CUCURBITACIN I Structural

What is CUCURBITACIN I?

The Uses of CUCURBITACIN I

Cucurbitacin I can be useful in the study of edible vitalmelon fruit extract and adipogenesis.

What are the applications of Application

Cucurbitacin I is a Stat3 and JAK2 inhibitor and antiproliferative agent

Definition

ChEBI: 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.

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
