Abstract
BACKGROUND Triptolide (TP) has been confirmed to possess many beneficial functions including anti-inflammation and immunosuppression. OBJECTIVE The present study aimed to explore the potential involvement of IL-2/IL-2R pathway in the immunosuppressive activities of TP. METHODS Cultured CTLL-2 cells were utilized to evaluate the potential benefits of TP. Then cell viability was determined by CCK-8 assay, IFN-γ level by ELISA assay, Annexin V-FITC/PI double-staining and CD25 expression by flow cytometry, and protein expression by western blotting. Additionally, rhIL-2-driven lymphocytes following ConA activation were investigated. The interactions of TP with IL-2 and IL-2Rα were investigated by binding assays and molecular dynamics simulations. RESULTS TP treatment attenuated IFN-γ level and cell viability in both rhIL-2-induced CTLL-2 cells and rhIL-2-driven splenic lymphocytes. TP treatment increased cellular apoptosis/necrosis and cleaved PARP-1 level, while suppressed c-Myc level in rhIL-2-induced CTLL-2 cells. Additionally, TP treatment reduced CD25 expression on CTLL-2 cell surface. Notably, the phosphorylation protein levels in IL-2R signaling pathways were inhibited by TP exposure prior to rhIL-2 stimulation. SPR and BLI assays verified TP that directly bound to rhIL-2 and rmIL-2Rα, respectively. Molecular simulations suggested that TP bound at the interface of IL-2 and IL-2Rα near the hydrophobic patch composed of F62, L92 on IL-2 and L23, I46, V139 on IL-2Rα, resulting in decreased binding free energy between IL-2 and IL-2Rα. CONCLUSIONS These findings collectively emphasized that TP interfered IL-2/IL-2Rα interactions, down-regulated IL-2Rα expression, and inhibited IL-2R signaling pathways activation, thereby leading to the immune cells being desensitized to rhIL-2 and exhibiting immunosuppressive properties.

Hybrid derivatives containing dimethyl fumarate and benzothiazole scaffolds for the potential treatment of multiple sclerosis; in silico & in vivo study. Daru 2024:10.1007/s40199-024-00529-8. [PMID: 39106020 DOI: 10.1007/s40199-024-00529-8] [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: 11/12/2022] [Accepted: 06/30/2024] [Indexed: 08/07/2024] Open
Abstract
BACKGROUND Multiple Sclerosis (MS) is a chronic autoimmune, inflammatory neurological disease of the CNS. Riluzole and dimethyl fumarate (DMF) are two FDA-approved drugs to treat amyotrophic lateral sclerosis (ALS) and MS. Riluzole (a benzothiazole derivative) inhibits glutamate release from nerve terminals by antagonizing the N-Methyl-D-Aspartate (NMDA) receptor, and DMF upregulates anti-oxidative pathways. OBJECTIVES Herein, using molecular hybridization strategy, we synthesized some new hybrid structures of Riluzole and DMF through some common successive synthetic pathways for evaluating their potential activity for remyelination in MS treatment. METHODS Molecular docking experiments assessed the binding affinity of proposed structures to the NMDA active site. The designed structures were synthesized and purified based on well-known chemical synthesis procedures. Afterward, in vivo evaluation for their activity was done in the C57Bl/6 Cuprizone-induced demyelination MS model. RESULTS AND CONCLUSION The proposed derivatives were recognized to be potent enough based on docking studies (ΔGbind of all derivatives were -7.2 to -7.52 compare to the Ifenprodil (-6.98) and Riluzole (-4.42)). The correct structures of desired derivatives were confirmed using spectroscopic methods. Based on in vivo studies, D4 and D6 derivatives exhibited the best pharmacological results, although only D6 showed a statistically significant difference compared to the control. Also, for D4 and D6 derivatives, myelin staining confirmed reduced degeneration in the corpus callosum. Consequently, D4 and D6 derivatives are promising candidates for developing new NMDA antagonists with therapeutic value against MS disorders.

LFA-1 regulated by IL-2/STAT5 pathway boosts antitumor function of intratumoral CD8 + T cells for improving anti-PD-1 antibody therapy. Oncoimmunology 2023; 13:2293511. [PMID: 38125721 PMCID: PMC10730141 DOI: 10.1080/2162402x.2023.2293511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Accepted: 12/07/2023] [Indexed: 12/23/2023] Open
Abstract
Anti-PD-1 antibody therapy has achieved success in tumor treatment; however, the duration of its clinical benefits are typically short. The functional state of intratumoral CD8+ T cells substantially affects the efficacy of anti-PD-1 antibody therapy. Understanding how intratumoral CD8+ T cells change will contribute to the improvement in anti-PD-1 antibody therapy. In this study, we found that tumor growth was not arrested after the late administration of anti-PD-1 antibody and that the antitumor function of CD8+ T cells decreased with tumor progression. The results of the RNA sequencing of CD8+ T cells infiltrating the tumor site on days 7 and 14 showed that the cell adhesion molecule Lymphocyte Function-associated Antigen-1 (LFA-1) participates in regulating the antitumor function of CD8+ T cells and that decreased LFA-1 expression in intratumoral CD8+ T cells is associated with tumor progression. By analyzing the Gene Expression Omnibus (GEO) database and our results, we found that the antitumor function of intratumoral CD8+ T cells with high LFA-1 expression was stronger. The formation of immune synapses is impaired in Itgal-si CD8+ T cells, resulting in decreased anti-tumor function. LFA-1 expression in intratumoral CD8+ T cells is regulated by the IL-2/STAT5 pathway. The combination of IL-2 and anti-PD-1 antibody effectively enhanced LFA-1 expression and the antitumor function of intratumoral CD8+ T cells. The adoptive transfer of OT-1 T cells overexpressing LFA-1, STAT5A, or STAT5B resulted in higher antitumor function, deferred tumor growth, and prolonged survival. These findings indicate that LFA-1-mediated immune synapse acts as a regulator of the antitumor function of intratumoral CD8+ T cells, which can be applied to improve anti-PD-1 antibody therapy.

P38γ modulates the lipid metabolism in non-alcoholic fatty liver disease by regulating the JAK-STAT signaling pathway. FASEB J 2023; 37:e22716. [PMID: 36527390 DOI: 10.1096/fj.202200939rr] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 11/08/2022] [Accepted: 12/05/2022] [Indexed: 12/23/2022]
Abstract
Non-alcoholic fatty liver disease (NAFLD) is a major health problem in Western countries and has become the most common cause of chronic liver disease. Although NAFLD is closely associated with obesity, inflammation, and insulin resistance, its pathogenesis remains unclear. The disease begins with excessive accumulation of triglycerides in the liver, which in turn leads to liver cell damage, steatosis, inflammation, and so on. P38γ is one of the four isoforms of P38 mitogen-activated protein kinases (P38 MAPKs) that contributes to inflammation in different diseases. In this research, we investigated the role of P38γ in NAFLD. In vivo, a NAFLD model was established by feeding C57BL/6J mice with a methionine- and choline-deficient (MCD) diet and adeno-associated virus (AAV9-shRNA-P38γ) was injected into C57BL/6J mice by tail vein for knockdown P38γ. The results indicated that the expression level of P38γ was upregulated in MCD-fed mice. Furthermore, the downregulation of P38γ significantly attenuated liver injury and lipid accumulation in mice. In vitro, mouse hepatocytes AML-12 were treated with free fatty acid (FFA). We found that P38γ was obviously increased in FFA-treated AML-12 cells, whereas knockdown of P38γ significantly suppressed lipid accumulation in FFA-treated AML-12 cells. Furthermore, P38γ regulated the Janus Kinase-Signal transducers and activators of transcription (JAK-STAT) signaling pathway. Inhibition of P38γ can inhibit the JAK-STAT signaling pathway, thereby inhibiting lipid accumulation in FFA-treated AML-12 cells. In conclusion, our results suggest that targeting P38γ contributes to the suppression of lipid accumulation in fatty liver disease.

Sis-25, a meroditerpenoid derivative with a cyclobutane scaffold, inhibits activated T cell proliferation by targeting GSK3β in vitro and in vivo. Eur J Pharmacol 2022; 929:175151.

Abstract
A series of novel scopariusicide derivatives were designed and synthesized starting from the main diterpenoid from the aerial parts of Isodon scoparius. Sis-25 was the most effective compound among them. The potential mechanism(s) of its immunosuppressive activity in vitro, as well as its effects on delayed type hypersensitivity (DTH) reaction and imiquimod-induced dermatitis in vivo were investigated in this study. Sis-25 inhibited anti-CD3/anti-CD28 mAbs, PHA or alloantigen-induced T cell proliferation without obvious cytotoxicity. Sis-25 was a highly selective inhibitor of GSK3-β and inhibited the mTOR/p70S6K pathway but not the PI3K/Akt, p38 MAPK/ERK 1/2 and JAK3/STAT5 pathways. Furthermore, Sis-25 significantly inhibited IFN-γ, IL-6 and IL-17 expression but not IL-10 expression in activated T cells. Finally, Sis-25 treatment mitigated the DNFB-induced DTH reaction and ameliorated imiquimod-induced dermatitis. In summary, Sis-25 exerted significant immunosuppressive activity by targeting GSK3β in vitro and in vivo. Sis-25 may guide the design of new drugs for more effective and safer treatments of autoimmune diseases and provide new insight into developing utilizations of Isodon scoparius.

Abstract
All-syn fused cyclobutanes remain an elusive chemotype and thus present an interesting synthetic challenge. Herein, we report the successful application of Pd-catalysed C(sp3)-H arylation of cyclobutane compounds to generate all-syn heterobicyclic fragments using an innovative 'inside-out' approach. Through this strategy we generate a virtual collection of 90 fragments, which we demonstrate to have enhanced three-dimensionality and superior fragment-like properties compared to existing collections.

Abstract
BACKGROUND AND PURPOSE Immunosuppressive drugs have shown great promise in treating autoimmune diseases in recent years. A series of novel oxazole derivatives were screened for their immunosuppressive activity. PO-322 [1H-indole-2,3-dione 3-(1,3-benzoxazol-2-ylhydrazone)] was identified as the most effective of these compounds. Here, we have investigated the mechanism(s) underlying the inhibition of T-cell proliferation in vitro by PO-322, as well as its effects on the delayed-type hypersensitivity (DTH) response and imiquimod-induced dermatitis in vivo. EXPERIMENTAL APPROACH T-cell proliferation and apoptosis were analysed with flow cytometry. Cell viability was assessed with a CCK-8 assay. Protein kinase activity was assessed by SelectScreen Kinase Profiling Services. The phosphorylation of signal-regulated molecules was measured by Western blot. Cytokine levels were determined by elisa. The effect of PO-322 on DTH and imiquimod-induced dermatitis was evaluated in BALB/c mice. KEY RESULTS PO-322 inhibited human T-cell proliferation with anti-CD3/anti-CD28 mAbs or alloantigen without significant cytotoxicity. Importantly, PO-322 was a selective inhibitor of the serum- and glucocorticoid-regulated kinase 1 (SGK1) and decreased NDRG1 phosphorylation but not p70S6K, STAT5, Akt, or ERK1/2 phosphorylation. Furthermore, PO-322 inhibited IFN-γ, IL-6, and IL-17 expression but not IL-10 expression. Finally, treatment with PO-322 was safe and effective for ameliorating the DTH response and imiquimod-induced dermatitis in mice. CONCLUSIONS AND IMPLICATIONS PO-322 exerted immunosuppressive activity in vitro and in vivo by selectively inhibiting SGK1 activity. PO-322 represents a potential lead compound for the design and development of new drugs for the treatment of autoimmune diseases.

Abstract
Seven new trialkyl-substituted benzene derivatives named benwamycins A-G (1-7), together with three known congeners, 8-10, were isolated from culture broth of the soil-derived Streptomyces sp. KIB-H1471. Their structures were elucidated by using 1D and 2D NMR analyses in combination with HRESIMS data. The absolute configurations of 1-9 were determined by chemical conversion and comparison of circular dichroism spectra and confirmed for 1 by single-crystal X-ray crystallography. Compounds 6 and 7 have a unique γ-pyrone-like ring on one side chain. Compounds 2 and 6 inhibited human T cell proliferation with IC50 values of 14.3 and 12.5 μM, respectively, without obvious cytotoxicity for naïve human T cells. Compounds 3 and 6 could weakly enhance insulin-stimulated glucose uptake.

Activation of Toll-Like Receptor 3 Induces Interleukin-1 Receptor Antagonist Expression by Activating the Interferon Regulatory Factor 3. J Innate Immun 2019; 12:304-320.

Abstract
Toll-like receptor 3 (TLR3) is a sensor of endogenous cell necrosis during the process of acute inflammation. Interleukin (IL)-1 receptor antagonist (IL-1Ra) is an anti-inflammatory cytokine and can negatively regulate the pathogenesis of inflammation. However, whether and how activation of TLR3 can regulate IL-1Ra expression has not been clarified. Here, we show that poly(I:C) induces IL-1Ra expression in primarily cultured human fibroblast-like synoviocytes and other types of cells. Induction of IL-1Ra by poly(I:C) was dependent on TLR3, but was independent of melanoma differentiation--associated protein 5 or retinoic acid-inducible gene I. Interferon regulatory factor 3 (IRF3) directly binds to the IL-1Ra promoter and promotes IL-1Ra expression in response to poly(I:C) stimulation. Induction of IL-1Ra by poly(I:C) was abolished by the inhibition of the NF-κB signaling, attenuated by the inhibition of the PI3K-Akt signaling, enhanced by inhibition of the ERK1/2 or MSK1/2 activation, but was independent of the p38 MAPK signaling. Treatment with poly(I:C) or Sendai virus elevated the levels of serum IL-1Ra in wild-type, but not in TLR3-/- or IRF3-/- mice. Our findings may provide new insights into the intrinsic anti-inflammatory function of TLR3 and double-stranded RNA-induced IL-Ra expression by TLR3 and its regulation.

Abstract
Immunosuppressants have shown striking achievements in treating autoimmune diseases in recent years. It is urgent to develop more immunosuppressants to provide more options for patients. PO-296 [2-(6-chlorobenzo[d]oxazol-2-yl)-4,5,6,7-tetrahydro-2H-indazol-3-ol] was identified as a novel benzoxazole derivative. We observed that it exhibits an obvious immunosuppressive activity to T lymphocytes. PO-296 significantly inhibited the proliferation of activated human T lymphocyte without cytotoxicity. Moreover, PO-296 did not affect the expression of cluster of differentiation (CD)-25 or CD69 but induced T lymphocyte cycle arrest in the G0/G1 phase. Furthermore, PO-296 inhibited interleukin (IL)-6, IL-17, and interferon gamma expression but had no effect on IL-2, IL-4, or IL-10. Yet, importantly, PO-296 inhibited the phosphorylation of signal transducer and activator of transcription 5 (STAT5), increased the phosphorylation of p70S6K, but did not affect the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mitogen-activated protein kinase pathway. In conclusion, these findings indicate that PO-296 inhibits human activated T-lymphocyte proliferation by affecting the janus kinase 3 (JAK3)/STAT5 pathway. PO-296 possesses a potential lead compound for the design and development of new immunosuppressants for the treatment of autoimmune diseases.

Improvement of glucocorticoid-impaired thymus function by dihydromyricetin via up-regulation of PPARγ-associated fatty acid metabolism. Pharmacol Res 2018; 137:76-88. [PMID: 30227260 DOI: 10.1016/j.phrs.2018.09.011] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 09/10/2018] [Accepted: 09/12/2018] [Indexed: 12/27/2022]
Abstract
T lymphocytes produced by the thymus are essential mediators of immunity. Accelerated thymic atrophy appears in the patients with administration of glucocorticoids (GCs) which are commonly-used drugs to treat autoimmune and infectious diseases, leading to dysregulation of immunity with manifestation of progressive diminution of new T cell production. However, there is no ideal method to overcome such side effects of GCs. In the current study, we proposed a composition of dexamethasone (DEX) and dihydromyricetin (DMY) derived from a medicinal plant, which could protect from DEX-induced thymus damage and simultaneously enhance the anti-inflammatory effect of DEX. In the current study, we found that DEX-damaged thymic cellularity and architecture, reduced thymocyte numbers, induced thymocyte apoptosis and dropped CD4+ and CD8+ double positive T cell numbers in thymus which was effectively improved by co-treatment with DMY. Quantification of signal joint TCR delta excision circles (TRECs) and Vβ TCR spectratyping analysis were employed to determine the thymus function with indicated treatments. The results showed that DEX-impaired thymus output and decreased TCR cell diversity which was ameliorated by co-treatment with DMY. iTRAQ 2D LC-MS/MS was applied to analyze the proteomic profiling of thymus of mice treated with or without indicated agents, followed by informatics analysis to identify the correlated signaling pathway. After validated by Western blotting and Real-time PCR, we found that PPARγ-associated fatty acid metabolism was increased in the thymic tissues of the animals treated with DMY plus DEX than the animals treated with DEX alone. The agonist and antagonist of PPARγ were further employed to verify the role of PPARγ in the present study. Furthermore, DMY demonstrated a synergistic effect with co-administration of DEX on suppressing inflammation in vivo. Collectively, DMY relieved thymus function damaged by DEX via regulation of PPARγ-associated fatty acid metabolism. Our findings may provide a new strategy on protection of thymus from damage caused by GCs by using appropriate adjuvant natural agents through up-regulation of PPARγ-associated fatty acid metabolism.

Abstract
BD750, a novel JAK3/STAT5 inhibitor, can inhibit T cell proliferation. This study aims to evaluate whether BD750 can induce tolerogenic dendritic cells (tolDC) and their function in experimental autoimmune encephalitis (EAE) in mice. Following BD750 treatment, LPS-induced maturation of DC, allogeneic T cell proliferation, Th1 and Th17 cell functional differentiation, the STAT5 and AKT activation were determined. The effect of tolDC loaded with antigen peptide on the development and severity of EAE and their splenic Th1 and Th17 cell responses were determined. In comparison with LPS-induced mature DC (mDC), BD750 treatment induced tolDC with lower expression levels of costimulatory molecules and pro-inflammatory cytokines and lower levels of STAT5 phosphorylation. TolDC inhibited allogeneic T cell proliferation and reduced Th1 and Th17 responses. Adoptive transfer of tolDC loaded with MOG35-55 inhibited the development and severity of EAE in mice, accompanied by reduced numbers of inflammatory infiltrates and decreased levels of demyelination in the spinal cord tissues of mice. In addition, treatment with tolDC loaded with antigen peptide also significantly reduced the frequency of splenic Th1 and Th17 cells in EAE mice. The effects of tolDC were similar to that of the JAK/STAT inhibitor, CP690550-treated DC. In conclusion, treatment with BD750 induced tolDC that inhibited pro-inflammatory T cell immunity in vitro and in vivo. BD750 and tolDC may be valuable for development of new therapies for EAE and other autoimmune diseases.

Abstract
Benzothiazole derivatives are known for various biological activities, and their potency in cancer therapy have received considerable attention in recent years. However, the poor water solubility of most benzothiazole derivatives has limited their clinical application. We developed BD926, a novel water-soluble benzothiazole derivative and showed here that it could inhibit the proliferation and induce apoptosis of human Ramos B-lymphoma cells. We further showed that BD926 triggered apoptosis through both mitochondria and endoplasmic reticulum pathways. Moreover, BD926 caused cell cycle arrest at G0/G1 stage. Furthermore, accumulation of reactive oxygen species (ROS) were observed after BD926 treatment and ROS inhibitor was able to attenuate BD926-induced apoptosis, which suggested that BD926-induced apoptosis may be due to over-producing ROS. These results demonstrate the anticancer effects of BD926 in cell models and raise the possibility for the application of BD926 in cancer therapy.

Abstract
Immunosuppressants are widely used for treatment of T cell-mediated autoimmune diseases and allogeneic graft rejection. However, because of the toxicity and tolerance of these drugs, novel immunosuppressants are urgently needed. We synthesized a series of novel water-soluble benzothiazole derivatives and found that BD926 [sodium 2-(benzo[d]thiazol-2-yl)-4,5,6,7-tetrahydro-2H-indazol-3-olate] had potent immunosuppressive activity. Treatment with BD926 significantly inhibited anti-CD3/anti-CD28 and alloantigen-induced human T cell proliferation as well as IL2-stimulated activated T cell proliferation in a dose-dependent manner in vitro. BD926 had no obvious cytotoxicity against human resting T cells, IL-4 treated activated T cells and fibroblast-like synoviocytes in our experimental conditions. Furthermore, BD926 induced cell cycle arrest at G0/G1 phase and inhibited the cyclin D3 and CDK 6 expression in activated T cells. BD926 inhibited the STAT5, but not Akt and p70S6K, phosphorylation in a dose-dependent manner in the IL-2-treated activated T cells. Interestingly, BD926 inhibited IFN-γ, IL-6 and IL-17, but not IL-2, IL-4 and IL-10, production in activated T cells. Finally, treatment with BD926 reduced delayed-type hypersensitivity in mice in a dose-dependent manner. Collectively, these data suggest that BD926 may be a lead compound for the design and development of new immunosuppressants for the intervention of allograft rejection and autoimmune diseases.

Abstract
BACKGROUND Contact hypersensitivity assay (CHS) faithfully models human allergies. The Stat5 transcription factors are essential for both lymphocyte development and acute immune responses. Although consequences of Stat5 ablation and transgenic overexpression for the lymphocyte development and functions have been extensively studied, the role of Stat5 gene dosage in contact allergies has not been addressed. OBJECTIVE We investigated the effect of Stat5 gene dosage modulation in contact allergies using CHS in mice. METHODS Transgenic animals heterozygous for the germline Stat5 null allele were subjected to CHS. To dissect cell type sensitive to Stat5 gene dosage, animals with Stat5 haplo-insufficiency in T cells, where one Stat5 allele was removed by Lck-Cre-mediated deletion (Stat5(ΔT/+)), were tested by CHS. Frequency of T cells, B cells, and monocytes were analyzed in Stat5(ΔT/+) and wild-type animals by flow cytometry. Proliferation of Stat5(ΔT/+) CD8(+) T cells was studied in vitro by stimulation with IL-4 and IL-2 cytokines, and changes in the expression of Stat5 target genes were assayed by quantitative real-time PCR assay. RESULT Haplo-insufficiency of Stat5 in T cells leads to the reduction in CD8(+) T cells in all lymphoid organs and attenuates CHS response. Stat5(ΔT/+) CD8(+) T cells failed to fully activate Stat5-dependent expression of cell cycle/survival target genes, such as Bcl2 and Pim1, and to proliferate efficiently in response to IL-2 and IL-4 cytokine. CONCLUSION Our data identify Stat5 as a dose-dependent regulator of CD8(+) T-cell functions in contact allergies and suggest that modulation of Stat5 dosage could be used to target contact allergies in humans.

Abstract
Thunder god vine, the dried roots of Tripterygium wilfordii, is a widely used traditional Chinese medicine. More than 200 bioactive complex natural products have been isolated from this herb. Inspired by the diversity of chemical structures and bioactivities of the components of this herb, the investigation to mine new chemical entities as potential drug leads led to the identification of 36 nitrogen-containing compounds. Among them, 18 new dihydro-β-agarofuran alkaloids (tripterygiumines A-L (1-12), M-Q (22-26), and R (33)) were identified from the spectroscopic data and chemical degradation studies. Tripterygiumine Q (26) exhibited immunosuppressive activity against human peripheral mononuclear cells with an IC50 value of 8.67 μM and showed no cytotoxicity, even at 100 μM, indicating that 26 may represent a novel scaffold for the development of new immunosuppressants.
