摘要
The invention relates to a technetium-99m complex of the general formula IMAGE (I) wherein Z is a sulphur atom or an amino group of the general formula R17-N-(R18)k, in which k is 0 or 1 and R17 and R18 have the same meanings as the symbols R1-R16; each of the symbols R1-R16 is individually selected from the group consisting of hydrogen, straight or branched, unsubstituted or substituted alkyl having 1-4 carbon atoms, and ACOOH, wherein A is a straight or branched, unsubstituted or substituted alkly group having 0-4 carbon atoms; and R5 together with R6 or R9 together with R10 additionally may form an oxygen atom; Tc represents technetium-99m; t is 0 or 1; and n is 0 or 1; with the provisos that (a) if R15, R16, R17 and/or R18 are/is ACOOH, A is a straight or branched, unsubstituted or substituted alkyl group having 1-4 carbon atoms; (b) at least one of the symbols R1-R18 is ACOOH; and (c) if t is 1, at least two of the symbols R1-R18 are ACOOH; or a pharmaceutically acceptable salt of this compound. The invention further relates to a radiopharmaceutical composition comprising said complex, to the use of this composition for examining the renal function, and to a kit for preparing such a composition.
