Synthesis, characterization, and antioxidant/cytotoxic activity of new chromone Schiff base nano-complexes of Zn(II), Cu(II), Ni(II) and Co(II)

New less toxic zeolite‐encapsulated Cu(II) complex nanomaterial for dual applications in biomedical field and wastewater remediation

“…Moreover, the increase in delocalization of π‐electrons over the chelate ring leads to an increase in the lipophilic nature of the complex. This aids diffusion of the chelate into the lipid membrane and prevents new growth of microorganisms . In the case of Cu II ‐complex/NaY, the electrostatic attraction between the positive charge of Cu 2+ and the negative charge of microbial cell membranes interferes with the permeability of the membrane and is followed by the penetration of the material particles into the cell.…”

“…In the case of Cu II ‐complex/NaY, the electrostatic attraction between the positive charge of Cu 2+ and the negative charge of microbial cell membranes interferes with the permeability of the membrane and is followed by the penetration of the material particles into the cell. In addition, the crystal size is an important factor in increasing penetration of complexes into lipid membranes. As shown from XRD analysis, Cu II ‐complex/NaY is characterized by a nanometric size with respect to pure Cu II ‐complex, which gives further explanation as to the high anti‐microbial activity against the tested bacteria and fungi.…”

“…TEM results show that Cu II ‐complex/NaY is characterized with small rod morphology with smaller diameter with respect to Cu II ‐complex. This increases the facility of its uniform penetration and distribution into tumour cells …”

“…Synthesis and spectroscopic investigation of both chromone‐based and isatin‐based complexes have attracted particular interest as a result of the importance of these compounds and their diverse applications involving anti‐microbial, anti‐oxidant, anti‐viral, anti‐tumor, anti‐HIV and other properties …”

Synthesis and Fundamental Characterization of Diverse Properties of Biocompatible Cd (II) Phosphor Complex for Cytotoxic Activity and Latent Fingerprint Detection

“…Moreover, the NMR spectrum of complex did not register any signal corresponding to NH proton of ligand (11.1 ppm) (Figure S3). This indicated that the ligand adopted the thio‐enol form, followed by deprotonation prior to coordination with the Cd (II) ion. The signals corresponding to the protons of aromatic moieties of the ligand and its phosphor complex were observed as multiplets in the range of 7.57–6.66 ppm .…”
