“… The stability and effect of its inhibition need to be further explored and applied. Al-Saidi et al, 2022 Mercaptoethanol The effect of mercaptoethanol on inhibiting the activity of fatty chlorination enzyme is very obvious. Its application in the actual production process is less, and its side effects are not clear, which needs to be further explored.…”

“…This can be attributed to the bioactive molecules such as phenolics, flavonoids, terpenoids, and ginkgolides that are present in the GB extract that is involved in the bioreduction process. In Figure 7 , FT-IR of GB leaf extract shows the presence of –CH stretching vibrations of –CH 3 or –CH functional groups at 2958 cm −1 [ 58 ], O–H stretching at 3390 cm −1 , C–O stretching and carboxyl C=O at 1378 cm −1 and 1720 cm −1 , respectively, alkylphenols (1078 cm −1 ), and aromatic C=C (1632 cm −1 ) [ 5 , 59 , 60 , 61 , 62 , 63 ]. The peaks at 1632 and 1638 cm −1 were for O–H, C–O, and C=O as functional groups of GB extract.…”

The present study aimed to estimate the antiviral activities of Ginkgo biloba (GB) leaves extract and eco-friendly free silver nanoparticles (Ag NPs) against the MERS-CoV (Middle East respiratory syndrome-coronavirus) and HCoV-229E (human coronavirus 229E), as well as isolation and identification of phytochemicals from GB. Different solvents and high-performance liquid chromatography (HPLC) were used to extract and identify flavonoids and phenolic compounds from GB leaves. The green, silver nanoparticle synthesis was synthesized from GB leaves aqueous extract and investigated for their possible effects as anti-coronaviruses MERS-CoV and HCoV-229E using MTT assay protocol. To verify the synthesis of Ag NPs, several techniques were employed, including X-ray diffraction (XRD), scan, transmission electron microscopy, FT-IR, and UV–visible spectroscopy. The highest contents of flavonoids and phenolic compounds were recorded for acetone, methanol, and ethanol as mixtures with water, in addition to pure water. HPLC flavonoids were detected as apegenin, luteolin, myricetin, and catechin, while HPLC phenolic compounds were pyrogallol, caffeic acid, gallic acid, and ellagic acid. In addition, our results revealed that Ag NPs were produced through the shift from yellow to dark brown. TEM examination of Ag NPs revealed spherical nanoparticles with mean sizes ranging from 5.46 to 19.40 nm and an average particle diameter of 11.81 nm. A UV–visible spectrophotometric investigation revealed an absorption peak at λ max of 441.56 nm. MTT protocol signified the use of GB leaves extract as an anti-coronavirus to be best from Ag NPs because GB extract had moderate anti-MERS-CoV with SI = 8.94, while had promising anti-HCov-229E, with an SI of 21.71. On the other hand, Ag NPs had a mild anti-MERS-CoV with SI = 4.23, and a moderate anti-HCoV-229E, with an SI of 7.51.

“…The phenolic (O-H) of the H 2 L disappeared in the Cr(II) and Cu(II) complexes, showing proton replacement during complex formation. The three characteristic peaks of υ(NH) at 3457, υ as (SO 2 ) at 1384 cm −1 and υ sy (SO 2 ) at 1156 cm −1 in the spectra of the Cr(II) and Cu(II) micro-complexes and their free ligand all appear at the same position, excludes the coordination through the NH and SO 2 groups 42 . The new bands in the IR spectra of the prepared compounds at 520-528 and 570-573 cm −1 are ascribed to (M-N) and (M-O), respectively.…”

The primary objective of this study was to describe the cytotoxicity on HEPG-2 cells and to study the COVID‑19 activities of the novel H2L ligand and its Cr and Cu nano-complexes. As well as exploring the chemistry of the prepared nano-complexes. In this paper novel Schiff base, N-(4, 6-dimethyl pyrimidin-2-yl)-4-(((2-hydroxyl naphthalene-1-y l) methylene) amino) benzene—sulfonamidesulfonyl) amide has been synthesized. The novel Schiff base H2L is used to synthesize novel nano and micro-complexes with CrCl2.6H2O and CuCl2.2H2O. The prepared ligand and micro complexes were interpreted by different spectroscopic techniques. The nano-sized Cr and Cu complexes were synthesized in an environmentally friendly manner using Coriandrum sativum (CS) media extract in ethanol. The structure, morphologies and particle size of the nano-sized complexes were determined using FT-IR, TEM, and PXRD. The results showed that the nano-domain complexes are on the Sub-nano scale. Furthermore, using TGA, we studied the effect of heat on the size of newly prepared nano-complexes. Experimental data were supported by DFT calculations. The findings revealed that the metal complexes investigated are more stable than the free ligand H2L. The antitumor activity was examined before and after heating the nano-complexes at 200 °C. The results reveal the Cr nano complex, after heating, exhibited strong antitumor activity with IC50 value (3.349 μg/ml). The tested Cu nano-complex shows good DNA cleavage. The liver cancer and COVID19 proteins were examined using molecular docking to identify the potential binding energy of inhibitors.
