摘要:
A radioactive diagnostic agent which comprises a physiologically active substance and a radioactive metallic element combined with a compound of the formula: wherein R, R', R 1 and R 2 are each a hydrogen atom or a C 1 -C 3 alkyl group and n is an integer of 0 to 3. The agent is characteristic in having a high stability even after being administered into a human body and showing the substantially the same behavior as the physiologically active substance itself in a human body.

摘要:
A method is provided for preparing a radiolabeled conjugate, which comprises the steps of:
(a) contacting an active ester derivative or a thiol-reactive derivative of the bis-thiosemicarbazone of a 1,2-, 1,3- or 1,4-dicarbonyl compound with a radioisotope solution of reduced pertechnetate or perrhenate or of copper, mercury or lead/bismuth ions, to form a radiolabeled bis-thiosemicarbazone chelate without substantially affecting the active ester or the thiol-reactive function; and (b) reacting the radiolabeled bis-thiosemicarbazone chelate with (i) an amine in the case of an active ester derivative, or (ii) a thiol in the case of a thiol-reactive derivative, to form a radiolabeled conjugate.
Also provided are chelators for radioisotopes, radiolabeling agents for labeling an amine or a thiol, kits and injectable preparations for use therewith, and improved imaging methods for in vivo human use employing the foregoing compositions and methods.
