NCIt definition : A second generation ATP-competitive anthrapyrazolone c-Jun N terminal kinase (JNK)
inhibitor with potential antineoplastic activity. Based on the chemistry of SP600125,
another anthrapyrazolone inhibitor of JNK, CC-401 competitively binds the ATP binding
site of JNK, resulting in inhibition of the phosphorylation of the N-terminal activation
domain of transcription factor c-Jun; decreased transcription activity of c-Jun; and
a variety of cellular effects including decreased cellular proliferation.;
