In this current paper, fifteen novel sulfonyl hydrazone derivatives have been successfully synthesized and evaluated for antioxidant activity as well as their effects on inhibitory activity toward acetylcholinesterase (AChE). By using 1H NMR, 13C NMR, FT-IR, and high-resolution mass spectrometry methods, the full characterization data of the novel compounds were obtained. The synthesized compounds capacity to inhibition glucosidase and exhibit antioxidant activity were tested in vitro. It was determined that compounds (E)-4-((2-((4-chlorophenyl)sulfonyl)hydrazone)methyl)-2-methoxyphenylfuran-2-carboxylate (21), (E)-2-methoxy-4-((2-(phenylsulfonyl)hydrazone)methyl)phenylfuran-2-carboxylate (17) and (E)-4-((2-((4-bromophenyl)sulfonyl)hydrazone)methyl)-2-methoxyphenylfuran-2-carboxylate (25) showed good antioxidant activity. Upon examining the acetylcholinesterase inhibitory activity, it was determined that compounds (E)-2-methoxy-4-((2-((4-methoxyphenyl)sulfonyl) hydrazone)methyl)phenylacetate (27) (10.39 μM), (E)-4-((2-((4-chloro phenyl)sulfonyl) hydrazone)methyl)-2-methoxyphenylfuran-2-carboxylate (21) (10.81 μM), (E)-4-((2-((4-chloro phenyl)sulfonyl)hydrazone)methyl)-2-methoxyphenyl thiophene-2-carboxylate (22) (12.92 μM) and (E)-2-methoxy-4-((2-(phenylsulfonyl)hydrazone)methyl)phenylfuran-2-carboxylate (17) (12.93 μM) showed potent inhibitory effects. Molecular docking simulations were used to investigate the interactions of novel sulfonyl hydrazone derivatives with human acetylcholinesterase protein. The ligands exhibited strong binding to the receptor protein with potent inhibition.

Propolis is a multi-functional bee product rich in polyphenols. In this study, the inhibitory effect of Anatolian propolis against SARS-coronavirus-2 (SARS-CoV-2) was investigated in vitro and in silico. Raw and commercial propolis samples were used, and both samples were found to be rich in caffeic acid, p-coumaric acid, ferulic acid, t-cinnamic acid, hesperetin, chrysin, pinocembrin, and caffeic acid phenethyl ester (CAPE) at HPLC-UV analysis. Ethanolic propolis extracts (EPE) were used in the ELISA screening test against the spike S1 protein (SARS-CoV-2): ACE-2 interaction for in vitro study. The binding energy values of these polyphenols to the SARS-CoV-2 spike and ACE-2 protein were calculated separately with a molecular docking study using the AutoDock 4.2.6 program. In addition, the pharmacokinetics and drug-likeness properties of these eight polyphenols were calculated according to the SwissADME tool. The binding energy value of pinocembrin was highest in both receptors, followed by chrysin, CAPE, and hesperetin. Based on the in silico modeling and ADME (absorption, distribution, metabolism, and excretion) behaviors of the eight polyphenols, the compounds exhibited the potential ability to act effectively as novel drugs. The findings of both studies showed that propolis has a high inhibitory potential against the Covid-19 virus. However, further studies are now needed.
