生物活性

Benzosceptrin C is an inhibitor for PD-L1, which promotes programmed cell death ligand (PD-L1) degradation in a lysosomal pathway, enhances the cytotoxicity of T-cells and exhibits antitumor activity[1].

体外研究
(In Vitro)

Benzosceptrin C (0-10 μM) 抑制 CRC 癌细胞中的 PD-L1 表达,通过破坏 PD-L1 检查点增强 T 细胞的细胞毒性,并抑制 CRC 癌细胞 RKO 和 HCT116 的增殖[1]
Benzosceptrin C (0-10 μM) 通过抑制 DHHC3 的活性阻断 PD-L1 的棕榈酰化,从而促进 PD-L1 的溶酶体降解,阻断 PD-L1PD-1 的直接相互作用,发挥免疫抗肿瘤作用[1]

Cell Proliferation Assay[1]

Cell Line: RKO and HCT116
Concentration: 0-10 μM
Incubation Time: 24 days
Result: Inhibited proliferation of tumor cells in dose-dependent manner.

Western Blot Analysis[1]

Cell Line: RKO and HCT116
Concentration: 0-10 μM
Incubation Time: 24 h
Result: Reduced levels of PD-L1 in time- and dose-dependent manner.
体内研究
(In Vivo)

Benzosceptrin C (5-50 mg/kg/day,腹腔注射,16 天) 通过激活肿瘤浸润 T 细胞和诱导细胞凋亡 (apoptosis) 抑制 MC38 异种移植 C57BL/6 小鼠的肿瘤生长[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: MC38 xenograft C57BL/6 mice[1]
Dosage: 5-50 mg/kg
Administration: i.p.,Once a day for 16 days
Result: Inhibited tumor growth with TGI of 30.4% and 43.1% at dose of 25 and 50 mg/kg with presence of T cells.

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.
