Journal ArticleDOI
Synthesis, characterization, optical band gap, in vitro antimicrobial activity and DNA cleavage studies of some metal complexes of pyridyl thiosemicarbazone
TL;DR: In this paper, a new series of Cr(III), Mn(II), Ni (II), Zn(II) and Hg(II)-clusters of Schiff-bases derived from the condensation of 4-(2-pyridyl)-3-thiosemicarbazide and pyruvic acid (H 2 PTP) have been synthesized and characterized by spectroscopic studies.
Journal ArticleDOI
Synthesis, characterization, catalytic, DNA binding and antibacterial activities of Co(II), Ni(II) and Cu(II) complexes with new Schiff base ligand
TL;DR: Examination of synthesized complexes against the human cancer cell lines MCF-7 and HepG-2 were published in comparison with positive controls in the viability assay of vinblastine and colchicine and DPPH free radical-scavenging assays determine the in vitro antioxidant activity of all complexes.
Journal ArticleDOI
Co(II), Cu(II), Cd(II), Fe(III) and U(VI) complexes containing a NSNO donor ligand: Synthesis, characterization, optical band gap, in vitro antimicrobial and DNA cleavage studies
TL;DR: In this article, a new series of Schiff-bases derived from 4-(2-pyridyl)-3-thiosemicarbazide and pyruvic acid (H 2 PTP) have been synthesized and characterized by spectroscopic studies.
Journal ArticleDOI
Synthesis, characterization, molecular modeling and antioxidant activity of (1E,5E)-1,5-bis(1-(pyridin-2-yl)ethylidene)carbonohydrazide (H2APC) and its zinc(II), cadmium(II) and mercury(II) complexes
TL;DR: In this article, a new series of Zn(II), Cd(II) and Hg(II)-complexes of (1E,5E)-1,5-bis(1-(pyridin-2-yl)ethylidene)carbonohydrazide (H 2 APC) have been prepared and characterized by elemental analyses, spectral (IR, UV-visible, mass and 1 H NMR) as well as magnetic and thermal measurements.
Journal ArticleDOI
Synthesis, characterization, molecular modeling and antimicrobial activity of 2-(2-(ethylcarbamothioyl)hydrazinyl)-2-oxo-N-phenylacetamide copper complexes.
TL;DR: Six Cu(II) complexes of 2-(2-(ethylcarbamothioyl)hydrazinyl)-2-oxo-N-phenylacetamide (H(3)APET) have been prepared and characterized by elemental analyses, spectral as well as magnetic and thermal measurements, which revealed that the ligand acts as ON bidentate, ONS tridentate or ONNS tetradentate forming structure.
