“…Both complexes in DMSO exhibited positive results for S. aureus and E. coli , with MIC (minimum inhibitory concentration) values of 4.50 µg·mL −1 , and the concentration range tested was 3.20 to 24.5 µg·mL −1 . These results are similar to those found in the previous works, as shown in Table 2 , and better than those found in Solanki et al [ 47 ], which describes the carboxylates and pyrazole containing mixed ligand copper(II) and cobalt(II) complexes synthesis, which had MIC activity of 200 µg·mL −1 against S. aureus , and E.coli . Reports on the antimicrobial activities of Pinus resin [ 48 , 49 ], demonstrated that the Pinus resin is insoluble in water, and the pigments (Cu-abietate and Co-abietate) show hydrophobic properties.…”

Co-abietate and Cu-abietate complexes were obtained by a low-cost and eco-friendly route. The synthesis process used Pinus elliottii resin and an aqueous solution of CuSO4/CoSO4 at a mild temperature (80 °C) without organic solvents. The obtained complexes are functional pigments for commercial architectural paints with antipathogenic activity. The pigments were characterized by Fourier-transform infrared spectroscopy (FTIR), mass spectrometry (MS), thermogravimetry (TG), near-edge X-ray absorption fine structure (NEXAFS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and colorimetric analysis. In addition, the antibacterial efficiency was evaluated using the minimum inhibitory concentration (MIC) test, and the antiviral tests followed an adaptation of the ISO 21702:2019 guideline. Finally, virus inactivation was measured using the RT-PCR protocol using 10% (w/w) of abietate complex in commercial white paint. The Co-abietate and Cu-abietate showed inactivation of >4 log against SARS-CoV-2 and a MIC value of 4.50 µg·mL−1 against both bacteria Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The results suggest that the obtained Co-abietate and Cu-abietate complexes could be applied as pigments in architectural paints for healthcare centers, homes, and public places.

“…The color intensity indirectly reflects the health of cells and functional mitochondria . Because of the simplicity and effectiveness of this protocol MTT assay is widely used for assessing cytotoxicity of various therapeutic agents, metal complexes, and nanoparticles . In our study interaction of ion gel with adherent A549 cells did not account for any mortality till the highest dose (200 μg mL −1 ) (Figure ).…”

Self‐polymerization of optimized amount of 2‐hydroxyethylmethacrylate (HEMA) in a natural deep eutectic solvent (NADES) is obtained by the complexation between choline chloride and fructose (ChCl:Fruc. 2:1) in the presence of indomethacin, an anti‐inflammatory drug resulted formation of a drug‐immobilized ion gel. The ion gel thus obtained is found to be stable in gastrointestinal fluid pH (GIF) and sustained release in simulated lower intestinal fluid for 20 h (88% release) at pH 6.8 and 96% release at pH 7.4 for 15 h (colon & blood pH) at physiological human body temperature (37 °C) of the drug is recorded. The drug can be stored in the gel matrices at room temperature for long durations such as 6 months without any degradation. The ion gel of poly‐HEMA obtained in the NADES does not appear to inhibit the growth of mammalian cells in vitro and is found to be compatible to human blood thus implying toward their potential for therapeutic applications as pH‐sensitive hydrophobic drug carrier for oral application as well as in tissue engineering.

“…For example, they have been widely exploited for luminescence [1][2][3][4], antitumor [5][6][7][8], antibacterial [9][10][11][12], gas storage [13], as well as magnetic [14][15][16][17]. Meanwhile, metal complex materials have also been attracted interests due to their excellent catalytic activities for many organic reactions [18][19][20][21][22].…”

Metal-organic complex hybrid materials constructed from carboxylate ligands and hydrazone ligands have exhibited potential application in many fields. In order to enrich the applications of the metaiorganic complex materials, a new hydrazone ligand contains carboxylate group, 2-carboxybenzaldehyde-p-toluenesulfonyl hydrazone (L1), and its Cu(II) complex (C2), have been prepared. The structure of L1 was determined by elemental analysis, IR spectra and single crystal X-ray diffraction, and the composition of Cu(II) complex (C2) has also been determined by elemental analysis, IR and UV spectra. The catalytic activity for A 3 coupling reaction of benzaldehyde, piperidine, and phenylacetylene has been investigated. The results show that Cu(II) complex displays a 100 % selectivity to the product of propargylamine during A 3 coupling reaction and benzaldehyde conversions were 95.3, 94.2, and 93.4 % at 120 °C for 12 h in the first, second, and third reaction cycles, respectively.
