生物活性

Auriculasin is an anticancer agent that inhibits VEGFR2, PI3K/AKT/mTOR, MAPK. Auriculasin can inhibit cell proliferation, induce cell apoptosis, and inhibit angiogenesis, and promotes mitochondrial oxidative stress and ferroptosis. Auriculasin is also active at the cannabinoid receptor CB1 with an IC50 of 8.92 μM. Auriculasin can be used in cancer research, especially related diseases such as prostate cancer and non-small cell lung cancer, as well as research on the development of anti-angiogenic drugs[1][2][3][4][5].

Cell Migration Assay [1]

Cell Line: HUVECs
Concentration: 5 μM, 7.5 μM, 10 μM
Incubation Time: 12 h
Result: Inhibited VEGF-induced migration in wound-healing assay and invasion in trans-well assay.
体内研究
(In Vivo)

Auriculasin (5、10 μg/mL;皮下注射;单剂量) 在 C57BL/6 小鼠模型中,减少血红蛋白含量、内皮细胞积累和 VEGF 表达,抑制血管生成[1]
Auriculasin (5、10 mg/kg;口服灌胃;每 2 天一次;21 天) 在裸鼠 LNCaP 前列腺癌异种移植模型中,降低肿瘤大小、重量和体积,且无明显毒性[3]

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

Animal Model: 5-week-old male C57BL/6 mice, Matrigel plug model[1]
Dosage: 5 μg/mL, 10 μg/mL (in Matrigel with 20 units of heparin and 150 ng/mL VEGF)
Administration: Subcutaneous injection, single dose, 7 days
Result: Co-treated with Matrigel plugs and VEGF, showed marked reduction of red blood cells, lighter color, significantly reduced hemoglobin concentrations, dramatically blocked VEGF-induced vasculature formation, and reduced area of VEGF-staining cells compared to the VEGF alone group.

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.
