Structure of cyclic RGD peptides targeting GPIIb/IIIa receptors on activated platelets, and their corresponding ternary ligand 99mTc complexes [99mTc(HYNIC-RGD)(tricine)(TPPTS)] (DMP444: RGD = 6-CA-DMP757, and CA = 6-aminocaproic acid; P4-DMP444: RGD = PEG4-DMP757, and PEG4 = 15-amino-4,7,10,13-tetraoxapentadecanoic acid).
