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.

| 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. |
