Patent ID: 7887783

Claim:
A radiopharmaceutical compound made by a process comprising: providing a polypeptide sequence set forth in SEQ. ID. No. 1 or a sequence having at least 70% sequence similarity to SEQ. ID. No. 1, wherein the polypeptide comprises a thioether bond between amino acids located at positions 1-18, 4-14, and 5-11, wherein the polypeptide comprises an amide bond between amino acids located at positions 6-19, and, wherein one or more distal moieties according to the structure are covalently bound to the amino acid at position 1, position 2, or, positions 1 and 2 of the polypeptide, and, wherein R 1 and R 2 are each independently a straight or branched, saturated or unsaturated C 1-4 alkyl, and, chelating one or more of the distal moieties with 99m Tc x , ( 99m Tc═O) +3 , ( 99m Tc≡N) +2 , O═ 99m Tc═O) + or ( 99m Tc(CO) 3 ) + , wherein x is a redox or oxidation state selected from the group consisting of +7, +6, +5, +4, +3, +2, +1, 0 and −1, or, a salt, or hydrate thereof.
