Chem Biol Interact 2024; 387:110822. [PMID: 38056805 DOI: 10.1016/j.cbi.2023.110822] [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: 03/29/2023] [Revised: 05/06/2023] [Accepted: 11/27/2023] [Indexed: 12/08/2023]
Abstract
Rheumatoid arthritis (RA) is a highly prevalent and chronic inflammatory synovial joint disease manifested by hyperplasia and continuous inflammation. Curcumin (Cur) has been studied for alleviating RA. However, poor stability and oral bioavailability restrict its therapeutic value. Bisdemethoxycurcumin (BDMC), a curcumin (Cur) derivative, exerts better stability and oral bioavailability than Cur. However, the efficacy of BDMC on RA has not been fully clarified. The aim of the study was to investigate the therapeutic effects and underlying mechanisms of BDMC on RA. The in-vivo anti-arthritic activity of BDMC was determined via adjuvant-induced arthritis (AIA) rat model. Paw swelling, body weight, arthritic index, and histopathological assessments were performed. RAW264.7 cell was stimulated by lipopolysaccharides (LPS) in vitro. The cell viability were determined by CCK8 assay, while the migration ability was determined using cell wound healing and transwell assays. Furthermore, in-vivo and in-vitro levels of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) were assayed by ELISA, and that of IκBα, p-NF-κB, NF-κB, and COX-2 were assessed via Western blot or immunofluorescence. In AIA rat model, it suggested a higher anti-arthritic activity of BDMC than Cur, including amelioration of swelling in hind paws, reduced arthritic index, and alleviated histopathological injury in rats. Furthermore, BDMC also substantially decreased the levels of the aforementioned pro-inflammatory cytokines in both in-vivo and in-vitro, inhibited the IκBα degradation, down-regulated the COX-2 levels and p-NF-κB/NF-κB ratio in AIA rats and LPS-stimulated RAW264.7 cells. Additionally, BDMC showed an inhibitory effect on the migration of LPS-stimulated RAW264.7 cells. BDMC could effectively ameliorate RA by suppressing inflammatory reactions and inhibiting macrophage migration, more potentially than Cur.

Abstract
PURPOSE Patients submitted to radiotherapy (RT) may present in their healthy tissues surrounding the treated tumor, some typical acute inflammatory reactions induced by ionizing radiation (IR). The manifestation of inflammatory processes is a result of exacerbation of the immune system, as a response to radiation exposure, and this can be a limiting factor for RT protocols. To counteract this, some thiazolidinediones, such as LPSF/GQ-16, may be useful for modulating the patient's radioinduced inflammatory response in normal tissues. In this context, the present work aims to evaluate the activity of LPSF/GQ-16 on the levels of cytokines and the expression of the gene PPARγ in mononuclear cells irradiated in vitro, to analyze the immunomodulatory activity of the molecule and its action on radiomitigation. MATERIALS AND METHODS For this, blood samples from eight donors were collected and irradiated with 2 Gy, then the PBMC (peripheral blood mononuclear cells) were cultured and treated with LPSF/GQ-16. The levels of cytokines TNF-α, IFN-γ, IL-2 and IL-4 were quantified by CBA, while the genes of TNF-α, IFN-γ and PPARγ were analyzed by RT-PCR. RESULTS LPSF/GQ-16 significantly reduced the expression of proinflammatory cytokines (IFN-γ and TNF-α) in irradiated and nonirradiated groups. There was no significant reduction of anti-inflammatory cytokines (IL-2 and IL-4) by LPSF/GQ-16. The mRNA expression of PPAR-γ, IFN-γ and TNF-α in the presence of LPSF/GQ-16 was higher in the nonirradiated sample. CONCLUSION LPSF/GQ-16 showed effective activity after irradiation, with an important immunomodulatory activity in irradiated PBMCs.

Gao WJ, Liu JX, Xie Y, Luo P, Liu ZQ, Liu L, Zhou H. Suppression of macrophage migration by down-regulating Src/FAK/P130Cas activation contributed to the anti-inflammatory activity of sinomenine. Pharmacol Res 2021; 167:105513. [PMID: 33617975 DOI: 10.1016/j.phrs.2021.105513] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 02/18/2021] [Accepted: 02/18/2021] [Indexed: 01/01/2023]
Abstract
A large number of macrophages in inflamed sites not only amplify the severity of inflammatory responses but also contribute to the deleterious progression of many chronic inflammatory diseases, autoimmune diseases and cancers. Macrophage migration is a prerequisite for their entry into inflammatory sites and their participation of macrophages in the pathologic processes. Inhibition of macrophage migration is therefore a potential anti-inflammatory mechanism. Moreover, alleviation of inflammation also prevents the macrophages infiltration. Sinomenine (SIN) is an alkaloid derived from the Chinese medicinal plant Sinomenium acutum. It has multiple pharmacological effects, including anti-inflammation, immunosuppression, and anti-arthritis. However, its anti-inflammatory molecular mechanisms and effect on macrophage migration are not fully understood. The purpose of this research was to investigate the pharmacological effects and the molecular mechanism of SIN on macrophage migration in vivo and in vitro as well as to elucidate its anti-inflammatory mechanisms associated with macrophage migration. Our results showed that SIN reduced the number of RAW264.7 cells migrating into inflammatory paws and blocked lipopolysaccharide (LPS)-induced RAW264.7 cells and bone marrow-derived macrophages (BMDMs) migration in vitro. Furthermore, SIN attenuated the 3D mesenchymal migration of BMDMs. The absence of macrophage migration after circulatory and periphery macrophages depletion led to a reduction in the severity of inflammatory response. In macrophages depleted (macrophages-/-) mice, as inflammatory severity decreased, RAW264.7 cells migration was suppressed. A non-obvious effect of SIN on the inflammatory response was found in macrophages-/- mice, while the inhibitory effect of SIN on RAW264.7 cells migration was still observed. Furthermore, the migration of RAW264.7 cells pre-treated with SIN was suppressed in normal mice. Finally, Src/focal adhesion kinase (FAK)/P130Cas axis activation, which supports macrophages mesenchymal migration, and iNOS expression, NO production, integrin αV and in integrin β3 expressions, which promote Src/FAK/P130Cas activation, were down-regulated by SIN. However, SIN had no obvious effect on the expression of the monocyte chemoattractant protein-1 (MCP-1), which is an important chemokine for macrophage migration. These results indicated that SIN significantly inhibited macrophage mesenchymal migration by down-regulating on Src/FAK/P130Cas axis activation. There was a mutual regulatory correlation between the inflammatory response and macrophage migration, and the effects of SIN on macrophage migration were involved in its anti-inflammatory activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE A fruit of Ginkgo biloba L. also known as Ginkgo biloba, can be used for the treatment of cancer in Chinese traditional medicine. The scientific name of succulent skin, which is the episperm of Ginkgo nuts, is exocarp. Experiment shows that Ginkgo biloba exocarp extracts (GBEE) has the effects of immune promotion, cancer inhibition and etc. AIM OF STUDY Study on the activity of GBEE against Lewis lung cancer (LLC) angiogenesis and its partial molecular mechanism. MATERIALS AND METHODS The effect of GBEE on proliferation of LLC cells was detected by MTT method in vitro. The metastasis model of LLC was set up. The C57BL/6J mice were randomly separated into normal control, model control, positive control and GBEE (50, 100, 200mg/kg) treatment groups, n=10. The mice in normal group and model group were both intragastric gavage (i.g.) normal saline (NS) in a volume of 0.1mL/10g (b.w.), positive group were intraperitoneal (i.p.) injection cyclophosphamide (CPA) at a dose of 20mg/kg (b.w.) , the GBEE treatment groups were respectively i.g. GBEE 50, 100, and 200mg/kg (b.w.), once a day for 20d. After treatment, we calculated the tumor inhibition rate and anti-metastasis rate. The microvessel density (MVD) was measured by immunohistochemistry method in transplanted tumor. The expression levels of vascular en-dothelial growth factor (VEGF) and VEGFR2 mRNA or Wnt3a, β-catenin, VEGF, VEGFR2 and p-Akt/Akt protein expression were respectively tested by Quantitative Reverse transcription Polymerase chain reaction (qRT-PCR) or western blot in vitro and vivo. RESULTS GBEE suppressed the growth of LLC cells in a dose-dependent way at the dose of 5, 10, 20, 40, 80 and 160µg/mL in vitro. It can suppressed Wnt3a and β-catenin protein expression and the content of mRNA of VEGF and VEGFR2 in LLC cells significantly. In vivo, we discovered GBEE can retard the growth of LLC transplanted tumor in a dose-dependent way at the dose of 50, 100, 200mg/kg, suppressing tumor lung metastasis. The expression of CD34 was reduced, which means MVD was inhibited and so do β-catenin, VEGF, VEGFR2 and p-AKT/AKT protein expression and VEGF and VEGFR2 mRNA expression levels in LLC transplanted tumor of C57BL/6 mice. CONCLUSIONS GBEE played the effects of anti-tumor and anti-metastatic depending upon the inhibition of tumor angiogenesis, which may be closely relevant to its effect in blockage of Wnt /β-catenin-VEGF signaling pathway in LLC.

Abstract
Background Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease characterized by cellular infiltration into the joints, hyperproliferation of synovial cells and bone damage. Available treatments for RA only induce remission in around 30% of the patients, have important adverse effects and its use is limited by their high cost. Therefore, compounds that can control arthritis, with an acceptable safety profile and low production costs are still an unmet need. We have shown, in vitro, that celastrol inhibits both IL-1β and TNF, which play an important role in RA, and, in vivo, that celastrol has significant anti-inflammatory properties. Our main goal in this work was to test the effect of celastrol in the number of sublining CD68 macrophages (a biomarker of therapeutic response for novel RA treatments) and on the overall synovial tissue cellularity and joint structure in the adjuvant-induced rat model of arthritis (AIA). Methods Celastrol was administered to AIA rats both in the early (4 days after disease induction) and late (11 days after disease induction) phases of arthritis development. The inflammatory score, ankle perimeter and body weight were evaluated during treatment period. Rats were sacrificed after 22 days of disease progression and blood, internal organs and paw samples were collected for toxicological blood parameters and serum proinflammatory cytokine quantification, as well as histopathological and immunohistochemical evaluation, respectively. Results Here we report that celastrol significantly decreases the number of sublining CD68 macrophages and the overall synovial inflammatory cellularity, and halted joint destruction without side effects. Conclusions Our results validate celastrol as a promising compound for the treatment of arthritis.

Abstract
Macrophages play a crucial role in rheumatoid arthritis (RA). Their activation is the initial step of RA. This study was designed to detect the effects of total flavonoids from Litsea coreana Levl. (TFLC) on the complete Freund's adjuvant-induced (CFA-induced) arthritis (AA) in rats and to explore whether inflammatory cytokines were induced by the IRE1/mTORC1/TNF-α-dependant mechanism in peritoneal macrophages. In vivo, our data indicated that TFLC (100, 200 mg/kg, i.g. × 10 days) could significantly suppress secondary paw swelling and serum levels of TNF-α and IL-1β. Histopathological figures showed that TFLC treatment improved the morphologic changes of articular cartilages and synovium. Results of RT-PCR and western blotting demonstrated that TFLC suppressed expression of 78-KD glucose regulated protein (GRP78), X-box binding protein 1 (XBP1), mTOR complex 1 (mTORC1) and TNF-α in peritoneal macrophages of AA rats. Collectively, these results indicate that TFLC is able to ameliorate adjuvant-induced arthritis in a dose-dependent manner by suppressing the IRE1/mTORC1/TNF-α-regulated inflammatory response initiated in peritoneal macrophages.

Abstract
Our previous report has shown a natural pyranochalcones-derived compound, (E)-3-(3,4-Dimethoxyphenyl)-1-(5-hydroxy-2,2-dimethyl-2H-chromen-6-yl)prop-2-en-1-one (5b), that exerted protection against carrageenan-induced hind paw edema and adjuvant-induced arthritis. In this study, collagen-induced arthritis (CIA) model was used to further examine the anti-arthritic effects of 5b in vivo; the underlying molecular mechanisms of action were also investigated using a murine monocytic cell line, RAW264.7 cells. Here we showed that oral administration of 5b (20mg/kg) significantly suppressed the progression of arthritis. Improvement in disease severity was accompanied by inhibition of CD68-positive cells in knee joint and reduced pro-inflammatory cytokines TNF-α, IL-1β and IL-6 in serum. In vitro, 5b suppressed expressions of iNOS, cyclooxygenase-2 (COX-2), TNF-α, IL-6 and IL-1β as well as productions of nitric oxide (NO) and prostaglandin E2 (PGE2) in lipopolysaccharide (LPS)-treated macrophages. This compound also significantly suppressed LPS-induced NF-κB activation, including phosphorylation of I-κB, degradation of I-κB, and nuclear translocation of p65 and p50. Treatment with 5b also blocked LPS-induced expression of TLR4 remarkably, suppressed degradation of IRAKs and phosphorylations of JNK and ERK, but had little effect to p38 kinase activation. These findings indicated that 5b might be a therapeutic agent for rheumatoid arthritis, and exerted an anti-inflammatory effect mainly through mediating TLR4, NF-κB and ERK/JNK signaling pathways in monocytes.

Synthesis of a novel thiazolidinedione and evaluation of its modulatory effect on IFN- γ , IL-6, IL-17A, and IL-22 production in PBMCs from rheumatoid arthritis patients. BIOMED RESEARCH INTERNATIONAL 2013; 2013:926060.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease frequently characterized by chronic synovitis of multiple joints. The pathogenesis of RA is complex and involves many proinflammatory cytokines as Th17 related ones. PPAR γ is a nuclear receptor activator that represses proinflammatory gene expression. Thus, this work aimed to synthetize a new thiazolidinedione (TZD) analogue based on a well-known anti-inflammatory and PPAR γ agonist activity of this ring and evaluate its anti-inflammatory activity. After chemical structure confirmation, the compound named 5-(5-bromo-2-methoxy-benzylidene)-3-(2-nitro-benzyl)-thiazolidine-2,4-dione TM17 was submitted to cytokine releasing inhibition and PPAR γ genetic modulation assays. The new compound showed no toxicity on human and murine cells, decreasing IL-6 secretion by murine splenocytes and reducing IL-17A, IL-22, and IFN- γ expression in peripheral blood mononuclear cells from patients with RA. TM17 was more efficient in modulating the mRNA expression of PPAR γ than its well-used TZD agonist rosiglitazone. Surprisingly, TM17 was efficient on IL-17A and IFN- γ reduction, like the positive control methylprednisolone, and presented a better effect on IL-22 levels. In conclusion, PBMCs obtained from RA patients under TM17 treatment present a significant reduction in IL-17A, IL-22, and IFN- γ levels, but not IL-6 when compared with nontreated cells, as well as increase PPAR γ mRNA expression in absence of stimulus addressing it as a promising molecule in RA treatment.

Abstract
The promising activity shown by compounds containing thiazolidine-2,4-dione nucleus in numerous categories such as anti-hyperglycaemics, aldose reductase inhibitors, anti-cancer, anti-inflammatory, anti-arthritics, anti-microbials, etc. has made it an indispensable anchor for development of new therapeutic agents. Varied substituents on the thiazolidine-2,4-dione nucleus have provided a wide spectrum of biological activities. Importance of this nucleus in some activities like, peroxisome proliferator activated receptor γ (PPARγ) agonism and PPARγ-dependent and -independent anti-cancer activities are reviewed separately in literature. Short reviews on biological importance of this nucleus are also known in literature. However, owing to fast development of new drugs possessing thiazolidine-2,4-dione nucleus many research reports are generated in short span of time. So, there is a need to couple the latest information with the earlier information to understand the current status of thiazolidine-2,4-dione nucleus in medicinal chemistry research. In the present review, various derivatives of thiazolidine-2,4-diones with different pharmacological activities are described on the basis of substitution pattern around the nucleus combined with the docking studies performed in the active site of the corresponding receptors with an aim to help medicinal chemists for developing an SAR on thiazolidine-2,4-dione derived compounds for each activity. This discussion will further help in the development of novel thiazolidine-2,4-dione compounds.

Abstract
Acute liver failure (ALF) is a relatively rare liver disorder that leads to the massive death of hepatocytes. Our previous study reported that a novel small-molecule agent, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5'-methyl-7,7'-dimethoxy-4,4'-bibenzo[d][1,3]dioxole-5,5'-dicarboxylate (7k), possessed potent anti-inflammatory activity. In the present study, we further evaluated the therapeutic effects of 7k on lipopolysaccharide (LPS)-induced ALF and investigated the mechanisms of action. Our results demonstrated that 7k inhibited the migration of RAW264.7 macrophages, blocked the activity of nuclear factor-κB protein, and dose-dependently down-regulated the production of interleukin (IL)-1β, tumor necrosis factor-α, and IL-6 as well as their corresponding mRNAs in RAW264.7 cells. Oral administration of 7k at a dose of 50 mg/kg significantly suppressed the serum level of enzyme activity and prevented the damage of liver tissue in D-galactosamine/LPS-induced ALF. Treatment with 7k also remarkably blocked the increase in the number of CD11b(+)- and CD68(+)-positive cells in the liver, and in vivo nuclear factor-κB activity, known to regulate inflammatory responses in many cell types, was effectively inhibited. The serum concentrations and hepatic mRNA expression of proinflammatory cytokines tumor necrosis factor-α, IL-1β, and IL-6 were markedly down-regulated in mice by the treatment of 7k. In summary, 7k alleviated the development and progression of D-galactosamine/LPS-induced ALF by inhibiting macrophage infiltration and regulating the expression of cytokines.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fruit of Thladiantha dubia has been used in Chinese manchu nationality folk medicine for treatment of various pains, such as rheumatic pain, lumbocrural pain, and dysmenorrhea. The aim of the present study was to evaluate the anti-rheumatic effect of Thladiantha dubia fruit crude polysaccharide (TF-P) fraction in rats. MATERIALS AND METHODS TF-P was evaluated in mice for analgesic activity using acetic acid-induced abdominal contractions test and for anti-inflammatory activity using xylene-induced ear oedema model. Moreover, rheumatoid arthritis (RA) was induced by injection of CFA into the subplantar surface of the hind paw of the male Wistar rats. Joint swelling was measured. In order to evaluate the effect of TF-P on disease progression, proinflammatory mediators (TNF-α and IL-2), and antioxidant indicators (SOD, MDA, and NO) were determined in rats induced by CFA. Pathologic changes of RA in rats were also observed under light microscope. RESULTS AND CONCLUSIONS In the present study, TF-P at the dose of 200mg/kg (according to the clinical traditional dosage) significantly reduced writhings and stretchings induced by the acetic acid in mice. TF-P significantly inhibited xylene-induced ear oedema in mice, compared with control group. TF-P significantly inhibited inoculated and non-inoculated joint swellings in rats induced by CFA. TF-P had no effect of body weight in rats. The histopathological analysis suggested that TF-P obviously alleviated the degree of RA rats. TF-P treated rats preserved a nearly normal histological architecture of the joint. Results of the present study confirm the use of Thladiantha dubia traditionally for the treatment of painful and inflammatory conditions. Those results suggest TF-P has protective and therapeutic effects on RA rats induced by CFA.

Abstract
Taurochenodeoxycholic acid (TCDCA) is one of the main bioactive substances of animals' bile acid. In this study, we aimed to investigate the anti-arthritic effects and potential mechanism of TCDCA on adjuvant arthritis (AA) in rats. Freund's complete adjuvant (FCA) was used to induce AA in rats. Paw swelling, index of thymus and spleen and body weight growth rate were measured, and polyarthritis index and radiologic changes were observed. The production of TNF-α, IL-1β, IL-6 and IL-10 was detected by ELISA in serum and synoviocytes. mRNA expression of TNF-α, IL-1β, IL-6 and IL-10 was determined by real-time RT-PCR in synovium tissue and synoviocytes. In both prophylactic and therapeutic treatment, TCDCA significantly suppressed paw swelling and polyarthritis index, increased the loss body weight and index of thymus and spleen, and amended radiologic changes in AA rats. The overproduction and mRNA expression of TNF-α, IL-1β and IL-6 were remarkably suppressed in serum and synovium tissue of all TCDCA-treated rats, however, IL-10 was markedly increased in prophylactic treatment. In a definite concentration ranging from 300 μg/mL to 500 μg/mL, TCDCA showed marked inhibition in the overproduction and mRNA expression of TNF-α, IL-1β and IL-6 in synoviocytes in a concentration-dependent manner, but opposite action on IL-10. In conclusion, treatment with TCDCA confers a good anti-adjuvant arthritis activity in rats, which its reparative effects could be mediated via reduction of the protein and mRNA expression of TNF-α, IL-1β and IL-6, and augment of IL-10 in rats.

Abstract
SKLB010 is currently under development as a potential therapeutic agent for the treatment of acute hepatitis and rheumatoid arthritis. The purpose of this paper was to investigate the pre-clinical pharmacokinetics of SKLB010 in beagle dogs. An ultra performance liquid chromatographic tandem mass spectroscopy (UPLC-MS/MS) method was developed and validated for the quantitative determination of SKLB010 in dog plasma, using rosiglitazone as the internal standard (I.S.). Plasma samples were prepared by a simple solid phase extraction (SPE) method. The analyte and internal standard were separated by an Acquity UPLC BEH C18 (2.1 mm × 50 mm) column with a mobile phase of methanol-water (80/20, v/v) over 2 min. Detection was based on the multiple reaction monitoring with the precursor-to-product ion transitions m/z 234.10→147.92 (SKLB010) and m/z 356.15→150.00 (I.S.). The method was validated according to FDA guidelines on bio-analytical method validation. The selectivity, sensitivity, linearity, accuracy, precision, extraction recovery, ion suppression and stability were within the acceptable ranges. The method described above was successfully applied to reveal the single- and multi-pharmacokinetic profiles of SKLB010 in beagle dogs and should be extendable to pharmacokinetic studies in other species as well.
