PURPOSE We recently demonstrated the strong anticancer efficacy of silibinin,an active constituent of a widely consumed dietary supplement milk thistle extract, against human prostate cancer cells in culture and nude mice xenografts. We also observed that pharmacologically achievable concentrations of silibinin in animal studies were in the range of 25-100 microM, depending on the dose regimen,...

Chemical warfare agent sulfur mustard (HD) inflicts delayed blistering and incapacitating skin injuries. To identify effective countermeasures against HD-induced skin injuries, efficacy studies were carried out employing HD analog 2-chloroethyl ethyl sulfide (CEES)-induced injury biomarkers in skin cells and SKH-1 hairless mouse skin. The data demonstrate strong therapeutic efficacy of silibini...

PURPOSE Curcumin is a hydrophobic polyphenol isolated from dried rhizome of turmeric. Clinical usefulness of curcumin in the treatment of cancer is limited due to poor aqueous solubility, hydrolytic degradation, metabolism, and poor oral bioavailability. To overcome these limitations, we proposed to fabricate curcumin-piperine, curcumin-quercetin and curcumin-silibinin loaded polymeric nanoform...

We have reported recently the anticancer effect of flavonoid antioxidant silymarin, the major part of milk thistle extract, against advanced human prostate carcinoma DU145 cells (X. Zi et al., Cancer Res., 58: 1920-1929, 1998) and later identified that silibinin is the main active component in silymarin responsible for its effect in cell culture studies. On the basis of these observations, here...

Silibinin is a natural flavonoid with anti-diabetic activity. Glucagon-like peptide−1 (GLP−1), an intestinal hormone mainly secreted from L cells, which regulates insulin production and sensitivity, appears to be potential therapeutic strategy for T2DM. The current study aims determine the protective effect of silibinin against palmitic acid (PA)-induced damage in GLUTag cells. results revealed...

Background and objective: According to reports, a serine protease inhibitor (Maspin) suppresses metastasis, invasion and angiogenesis in breast and prostate cancers. Silibinin is a natural polyphenolic flavonoid with anti-cancer activity. We assessed the effects of silibinin on cell viability, maspin and ERα gene expression in MCF-7 cell line. <s...

Bone integrity abnormality and imbalance between bone formation by osteoblasts and bone resorption by osteoclasts are known to result in metabolic bone diseases such as osteoporosis. Silymarin-rich milk thistle extract (MTE) and its component silibinin enhanced alkaline phosphatase activity of osteoblasts but reduced tartrate-resistant acid phosphatase (TRAP) activity of osteoclasts. The osteop...

Herbal-derived medicines have introduced as sources of novel drugs due to minimum systemic side effects. Silibinin as a flavonoid compound has showed with effective chemotherapeutic effects on different cancers. Here, we investigated the impact of combination therapy of silibinin, with paclitaxel and cisplatin in inhibition of proliferation and induction of apoptosis in MCF-7 cells. Cell prolif...

OBJECTIVES Our study sought to evaluate the effects of silibinin in patients with active rheumatoid arthritis (RA) treated with methotrexate (MTX). METHODS We conducted a randomized multi-center, double-blind, placebo-controlled clinical trial over a 16-week treatment period at the Al-Sader and Baghdad Teaching Hospitals in Najaf and Baghdad, respectively. A total of 60 patients (30 of each s...

Solar radiation is the causal etiologic factor in the development of nonmelanoma skin cancer (NMSC). Depletion of the stratospheric ozone layer leads to an increase in ambient UV radiation loads, which are expected to further raise skin cancer incidence in many temperate parts of the world, including the United States, suggesting that skin cancer chemopreventive approaches via biomarker efficac...
