BACKGROUND: Metabolic syndrome is the cluster of risk factors that leads to increased episodes of cardiovascular disease (CVD). These risk factors include but are not limited to obesity, non-alcoholic fatty liver (NAFLD), dyslipidemia, and type 2 diabetes. Since the pathogenesis of metabolic syndrome has multiple metabolic origins, there is no single treatment for it. Pharmacological approaches consist of separate drugs which target at individual risk factors which pose various side effects...

Silibin, a flavonoid from the seeds of Silybum marianum (L.) Gaertn. (Asteraceae) has been reported to produce curative properties in diabetes. Autophagy is generated by a vast array of insults for removal of damaged proteins and organelles from the cell. Inadequate autophagy promotes endothelial cells dysfunction and delays in diabetic ulcers recovery. We hypothesized that silibinin could protect endothelial cells against high glucose-induced damage by engaging autophagic responses. HUVECs viability was evaluated by MTT assay...

REVIEW
Michal Bijak
Milk thistle (Silybum marianum) is a medicinal plant that has been used for thousands of years as a remedy for a variety of ailments. The main component of S. marianum fruit extract (silymarin) is a flavonolignan called silybin, which is not only the major silymarin element but is also the most active ingredient of this extract, which has been confirmed in various studies. This compound belongs to the flavonoid group known as flavonolignans. Silybin's structure consists in two main units. The first is based on a taxifolin, the second a phenyllpropanoid unit, which in this case is conyferil alcohol...
