Apoptosis

CHMFL-48, an orally active inhibitor of BCR-ABL kinase, demonstrates efficacy against both the wild-type (wt) and various imatinib-resistant mutants. It exhibits potent inhibitory activity, with IC 50 values of 1 nM for the ABL wild-type and 0.8 nM for the ABL T315I mutant. CHMFL-48 operates by inhibiting the autophosphorylation of both wild-type and mutant BCR-ABL, affecting downstream signaling mediators including STAT5 and CRKL. This disruption leads to cell cycle arrest and triggers apoptosis. Given its properties, CHMFL-48 is a promising candidate for research on chronic myeloid leukemia (CML).

Cyy-272 is an orally active JNK inhibitor with IC50 values of 1.25, 1.07, and 1.24 μM against JNK1, JNK2, and JNK3, respectively. It exerts anti-inflammatory effects by inhibiting the phosphorylation of JNK, thereby alleviating acute lung injury (ALI) induced by lipopolysaccharide (LPS). Moreover, Cyy-272 significantly reduces inflammation in cardiomyocytes and cardiac tissues caused by high lipid concentrations, further mitigating resultant cardiac hypertrophy, fibrosis, and apoptosis. Cyy-272 is utilized in the study of obesity-related myocarditis.

IHMT-MST1-39 is an orally effective MST kinase inhibitor with IC50 values of 42 nM for MST1 and 109 nM for MST2. It activates the AMPK signaling pathway in hepatocytes and inhibits apoptosis in pancreatic β cells. Additionally, IHMT-MST1-39 improves type 1 diabetes in mice induced by Streptozotocin.
