CUCURBITACIN B Chemical Properties,Usage,Production

Description

Cucurbitacin B is a tetracyclic triterpenoid that has been shown to have a strong antitumor activity.

Chemical Properties

White solid

Uses

Cucurbitacin B hydrate has been used:

as a signal transducer and activator of transcription 3 (stat3) inhibitor to determine its effect on the expression of human lysosomal acid lipase (hLAL) in myeloid-derived suppressor cells (MDSCs).
as an ecdysone receptor (EcR) antagonist injection to lower the levels of 20-hydoxyecdysone (20E) signaling in butterflies.
to determine its effect on the cell viability of pancreatic cancer cell lines.

Definition

ChEBI: A cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 5 and 23; a hydroxy function at C-25 is acetylated.

Biochem/physiol Actions

Cucurbitacin B is a triterpenoid constituent of Cucurbitaceae plant species. Cucurbitacin B inhibits proliferation in a wide variety of tumor cell lines (IC50 15-30 nM) by inducing apoptosis and inducing cell cycle arrest at G2/M phase. Although the mechanism of action is unclear, Cucurbitacin B inhibits STAT 3 phosphorylation and expression levels and has been shown to block JAK2 activity. Curcubitacin B also inhibits the transcriptional activity of HIF1a and Nf-KB. Curcubitacin B is structurally similar to the JAK inhibitor Curcubitacin I.
