生物活性

Phellodendrine is an orally active plant alkaloid. Phellodendrine inhibits the proliferation of KRAS-mutated pancreatic cancer cells by suppressing macropinocytosis and glutamine metabolism, inducing ROS accumulation and mitochondrial apoptosis. Phellodendrine promotes autophagy by activating the AMPK/mTOR pathway, alleviating intestinal damage in ulcerative colitis. Phellodendrine can alleviate gouty arthritis by inhibiting the IL-6/STAT3 signaling pathway. Phellodendrine suppresses allergic reactions by altering the conformation of MRGPRB3/MRGPRX2 protein, thereby inhibiting the activation of PKC and subsequent downstream MAPK and NF-κB signaling. Phellodendrine inhibits the AKT/NF-κB pathway and down-regulates the expression of COX-2, thereby protecting zebrafish embryos from oxidative stress. Phellodendrine has an anti-major depressive disorder (MDD) effect by down-regulating CHRM1, HTR1A, and the PI3K/Akt signaling pathway[1][2][3][4][5][6].

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.
