THE EFFECTS OF REALSIL (SILYBIN-PHOSPHOLIPID-VITAMIN E COMPLEX) ON LIVER ENZYMES IN PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD) OR NON-ALCOHOLIC STEATO-HEPATITIS (NASH): A SYSTEMATIC REVIEW AND META-ANALYSIS OF RCTS

Lipid nanosystems for fatty liver therapy and targeted medication delivery: a comprehensive review

Fatty liver is considered to be the most common chronic liver disease with a high global incidence, which can lead to cirrhosis and liver cancer in severe cases, and there is no specific drug for the treatment of fatty liver in the clinic. The use of lipid nanosystems has the potential to be an effective means of fatty liver treatment. The pathogenesis and intervening factors associated with the development of fatty liver are reviewed, and the advantages and the disadvantages of different lipid nanosystems for the treatment of fatty liver are comprehensively discussed, including liposomes, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, microemulsions, and phospholipid complexes. The composition and characterisation of these lipid nanosystems are highlighted and summarised with a view to improving the efficiency of lipid nanosystems for the treatment of fatty liver. In addition, active targeting and passive targeting strategies used for fatty liver therapy are discussed in detail.

Silybin: A Review of Its Targeted and Novel Agents for Treating Liver Diseases Based on Pathogenesis

Liver disease represents a significant global public health concern. Silybin, derived from Silybum marianum, has been demonstrated to exhibit a range of beneficial properties, including anti-inflammatory, antioxidative, antifibrotic, antiviral, and cytoprotective effects. These attributes render it a promising candidate for the treatment of liver fibrosis, cirrhosis, liver cancer, viral hepatitis, non-alcoholic fatty liver disease, and other liver conditions. Nevertheless, its low solubility and low bioavailability have emerged as significant limitations in its clinical application. To address these limitations, researchers have developed a number of silybin formulations. This study presents a comprehensive review of the results of research on silybin for the treatment of liver diseases in recent decades, with a particular focus on novel formulations based on the pathogenesis of the disease. These include approaches targeting the liver via the CD44 receptor, folic acid, vitamin A, and others. Furthermore, the study presents the findings of studies that have employed nanotechnology to enhance the low bioavailability and low solubility of silybin. This includes the use of nanoparticles, liposomes, and nanosuspensions. This study reviews the application of silybin preparations in the treatment of global liver diseases. However, further high-quality and more complete experimental studies are still required to gain a more comprehensive understanding of the efficacy and safety of these preparations. Finally, the study considers the issues that arise during the research of silybin formulations.

Combined hepatoprotective pharmacotherapy for liver disease

Fixed-dose drug products as well as non-fixed hepatoprotective drug combinations are commonly used in modern clinical practice. Combined and concurrent drug use makes it possible to augment the pharmacological effects of individual agents, or extend the range of their potential indications. The drugs most commonly considered for combination therapy include essential phospholipids, glycyrrhizinic acid, ursodeoxycholic acid, silibinin, and S-adenosylmethionine. This paper discusses the rationale for combined use of liver-targeting drugs from a pathogenetic viewpoint, and provides a review of the evidence from clinical trials on combined pharmacotherapy for liver disease.

The Role of Thiazolidinediones in the Amelioration of Nonalcoholic Fatty Liver Disease: A Systematic Review

Non-alcoholic fatty liver disease (NAFLD) is a broad term encompassing hepatic steatosis and non-alcoholic steatohepatitis (NASH), a form of chronic hepatitis. This may, unfortunately, lead to terminal complications like cirrhosis and hepatocellular carcinoma (HCC). NAFLD is strongly associated with obesity, type 2 diabetes (T2DM), hypertension, and metabolic syndrome. The growing prevalence of NAFLD, its associated conditions, and its complications are alarming. The insulin sensitizer group "thiazolidinediones" has shown some therapeutic benefits in this condition. This systematic review is intended to focus on the clinical efficacy of this group in patients with NAFLD, employing PubMed, Google Scholar, and the Cochrane Library as databases. We discovered 10 randomized control trials (RCTs; nine involving pioglitazone and one involving rosiglitazone) involving 887 participants. All studies varied in duration from 6 to 24 months. Most of the involved trials had a small number of participants, and the intrinsic quality of the studies was mixed. Pioglitazone consistently improved histological parameters and normalized liver transaminases, although evidence supporting the benefits of other drugs in this class was minimal. Thiazolidinediones, particularly pioglitazone, have proven efficacious in patients with NAFLD/NASH. However, more extensive trials need to be carried out to investigate this drug class's benefits further. Unfortunately, this drug has attendant side effects like weight gain and fractures, limiting its widespread use; hence, careful selection for likely candidates is imperative.

The NLRP3 Inflammasome in Non-Alcoholic Fatty Liver Disease and Steatohepatitis: Therapeutic Targets and Treatment

Non-alcoholic fatty liver disease (NAFLD) is among the most prevalent primary liver diseases worldwide and can develop into various conditions, ranging from simple steatosis, through non-alcoholic steatohepatitis (NASH), to fibrosis, and eventually cirrhosis and hepatocellular carcinoma. Nevertheless, there is no effective treatment for NAFLD due to the complicated etiology. Recently, activation of the NLPR3 inflammasome has been demonstrated to be a contributing factor in the development of NAFLD, particularly as a modulator of progression from initial hepatic steatosis to NASH. NLRP3 inflammasome, as a caspase-1 activation platform, is critical for processing key pro-inflammatory cytokines and pyroptosis. Various stimuli involved in NAFLD can activate the NLRP3 inflammasome, depending on the diverse cellular stresses that they cause. NLRP3 inflammasome-related inhibitors and agents for NAFLD treatment have been tested and demonstrated positive effects in experimental models. Meanwhile, some drugs have been applied in clinical studies, supporting this therapeutic approach. In this review, we discuss the activation, biological functions, and treatment targeting the NLRP3 inflammasome in the context of NAFLD progression. Specifically, we focus on the different types of therapeutic agents that can inhibit the NLRP3 inflammasome and summarize their pharmacological effectiveness for NAFLD treatment.

Inhibition of TMEM16A by Natural Product Silibinin: Potential Lead Compounds for Treatment of Lung Adenocarcinoma

Background: Effective anticancer therapy can be achieved by identifying novel tumor-specific drug targets and screening of new drugs. Recently, TMEM16A has been identified to be overexpressed in lung adenocarcinoma, and inhibitors of TMEM16A showed obvious antitumor efficacy.

Methods: YFP fluorescence quenching and whole-cell patch clamp experiments were used to explore the inhibitory effect of silibinin on TMEM16A. Molecular docking and site-directed mutagenesis were performed to confirm the binding sites of silibinin and TMEM16A. MTT assay, wound healing assay, and annexin-V assay were used to detect the effect of silibinin on cancer cell proliferation, migration, and apoptosis. shRNA was transfected into LA795 cells to knock down the expression of endogenous TMEM16A. Tumor xenograft mice combined with Western blot experiments reveal the inhibitory effect and mechanism of silibinin in vivo.

Results: Silibinin concentration dependently inhibited the whole-cell current of TMEM16A with an IC₅₀ of 30.90 ± 2.10 μM. The putative binding sites of silibinin in TMEM16A were K384, R515, and R535. The proliferation and migration of LA795 cells were downregulated by silibinin, and the inhibition effect can be abolished by knockdown of the endogenous TMEM16A. Further, silibinin was injected to tumor xenograft mice which exhibited significant antitumor activity without weight loss. Finally, Western blotting results showed the mechanism of silibinin inhibiting lung adenocarcinoma was through apoptosis and downregulation of cyclin D1.

Conclusion: Silibinin is a novel TMEM16A inhibitor, and it can be used as a lead compound for the development of lung adenocarcinoma therapy drugs.
