Übersicht

Information

Cucurbitacin IIb (CuIIb, Dihydrocucurbitacin F, 25-deacetyl hemslecin A) inhibits phosphorylation ofSTAT3,JNKandErk1/2, enhances the phosphorylation ofIκBandNF-κB, blocks nuclear translocation ofNF-κBand decreases mRNA levels ofIκBαandTNF-α. Cucurbitacin IIb exhibits anti-inflammatory activity and inducesapoptosis. Cucurbitacin IIb is isolated fromHemsleya amabilis.
