Complexes having the formula: ##STR1## where each of R.sub.1 -R.sub.14 is independently selected from the group consisting of hydrogen, alkyl groups in which one or more carbon atoms is optionally substituted by a heteroatom such as N, O or S, and phenyl optionally mono- or di-substituted with a substituent selected from the group consisting of --SR.sub.15,-- OR.sub.15, and --NR.sub.15 R.sub.16, where R.sub.15 and R.sub.16 are independently selected from H and alkyl groups; or each grouping of R.sub.1 and R.sub.2, R.sub.3 and R.sub.4, R.sub.5 and R.sub.6, R.sub.7 and R.sub.8, R.sub.11 and R.sub.12, and R.sub.13 and R.sub.14 may independently be taken together to form a cyclic alkyl in which one or more carbon atoms is optionally substituted by a heteroatom, and Ga is a radioactive gallium isotope, and pharmaceutically acceptable salts thereof prepared from gallium radioiosotopes and ligands such as tetraethylcyclohexyl-bis-aminoethanethiol (BAT-TECH) are disclosed which, because of their high uptake in the heart and lipid-solubility, should be useful for myocardial perfusion imaging.
本发明涉及具有以下式的络合物:##STR1##
其中R.sub.1-R.sub.14中的每个都是独立地从氢,烷基基团中选择,其中一个或多个碳原子可以选择性地被杂原子如N,O或S取代,以及苯基,可选地具有一个或两个取代基,所述取代基从以下群中选择:--SR.sub.15,--OR.sub.15和--NR.sub.15 R.sub.16,其中R.sub.15和R.sub.16独立地选择自H和烷基基团;或者R.sub.1和R.sub.2,R.sub.3和R.sub.4,R.sub.5和R.sub.6,R.sub.7和R.sub.8,R.sub.11和R.sub.12以及R.sub.13和R.sub.14的每个分组可以独立地结合形成一个环烷基,其中一个或多个碳原子可以选择性地被杂原子取代,Ga是一种放射性镓同位素,以及由镓放射性同位素和配体如四乙基环己基双氨乙烷硫醇(BAT-TECH)制备的药学上可接受的盐。由于它们在心脏中的高摄取率和亲脂性,因此应该对心肌灌注成像有用。
