Technetium and rhenium complexes of mercapto-containing peptides 1. Tc(V) and Re(V) complexes with mercaptoacetyl diglycine (MAG2) and X-ray structure of AsPh4[TcO(MAG2)]·C2H5OH
diglycine (MAG 2 ) with technetium(V) gluconate in aqueous solution produced [TcO(MAG 2 )] − . A single X-ray structure determination was carried out for the tetraphenylarsonium salt. The dark brown crystals are monoclinic, space group P 2( 1 )/ n , with a =12.478(5), b =14.922(5), c =17.183(9) A and Z =4. The [TcO(MAG 2 )] − ion has a square pyramidal geometry with the technetium atom displaced by 0.756
The present invention provides a compound excellent in accumulation on calcified tissues and ensuring rapid excretion into urine as well as rapid clearance from blood, useful as a diagnostic agent and a therapeutic agent, etc. The compound is a compound having affinity with a calcified tissue represented by the following formula: (AC)a-MC-(LI)b. In the formula, MC is a mother nucleus and represents a residue of a compound having a plurality of functional groups selected from the group consisting of an amino group, an amide group, a hydroxyl group, a thiol group, a thioether group, a sulfonyl group a phosphonyl group, an aldehyde group, a carboxyl group, a carbonyl group, a halogen, and a cyano group; AC is a group having affinity with a calcified tissue; LI is a ligand for binding to a metal atom; and a is an integer of 1 or more and b is 0 or an integer of 1 or more.

The present invention relates to selectively targeting tumoral vasculature in vivo using a human recombinant scFv, L19, to the angiogenesis marker ED-B domain of fibronectin. In preferred embodiments, a complete human IgG1 is employed having the variable regions of L19. In other embodiments is employed a mini-immunoglobulin generated by fusing the scFv L19 to the constant CH4 domain of a secretory IgE isoform that naturally contains a cysteine in its COOH terminal and which forms a covalently linked dimer. Different in vivo behaviour of the antibody formats is exploitable for different diagnostic and/or therapeutic purposes, depending on clinical needs and disease. The antibody molecules may be labelled as described.
