduction: Rheumatoid arthritis (RA) is an autoimmune disease that is identified with
chronic inflammation and progressive destruction of the joints. The
defective activity of regulatory T cells (Tregs) plays a crucial role in RA
development. Oleuropein (OLEU) is the most common polyphenolic compound in
olive leaf extracts with numerous pharmacological activities. In this study,
the potential effects of OLEU in shifting CD4+ T cells toward
Tregs are evaluated in patients with RA. Methods 32 healthy controls (HC) and 45 RA patients were included in two groups. The
immunoturbidometric technique was used to measure serum levels of c-reactive
protein (CRP) and rheumatoid factor (RF). Isolated CD4+ T cells
from peripheral blood mononuclear cells (PBMCs) of HC and RA patients were
cultured with appropriate concentrations of OLEU. The cytotoxicity effects
of OLEU were determined using the MTT assay at 24, 48, and 72 h. The
percentage of CD4+CD25 + FoxP3 regulatory T lymphocytes (Tregs)
and the expressions of IL-10 and TGF-β were evaluated by flow cytometry and
immunoassay techniques after treatment of cells with different
concentrations of OLEU for 24 h. The serum levels of RF and CRP in patients
with RA were 11.8 ± 5.32 IU/ml and 6.36 ± 5.82 mg/l, respectively. Results OLEU had a dose-dependent effect on the CD4+ T cells via
increasing the frequency of CD4+CD25 + FoxP3 Tregs
(p = 0.0001). Moreover, it induced the production of
IL-10 (p = 0.0001) and TGF-β (p < 0.01)
in both HC and RA patients. Conclusion The findings of this study suggest that OLEU may have immunomodulatory
effects by inducing Tregs, and it might help in developing a novel nutrition
strategy for management of autoimmune diseases such as RA.

Abstract
Laos has a rich plant diversity, and medicinal plants are used extensively in Lao traditional medicine for the treatment of a variety of human diseases. However, only a relatively small number of these plants have been investigated for their major components with potential antitumor, anti-infective, and other types of bioactivities. These species include Asparagus cochinchinensis, Diospyros quaesita, Gongronema napalense, Marsypopetalum modestum, Nauclea orientalis, Rourea minor, Stemona pierrei, and Stemona tuberosa. Thus far, the bioactive compounds isolated from these Lao plants include alkaloids, glycerol esters, phenolic compounds such as lignans and stilbenoids, steroids, and triterpenoids. Of these, the norlignan, nyasol (1b), the triterpenes, pyracrenic acid [3β-O-trans-caffeoylbetulinic acid (3)] and betulinic acid (3b), and the dimeric thiopyridine, dipyrithione (5), were found to show both cancer cell cytotoxicity and anti-infective activity. The present review focuses on examples of promising lead compounds isolated from Lao plants, with their possible development as potential therapeutic agents being discussed. It is hoped that this contribution will provide useful information on higher plants growing in Laos to help stimulate future discoveries of potential agents for the treatment of cancer, infections, and other diseases.

Abstract
Background: This study aimed to investigate the molecular mechanism of Radix Paeoniae Alba (white peony, WP) in treating immune inflammatory diseases of rheumatoid arthritis (RA) and tumor necrosis factor-alpha (TNF-α) inhibitors (TNFis) by using network pharmacology and molecular docking. Methods: In this study, the ingredient of WP and the potential inflammatory targets of RA were obtained from the Traditional Chinese Medicine Systematic Pharmacology Database, GeneCard, and OMIM databases, respectively. The establishment of the RA-WP-potential inflammatory target gene interaction network was accomplished using the STRING database. Network maps of the WP-RA-potential inflammatory target gene network were constructed using Cytoscape software. Gene ontology (GO) and the biological pathway (KEGG) enrichment analyses were used to further explore the RA mechanism and therapeutic effects of WP. Molecular docking technology was used to analyze the optimal effective components from WP for docking with TNF-α. Results: Thirteen active ingredients and 71 target genes were screened from WP, and 49 of the target genes intersected with RA target inflammatory genes and were considered potential therapeutic targets. Network pharmacological analysis showed that the WP active ingredients such as mairin, DPHCD, (+)-catechin, beta-sitosterol, paeoniflorin, sitosterol, and kaempferol showed better correlation with RA inflammatory target genes such as PGR, PTGS1, PTGS2, NR3C2, TNFSF15, and CHRM2, respectively. The immune-inflammatory signaling pathways of the active ingredients for the treatment of RA are the TNF-α signaling pathway, Toll-like receptor signaling pathway, cell apoptosis, interleukin-17 signaling pathway, C-type lectin receptor signaling pathway, mitogen-associated protein kinase, etc. Molecular docking results suggested that mairin was the most appropriate natural TNFis. Conclusion: Our findings provide an essential role and basis for further immune-inflammatory studies into the molecular mechanisms of WP and TNFis development in RA.
