Bruceantinol
Based on 1 Customer Validation
Bruceantinol is a quassinoid that can be isolated from Brucea javanica, inhibits pepper mottle virus (PepMoV) in pepper. Bruceantinol is a STAT3 inhibitor demonstrating potent antitumor activity in in vitro and in vivo human colorectal cancer (CRC) models. Bruceantinol has potent anti-leukemic activity. Bruceantinol strongly inhibits STAT3 DNA-binding ability (IC50 = 2.4 pM), blocks the constitutive and IL-6-induced STAT3 activation, and suppresses transcription of MCL-1, PTTG1, survivin and c-Myc. Bruceantinol binds with CDK2/4/6 to facilitate protein degradation through proteasome pathway. Bruceantinol can dose- and time-dependently reduces the cell growth, impede cell proliferation, disrupts the cell cycle, and induces necrosis in MCF-7 cells and apoptosis in MDA-MB-231 cells.

Bruceantinol (Compound 4) (5-40 μM) shows strong inactivation effect against PepMoV with a minimum inhibitory concentration of 10 μM in C. annuum[1].
Bruceantinol (Compound BOL) (0-100 nM, 24 h) significantly decreases colony formation in a dose-dependent manner across the human CRC cell line panel (HCT116, HCT116 p53-/-, HCA-7, H630 and H630R1)[2].
Bruceantinol (300 nM, 24 h) alters the expression of 25 proteins (p-STAT3, MCL-1, c-Myc, and cleaved caspase-7) in HCT116 cells, in which the STAT3-mediated signal pathway is significantly suppressed[2].
Bruceantinol (30 nM, 0-24 h) inhibits STAT3 phosphorylation in HCT116 cells[2].
Bruceantinol (10-300 nM, 24 h) potently suppresses IL-6-induced activation of STAT3 in CRC cells[2].
Bruceantinol (0-1000 nM, 24 h) significantly decreases expression of MCL-1, c-Myc, and surviving in a dose-dependent manner[2].
Bruceantinol (0-1600 nM, 24-48 h) reduces breast cancer cell (MCF-7 and MDA-MB-231) growth[3].
Bruceantinol (100-400 nM, 24 h) results in a gradual decrease in the number of cells in G0/G1 with a corresponding increase in the cell numbers in S and G2/M in MCF-7 and MDA-MB-231 cells[3].
Bruceantinol (100-400 nM, 10 h) decreases CDK2/4/6 protein levels dependently on the proteasome pathway in MCF-7 and MDA-MB-231 cells[3].
