Cucurbitacin IIb is an active component isolated from Hemsleya amabilis, induces apoptosis with anti-inflammatory activity. Cucurbitacin IIb inhibits phosphorylation of STAT3, JNK and Erk1/2, enhances the phosphorylation of IκB and NF-κB (p65), blocks nuclear translocation of NF-κB (p65) and decreases mRNA levels of IκBα and TNF-α.
