Eupatorin is an orally active flavonoid with antiproliferative and vasodilatory properties. Eupatorin downregulates the expression levels of NF-κB, MMP9, IL-1β and TNF-α. Eupatorin induces apoptosis, G2/M phase cell cycle arrest, and reactive oxygen species (ROS) production. Eupatorin modulates the activities of muscarinic receptors and β-adrenergic receptors; inhibits sarcoplasmic reticulum calcium release and calcium channels; and activates the NO/sGC/cGMP pathway, indomethacin-sensitive pathway, and potassium channel pathway. Eupatorin exerts cytotoxic effects on cancer cell lines, and is metabolized by CYP1A1 and CYP1 family enzymes to form metabolites with antiproliferative activity. Eupatorin can be used in research related to breast cancer, hypertension, and leukemia.

In Vitro

Eupatorin (0.16-20 μg/mL; 24-72 h) inhibits proliferation of mouse breast cancer 4T1 cells in a time-dependent manner, with IC₅₀ values of >20 μg/mL at 24 h, 6.00 μg/mL at 48 h, and 5.00 μg/mL at 72 h^[1].
Eupatorin (0.001-100 μM; 96 h) potently inhibits proliferation of MDA-MB-468 cells with an IC₅₀ of 0.5 μM, while being far less active in MCF-10A cells with an IC₅₀ of 50 μM; its antiproliferative effect in MDA-MB-468 cells is reversed by CYP1 inhibition^[3].
Eupatorin (10 μM; 48 h) induces G₂/M phase arrest in MDA-MB-468 cells, an effect reversed by CYP1 inhibition, while it does not affect the cell cycle of MCF-10A cells^[3].
Eupatorin (0.1-100 μM; 72 h) potently inhibits viability in HL-60, U937, and Molt-3 human leukemia cell lines with an IC₅₀ of ~5 μM after 72 h of treatment^[4].
Eupatorin (3-30 μM; 6-24 h) induces apoptosis in HL-60, U937, and Molt-3 human leukemia cell lines via G₂-M cell cycle arrest, nuclear fragmentation, DNA laddering, and phosphatidylserine externalization, with 3 μM eupatorin for 24 h driving significant increases in sub-diploid apoptotic cells^[4].
Eupatorin (1-10 μM; 6-24 h) induces dose- and time-dependent activation of initiator (caspase-8, -9) and executioner (caspase-3/7, -6, -4) caspases, as well as PARP cleavage, in HL-60, U937, and Molt-3 human leukemia cell lines, with eupatorin-induced apoptosis dependent on caspase activation^[4].
Eupatorin (1-3 μM; 24 h) activates the intrinsic mitochondrial apoptotic pathway in HL-60, U937, and Molt-3 human leukemia cell lines via release of cytochrome c, AIF, and Smac/DIABLO, modulation of Bcl-2 family proteins, and Bax translocation/cleavage^[4].
Eupatorin (3-10 μM; 1-24 h) activates the ERK1/2 and JNK/SAPK MAPK pathways in HL-60 human leukemia cells within 1-2 h, with JNK/SAPK activation essential for eupatorin-induced apoptosis^[4].
Eupatorin (1-10 μM; 6-24 h) induces ROS generation (peroxides and superoxide) in HL-60 and Molt-3 human leukemia cells, with ROS generation essential for eupatorin-induced apoptosis in Molt-3 cells^[4].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
