Isotoosendanin

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].
