Original Abstract

Zinc chelates with diethylenetriaminepentaacetic acid (DTPA), ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA) and iminodiacetic acid (IDA) have been prepared and conditions for Zn2+ release have been studied. The prepared Zn2+ chelate complexes are of following compositions: ZnCl2(EDTA), Zn(ClO4)(2) . 6H(2)O (EDTA), ZnCl2(NTA), ZnCl2(NTA)(3)(btc), Zn(ClO4)(2) . 6H(2)O (NTA), ZnCl2 (NDA), Zn(ClO4)(2) . 6H(2)O (NDA), ZnCl2(NDA)(3)(btc). (H(3)btc = 1,3,5-benzenetricarboxylic acid). All variants of Zn2+ complexes were diluted to the concentration range 0-1420 mu M and the absorbance spectra in the range of 230-330 nm were measured. The antimicrobial properties of Zn2+ complexes were studied by the method of the growth curves of the bacteria cultures Staphyloccocus aureus. The 50% inhibitory concentration was determined to 500 mu M of each Zn2+ complex. It has been found that the Zn2+ complexes showed increased antimicrobial effect on Staphyloccocus aureus.
