Bruceantinol

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[1][2][3].
