The binding of metallic ions andthe probability of bridging metallicions with doxycycline hyclate andamino-acids were studied. The proba-bility of formation of binary complexesbetween Zn(Ⅱ), Cu(Ⅱ), Ni(Ⅱ),Co(Ⅱ) and Mn(Ⅱ) ions and doxycyclinehyclate or DL-α-alanine was studiedby the potentiometric method. Theexperimental results showed that stablebinary complexes were formed betweendoxycycline hyclate and certain metal-lic ions,and more stable ternary mixedligand complexes were formed in thepresence of DL-α-alanine....

Theexperimental results showed that stablebinary complexes were formed betweendoxycycline hyclate and certain metal-lic ions,and more stable ternary mixedligand complexes were formed in thepresence of DL-α-alanine. Ionizationconstant of DL-α-alanine, stabilityconstants of certain transition metallicions Zn(Ⅱ), Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ)and Mn(Ⅱ)-DL-α-alanine binary com-plexes, and stability constants of cer-tain transition metallic ions (Zn(Ⅱ),Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ) and Mn(Ⅱ))-doxycycline hyclate-DL-α-alanineternary mixed ligand complexes hadbeen determined in aqueous solutionat 20± 1°C and 0.01 ionic strength(KNO_3) by the potentiometric method.The stability constants of the ternarymixed ligand complexes are higherthan those of the binary complexes;and in the former Cu(Ⅱ)-doxycyclinehyclate-DL-α-alanine system is muchmore stable.
