Cyclic polyaza chelators that possess high affinity and specificity for first transition series metal cations exhibit an unanticipated improvement in biological activity when administered as complexes with cations of the alkaline earth metals, Ca(II) and Mg(II), most notably Ca(II). By virtue of this improvement, these complexes are particularly effective in the treatment of pathological conditions, including ischemia and ischemia-reperfusion injury.
具有高亲和力和特异性的环状多氮螯合剂,当与碱土金属阳离子的络合物一起给药时,表现出生物活性的意外改善,其中以Ca(II)和Mg(II)的络合物最为显著,尤其是Ca(II)。由于这种改善,这些络合物在治疗病理条件,包括缺血和缺血再灌注损伤方面特别有效。
