CC-401的生物活性

CC-401 is a second generation ATP-competitive anthrapyrazolone c-Jun N terminal kinase (JNK) inhibitor with potential antineoplastic activity.
IC50 value:
Target: JNK
In vitro: JNK inhibition decreased cytochrome c release, caspase 3 activation (P<0.05), and lipid peroxidation (P<0.05). JNK inhibition also transiently blocked phosphorylation of c-Jun at 60 minutes after reperfusion (P<0.05) without affecting other MAPK signaling, including p-38 and Erk activation [1].
in vivo: In acute disease, CC-401 blocked JNK signaling and reduced proteinuria in the first 24 h. The transient neutrophil influx seen at 3 h of disease was not affected, however. Continued CC-401 treatment suppressed glomerular and tubulointerstitial damage usually seen at 14 days [2]. Administration of CC-401 to rats prior to bilateral renal I/R prevented acute renal failure and largely prevented tubular damage, leucocyte infiltration and upregulation of pro-inflammatory molecules. However, delaying CC-401 treatment until 1 h after reperfusion (after the peak of JNK activation) had no protective effect [3].
