Description: HA14-1 is a potent Bcl-2 inhibitor with potential anticancer activity. HA14-1 induces apoptosis in various human cancer cells. HA14-1 suppressed NF-kappaB activation through inhibition of phosphorylation and degradation of IkappaBalpha. This inhibition was correlated with suppression of NF-kappaB-dependent gene products (c-myc, cyclin D1, cox-2, and IAP-1). Additionally, HA14-1 also markedly sustained TNF-alpha-mediated JNK activation.

Additional Information

HA14-1 is a novel cell-permeable low molecular weight Bcl-2 ligand which antagonizes its function and induces apoptosis. In HL-60 cells 50 µM HA14-1 effectively induced apoptosis associated with loss of mitochondrial membrane potential and activation of caspases -9 and -3.
