特點和優勢

Amino-dPEG4-acid has a primary amine and propionic acid terminating opposite ends of a 16-atoms long (18.0 Å) polyethylene glycol (PEG) spacer. The single molecular weight PEG spacer is discrete (Ð = 1). Moreover, it is highly hydrophilic, and it imparts hydrophilicity to conjugates that incorporate it. Amino-dPEG4-acid is useful in many different applications, including peptide synthesis, surface modification, dendrimer construction, and small molecule modification.

This report describes the synthesis of two cyclic RGD (Arg-Gly-Asp) conjugates, HYNIC-2PEG(4)-dimer (HYNIC = 6-hydrazinonicotinyl; 2PEG(4)-dimer = E[PEG(4)-c(RGDfK)](2); and PEG(4) = 15-amino-4,7,10,13-tetraoxapentadecanoic acid) and HYNIC-3PEG(4)-dimer (3PEG(4)-dimer = PEG(4)-E[PEG(4)-c(RGDfK)](2)), and evaluation of their (99m)Tc complexes [(99m)Tc(HYNIC-2PEG(4)-dimer)(tricine)(TPPTS)] ((99m)Tc-2PEG(4)-dimer: TPPTS = trisodium triphenylphosphine-3,3',3''-trisulfonate)

The ability to switch optical imaging probes from the quenched (off) to the active state (on) has greatly improved target to background ratios. The optimal activation efficiency of an optical probe depends on complete quenching before activation and complete dequenching
