Publication number: 20130144035Abstract: The present application discloses a new multivalent peptide ligand specifically targeting polymorphonuclear leukocytes (PMNs) with favorable pharmacological parameters to monitor sites of inflammation for imaging. The detailed synthesis, characterization, and pharmacological evaluation of the ligands are reported here. Two separate peptide binding ligands for formyl peptide and tuftsin receptors were chosen to link together based on the high expression levels of the two receptors on activated PMNs The heterobivalency and pegylated links were incorporated in the structural design to improve the sensitivity of the detection and to improve the bioavailability along with blood clearance profile, respectively. Two chemical constructs: cFLFLF-(PEG)n-TKPPR-99mTc (n=4, 12) were evaluated in vitro with human PMNs for binding affinity and bioavailability. As a result, FLFLF-(PEG)12-TKPPR99mTc was found to have more favorable pharmacological properties and was therefore used for further in vivo studies.Type: ApplicationFiled: April 21, 2011Publication date: June 6, 2013Inventors: Dongfeng Pan, Stuart S.
