silibinin

Silibinin (Silybin) 是水飞蓟的主要活性成分，具有抗癌和化疗预防作用，能抑制细胞增殖和迁移。

Silibinin-d3 是 Silibinin 的氘代化合物。Silibinin 的 CAS 号为 22888-70-6。Silibinin 是水飞蓟的主要活性成分，具有抗癌和化疗预防作用，能抑制细胞增殖和迁移。

Silybin 是一种来自于Silybum 的黄酮类化合物，可抑制P-糖蛋白辅助的细胞外流，可抑制细胞色素P450酶，具有耐受性良好的优点，可用于肝中毒和慢性肝炎及肝硬化的辅助治疗，在化妆品应用上具有抗氧化和抗炎活性，还能够阻断MCT8转运蛋白。

Silybin B (Silibinin B) 是雷洛昔芬4′-和6-葡萄糖醛酸化的有效抑制剂，是水飞蓟素有效的抗纤维原性和抗低聚物成分，具有清除1,1-二苯基-2-吡啶酰肼(DPPH)自由基的活性 ，可通过减轻 DNA 损伤和细胞凋亡对顺铂诱导的神经毒性具有保护作用。Silybin B 对人慢性髓系白血病 K562细胞的生长抑制和诱导凋亡有较强的作用。

(±)-Silybin为Silybin的消旋体，具备诱导细胞凋亡(apoptosis)、保肝、抗氧化、抗炎及抗癌等多重生物活性。

Tpl2 kinase inhibitor is an inhibitor of tumor progression locus 2 (Tpl2; IC50= 0.05 μM).1It is selective for Tpl2 over MEK, p38 MAPK, Src, MK2, and PKC (IC50s = >40, 180, >400, 110, and >400 μM, respectively). Tpl2 kinase inhibitor inhibits LPS-induced TNF-α production in isolated human monocytes and whole blood (IC50s = 0.7 and 8.5 μM, respectively). It enhances differentiation induced by calcitriol in HL-60 and U937 leukemia cells when used at a concentration of 5 μM.2Tpl2 kinase inhibitor (5 μM) inhibits the proliferation of KG-1a leukemia cells.3 1.Garvin, L.K., Green, N., Hu, Y., et al.Inhibition of Tpl2 kinase and TNF-α production with 1,7-naphthyridine-3-carbonitriles: Synthesis and structure-activity relationshipsBioor.
