Cucurbitacin E (CuE), a potent member of triterpenoid family isolated from plants, has been confirmed as an antitumor agent by inhibiting proliferation, migration, and metastasis in diverse cancer. Cucurbitacin E nhibits OS tumor growth and invasion through inhibiting the PI3K/Akt/mTOR signaling pathway. CuE can be considered to be a promising anticancer agent for OS. Cucurbitacin E exerts anti-inflammatory actions. It inhibited both COX enzymes with more selectivity toward COX-2. CuE has been reported to possess anti-inflammatory and anti-tumorigenic properties mediated by its action on the cellular cytoskeleton, on mitotic pathways as well as on cellular autophagy.

Sample Use Guides

In Vivo Use Guide

Cucurbitacin E was intra-peritoneally administered to mice at the dose of 30 and 60 mg/kg.

Route of Administration: Intraperitoneal

In Vitro Use Guide

Cucurbitacin E at low concentrations (3-50 nmol/l) inhibited the growth of HL-60 cells, which was associated with G2/M cell-cycle arrest, decrease in the levels of cyclin-dependent kinase1, and increase in the levels of p21. Cucurbitacin E at high concentrations (1-10 mol/l) induced apoptosis of HL-60 cells and activation of caspase-3, caspase-8, and caspase-9
