CUCURBITACIN I Chemical Properties,Uses,Production
Description
Cucurbitacin I is a naturally occurring tetracyclic triterpenoid compound with a variety of physiological effects, including induction of apoptosis and blockade of cell cycle progression in various cancer cells. It has also been shown to have anti-angiogenic activity. Cucurbitacin I inhibits the phosphorylation of vascular endothelial growth factor receptor-2 and fibroblast growth factor receptor-1, which are key regulators of endothelial cell function and angiogenesis. Therefore, Cucurbitacin I is considered a potential angiogenesis inhibitor candidate for cancer therapy[1].
Uses
Cucurbitacin I can be useful in the study of edible vitalmelon fruit extract and adipogenesis.
Definition
ChEBI: Cucurbitacin I is a cucurbitacin that is 9,10,14-trimethyl-4,9-cyclo-9,10-secocholesta-2,5,23-triene substituted by hydroxy groups at positions 2, 16, 20 and 25 and oxo groups at positions 1, 11 and 22. It has a role as a plant metabolite and an antineoplastic agent. It is a cucurbitacin and a tertiary alpha-hydroxy ketone.
Biological Activity
Selective inhibitor of STAT3/JAK2 signaling. Inhibits the activation of STAT3 and JAK2 and displays no activity on Src, Akt, ERK and JNK. Suppresses phosphotyrosine levels of STAT3, inhibits STAT3 DNA binding and STAT3-mediated gene expression. Induces apoptosis in cell lines expressing constitutively active tyrosine-phosphorylated STAT3.
Biochem/physiol Actions
Cucurbitacin I (JSI-124) is a novel selective inhibitor of the janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway with anti-proliferative and anti-tumor properties.
storage
Store at -20°C
