Abstract The synthesis of new tetra-kis N- substituted tetra-azamacrocyles was achieved. In the case of tetra amido analogues the best yields were obtained through the use of Schotten - Bauman reaction type in a biphasic system. In the case of tetra-N- ω alkyl carboxylic esters, optimal experimental conditions leading to the desired tetra N-substituted derivatives are described.
The disclosure provides a compound comprising bisphosphonate functional group and chelating agent. The bisphosphonate functional group part has high affinity for bone tissue, and the chelating agent part has high affinity for metal tracer such as radioisotope. The disclosed compound could be rapidly adsorbed onto the bone surface, and could steady emit ionizing radiation. Therefore, the disclosed compound is suitable for bone scanning technology to find abnormalities in bone.
