Reduction of osteoclast formation and survival following suppression of cytokines by diacerein in periodontitis. Biomed Pharmacother 2024; 177:117086. [PMID: 39013222 DOI: 10.1016/j.biopha.2024.117086] [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: 04/23/2024] [Revised: 06/29/2024] [Accepted: 07/01/2024] [Indexed: 07/18/2024] Open
Abstract
Periodontitis causes an increase in several bioactive agents such as interleukins (IL), tumor necrosis factor (TNF)-α and receptor activator of NF-kB ligand (RANKL), which induce the osteoclast formation and activity. Since diacerein exerts anti-TNF-α and anti-IL-1 effects, alleviating bone destruction in osteoarthritis, we investigated whether this drug inhibits the formation and survival of osteoclast in the periodontitis. Rats were distributed into 3 groups: 1) group with periodontitis treated with 100 mg/kg diacerein (PDG), 2) group with periodontitis treated with saline (PSG) and group control (CG) without any treatment. After 7, 15 and 30 days, the maxillae were collected for light and transmission electron microscopy analyses. Gingiva samples were collected to evaluate the mRNA levels for Tnf, Il1b, Tnfsf11 and Tnfrsf11b by RT-qPCR. In PDG, the expression of Tnf and Il1b genes reduced significantly compared to PSG, except for Tnf expression at 7 days. The number of osteoclasts reduced significantly in the PDG in comparison with PSG at 7 and 15 days. In all periods, the IL-6 immunoexpression, RANKL/OPG immunoexpression and mRNA levels of Tnfsf11/Tnfrsf11b ratio were significantly lower in PDG than in PSG. PDG exhibited significantly higher frequency of TUNEL-positive osteoclasts than in PSG and CG at all time points. Osteoclasts with caspase-3-immunolabelled cytoplasm and nuclei with masses of condensed chromatin were observed in PDG, confirming osteoclast apoptosis. Diacerein inhibits osteoclastogenesis by decreasing Tnf and Il1b mRNA levels, resulting in decreased RANKL/OPG ratio, and induces apoptosis in osteoclasts of alveolar process of rat molars with periodontitis.

Abstract
OBJECTIVES Increasing literature data have suggested that the genus Polygonum L. possesses pharmacologically important plant secondary metabolites. These bioactive compounds are implicated as effective agents in preclinical and clinical practice due to their pharmacological effects such as anti-inflammatory, anticancer, antidiabetic, antiaging, neuroprotective or immunomodulatory properties among many others. However, elaborate pharmacological and clinical data concerning the bioavailability, tissue distribution pattern, dosage and pharmacokinetic profiles of these compounds are still scanty. KEY FINDINGS The major bioactive compounds implicated in the therapeutic effects of Polygonum genus include phenolic and flavonoid compounds, anthraquinones and stilbenes, such as quercetin, resveratrol, polydatin and others, and could serve as potential drug leads or as adjuvant agents. Data from in-silico network pharmacology and computational molecular docking studies are also highly helpful in identifying the possible drug target of pathogens or host cell machinery. SUMMARY We provide an up-to-date overview of the data from pharmacodynamic, pharmacokinetic profiles and preclinical (in-vitro and in-vivo) investigations and the available clinical data on some of the therapeutically important compounds of genus Polygonum L. and their medical interventions, including combating the outbreak of the COVID-19 pandemic.

Abstract
This study was designed to investigate the effects of rhein, the active metabolite of diacerhein, on the metabolic functions of human chondrocytes cultured in alginate beads. Enzymatically isolated osteoarthritic (OA) chondrocytes were cultured in alginate beads in a well-defined culture medium for 12 days. Rhein was tested in a range of concentrations comprised between 10(-7) and 4 x 10(-5)M, in the presence or absence of 10(-10)M IL-1beta. Interleukin (IL)-6 and -8, macrophage inflammatory protein (MIP-1beta), stromelysin-1 (MMP-3), aggrecan (AGG), tissue inhibitor of metalloproteinases-1 (TIMP-1), prostaglandin E(2) (PGE(2)) and nitric oxide (NO) productions were assayed. Cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) mRNA steady-state levels were also quantified. In the basal condition, 10(-5)M rhein increased by 46.5% the production of AGG, decreased by 17-30% the production of IL-6, MMP-3, NO and MIP-1beta but enhanced by 50% the production of PGE(2). IL-1beta increased IL-6, IL-8, MIP-1beta, NO, PGE(2) and MMP-3 productions, but inhibited AGG and TIMP-1 synthesis. Rhein partially reversed the effect of IL-1beta on TIMP-1 and NO production, had no effect on AGG, IL-6 and MIP-1beta production, but up-regulated the IL-1beta stimulated PGE(2) production. The COX-2 and iNOS mRNA levels and IL-8 production were not modified by rhein.Overall, these results contribute to explain the clinical efficiency of rhein and give new information on its mechanisms of action.

Abstract
OBJECTIVE IL-1beta plays a fundamental role in osteoarthritis (OA) pathophysiology and cartilage destruction. Targeting the activation mechanism of this cytokine appears to be important as a therapeutic approach. As the interleukin-1 converting enzyme (ICE) is the physiologic modulator of the production of active IL-1beta, we investigated the effect of diacerhein and its active metabolite rhein used in the treatment of OA patients, on the enzyme expression and synthesis on human OA cartilage. Further, we looked at the effect of both drugs on the production of the active form of IL-1beta and IL-18. METHODS The expression and synthesis of ICE were investigated on human OA cartilage explants using in-situ hybridization and immunohistochemical methods, respectively. The effect of the drugs on ICE OA chondrocytes was also determined by Northern blotting and a specific ELISA assay. Furthermore, the effect of both drugs on the level of active IL-1beta and IL-18 was examined by immunohistochemistry. RESULTS Data showed that diacerhein and rhein have no true effect on reducing total ICE mRNA by both Northern blotting analysis and in-situ hybridization. A marked and statistically significant decrease was, however, found for protein production. ELISA showed a reduction of 31% (P< 0.04) for diacerhein and 50% (P< 0.02) for rhein. The drugs' immunohistological cell score reduction was similar to data from the ELISA, and a statistical significant reduction of ICE production was found at both superficial and deep zones of the cartilage. IL-1beta and IL-18 were both preferentially produced in chondrocytes of the superficial zone. For each of these cytokines, both drugs demonstrated a statistically significant decrease in this zone. A marked decrease was also noted in the deep zone, but statistical significance was reached only for rhein. CONCLUSION These results provide a novel regulatory mechanism by which diacerhein and rhein could exert a down-regulation on IL-1's effect on OA cartilage.

Abstract
Diacerein is a drug for the treatment of patients with osteoarthritis. This drug is administered orally as 50 mg twice daily. Diacerein is entirely converted into rhein before reaching the systemic circulation. Rhein itself is either eliminated by the renal route (20%) or conjugated in the liver to rhein glucuronide (60%) and rhein sulfate (20%); these metabolites are mainly eliminated by the kidney. The pharmacokinetics characteristics of diacerein are about the same in young healthy volunteers and elderly people with normal renal function, both after a single dose (50 mg) or repeated doses (25 to 75 mg twice daily). Rhein kinetics after single oral doses of diacerein are linear in the range 50 to 200 mg. However, rhein kinetics are time-dependent, since the nonrenal clearance decreases with repeated doses. This results in a moderate increase in maximum plasma concentration, area under the plasma concentration-time curve and elimination half-life. Nevertheless, the steady-state is reached by the third administration and the mean elimination half-life is then around 7 to 8 hours. Taking diacerein with a standard meal delays systemic absorption, but is associated with a 25% increase in the amount absorbed. Mild-to-severe (Child Pugh's grade B to C) liver cirrhosis does not change the kinetics of diacerein, whereas mild-to-severe renal insufficiency (creatinine clearance < 2.4 L/h) is followed by accumulation of rhein which justifies a 50% reduction of the standard daily dosage. Rhein is highly bound to plasma proteins (about 99%), but this binding is not saturable so that no drug interactions are likely to occur, in contrast to those widely reported with nonsteroidal anti-inflammatory drugs. Except for moderate and transient digestive disturbances (soft stools, diarrhoea), diacerein is well tolerated and seems neither responsible for gastrointestinal bleeding nor for renal, liver or haematological toxicity.
