  名称：

  Synthesis and characterization of five-coordinate rhenium(V) and technetium(V) mixed ligand bifunctional complexes carrying the SNS/S or the SNN/S donor atom set. Crystal structure of ReO{[(C2H5)2NCH2CH2N(CH2CH2S)2](p-H2N–PhS)} and ReO{[(CH2)4NCH2CH2NCH2CH2S](p-H2N–PhS)}

  摘要：

  Two parallel series of bifunctional mixed ligand oxorhenium and oxotechnetium complexes containing the SNS/S or the SNN/S donor atom set are synthesized and characterized in this study. The amine bifunctional anchor is positioned on the common monothiolate p-H2N-Ph-SH coligand, which by reacting in equimolar amounts with a tridentate aminethiolate ligand LH2 [LH2:CH3CH2N(CH2CH2SH)(2), (CH3CH2)(2)NCH2-CH2N(CH2CH2SH)(2), (CH2)(4)NCH2CH2NHCH2CH2SH and (CH3CH2)(2)NCH2CH2NH-CH2CH2SH] and the corresponding oxometal precursor, leads to the generation of these series. Two representative members ReO{[(C2H5)(2)NCH2CH2N(CH2CH2S)(2)](p-H2N-PhS)} and ReO{[(CH2)(4)NCH2CH2NCH2CH2S](p-H2N-PhS)} are further characterized by crystallographic analysis. The SNS/S analogs adopt a distorted trigonal bipyramidal geometry, while the SNN/S ones prefer a distorted square pyramidal geometry around the metal. Extrapolation of structure at tracer level is investigated by chromatographic methods and is established only for the SNS/S, but not for the SNN/S compounds. Thus, by this initial evaluation, the applicability of the bifunctional SNS/S (but not the SNN/S) system for tagging biomolecules with Tc-99m is demonstrated. (C) 1999 Elsevier Science S.A.
