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.
公式为:##STR1##的复合物,其中R.sub.1-R.sub.14中的每一个独立地选择自羟基、烷基,其中一个或多个碳原子可选择地被杂原子如N、O或S取代,以及苯环,可选择地单取代或双取代于一个取代基,所述取代基选择自--SR.sub.15,--OR.sub.15和--NR.sub.15 R.sub.16的群,其中R.sub.15和R.sub.16独立地选择自H和烷基;或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的每一个组合独立地可以取在一起形成一个环状烷基,其中一个或多个碳原子可选择地被杂原子取代,而Ga是一种放射性镓同位素,以及从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脂溶性,应该对心肌灌注成像有用。
