(E)-3,4-Dimethoxycinnamic acid is the less active isomer of 3,4-Dimethoxycinnamic acid. 3,4-Dimethoxycinnamic acid is a monomer extracted and purified from Securidaca inappendiculata Hassk. 3,4-Dimethoxycinnamic acid exerts anti-apoptotic effects on L-02 cells via the ROS-mediated signaling pathway[1]. Anti-apoptotic effects[1].
3,4-Dimethoxycinnamic acid (Methyl ferulic acid; 25, 50 and 100 µM) attenuates the ethanol-induced apoptosis of ethanolexposed L-02 cells[1]. 3,4-Dimethoxycinnamic acid (25, 50 and 100 µM) inhibits the expression levels of Nox4 and p22phox in L-02 cells[1]. 3,4-Dimethoxycinnamic acid (25, 50 and 100 µM) treatment attenuates ethanol-induced MAPK phosphorylation in L-02 cells[1].3,4-Dimethoxycinnamic acid decreases the expression levels of superoxide dismutase, catalase and phospholipid hydroperoxide gluthione peroxidase, and downregulates the levels of Bax/Bcl-2 and the cleaved forms of caspase-3 in a dose- and time-dependent manner[1].
