• Beschreibung

  Cucurbitacin E is a plant-derived triterpene that has diverse biological activities. At a concentration of 10 pM, it reduces MPP⁺-induced death of neuronal PC12 cells through inhibition of autophagy in vitro. Cucurbitacin E inhibits growth of T24 bladder, MDA-MB-468 and MCF-7 breast, PC3 prostate, and colorectal cancer cell lines (IC₅₀s = 50-1,000 nM) through induction of G₂/M arrest and apoptosis. It increases bilirubin binding to human serum albumin (HSA) in human plasma in a dose-dependent manner. Cucurbitacin E also inhibits depolymerization of actin filaments isolated from rabbit skeletal muscle actin and in HeLa cells.

• Chemische Eigenschaften

  white to beige powder

• Verwenden

  Cucurbitacin E has been used as a cofilin inhibitor. It is also used as a F-actin stabilizer to prevent membrane-associated periodic skeleton (MPS) loss and protect from axonal fragmentation.

• Verwenden

  Cucurbitacin E is a biochemical compound from the family of Cucurbitacins. Cucurbitacin E is a highly oxidated steroid consisting of a tetracyclic triterpene. Cucurbitacin E is known to possess broad spectrum of potential anti-inflammatory, antitumor andantioxidant effects.

• Definition

  ChEBI: A cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 1, 5 and 23.

• Allgemeine Beschreibung

  This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG.

• Biochem/physiol Actions

  Cucurbitacin E is a potent inhibitor of actin depolymerization. Cucurbitacin E is more active than jasplakinolide, and has a different mechanism of action, binding to a different site. Cucurbitacin E binds specifically to filamentous actin (F-actin) forming a covalent bond at residue Cys257, but not to monomeric actin (G-actin), stabilizing F-actin, without affecting actin polymerization or nucleation.
