The solid phase procedure was used to prepare two peptide T derivatives in which the 4-[(1,4,8,11-tetraazacyclotetradec-1-yl)methyl]benzoyl unit is linked to their N-terminus. In a human monocyte chemotaxis assay, both chelator-peptide conjugates showed a high binding property to the CD4 receptor, comparable to the parent H-D-Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr-NH2 and its pentapeptide fragment T(4-8)-NH2. These encouraging results make the above cyclam-oligopeptides candidates for the development of the CD4 receptor imaging agents.

Abstract
The solid phase procedure was used to prepare two peptide T derivatives in which the 4-[(1,4,8,11-tetraazacyclotetradec-1-yl)methyl]benzoyl unit is linked to their N-terminus. In a human monocyte chemotaxis assay, both chelator-peptide conjugates showed a high binding property to the CD4 receptor, comparable to the parent H-D-Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr-NH2 and its pentapeptide fragment T(4-8)-NH2. These encouraging results make the above cyclam-oligopeptides candidates for the development of the CD4 receptor imaging agents.File in questo prodotto:
