Radiolabeled γ-AApeptides: a new class of tracers for positron emission tomography†
Abstract
A γ-AApeptide-based tracer for positron emission tomography imaging of integrin αvβ3 is reported. Despite its shorter sequence and linear nature, this tracer had comparable integrin αvβ3 binding affinity to the cyclic arginine-glycine-aspartic acid peptide but significantly higher resistance to enzymatic degradation and better stability.
