摘要: 用pH电位法测定了在生理条件下(37℃,I=0.15mol/LNaCl)7-氧杂双环-[2,2,1]庚-5-烯-2,3-二羧酸(OHDA)与各种典型氮基酸和锌、铜生成三元混配配合物的生成常数.模拟计算表明,作为药物配体的OHDA确可影响体内复杂的低分子量金属配合物的平衡,并且扰乱体内锌的分布,改变各种含锌酶的活性和功能.

Abstract: The ternaty complex formation constants of 7-oxabicyclo-[2,2, 1]-hept-5-ene-2,3-dicar-boxylic acid (OHDA) with several typical amino acids and Zn(Ⅱ), Cu(Ⅱ) were potentiometrically determined under physiological conditions(37℃, 0. 15 mol/L NaCl). The calculation of mixed ligand complex constants of OHDA shows that the OHDA and amino acids both share the great benefit from the formation of the mixed complexes. Computer simulation of blood plasma model indicates that OHDA acting as a drug ligand does participate in the complicate biological equilibrium of low molecular weight metal complexes disturbing the distribution of essential metal ions--zinc which propably results in changing the activity and function of crucial zinc--containing enzymes. Meanwhile, attention must be paid to the effect of administering OHDAon Cu(Ⅱ) ion balance.
