Depression is one of the most frequent psychiatric disorders of Alzheimer's disease (AD). Depression and anxiety are associated with increased risk of developing AD. Silibinin, a flavonoid derived from milk thistle (Silybum marianum), has been used as a hepato-protectant in the clinical treatment of liver diseases. In this study, the effect of silibinin on Aβ-induced anxiety/depression-like behaviors in rats was investigated. Silibinin significantly attenuated anxiety/depression-like behaviors caused by Aβ1-42-treatment as shown in tail suspension test (TST), elevated plus maze (EPM) and forced swimming tests (FST)...

Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases...

Breast cancer is the most vicious killer for women, and tumor metastasis is one of the leading causes of breast cancer therapy failure. In this study, a new pH-sensitive polymer (polyethylene glycol-block-poly[(1,4-butanediol)-diacrylate-β-N,N-diisopropylethylenediamine], BDP) was synthesized. Based on BDP, docetaxel/silibinin co-delivery micelles (DSMs) was constructed. DSM had a well-defined spherical shape under the transmission electron microscope with average hydrodynamic diameter of 85.3±0.4 nm, and were stable in the bloodstream but could dissociate to release the chemotherapeutic agents in the low pH environment of the endo/lysosomes in the tumor cells...

Silibinin is a plant derived flavonolignan known for its multiple biological properties, but its role in the promotion of bone formation has not yet been well studied. Moreover, the delivery of Silibinin is hindered by its complex hydrophobic nature, which limits its bioavailability. Hence, in this study, we fabricated a drug delivery system using chitosan nanoparticles loaded with Silibinin at different concentrations (20μM, 50μM, and 100μM). They were then incorporated into scaffolds containing Alginate and Gelatin (Alg/Gel) for the sustained and prolonged release of Silibinin...

Signal transducer and activator of transcription 3 (STAT3) has a prominent role in mediating resistance to conventional chemo-/radio-therapies and modern targeted drugs. While a number of STAT3 inhibitors have been shown to enhance the efficacy of therapeutic agents in vitro, the majority of them have yet to enter clinical evaluation mostly because of lack of efficacy issues. Silibinin is the main component of the silymarin complex, a standardized extract obtained from the seeds of the milk thistle herb Silybum marianum...

Silibinin is a flavonolignan extracted from seeds of milk thistles. Traditionally, it has been used as a therapeutic agent for liver disorders, and now it is well-known for its anti-cancer effects. However, studies on anti-cancer effects of silibinin on choriocarcinoma are very limited. Therefore, we performed proliferation and apoptosis assays to determine effects of silibinin on the viability of human choriocarcinoma (JAR and JEG3) cells. Our results showed that silibinin significantly inhibited proliferation and induced apoptosis in both JAR and JEG3 cells, and significantly increased reactive oxygen species (ROS) and lipid peroxidation...

Human invasive pulmonary aspergillosis (IPA) is a serious infectious disease mainly caused by Aspergillus fumigatus (A. fumigatus). Pulmonary microvascular endothelial cells (PMVECs) are important ones in the human lung tissue. However, it remains unclear about the role of PMVECs in IPA. In the present study, we cocultured PMVECs with A. fumigatus. We observed that A. fumigatus induced dose- and time-dependent increases of interleukin 6 (IL-6), interleukin 1β (IL-1β) and intercellular adhesion molecule 1 (ICAM-1) concentration in the cultures...

HepaRG cells are widely used as an in vitro model to assess drug-induced hepatotoxicity. However, only few studies exist so far regarding their suitability to detect the effects of drugs requiring a preceding activation via the cytochrome P450 (CYP) system. A prototypic substance is the anti-tuberculosis agent INH, which is metabolized into N-acetylhydrazine, which then triggers hepatotoxicity. Therefore, the aim of the present study was to test if this effect can also be detected in HepaRG cells and if it can be counteracted by the known hepatoprotectant silibinin...

Silibinin is a natural flavonoid with a strong antioxidant property and weak cytotoxic activity. It has demonstrated anti-tumoural activity against many types of malignancies; however, due to its hydrophobic structure, it has poor water solubility, bioavailability and permeability across intestinal epithelial cells. To improve the effect of silibinin, we have vehiculated silibinin by a highly stable niosomal nanostructure based on a Span 60/cholesterol (CH)/N-trimethyl chitosan (TMC) system in order to study its potential application for the delivery of silibinin in T47D cultured under three-dimensional (3D) and two-dimensional (2D) conditions...
