Eurycomalactone

Customer Review

Based on 1 Customer Validation

Eurycomalactone is an active quassinoid could be isolated from Eurycoma longifolia Jack. Eurycomalactone is a potent NF-κB inhibitor with an IC₅₀ value of 0.5 μM. Eurycomalactone inhibits protein synthesis and depletes cyclin D1. Eurycomalactone enhances radiosensitivity through arrest cell cycle at G2/M phase and delayed DNA double-strand break repair. Eurycomalactone inhibits the activation of AKT/NF-κB signaling, induces apoptosis and enhances chemosensitivity to Cisplatin (HY-17394).

In Vitro

Eurycomalactone (24, 48 and 72 h) selectively inhibits the viability of A549 and COR-L23 cells Eurycomalactone inhibits the viability of A549 cells with IC₅₀ values of 20.17, 3.77, and 1.90 μM for 24, 48 and 72 hours, respectively. Eurycomalactone inhibits the viability of COR-L23 cells with IC₅₀ values of 25.02, 2.74, and 1.80 μM for 24, 48 and 72 hours, respectively^[1].
Eurycomalactone (2.29-156.3 μM; 24 h; A549 and Calu-1 cells) promotes Non-small cell lung cancer (NSCLC) cells apoptosis^[2].
Eurycomalactone (0-25.05 μM; 24 h; A549 and COR-L23 cells) induces cell cycle arrest at the radiosensitive G2/M phase and induces apoptosis in irradiated Non-small cell lung cancer (NSCLC) cells. Eurycomalactone downregulated the key G2/M regulatory proteins in irradiated Non-small cell lung cancer (NSCLC) cells^[1].
Eurycomalactone (2.5-25 μM; 24 h; A549 cells) suppressed the repair of radiation-Induced DNA double-strand breaks^[1].

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.
