生物活性

产品描述	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.
体外活性	Silymarin的作用机制涉及不同的生化反应，如通过刺激聚合酶I和核糖体RNA基因的转录来增加核糖体RNA合成的速率、阻止α-糖苷环毒素的摄取，以及保护细胞膜免受自由基诱导的损伤。Silymarin还在不同阶段对UVB诱导的癌变展现出显著的保护效果，这可能通过其强大的抗氧化性质实现。
体内活性	Silymarin 的静脉注射LD50分别对于小鼠、大鼠、兔子为391.4 mg/kg、70.1 mg/kg、142.3 mg/kg。
别名	水飞蓟素
