d-KLA Peptide-d30 (D-(KLAKLAK)2-d30) is a deuterium-labeled form of d-KLA Peptide. This synthetic pro-apoptotic peptide specifically targets mitochondria and induces apoptosis by disrupting the mitochondrial membrane. It activates apoptosis-related biochemical pathways, including the activation of caspase family proteins and PARP (poly ADP-ribose polymerase). Additionally, d-KLA Peptide can be utilized for the delivery of genes or small molecules to enhance anti-tumor effects.
