Rezumat

Four coordination compounds of iron(III) with ligands based on hydrazine and sulfadiazine: [Fe(dig)]Cl3·2H2O (I) (dig-semicarbazide diacetic acid dihydrazide), [Fe(HL)SO4] (II) (НL - sulfadiazine), [Fe(H2L1)(H2O)2](NO3)3·5H2O (III) (H2L1-2,6-diacetylpyridine bis(nicotinoylhydrazone) and [Fe(H2L2)(H2O)2](NO3)3·1.5H2O (IV) (H2L2 - 2,6-diacetylpyridine bis(isonicotinoylhydrazone) were synthesized. The spectroscopic and structure characterisation, as well as their biological properties, are presented. All tested coordination compounds, caused an inhibitory effect on the biosynthesis of hydrolases of the producer Aspergillus niger CNMN FD-10. The effect increased with the raise of the concentration from 5 mg/L to 15 mg/L. The complexes largely inhibited cellobiohydrolase and less- β-glucosidase. The inhibitory effect of the coordination compounds was quite similar in the case of endoglucanase and xylanase. Compound I, containing both chloride ions and dig, demonstrated a stronger inhibitory effect, while compound III, containing NO3 - ions, showed the weakest inhibitory action.
