生物活性

Saikosaponin B1 is a bioactive constituent of Radix Bupleuri. Saikosaponin B1 is an agonist of the 5-HT2C receptor with an EC50 of 147.41 μM. Saikosaponin B1 inhibits the Hedgehog (Hh) signaling pathway by targeting the transmembrane protein SMO. Sailosaponin B1 can reduce liver fibrosis. Saikosaponin B1 has anti-cancer activities thus can be studies in research for cancers such as Medulloblastoma (MB)[1][4].

(In Vitro)

Saikosaponin B1 (10 nM-10 μM,36小时) 可降低转染的 Shh Light II 细胞中神经胶质瘤相关致癌基因同源物 (GLI)-荧光素酶活性水平,IC50 为 241.8 nM[1]
Saikosaponin B1 (5 μM,6-24小时) 不靶向 GLI 转录因子及其下游分子,因为 Saikosaponin B1 对转染的 LS174T 细胞中 PGE2 (HY-P3502B) 诱导的 TCF/LEF 和 GLI 活性,并且对 HEK293T 细胞中 TNF-α 诱导的 NF-κB 没有抑制活性[1]
Saikisaponin B1 (3 μM, 36 小时) 无法抑制通过 SUFU 敲除的 Shh Light II 细胞中限制 SUFU 负向调节而增加的 GLI-荧光素酶活性,这表明 Saikosaponin B1 通过 SUFU 的上游成分靶向 Hh 通路[1]
Saikisaponin B1 (3 μM, 36 小时) 显著抑制了 SAG (HY-12848) (一种与 SMO 结合的合成 Hh 通路激动剂) 在 Shh Light II 细胞中诱导的 Gli1 mRNA 表达增加,IC50 为 3.64 μM[1]
Saikisaponin B1 (10 nM-10 μM,72小时) 显著抑制了 DAOY 细胞系 (源自具有 GLI 转录活性的结节性MB) 的增殖[1]
Saikisaponin B1 (1-10 μM,0-24 小时) 可抑制 TGF-β1 诱导的 HSC 活化生物标志物[2]
Saikisaponin B1 (0-10 μM) 有生物标记时保留了活化 HSC-T6 细胞中纤维化蛋白表达的抑制活性,并表现出与 STAT3 最显著的结合[2]
Saikisaponin B1 (50 μM) 有生物标记时可下拉 STAT3 蛋白,但在 HSC-T6 细胞、LX-2 细胞和小鼠肝组织中与 JAK2IL-6 没有明显的相互作用[2]
Saikisaponin B1 (1-10 μM) 抑制 HSC-t6 和 LX-2 细胞中 Tyr 705 的 STAT3 磷酸化,但不影响 Ser 727 的磷酸化[2]
Saikisaponin B1 (5-10 μM,24 小时) 即使在IL-6 (20 ng/mL) 存在下, 10 μM的 Saikisaponin B1 也能破坏 HSC-T6细胞系中的 STAT3 二聚化[2]

RT-PCR [1]

Cell Line: Shh Light II cells transfected with luciferase reporter plasmids and Renilla-TK construct
Concentration: 10 nM-10 μM
Incubation Time: 36 h
Result: Significantly reduced the level of Gli1 and Ptch 1 mRNA (two transcriptional targets of GLI), which further confirmed the inhibition of Hh signaling.
Showed little cytotoxicity in response to effective concentrations in Shh Light II cells.

Western Blot Analysis [2]

Cell Line: Rat HSC-T6 cells; human LX-2 cells
Concentration: 10 nM-10 μM
Incubation Time: 0-24 h
Result: Inhibited the mRNA levels of the HSC activation biomarkers (α-SMA, collagen I, and vimentin) in TGF-β1-stimulated rat HSC-T6 cells.
Decreased expression of TGF-β1-induced α-SMA and Collagen I in human LX-2 cells and suggests that Saikisaponin B1 can reduce TGF-β1-induced HSC activation and matrix protein expression.

Saikosaponin B1 (10 mg/kg,皮下注射,每周两次,持续 4 周) 可减轻 CCl4 诱发的肝纤维化小鼠肝组织的纤维化组织病理学特征[2]
Saikosaponin B1 (20 mg/kg,腹腔注射,持续 4 周) 在 CCl4介导的肝纤维化 STAT3 敲除小鼠模型中未能进一步降低 CCl4 引起的肝纤维化,提示 STAT3 敲落消除了 Saikosaponin B1[2] 的抗纤维化作用。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
