With the objective of studying conformational and macrocyclic effects selected metal chelates on their peroxidase activities, Cu2+ Fe3+ complexes were synthesized with a derivative ethylenediaminetetraacetic acid o-phenylenediamine (abbreviated as edtaodH2) its new open-chain analogue (edtabzH2). The complex edtaodH2 has peroxidase-like activity, whereas edtabzH2 does not. X-ray study former shows formation dimeric molecule {[Fe(edtaod)]2O} in which each an octahedral coordination is...
A new acyclic bismuth complex (Bi-edtabz) was synthesized from a mixture of solutions the ligand (EDTA-based phenylene) and under acidic conditions. Its anti-virulence properties were evaluated against Escherichia coli O157: H7, Listeria monocytogenes , Pseudomonas aeruginosa Salmonella enterica sub. serovar Typhimurium Staphylococcus aureus . The characterized by NMR, UV-Vis, FTIR, ESI/MS TG. Furthermore, Bi-edtabz at 0.25–1 mM presented better antibiofilm E. H7 S. with values biomass...
The Cu2+, Mn2+, and Fe3+ complexes of a 14 membered macrocycle were synthesized their antioxidant capacities evaluated against ABTS DPPH radicals, with the objective collecting insights into biomimetic role central metal ions. macrocycle, abbreviated as H2L14, is derivative EDTA cyclized 1,4-diamine, moderately flexible macrocyclic frame permits formation [ML14·H2O] chelates octahedral coordination geometries common among characterized by electrospray-ionization mass spectrometry, Fourier...
Glutathione S-transferases are a family of detoxifying enzymes that catalyze the conjugation reduced glutathione (GSH) with different xenobiotic compounds using either Ser, Tyr, or Cys as primary catalytic residue. We identified novel GST in genome shrimp pathogen V. parahaemolyticus FIM- S1708+, bacterial strain associated Acute Hepatopancreatic Necrosis Disease (AHPND)/Early Mortality Syndrome (EMS) cultured shrimp. This new class was named Gtt2. It has an atypical mechanism which water...
With the objective to understand coordination chemistry of bismuth with thiosemicarbazone ligands, five new (III) complexes were synthesized using microwave irradiation. Also, four thiosemicarbazones modified valeric and succinic anhydride characterized through several spectroscopic techniques (NMR 1H 13C, FTIR, UV-Vis, ESI-MS, X-ray). Crystal structure L1 L3 showed an E configuration. In crystal structures, C-S distance is intermediate between a single-bond 1.82 Å double-bond value 1.56 Å;...
