  Preferential Cleavage of a Tripeptide Linkage by Enzymes on Renal Brush Border Membrane To Reduce Renal Radioactivity Levels of Radiolabeled Antibody Fragments

  摘要：

  The obstructive renal radioactivity after injection of antibody fragments/constructs labeled with metallic radionuclides would be improved by liberating a radiometal chelate of urinary excretion from the antibody molecules by enzymes on the renal brush border membrane (BBM). A tripeptide GFK sequence was newly evaluated as an enzyme-cleavable linkage and conjugated to a Tc-99m chelate of an isonicotinic acid derivative of 2-picolylglycine (Tc-99m-IPG). Tc-99m-IPG-glycine was liberated from Tc-99m-IPG-GFK by the enzymes, while Tc-99m-IPG-GK (where the tripeptide GFK was substituted with a dipeptide GK) did not. When injected into mice,Tc- 99m-IPG-GFK-conjugated Fab exhibited lower renal radioactivity levels than directly radioiodinated Fab shortly after injection without reducing the tumor radioactivity levels, due to a release and excretion of Tc-99m-IPG-glycine by enzymes present on the renal BBM. These findings would provide insights to develop antibody fragments/constructs labeled with metallic radionuclides of the clinical relevance for improved renal radioactivity levels.
