Cyy-272 is an orally active JNK inhibitor with IC 50 values of 1.25 μM for JNK1 , 1.07 μM for JNK2 , and 1.24 μM for JNK3. Cyy-272 exerts anti-inflammatory effects by inhibiting JNK phosphorylation, thereby alleviating acute lung injury (ALI) induced by lipopolysaccharide. Additionally, Cyy-272 significantly reduces inflammation in cardiomyocytes and cardiac tissue induced by high lipid concentrations, further mitigating cardiac hypertrophy, fibrosis, and apoptosis. Cyy-272 can be used in the study of obese cardiomyopathy.
