AB  - Finding an effective drug to prevent or treat COVID-19 is of utmost importance in tcurrentpandemic. Since developing a new treatment takes a significant amount of time, drug repurposingcan be an effective option for achieving a rapid response. This study used a combined in silico virtualscreening protocol for candidate SARS-CoV-2 PLpro inhibitors. The Drugbank database was searchedfirst, using the Informational Spectrum Method for Small Molecules, followed by molecular docking.Gramicidin D was selected as a peptide drug, showing the best in silico interaction profile with PLpro.After the expression and purification of PLpro, gramicidin D was screened for protease inhibitionin vitro and was found to be active against PLpro. The current study’s findings are significantbecause it is critical to identify COVID-19 therapies that are efficient, affordable, and have a favorablesafety profile.

AB  - The UV-B represents the minor fraction of the solar spectrum, while UV-C is not contained in natural solar radiation, but both radiation types can cause damaging effects in plants. Cell walls (CWs) are one of the targets for external stressors. Juvenile P. omorika trees were treated either with 21 day-high doses UV-B or with 7 day- UV-C in open-top chambers. Using spectroscopic and biochemical techniques, it was shown that the response to UV radiation includes numerous modifications in needle CW structure: relative content of xylan, xyloglucan, lignin and cellulose decreased; cellulose crystallinity changed; yield of lignin monomers with stronger connection of C[dbnd]C in side chain with the ring increased; re-distribution of inter- and intra-polymer H-bonds occurred. The recovery was mediated by an increase in the activities and changes in isoform profiles of CW bound covalent peroxidases (POD) and polyphenol oxidases (PO) (UV–B), and ionic POD and covalent PO (UV–C). A connection between activities of specific POD/PO isoforms and phenolic species (m- and p-coumaric acid, pinoresinol and cinnamic acid derivatives) was demonstrated, and supported by changes in the sRNA profile. In vivo fluorometry showed phenolics accumulation in needle epidermal CWs. These results imply transversal connections between polymers and changed mechanical properties of needle CW as a response to UV. The CW alterations enabled maintenance of physiological functions, as indicated by the preserved chlorophyll content and/or organization. The current study provides evidence that in conifers, needle CW response to both UV-B and UV-C includes biochemical modifications and structural remodeling. © 2021 Elsevier Masson SAS
