Research Abstract

SA-X is a N-methylated cyclic peptide containing Phe(4-X)(X=Br, I) residue exhibiting potent antitumor activity against triple-negative breast cancer (TNBC). In this study, we designed and synthesized molecular probes useful for the development of molecular targeted chemotherapeutics for TNBC.(1) SA-I was successfully conjugated with biotin-or fluorophore-tagged polyproline rod.(2) Radioiodine-labeled SA-I (SA-[^<125>I]) was synthesized via tin-radioiodine exchange reaction. SA-[^<125>I] showed high accumulation in liver and intestine after administration to in normal and tumor-bearing mice. In addition, SA-[^<125>I] hardly accumulated in tumor.
