The gram-scale isolation of the major flavonolignan diastereoisomers from milk thistle ( Silybum marianum) extract provided an entree into the isolation of two related analogues that are present in extremely minute quantities. The isolation and structure elucidation of these two new compounds, which we have termed isosilybin C and isosilybin D due to their structural similarities to isosilybin A and isosilybin B, respectively, afforded a preliminary analysis of structure-activity relationships toward prostate cancer growth, survival, and apoptotic endpoints.

Objective: This study aims to evaluate the effect of silymarin on insulin resistance and insulin sensitivity through a systematic review and meta-analysis of randomized controlled trials (RCTs).

Methods: We searched PubMed, Embase, Web of Science, and Cochrane Library up to September 2024 for relevant RCTs. The intervention required silymarin supplementation for at least 4 weeks.

Background/objectives: extract, obtained via microwave-enhanced extraction, was evaluated for its antioxidant, antidiabetic, and antimicrobial activities to explore its therapeutic potential.

Methods: The extraction was performed using microwave-enhanced techniques, and LC-MS/MS was employed to profile the metabolites in the extract. Total phenolic and flavonoid contents were quantified using spectrophotometric methods.

Metabolic Dysfunction-Associated Steatotic Liver Disease and the Cardiovascular System.

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed nonalcoholic fatty-liver disease, is an important and rising health issue with a link with atherosclerotic cardiovascular (CV) disease (CVD), affecting ∼25-30% of the adults in the general population; in patients with diabetes, its prevalence culminates to ∼70%; its evolutive form, nonalcoholic steatohepatitis, is estimated to be the main cause of liver transplantation in the future. MASLD is a multisystem disease that affects, besides the liver, extra-hepatic organs and regulatory pathways; it raises the risk of type 2 diabetes mellitus (T2D), CVD, and chronic kidney disease; the disease may also progress to hepatocellular carcinoma. Its diagnosis requires hepatic steatosis and at least one cardiometabolic risk factor and the exclusion of both significant alcohol consumption and other competing causes of chronic liver disease.

Introduction: is a medicinal plant that produces silymarin, which has been demonstrated to possess antiviral, anti-neurodegenerative, and anticancer activities. Silybin (A+B) are two major hepatoprotective flavonolignans produced predominantly in fruits. Several attempts have been made to increase the synthesis of silymarin, or its primary components, silybin (A+B).

Cancer, one of the deadliest diseases, has remained the epicenter of biological research for more than seven decades. Yet all the efforts for a perfect therapeutic cure come with certain limitations. The use of medicinal plants and their phytochemicals as therapeutics has received much attention in recent years.
