Normal (non-cancerous) Cytotoxicity Vero: IC50=65.03µg/mL
Target Not available
Affinity Not available
Mechanism The perceived cancer cell-selective killing of both peptides P1 and P2 seems to stalk from cationic peptides and the electrostatic interactions between the anionic lipids of cancer cells on account of specific binding between integrins proteins and N (APN/CD13) ligand-receptor on the cancer cell membrane and the presence of binding RGD and NGR motifs in peptides.
