PSMA-617 TFA

PSMA-617, also know as vipivotide tetraxetan, is a ligand used to make 177Lu-PSMA-617, which is a radioactive molecule to fight cancer. PSMA617 possesses a small peptide, which was designed to target prostate-specific membrane antigen (PSMA) . PSMA617 demonstrates high radiolytic stability for at least 72 h. PSMA617 has high inhibition potency (equilibrium dissociation constant Ki=2.34±2.94 nM on LNCaP; Ki=0.37±0.21 nM enzymatically determined) . 177 Lu-PSMA-617 offers a potential additional life-prolonging treatment option for men with mCRPC.
