A series of symmetrical imidazolinium chloride salts bearing secondary N-alkyl substituents were synthesized in good yield by the reaction of N,N′-dialkylethane-1,2-diamines and HC(OEt)3 in the presence of NH4Cl. These salts were characterized by spectroscopic methods. All compounds were tested as enzyme inhibitory agents. These novel symmetrical imidazolinium chloride salts derivatives (3a-h) effectively inhibited the cytosolic hCA I and hCA II, BChE, α-glycosidase and AChE with Ki values in the range of 18.41–121.73 nM for hCA I, 12.50–63.12 nM for hCA II, 3.72–34.58 nM for AChE, 5.50–32.36 nM for BChE, and 94.72–364.51 nM for α-glycosidase, respectively. CA isoenzymes play a crucial roles including acid-base balance homeostasis by excreting and secreting protons (H+) due to the CO2 hydration, HCO3 ? reabsorption mechanisms, and renal NH4 + output. Also, the molecular modeling is an implementation for estimation of the binding proximity of symmetrical imidazolinium chloride salts bearing secondary wingtip groups and their inhibition mechanisms and kinetics in atomic levels at the catalytic domains.
Electrocatalytic CO2 reduction by a cobalt bis(pyridylmonoimine) complex: Effect of acid concentration on catalyst activity and stability
Nie, Weixuan,McCrory, Charles C. L.
supporting information, p. 1579 - 1582 (2018/02/14)
A Co complex with a redox-active bis(pyridylmonoimine) ligand has been prepared and shows catalytic activity for electrochemical CO2 reduction in acetonitrile. Addition of a proton source such as water or trifluoroethanol dramatically improves the activity and stability of the molecular catalyst. The Co complex reduces CO2 to CO selectively at -1.95 V vs. Fc+/0 in the presence of high concentrations of water. The activity of the Co complex for CO2 reduction compares favorably to other molecular Co-based catalysts in acetonitrile solutions.

Synthesis and characterization of bioactive zinc(II) and cadmium(II) complexes with new Schiff bases derived from 4-nitrobenzaldehyde and acetophenone with ethylenediamine
Prakash, Anant,Singh, Bibhesh K.,Bhojak, Narendar,Adhikari, Devjani
experimental part, p. 356 - 362 (2010/08/08)
The new Schiff bases N,N′-bis (4-nitro benzaldehyde) ethylenediamine (L1) and N,N′-bis (acetophenone) ethylenediamine (L2) and its Zn(II), Cd(II) complexes were synthesized and characterized by different physicochemical studies. Vibrational spectra indicate coordination of metal ion through azomethine nitrogen and acetate/nitrate ions. The presence of water molecule in all the complexes has been supported by TG/DTA studies. Mass spectrum explains the successive degradation of the molecular species in solution and justifies ML complexes. Kinetic and thermodynamic parameters were computed from the thermal data using Coats and Redfern method, which confirm first order kinetics. The bioefficacy of the ligands and their complexes have been examined against the growth of bacteria in vitro to evaluate their antimicrobial potential. The results indicate that the ligand and their metal complexes possess notable antimicrobial properties. X-ray powder diffraction determines the cell parameters of the complexes.
