Hallak M, Inal A, Baktir MA, Atasever A. Comparison of disease-modifying anti-rheumatic drugs and hyperbaric oxygen therapy in the experimental model of rheumatoid arthritis in rats. Clin Exp Pharmacol Physiol 2024; 51:e13906. [PMID: 38965677 DOI: 10.1111/1440-1681.13906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 05/07/2024] [Accepted: 06/03/2024] [Indexed: 07/06/2024]
Abstract
In this study, we wanted to investigate the effectiveness of combining disease-modifying anti-rheumatic drugs (DMARD) with hyperbaric oxygen therapy (HBOT) in reducing inflammation in a rheumatoid arthritis (RA) model using rats. We divided 56 male Sprague-Dawley rats into seven groups and induced RA using complete Freund's adjuvant. Some groups received HBOT, whereas others were given etanercept or leflunomide. We started the treatment on the 10th day after inducing RA and continued it for 18 days. To evaluate the effectiveness of the treatments, we measured paw swelling and used X-rays to examine the joints before and after the treatment. We also analysed the levels of two inflammatory markers, tumour necrosis factor (TNF)-α and interleukin (IL)-1β, using an enzyme-linked immunosorbent assay. Additionally, we conducted histological analysis and assessed the expressions of anti-IL-1β and anti-TNF-α antibodies. All the treatment groups showed a significant decrease in arthritis scores, paw swelling and levels of TNF-α and IL-1β. The X-ray images revealed improvements in joint structure, and the histopathological analysis showed reduced inflammation and collagen abnormalities. Combining DMARD with HBOT had similar effects to individual therapies, suggesting a cost-effective and potentially safer approach for improving outcomes in rats with RA.

Abstract
The monoterpene oxide, Eucalyptol (1,8-Cineole), a primary component of eucalyptus oil, has been evaluated pharmacologically for anti-inflammatory and analgesic activity. Current research aimed to evaluate Eucalyptol's anti-arthritic potential in a Complete Freund's adjuvant induced arthritis that resembles human rheumatoid arthritis. Polyarthritis developed after 0.1 mL CFA injection into the left hind footpad in rats. Oral administration of Eucalyptol at various doses (100, 200 and 400 mg/kg) significantly reduced paw edema, body weight loss, 5-LOX, PGE2 and Anti-CCP levels. Real-time PCR investigation showed significant downregulation of COX-2, TNF-α, NF-κB, IL-17, IL-6, IL-1β and upregulation of IL-4 and IL-10 in Eucalyptol treated groups. Hemoglobin and RBCs counts significantly increased post-treatment with Eucalyptol while ESR, CRP, WBCs and platelets count significantly decreased. Eucalyptol significantly increased Superoxide Dismutase, Catalase and Glutathione levels compared to CFA-induced arthritic control however, MDA significantly decreased post-treatment. Further, radiographic and histopathological examination of the ankle joints of rodents administered Eucalyptol revealed an improvement in the structure of the joints. Piroxicam was taken as standard. Furthermore, molecular docking findings supported the anti-arthritic efficacy of Eucalyptol exhibited high binding interaction against IL-17, TNF-α, IL-4, IL-10, iNOS NF-κB, 5-LOX, and COX-2. Eucalyptol has reduced the severity of CFA induced arthritis by promoting anti-inflammatory cytokines for example IL-4, IL-10 and by inhibiting pro-inflammatory cytokines such as 5-LOX, COX-2, IL-17, NF-κB, TNF-α, IL-6 and IL-1β. Therefore, Eucalyptol might be as a potential therapeutic agent because of its pronounced anti-oxidant and anti-arthritic activity.

Abstract
To investigate and compare efficacy as well as safety of Bacillus subtilis and dexamethasone (Dexa) in complete Freund's adjuvant (CFA)-induced arthritis, we used glucocorticoid monotherapy (Dexa 5 mg/kg/day) and B. subtilis (1 × 108 CFU/animal/day p.o) as pre-treatment and concurrent treatment for a duration of 35 days. Specific emphasis was on chronic aspect of this study since long-term use of Dexa is known to produce undesirable side effects. Treatment with Dexa significantly attenuated the arthritic symptoms but produced severe side effects like weight loss, increased mortality, immunosuppression, and altered histology of liver, kidney, and spleen. Oxidative stress was also elevated by Dexa in these organs which contributed to the damage. Treatment with B. subtilis improved symptoms of arthritis without producing any deleterious side effects as seen with Dexa therapy. Immunohistochemistry (IHC) profile revealed decreased expression of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukin (IL)-1β, tumor necrosis factor alpha (TNF-α), and increased nuclear factor erythroid 2-related factor 2 (Nrf-2) expression by B. subtilis and Dexa treatment in ankle joint of arthritic mice. Radiological scores were also improved by both treatments. This study concludes that B. subtilis could be an effective alternative for treating arthritis than Dexa since it does not produce life-threatening side effects on prolong treatment.

Abstract
Rheumatoid arthritis (RA) severely affects patients' quality of life and is commonly treated with glucocorticosteroids injections, like dexamethasone, which may have side effects. This study aimed to create a novel low dose of twin-drug hydrogel containing dexamethasone and diclofenac and explore its potential as a drug delivery system for an enhanced anti-inflammatory effect. Its characterization involved rheology, transmission electron microscope (TEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Furthermore, the hydrogel demonstrated thixotropic properties. The hydrogel exhibited no cytotoxicity against RAW 264.7 macrophages. Furthermore, the hydrogel demonstrated a significant anti-inflammatory efficacy by effectively downregulating the levels of NO, TNF-α, and IL-6 in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages. The co-delivery approach, when intra-articularly injected in adjuvant-induced arthritis (AIA) rats, significantly alleviated chronic inflammation leading to reduced synovitis, delayed bone erosion onset, and the downregulation of inflammatory cytokines. The biocompatibility and adverse effect evaluation indicated good biological safety. Furthermore, the hydrogel demonstrated efficacy in reducing NF-κB nuclear translocation in LPS-induced RAW 264.7 macrophages and inhibited p-NF-kB, COX-2, and iNOS expression both in RAW 264.7 macrophages and the joints of AIA rats. In conclusion, the findings indicate that the hydrogel possesses potent anti-inflammatory activity, which effectively addresses the limitations associated with free forms. It presents a promising therapeutic strategy for the management of RA.

Abstract
Homoisoflavone contains 16 carbon atoms in the skeleton. The homoisoflavonoid skeleton from natural products can be roughly divided into 13 kinds, among which 5 kinds of common skeletons contain a large amount of compounds and 8 kinds of abnormal skeletons comprise a small amount of compounds. In this article, the structure identification experience of homoisoflavonoids found in Caesalpinia mimosoides was used as references and an efficient 1H NMR spectroscopic method for identifying homoisoflavonoid structure has been established. Using the chemical shift differences of H-2, 3, 4 and 9, the common natural homoisoflavonoids can be quickly and conveniently determined.

Diversified cassane family diterpenoids from the leaves of Caesalpinia minax exerting anti-neuroinflammatory activity through suppressing MAPK and NF-κB pathways in BV-2 microglia. JOURNAL OF ETHNOPHARMACOLOGY 2023; 315:116653. [PMID: 37236383 DOI: 10.1016/j.jep.2023.116653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 05/13/2023] [Accepted: 05/15/2023] [Indexed: 05/28/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caesalpinia minax Hance, whose seeds are known as "Ku-shi-lian" in China, have been used in Chinese folk medicine for treatment of rheumatism, dysentery, and skin itching. However, the anti-neuroinflammatory constituents of its leaves and their mechanism are rarely reported. AIM OF THE STUDY To search for new anti-neuro-inflammatory compounds from the leaves of C. minax and elucidate their mechanism on anti-neuroinflammatory effect. MATERIALS AND METHODS The main metabolites of the ethyl acetate fraction from C. minax were analyzed and purified via HPLC and various column chromatography techniques. Their structures were elucidated on the basis of 1D and 2D NMR, HR-ESI-MS, and single crystal X-ray diffraction analysis. Anti-neuroinflammatory activity was evaluated in BV-2 microglia cells induced by LPS. The expression levels of molecules in NF-κB and MAPK signaling pathways were analyzed through western blotting. Meanwhile, the time- and dose-dependent expression of associated proteins such as iNOS and COX-2 were detected by western blotting. Furthermore, Compounds 1 and 3 were performed on the NF-κB p65 active site using molecular docking simulation to elucidate the molecular level inhibition mechanism. RESULTS 20 cassane diterpenoids, including two novel ones (caeminaxins A and B) were isolated from the leaves of C. minax Hance. Caeminaxins A and B possessed a rare unsaturated carbonyl moiety in their structures. Most of the metabolites exhibited potent inhibition effects with IC50 values ranging from 10.86 ± 0.82 to 32.55 ± 0.47μM. Among them, caeminaxin A inhibited seriously the expression of iNOS and COX-2 proteins and restrained the phosphorylation of MAPK and the activation of NF-κB signaling pathways in BV-2 cells. The anti-neuro-inflammatory mechanism of caeminaxin A has been studied systematically for the first time. Furthermore, biosynthesis pathways for compounds 1-20 were discussed. CONCLUSIONS The new cassane diterpenoid, caeminaxin A, alleviated the expression of iNOS and COX-2 protein and down-regulated of intracellular MAPK and NF-κB signaling pathways. The results implied that cassane diterpenoids had potential to be developed into therapeutic agents for neurodegenerative disorders such as Alzheimer's disease.

Abstract
Rheumatoid arthritis (RA) is an autoimmune chronic inflammatory disease associated with oxidative stress that causes excruciating pain, discomfort, and joint destruction. Ebselen (EB), a synthesized versatile organo-selenium compound, protects cells from reactive oxygen species (ROS)-induced injury by mimicking glutathione peroxidase (GPx) action. This study aimed to investigate the antioxidant and anti-inflammatory effects of EB in an arthritic irradiated model. This goal was achieved by subjecting adjuvant-induced arthritis (AIA) rats to fractionated whole body γ-irradiation (2 Gy/fraction once per week for 3 consecutive weeks, for a total dose of 6 Gy) and treating them with EB (20 mg/kg/day, p.o) or methotrexate (MTX; 0.05 mg/kg; twice/week, i.p) as a reference anti-RA drug. The arthritic clinical signs, oxidative stress and antioxidant biomarkers, inflammatory response, expression of NOD-like receptor protein-3 (NLRP-3) inflammasome, receptor activator of nuclear factor κB ligand (RANKL), nuclear factor-κB (NF-κB), apoptotic indicators (caspase 1 and caspase 3), cartilage integrity marker (collagen-II), and histopathological examination of ankle joints were assessed. EB notably improved the severity of arthritic clinical signs, alleviated joint histopathological lesions, modulated oxidative stress and inflammation in serum and synovium, as well as reduced NLRP-3, RANKL, and caspase3 expression while boosting collagen-II expression in the ankle joints of arthritic and arthritic irradiated rats with comparable potency to MTX. Our findings suggest that EB, through its antioxidant and anti-inflammatory properties, has anti-arthritic and radioprotective properties in an arthritic irradiated model.

Abstract
Photodynamic therapy (PDT) is a noninvasive technique that can be used to treat rheumatoid arthritis (RA) by irradiating photosensitizers with specific wavelengths of light to generate reactive oxygen species (ROS), thus leading to targeted cell necrosis. However, efficient delivery of photosensitizers with low side effects is a key issue. We developed a 5-aminolevulinic acid-loaded dissolving microneedle array (5-ALA@DMNA) that can locally and efficiently deliver photosensitizers for RA treatment by PDT. 5-ALA@DMNA was fabricated through a two-step molding process, which was characterized. The effects of 5-ALA-mediated PDT on RA fibroblast-like synoviocytes (RA-FLs) were investigated via in vitro experiments. Adjuvant arthritis rat models were established to evaluate the therapeutic effect of 5-ALA@DMNA-mediated PDT on RA. The results showed that 5-ALA@DMNA could penetrate the skin barrier and efficiently deliver photosensitizers. 5-ALA-mediated PDT can significantly inhibit the migration ability and selectively induce apoptosis of RA-FLs. Moreover, 5-ALA-mediated PDT had a significant therapeutic effect on rats with adjuvant arthritis, which may be related to the upregulation of interleukin (IL)- 4 and IL-10 and downregulation of TNF-α, IL-6, and IL-17. Thus, 5-ALA@DMNA-mediated PDT may be a potential therapy for RA.

Background Bone dysfunction is a crucial problem that occurs during rheumatoid arthritis (RA) disease. Osteoclast plays a significant role in bone resorption and osteoclast differentiation and its enhancement of bone destruction. Edaravone remarkably exhibited free radical scavenging and anti-inflammatory effects. The objective of the current investigation is to comfort the inhibitory effect of Edaravone (ED) against complete Freund adjuvant (CFA) rat model via inhibition of angiogenesis and inflammation. Methods Subcutaneous injection of CFA (1%) was used to induce arthritis; the rats were divided into different groups and received the oral administration of ED. Paw edema, body weight, and arthritis score were regularly estimated. Biochemical parameters were estimated, respectively. We also estimate the level of hypoxia-inducible factor-1α (HIF-1α), angiopoietin 1 (ANG-1), and vascular endothelial growth factor (VEGF). We also checked into how ED affected the differentiation of osteoclasts utilising a co-culture system with monocytes and synovial fibroblasts in arthritis rats. Results ED treatment significantly (P<0.001) suppressed the arthritis score and paw edema and improved the body weight. ED treatment significantly (P<0.001) altered the antioxidant parameters and pro-inflammatory cytokines: inflammatory mediator nuclear kappa B factor (NF-κB), cyclooxygenase-2 (COX-2), and prostaglandin E2 (PGE2), respectively. Furthermore, ED treatment significantly (P<0.001) suppressed the level of ANG-1, HIF-1α, and VEGF, respectively. The results suggest that ED suppressed osteoclast differentiation and also decreased the level of cytokines and osteopontin (OPN), receptor activator for nuclear factor-κ B Ligand (RANKL) and macrophage colony stimulating factor (M-CSF) in the co-culture supernatant of monocytes and synovial fibroblasts. Conclusion Edaravone could mitigate CFA via inhibiting angiogenesis and inflammatory reactions, which may be linked with the HIF-1α-VEGF-ANG-1 axis and also enhance the bone destruction of murine arthritis via suppression of osteoclast differentiation and inflammatory reaction.

RECENT ADVANCES IN INFLAMMATION & ALLERGY DRUG DISCOVERY 2023; 17:145-151.

Abstract
BACKGROUND The purpose of the present study was to study the potential anti-arthritic and antioxidant effects of trehalose in an experimental model of complete Freund's adjuvant (CFA)-induced arthritis. METHODS Arthritis was induced via subcutaneous injection of CFA (0.1) into the right footpad of each rat. Trehalose (10 mg/kg per day) and indomethacin (5 mg/kg) as a reference drug were intraperitoneally injected into CFA-induced arthritic rats from days 0 to 21. Changes in paw volume, pain responses, arthritic score, and oxidative/antioxidative parameters were determined. RESULTS Trehalose administration could significantly decrease arthritis scores (p <0.01) and paw edema (p <0.001), and significantly increase the nociceptive threshold (p <0.05) in CFA-induced arthritic rats. Trehalose also significantly reduced the pro-oxidant-antioxidant balance values when compared to CFA treatment alone. In addition, no significant difference was found between the trehalose group and indomethacin as a positive control group. CONCLUSION The current study suggests that trehalose has a protective effect against arthritis, which may be mediated by antioxidative effects of this disaccharide.

Abstract
A new strategy for the semisynthesis of the aromatic cassane-type diterpene taepeenin F (6) is reported. The introduction of the methyl group at C-14, characteristic of the target compound, was achieved via dienone 13, easily prepared from abietic acid (10), the major compound in renewable rosin. Biological assays of selected compounds are reported. The antiproliferative activity against HT29, B16-F10, and HepG2 tumor cell lines has been investigated. Salicylaldehyde 21 was the most active compound (IC50 = 7.72 μM). Products 16 and 21 displayed apoptotic effects in B16-F10 cells, with total apoptosis rates of 46 and 38.4%, respectively. This apoptotic process involves a significant arrest of the B16-F10 cell cycle, blocking the G0/G1 phase. Dienone 16 did not cause any loss of the mitochondrial membrane potential (MMP), while salicylaldehyde 21 caused a partial loss of the MMP. The anti-inflammatory activity of the selected compounds was investigated with the LPS-stimulated RAW 264.7 macrophages. All compounds showed potent NO inhibition, with percentages between 80 and 99% at subcytotoxic concentrations. Dienone 16 inhibited LPS-induced differentiation of RAW 264.7 cells, by increasing the proportion of cells in the S phase. In addition, salicylaldehyde 21 had effects on the cell cycle, recovering the cells from the G0/G1 full arrest produced in response to LPS action.

Concerted regulation of OPG/RANKL/ NF‑κB/MMP-13 trajectories contribute to ameliorative capability of prodigiosin and/or low dose γ-radiation against adjuvant- induced arthritis in rats. Int Immunopharmacol 2022; 111:109068. [PMID: 35944459 DOI: 10.1016/j.intimp.2022.109068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 07/08/2022] [Accepted: 07/14/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Prodigiosin (PDG) is a microbial red dye with antioxidant and anti-inflammatory properties, although its effect on rheumatoid arthritis (RA) remains uncertain. Also, multiple doses of low dose γ- radiation (LDR) have been observed to be as a successful intervention for RA. Thus, the purpose of this study was to investigate the ameliorative potential of PDG and/or LDR on adjuvant-induced arthritis (AIA) in rats. METHODS The anti-inflammatory and anti-arthritic effects of PDG and/or LDR were examined in vitro and in vivo, respectively. In the AIA model, the arthritic indexes, paw swelling degrees, body weight gain, and histopathological assessment in AIA rats were assayed. The impact of PDG (200 µg/kg; p.o) and/or LDR (0.5 Gy) on the levels of pro- and anti-inflammatory cytokines (IL-1β, TNF-α, IL-6, IL-18, IL-17A, and IL-10) as well as the regulation of osteoprotegrin (OPG)/ receptor activator of nuclear factor κB ligand (RANKL)/ nuclear factor-κB (NF-κB)/MMP-13 pathways was determined. Methotrexate (MTX; 0.05 mg/kg; twice/week, i.p) was administered concurrently as a standard anti-arthritic drug. RESULTS PDG and/or LDR markedly diminished the arthritic indexes, paw edema, weigh loss in AIA rats, alleviated the pathological alterations in joints, reduced the levels of pro-inflammatory cytokines IL-1β, TNF-α, IL-6, IL-18, IL-17A, and RANKL in serum and synovial tissues, while increasing anti-inflammatory cytokines IL-10 and OPG levels. Moreover, PDG and/or LDR down-regulated the expression of RANKL, NF-κBp65, MMP13, caspase-3, and decreased the RANKL/OPG ratio, whereas OPG and collagen II were enhanced in synovial tissues. CONCLUSION PDG and/or LDR exhibited obvious anti-RA activity on AIA.

Abstract
Pharmacological studies revealed that cedrol, a natural sesquiterpene, has antioxidant, anti-inflammatory, and analgesic properties. This study is aimed at evaluating the potential antiarthritic activity of cedrol in a rat experimental model of arthritis induced by using complete Freund's adjuvant (CFA). Arthritis was induced in Wistar rats by CFA (0.1 ml) injection. Cedrol (10 and 20 mg/kg) and indomethacin (5 mg/kg) were orally administered from day one and continued for 21 days. The antiarthritic activity was assessed through mechanical allodynia and thermal hyperalgesia responses, paw edema assessment, and arthritis scores. Serum TNF-α and IL-1β levels were measured for the evaluation of inflammation. Furthermore, serum oxidative stress markers, including malondialdehyde (MDA) and thiol levels, as well as superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, were also assessed. Oral administration of cedrol and indomethacin significantly decreased paw edema and arthritis score. Besides, cedrol and indomethacin significantly decreased pain responses. In the serum of the CFA group, TNF-α, IL-1β, and MDA were higher, while thiol and SOD and GPx were lower than the control group. Treatment by cedrol and indomethacin corrected the biochemical parameters in the serum. In this study, cedrol offers potential antiarthritic properties through its anti-inflammatory and antioxidant effects.

Activities and Molecular Mechanisms of Diterpenes, Diterpenoids, and Their Derivatives in Rheumatoid Arthritis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4787643. [PMID: 35368757 PMCID: PMC8975657 DOI: 10.1155/2022/4787643] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/11/2021] [Accepted: 02/02/2022] [Indexed: 12/11/2022]
Abstract
Diterpenes and their derivatives have many biological activities, including anti-inflammatory and immunomodulatory effects. To date, several diterpenes, diterpenoids, and their laboratory-derived products have been demonstrated for antiarthritic activities. This study summarizes the literature about diterpenes and their derivatives acting against rheumatoid arthritis (RA) depending on the database reports until 31 August 2021. For this, we have conducted an extensive search in databases such as PubMed, Science Direct, Google Scholar, and Clinicaltrials.gov using specific relevant keywords. The search yielded 2708 published records, among which 48 have been included in this study. The findings offer several potential diterpenes and their derivatives as anti-RA in various test models. Among the diterpenes and their derivatives, andrographolide, triptolide, and tanshinone IIA have been found to exhibit anti-RA activity through diverse pathways. In addition, some important derivatives of triptolide and tanshinone IIA have also been shown to have anti-RA effects. Overall, findings suggest that these substances could reduce arthritis score, downregulate oxidative, proinflammatory, and inflammatory biomarkers, modulate various arthritis pathways, and improve joint destruction and clinical arthritic conditions, signs, symptoms, and physical functions in humans and numerous experimental animals, mainly through cytokine and chemokine as well as several physiological protein interaction pathways. Taken all together, diterpenes, diterpenoids, and their derivatives may be promising tools for RA management.

Co-treatment of Nimbolide augmented the anti-arthritic effects of methotrexate while protecting against organ toxicities. Life Sci 2022; 295:120372.

Abstract
Prolonged exposure to the pharmacological doses of disease-modifying anti-rheumatic drugs (DMARDs) often results in major organ toxicities resulting in poor patient compliance. Methotrexate (MTX) is one of the commonly prescribed DMARDs for the treatment of arthritis, which results in vital organ dysfunction. To retain the anti-arthritic activity of MTX with the reduction in toxicities, combination therapies are warranted. Nimbolide (NMB) is a potent anticancer, anti-inflammatory and anti-fibrotic agent whose potential has been demonstrated in various pre-clinical models. Monoarthritis was developed with Complete Freund's Adjuvant in the knees of Wistar rats and treatment was given with either NMB (3 mg/kg/day) or MTX (2 mg/kg/week) alone or combination therapy (NMB + MTX). The anti-arthritic effects were evaluated by arthritic scoring, radiological imaging, synovial tissue proteins analysis, and histopathological staining. While hepato-renal toxicity was assessed in serum by evaluating the kidney and liver functional parameters, in tissues by oxidative-nitrosative stress markers, and pro-inflammatory cytokines levels. Histopathological analysis was performed to study the extent of tissue damage. Molecular studies like immunoblotting and immunohistochemistry were performed to understand the effect of combination therapy. We thereby report that monotherapy with either NMB or MTX exhibited significant anti-arthritic effects, while combination therapy resulted in augmented anti-arthritic effects with significant reduction in hepato-renal toxicity produced by MTX probably through anti-inflammatory and anti-oxidant effects. Therefore, our proposed combination of NMB and MTX may serve as a potential strategy for the effective management of arthritis.

Abstract
The main aim of this research was to design a MCL-1 siRNA and dexamethasone (DEX)-loaded folate modified poly(lactide-co-glycolide) (PLGA)-based polymeric micelles with an eventual goal to improve the therapeutic outcome in the rheumatoid arthritis (RA). Polymeric micelles encapsulating the MCL-1 siRNA and DEX was successfully developed and observed to be stable. Physicochemical characteristics such as particle size and particle morphology were ideal for the systemic administration. Folate-conjugated DEX/siRNA-loaded polymeric micelles (DS-FPM) significantly lowered the MCL-1 mRNA expression compared to either DEX/siRNA-loaded polymeric micelles (DS-PM) or free siRNA in Raw264.7 cells and macrophage cells suggesting the importance of targeted nanocarriers. Most importantly, DS-FPM exhibited a greatest decrease in the hind paw volume with lowest clinical score compared to any other treated group indicating a superior anti-inflammatory activity. DS-FPM showed significantly lower levels of the TNF-α and IL-1β compared to AIA model and free groups. The folate receptor (FR)-targeting property of DS-FPM has been demonstrated to be a promising delivery platform for the effective delivery of combination therapeutics (siRNA and DEX) toward the treatment of rheumatoid arthritis.

Abstract
Eighteen cassane diterpenoids, including five new lactam-type (4-8), 12 new lactone-type (1-3 and 9-17), and one known compound (18), were isolated from Caesalpinia sinensis. To our knowledge, this is the first study on the seed kernels of C. sinensis, and cassane derivatives were discovered in this plant for the first time. Their structures including absolute configurations were established by extensive spectroscopic methods complemented with single-crystal X-ray diffraction analyses and ECD calculations. Compounds 4-8 were identified as a group of rare cassane diterpenoids possessing a lactam D-ring instead of a typical lactone moiety. Biological evaluation revealed that compounds 4-6 exhibited effective inhibitory effects on NO production in the LPS-induced RAW 264.7 macrophages, with IC50 values in the range 8.2-11.2 μM. Compound 4 suppressed the excessive production of NO by down-regulating the expression of inducible nitric oxide synthase enzymes (iNOS) and reducing the enzymatic activity of iNOS. Moreover, the intermolecular interaction and binding mode between compound 4 and iNOS were elaborated by conducting a molecular docking study.

Yang L, Liu R, Fan A, Zhao J, Zhang Y, He J. Chemical Composition of Pterospermum heterophyllum Root and its Anti-Arthritis Effect on Adjuvant-Induced Arthritis in Rats via Modulation of Inflammatory Responses. Front Pharmacol 2020; 11:584849. [PMID: 33362544 PMCID: PMC7759541 DOI: 10.3389/fphar.2020.584849] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 10/14/2020] [Indexed: 12/17/2022] Open
Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease without effective and beneficial drugs. Many traditional folk medicines have been proven to be effective in treating RA. Among these, the root of Pterospermum heterophyllum Hance has been widely used as a traditional remedy against RA in China, but there is no scientific basis yet. The aim of this study was to investigate for the first time the chemical compositions and therapeutic effect of P. heterophyllum on adjuvant-induced arthritis (AIA) model in rats. 73 compounds were identified from P. heterophyllum based on ultra-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-qTOF-MS/MS), and flavonoids may be partly responsible for the major anti-arthritic effect. In parallel, the P. heterophyllum extract at 160, 320, and 640 mg/kg/day were orally administered to rats for 22 days after post-administration adjuvant. The results showed that P. heterophyllum remarkably ameliorated histological lesions of the knee joint, increased body weight growth, decreased arthritis score, reduced thymus and spleen indices in model rats. Moreover, P. heterophyllum treatment persuasively downregulated the levels of rheumatoid factor (RF), C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), IL-6, IL-17, cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX) and matrix metalloproteinase-2 (MMP-2), and observably upregulated IL-4 and IL-10 levels in model rats. These findings suggest that P. heterophyllum has a prominent anti-RA effect on AIA rats by modulating the inflammatory responses, and supports the traditional folk use of this plant.

The Activity Screening of Hmong Herbs Caesalpiniaminax and an Antitumor Effect Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:3585736. [PMID: 33163082 PMCID: PMC7605935 DOI: 10.1155/2020/3585736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Revised: 08/17/2020] [Accepted: 09/16/2020] [Indexed: 11/17/2022]
Abstract
Aim To screen active sites from roots, stems, and leaves of Caesalpinia minax and study its antitumor effect. Methods Human liver cancer HuH-7 cells were used to screen the active sites of C. minax by MTT assay, and the polar extracts were analyzed by high-performance liquid chromatography (HPLC). The medicated serum prepared from rats was used to investigate the effect on the proliferation of Hepa 1-6 mouse hepatoma cells. The H22 hepatoma-bearing mice model was established and treated with the petroleum ether extract of stems and leaves (HY②) by intraperitoneal injection (20, 60 mg·kg-1) and intragastric (100, 300 mg·kg-1) for 12 days. Results The petroleum ether extracts were the effective active site. The IC50 value of the petroleum ether extract of stems and leaves (HY②) was 58.9 μg·ml-1, and that of the roots (HG②) was 46.79 μg·ml-1. The grey relational analysis cleared that the 11 common peaks of the active extracts had a close correlation with the antitumor activity. The medicated serum prepared by ip. administration had a significant inhibitory effect on the Hepa1-6 cells, but it had no inhibitory effect by intragastric administration. High-dose administration significantly reduced tumor size in H22 hepatoma-bearing mice, and the tumor inhibition rates were 64.47% and 53.41%. Necrosis of tumor cells, infiltration of inflammatory cells, and fibrous tissue proliferation were promoted, and the expression of the proliferating cell nuclear antigen (PCNA) and vascular endothelial growth factor (VEGF) was reduced compared with the control group. Conclusion The petroleum ether extract of C. minax had a significant antitumor activity. An immunohistochemical study showed that, through inhibiting the expression of the VEGF and growth of the tumor blood vessel, the proliferation of tumor cell and expression of PCNA can be inhibited.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease mainly characterized by chronic polyarthritis. Many types of cells play pivotal roles in the pathogenicity of RA, such as T cells, B cells, macrophages, dendritic cells (DCs), osteoclasts (OCs), and fibroblast-like synoviocytes (FLS). Tripterygium wilfordii Hook f. (TwHf) and its ingredients are able to control disease activity by regulating the functions of cells mentioned above, and the clinical studies have highlighted the importance of TwHf ingredients in RA treatment. They have been demonstrated to improve the RA symptoms of animal models and patients. In this review, we discussed the effect of TwHf ingredients on pathogenicity cells, including disease/cell phenotypes and molecular mechanisms. Here, we constructed a cell-cell interaction network to visualize the effect of TwHf ingredients. We found that TwHf ingredients could inhibit the differentiation and proliferation of the pathogenicity cells. Besides, the components could decrease the levels of pathogenicity cytokines [i.e., interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α)]. Many signaling pathways are involved in the underlying mechanisms, such as PI3K, NF-κB, and MAPK signaling pathways.

Abstract
Tripterygium wilfordii Hook.f and Tripterygium hypoglaucum (H.Lév.) Hutch is effective herbs to prevent aggravation of Rheumatoid arthritis (RA). However, both of them show severe side effects in the reproductive system and other systems. Kunxian Capsule (KX), a Traditional Chinese Medicine (TCM) patent prescription, comprised of 4 herbs, including H.Lév. Hutch, is reported to be an available prescription in treating RA with fewer side effects as compares to Tripterygium tablets. To reveal the pharmacological mechanism of KX in RA treatment and side effect alleviation, we collected related information of KX from open-access databases and performed various analyses. 1354 targets were identified in KX. These targets were enriched in the calcium signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway and PI3K-AKT signaling pathway, forming biological functions, such as cofactor binding, coenzyme binding, etc. These pathways or functions mostly affect cell cycle, differentiation, and maturation of Th17 cells, macrophage, and synovial fibroblast. These targets also act on the IL-17 signaling pathway, Th17 cell differentiation signaling pathway and TNF signaling pathway, which is related to inflammation response inhibition. Next, a disease network was constructed, which indicated IMPDH2, MTHFD1 are the key genes answering for the side effects of H.Lév. Hutch. The side effect–related genes lead to the negative regulation of nucleic acid, which could be restored by the rest 3 herbs through some positive amino acid metabolism. In conclusion, KX is a relatively safe alternative approach in RA intervention.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 249:112394. [PMID: 31734448 DOI: 10.1016/j.jep.2019.112394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Revised: 07/14/2019] [Accepted: 11/12/2019] [Indexed: 05/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants selected for this study, Stereospermum colais and Stereospermum suaveolens are named as Patala in Ayurvedic medicine. Patala is a component of the reputed dasamula (ten roots) used for various imperative Ayurvedic formulations. The roots of Patala have rich traditional value especially in the treatment of inflammation and rheumatism. Nevertheless no methodical study has been consummated in these plants. Consequently, an endeavor to ascertain the anti-arthritic potential of the two plants was made besides to impart the fact with regards to the supreme one. AIM OF THE STUDY The aim of the study is to evaluate the anti-arthritic potential of Stereospermum colais and Stereospermum suaveolens using Complete Freund's Adjuvant induced arthritic model. MATERIALS AND METHODS The freshly collected root material of Stereospermum colais (SC) and Stereospermum suaveolens (SS) were successively extracted with solvents such as petroleum ether, chloroform, ethyl acetate and ethanol by cold maceration and the ethanolic extract of Stereospermum colais (EESC) and Stereospermum suaveolens (EESS) were standardized using lapachol as standard. The extracts were further subjected to acute oral toxicity and in vivo anti-arthritic evaluation by Complete Freund's Adjuvant induced arthritic model using methotrexate as standard. Body weight changes, reduction in paw volume, biochemical, histopathological and the expression of Cluster of differentiation 4 cells, inflammatory cytokines such as Tumor necrosis factor-α, Interleukin-2 and Tranforming growth factor-β through immunohistochemical analysis were studied to access the anti-arthritic potential. RESULTS AND CONCLUSION s: The Extracts EESC and EESC were standardized using lapachol by HPLC method and the amount was found to 3.9% w/w and 0.9% w/w respectively. The LD50 of the tested extracts EESC and EESS were found to be greater than 2000 mg/kg b.w through acute oral toxicity study. The extracts EESC (58.97%) and EESS (20.51%) were significantly reduced the paw volume in a dose dependent manner. The reduction in the paw volume exhibited the anti-inflammatory potential of the ethanolic extract of both the plants. The extracts at the dose of 400 mg/kg has markedly inhibited the change in joint architecture as compared to arthritic control. Also the study revealed that the extracts may possibly act by affecting the T cell mediated inflammatory process which was evident by decreased expression of Cluster of Differentiation 4 cells, Interleukin-2 and Tumor necrosis factor-α. The Extracts were found to have rich phytochemicals such as terpenoids, flavonoids, quinones, phenols and tannins may probably attribute to the anti-arthritic property of the plants. The lapachol a naphthaquinone present in both the extracts also contributed for its property. The study concludes that ethanolic extract of both the plants (EESC and EESS) exhibited significant anti-arthritic activity and Stereospermum colais was found to be more potent than Stereospermum suaveolens which corroborates the traditional use of roots of Stereospermum colais and Stereospermum suaveolens in the treatment of arthritis.

N-Butanol Extract of Gastrodia elata Suppresses Inflammatory Responses in Lipopolysaccharide-Stimulated Macrophages and Complete Freund's Adjuvant- (CFA-) Induced Arthritis Rats via Inhibition of MAPK Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:1658618. [PMID: 32063980 PMCID: PMC6996701 DOI: 10.1155/2020/1658618] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2019] [Revised: 12/16/2019] [Accepted: 12/26/2019] [Indexed: 12/16/2022]
Abstract
Gastrodia elata is a traditional herbal medicine that has been used for centuries to treat rheumatism. Previous studies have confirmed that ethanol extracts of Gastrodia elata have anti-inflammatory and antioxidant activities, and the n-butanol fraction exerts a higher inhibitory effect. However, the in vivo anti-inflammatory effects of Gastrodia elata have not been evaluated. Thus, we assessed the therapeutic effect of the n-butanol extract of Gastrodia elata (BGE) on complete Freund's adjuvant- (CFA-) induced arthritis rats which were separated into six groups (NOR; MODEL; CFA + dexamethasone (DEX); CFA + 25, 50, 100 mg/kg BGE). The paw swelling, joint radiology, and histology were used to analyze the effect of BGE on delaying the progression of rheumatoid arthritis. Furthermore, serum levels of inflammatory cytokines were analyzed via ELISA. In addition, the effect of BGE on nitric oxide (NO) production, expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2(COX-2), and inflammatory cytokines were detected in lipopolysaccharide- (LPS-) stimulated RAW264.7 macrophage cells. Lastly, the impacts of BGE on the activation of the mitogen-activated protein kinases (MAPK) pathway in CFA rats and LPS-stimulated RAW264.7 macrophage were examined by western blot analysis. The results show that BGE can significantly reduce paw swelling without losing the body weight of rats. Imaging assessment confirms that BGE can protect cartilage from destruction, as well as reducing inflammatory cell infiltration and synovial proliferation. Moreover, BGE suppresses the production of inflammatory cytokines in serum and inhibits the activation of the phosphorylation of p38 and ERK in CFA rats. BGE was also demonstrated to decrease the production of NO and inflammatory cytokines in LPS-stimulated RAW264.7 cells. The effect of BGE in LPS-induced expression leads to reduced p38 and ERK phosphorylation and also downregulates the protein expression of iNOS and COX-2. Taken together, BGE exhibits a potential therapeutic effect on CFA rats, and its anti-inflammatory and antioxidant effects were possibly exerted by regulation of ERK/p38MAPK.

Baihu Jia Guizhi Decoction Improves Rheumatoid Arthritis Inflammation by Regulating Succinate/SUCNR1 Metabolic Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3258572. [PMID: 31949465 PMCID: PMC6948314 DOI: 10.1155/2019/3258572] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 11/04/2019] [Accepted: 11/26/2019] [Indexed: 12/29/2022]
Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis. Succinate is an inflammatory metabolic signal that exacerbates RA synovitis by activating succinate receptor 1 (SUCNR1) to amplify the release of IL-1β. Thus, inhibition of succinate activation of SUCRN1 could be an effective method to inhibit the inflammation of RA. Baihu Jia Guizhi decoction (BHGZ), which is composed of Gypsum Fibrosum, Anemarrhena asphodeloides Bge., Cinnamomum cassia Presl., Glycyrrhiza uralensis Fisch., and Oryza sativa L., is a Traditional Chinese Medicine (TCM) prescription used to treat RA in clinic. In addition, TCM believes that damp and heat environment is one of the causes of RA. In this study, we tested the role of damp and heat environments in exacerbating RA inflammation and the anti-inflammatory effect of BHGZ, based on succinate/SUCNR1/IL-1β pathway in the adjuvant arthritis (AA) model with damp and heat environment (AA + DHE). Results showed that paw swelling and synovial pathology were significantly increased in AA rats, and these results were aggravated by stimulation in damp and heat environment. BHGZ improved AA + DHE rats' paw swelling, synovial hyperplasia, and inflammatory cell infiltration and reduced IL-1β. In addition, AA rats significantly increased the expression of SUCNR1, and the stimulation of damp and heat environment not only increased the expression of SUCNR1 but also promoted the accumulation of succinate. BHGZ simultaneously reduced the concentration of succinate and the expression of SUCNR1. Finally, SDH activity was decreased in AA rats and AA + DHE rats, while BHGZ increased SDH activity and then reduced succinate concentration. Therefore, we prove that damp and heat environment deteriorated the inflammation of RA which is the activation of succinate/SUCNR1 pathway, while BHGZ regulates SDH activity to reduce the accumulation of succinate and inhibit the activation of SUCNR1 that is the underlying mechanism of its treatment of RA.

Abstract
We performed 16S rDNA sequencing of tilapia fecal samples to analyze changes in tilapia gut contents after cultivation of the fish in the presence of sandwich-like floating beds of Chinese medicinal herbs (5 and 10% planting-areas; 5% Polygonum cuspidatum). The interactive effects between water quality and blood and hepatic pro- and anti-inflammatory concentrations were also assessed. Our results showed that the water quality (i.e., NO3--N, NO2--N, TP removal rates) improved, and the abundance of Chloroflexi and Cyanobacteria increased. The abundance of Bacteroidetes, Verrucomicrobia, Saccharibacteria, and Actinobacteria showed both significant seasonal decreases and increases in the presence of P. cuspidatum (increases in August and decreases in July). Fish blood and hepatic IL-10 and IFN-γ levels (together with fish sampled in September) significantly increased in the P. cuspidatum group sampled in August, while those of TNF-α (10% sandwich-like, P. cuspidatum), IL-1β (P. cuspidatum), IL-8 (5% sandwich-like in September, S905S) significantly decreased. Heat shock proteins 60 and 70 levels significantly increased in the P. cuspidatum group, and complement C3 and C4 concentrations significantly increased in S905S. This study demonstrated that enhanced immunity through the regulation of pro- and anti-inflammatory proteins was sustained throughout development until harvest, particularly in fish grown with P. cuspidatum.

Abstract
Cassane diterpenoids (CA) are considered as the main active constituents of medicinal plants belonging to the Caesalpinia genus. Three cassane derivatives, bonducellpin G (BG), 7-O-acetyl-bonducellpin C (7-O-AC) and caesalmin E (CE), isolated from Caesalpinia minax Hance seeds, showed strong anti-inflammatory activity. In this paper, pharmacokinetics (BG, 7-O-AC, CE) and tissue distribution (7-O-AC, CE) properties were studied for the first time using a reliable, sensitive and rapid UHPLC-Q-Orbitrap HR-MS to develop new anti-inflammatory agents. A novel quantitative method with full scan in positive ion mode was used to determine the contents of compounds. They were separated using acetonitrile-water (0.1% formic acid) as gradient mobile phase. The calibration curve displayed good linearity and the lower limit of quantitation was 0.005-0.02 μg/mL for all analytes. Meanwhile, the absorption, distribution, metabolism, excretion (ADME) property was predicted using PreADMET web. The pharmacokinetic parameters indicated that they were absorbed quickly, eliminated rapidly together with high blood concentration. The results of tissue distribution demonstrated that CE was distributed rapidly and widely among tissues, and stomach was the main tissue site of CE and 7-O-AC, followed by small intestine/liver. This study indicates that the structures and dosages of active CA should be modified to help improve the absorption rate and residence time, and the findings are helpful for the pharmaceutical design of CA derivatives.

Abstract
BACKGROUND Quillaja saponaria Mol. bark contains a high concentration of triterpene saponins that have been used for centuries as a cleansing, antiinflammatory and analgesic agent in Chilean folk medicine. In earlier studies, in mice, both the anti-inflammatory as well as the antinociceptive effect of the major sapogenin, quillaic acid have been demonstrated (QA). OBJECTIVE To determine the antihyperalgesic effect of QA one and seven days after itpl administration of complete Freund's adjuvant (CFA) in male mice using the hot plate test in the presence of complete Freund's adjuvant (HP/CFA) as an acute and chronic skeletal muscle pain model. METHODS The present study evaluated the antihyperalgesic activity of QA against acute and chronic skeletal muscle pain models in mice using the hot plate test in the presence of complete Freund's adjuvant (HP/CFA), at 24 h (acute assay) and 7 days (chronic assay) , with dexketoprofen (DEX) as the reference drug. RESULTS In acute and chronic skeletal muscle pain assays, QA at 30 mg/kg ip elicited its maximal antihyperalgesic effects (65.0% and 53.4%) at 24 h and 7 days, respectively. The maximal effect of DEX (99.0 and 94.1 at 24 h and 7 days, respectively) was induced at 100 mg/kg. CONCLUSION QA and DEX elicit dose-dependent antihyperalgesic effects against acute and chronic skeletal muscle pain, but QA is more potent than DEX in the early and late periods of inflammatory pain induced by CFA.
