Journal ArticleDOI
Experimental and quantum computational study of two new bridged copper(II) coordination complexes as possible models for antioxidant superoxide dismutase: Molecular structures, X-band electron paramagnetic spectra and cryogenic magnetic properties
Yogendra Singh,Ram N. Patel,Satish Kumar Patel,Abhay K. Patel,Neetu Patel,R Singh,Ray J. Butcher,Jerry P. Jasinski,Angel Gutiérrez +8 more
TL;DR: In this article, two bridged copper(II) coordination complexes with NNO donor ligands were characterized using a dual approach comprising experimental and quantum computational studies, and the magnetic exchange coupling constant (J) between the Cu(1)⋯Cu(2) centers for 1 and 2 were determined to be J
Journal ArticleDOI
Varying structural motifs, unusual X-band electron paramagnetic spectra, DFT studies and superoxide dismutase enzymatic activity of copper(II) complexes with N′-[(E)-phenyl(pyridin-2-yl)methylidene]benzohydrazide
Ram N. Patel,Yogendra Singh,Yogendra Singh,Abhay K. Patel,Neetu Patel,R Singh,Ray J. Butcher,Jerry P. Jasinski,Enrique Colacio,Maria A. Palacios +9 more
TL;DR: A diverse set of new copper(II) complexes with N′-[(E)-phenyl(pyridin-2-yl)methylidene]benzohydrazide have been designed and synthesized as possible models for antioxidant superoxide dismutase mimics as discussed by the authors.
Journal ArticleDOI
Unprecedented tetranuclear complexes with “weighing balance shaped” topology: single crystal structures, unusual EPR spectra, magnetic properties and antioxidant activity
Yogendra Singh,Ram N. Patel,Yogendra Singh,Abhay K. Patel,Neetu Patel,R Singh,Ray J. Butcher,Jerry P. Jasinski,Enrique Colacio,Maria A. Palacios +9 more
TL;DR: The antioxidant superoxide dismutase measurements indicate that the unprecedented tetranuclear copper complexes behave as superoxide Dismutase mimics.
Journal ArticleDOI
Supramolecular assemblies of new pseudohalide end-to-end bridged copper(II) complex and molecular structural variety of penta and hexa-coordinted metal(II) complexes with hydrazido-based ligand
Yogendra Singh,R.N. Patel,S. K. Patel,R.N. Jadeja,Alok Patel,Neetu Patel,Hetal Roy,P. Bhagriya,R Singh,Ray J. Butcher,Jerry P. Jasinski,Santiago Montero Herrero,Miguel Cortijo +12 more
TL;DR: In this paper, three new mononuclear [Ni(HL)(NO3)(H2O)]NO3 and one binuclear end-to-end thiocynate bridged [Cu2( μ -SCN)2(L)2], C30H24Cu2N8O2S2, 4 complexes have been synthesized and characterized by physico-chemical techniques.
Journal ArticleDOI
P44 Validation of a pedometer to measure daily physical activities in COPD patients
AD Alahmari,Beverly Kowlessar,A R C Patel,Alexander J. Mackay,R Singh,GC Donaldson,JA Wedzicha +6 more
TL;DR: Whether step-counts measured by a pedometer (Yamax Digi-Walker SW-200) were sufficiently correlated with other measures of physical activity prospectively, to show that the device can be used in COPD patients was determined.
