COA 产品使用指南 技术支持

Isotoosendanin 是一种具有口服活性的 TGFβR1 抑制剂,可抑制其激酶活性 (IC50 = 6732 nM)。Isotoosendanin 通过直接靶向 SHP-2,增强其稳定性并减少其泛素化,从而抑制 JAK/STAT3 信号通路。Isotoosendanin 抑制 TGF-β 诱导的三阴性乳腺癌 (TNBC) 细胞的迁移、侵袭和转移。Isotoosendanin 在 TNBC 异种移植模型和 A549 异种移植肿瘤中显示出抗肿瘤活性。Isotoosendanin 在醋酸诱导的血管通透性和 λ-角叉菜胶诱导的后爪水肿试验中表现出显著的抗炎效果。Isotoosendanin 可用于非小细胞肺癌 (NSCLC)、三阴性乳腺癌 (TNBC) 和炎症研究。

生物活性

Isotoosendanin is an orally active TGFβR1 inhibitor and abrogating its kinase activity (IC50 = 6732 nM). Isotoosendanin inhibits the JAK/STAT3 signaling pathway by directly targeting SHP-2, enhancing its stability, and reducing its ubiquitination. Isotoosendanin inhibits TGF-β-induced reduces the migration, invasion, and metastasis in triple-negative breast cancer (TNBC) cells. Isotoosendanin exhibits anti-tumor efficacy in TNBC xenograft models and A549 xenograft tumors. Isotoosendanin exhibits significant anti-inflammatory effects in acetic acid-induced vascular permeability and λ-carrageenan-induced hind paw edema tests. Isotoosendanin can be used for the study of non-small cell lung cancer (NSCLC), TNBC and inflammation[1][2][3].

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.
