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

In Vitro

Phellodendrine chloride (0.6-80 μM, 24 h-14 d) significantly inhibits the proliferation and colony formation ability of KRAS-mutated PANC-1 and MiaPaCa-2 cells and its driven macropinocytosis, while showing no obvious toxicity to KRAS wild-type BxPC-3 cells and normal pancreatic cells HPDE6-c7[1].
Phellodendrine (10-40 μM, 12-24 h) diminishes the albumin (Alb) driven intracellular glutamine level, induces reactive oxygen species generation and causes mitochondrial membrane potential (MMP) depolarization in PANC-1 cells[1].
Phellodendrine chloride (5-40 μM, 0-48 h) induces apoptosis cell death in PANC-1 cells through caspase-dependent mitochondrial intrinsic pathway[1].
Phellodendrine (5-20 μM) chloride activates the p-AMPK/mTOR signalling pathway, as well as autophagy in Caco-2 cells stimulated by H2O2[2].
Phellodendrine chloride (5 μM) attenuates Monosodium urate (MSU) (HY-B2130A)-induced MMP3 production and proteoglycan degradation by inhibiting IL-6/STAT3 pathway in rabbit primary chondrocytes and C28/I2 cells (human normal chondrocytes)[3].
Phellodendrine (0-50 μM) chloride reduces the mRNA expression of MRGPRB3 and responsiveness of MRGPRX2 by altering its structure, is able to decrease Ca2+ levels, phosphorylation levels of CaMK, PLCβ1, PKC, ERK, JNK, p38, and p65, and inhibits the degradation of IκB-α in RBL-2H3 cells[4].
Phellodendrine (25-200 μg/mL, 37 h) chloride increases the survival rate of zebrafish embryos and restores the abnormal heart rate levels[5].
Phellodendrine (50-200 μg/mL, 13 h) chloride reduces the ROS level in zebrafish embryos and inhibits lipid peroxidation[5].
Phellodendrine (100 μg/mL) chloride reverses the expression of AKT and NF-κB3, IKK, COX-2 which were abnormally changed by AAPH (HY-Y0525)-induced oxidative stress in zebrafish embryos[5].
Phellodendrine (2.5-160 μg/mL, 24-48 h) chloride has an anti-MDD effect by regulating the mRNA levels of CHRM1, HTR1A and key targets of the PI3K/Akt signalling pathway (PI3K, Akt, mTOR) in PC12 cells[6].

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

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.
