Silymarin is a natural polyphenolic flavonolignan mixture extracted from the seeds of Silybum marianum. It can inhibit tumor cell proliferation and angiogenesis, and improve insulin resistance, thus being widely used in liver disease-related research and adjuvant applications. Studies have shown that silymarin exhibits inhibitory activity against the SARS-CoV-2 main protease, and it has potential research value in the mechanism-related studies of COVID-19.

Product Introduction

Bioactivity

Description	Silymarin is a natural polyphenolic flavonolignan mixture extracted from the seeds of Silybum marianum. It can inhibit tumor cell proliferation and angiogenesis, and improve insulin resistance, thus being widely used in liver disease-related research and adjuvant applications. Studies have shown that silymarin exhibits inhibitory activity against the SARS-CoV-2 main protease, and it has potential research value in the mechanism-related studies of COVID-19.
In vitro	Mechanism of Silymarin involves different biochemical reactions, such as stimulation of the rate of ribosomal RNA synthesis by stimulating the transcription of polymerase I and ribosomal RNA genes, blockage of alpha-glycoside loops toxin intake, and protection of cell membranes from free radical-induced damage. Silymarin also displays a substantial protective effect against UVB-induced canceration at different stages, possibly through its strong antioxidant properties.
In vivo	The intravenous injection LD50 of Silymarin is 391.4 mg/kg, 70.1 mg/kg, 142.3 mg/kg for mice, rats, rabbits, respectively.

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% Saline /PBS/ddH₂O. So your working solution concentration is 2 mg/mL。

Stock solution preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(stock solution concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline /PBS/ddH₂O TargetMol | reagent

mix well and clarify
