However, our in vitro binding studies demonstrated no significant difference in the binding affinity for the integrin α5 β1 between both diastereomers; thus, for all further experiments, a separation of the radiolabelled diastereomeric products was not carried out.
This compound demonstrated rapid labeling using low peptide amounts, resulting in specific activities of up to 1 TBq/ μmol, very high binding affinity for the integrin α v β3 in a competitive cell binding assay, and good tumor/background ratios in a murine tumor model.
In this work, we describe the synthesis of H-C*RRETAWAC*-OH, its binding affinity for the integrins α v β3, α5 β1, and α IIb β3, and the radiolabelling of the peptide via [F]fluoropropionic acid.
