At the end of 2019, the world faced a big challenge and crisis caused by the SARS-CoV-2 virus. It spreads rapidly and is contagious; no treatment has officially been found. Algeria has used medicinal plants native to the country to defend against this pandemic. The objective of this paper is based on a molecular docking study of the active compounds of five Algerian medicinal plants with their target Sars-2Cov-2 virus protease to assess their potential antiviral activity against COVID-19. Innovative software and computerized databases were introduced into the in-silico domain, mainly the Auto-Dock software version 1.5.6. Similar results were obtained for all ligands, with a better chemical affinity of − 5.600 kcal/mol for the protease target 6LU7 and − 5.700 kcal/mol for the protease target 6WTT, with an average of − 4.227 kcal/mol and − 4.221 kcal/mol, respectively. The protease targets 6LU7 and 6WTT. In the ADME-Tox study, the active compounds of Algerian medicinal plants also demonstrated an excellent pharmacokinetic and toxic profile. Best scores were noted for cedrol, camphor, and eucalyptol. A molecular dynamics simulation showed the stability of camphor-6LU7 and cedrol-6LU7 complexes, favoring the biological potential of white artemisia and cypress plants. Graphical Abstract

In this paper, a new series of some [3,5-di(4',5'-diphenyl-2'substituted)-1H-imidazol-1-yl)]-1H-1,2,4-triazole derivatives (C1-C9) were efficiently synthesized by a one-pot three component reaction via a coupling of benzil, aldehydes and 3,5-diamino-1,2,4-triazole and using ceric ammonium nitrate as a catalyst. The structures of the newly compounds were investigated by IR, 1 H NMR, 13 C NMR and UV-visible spectroscopy. The in vitro antibacterial and antifungal activities showed that the C9 is the most active compound. The C9 docking study revealed the best mode of binding in the active site of the cytochrome P450 lanosterol 14α-demethylase. All the synthesized compounds were predicted as non-carcinogens and demonstrated acceptable pharmacokinetic profile in blood brain barrier (BBB) and human intestinal absorption (HIA).A series of some [3,5-di(4',5'-diphenyl-2'-substituted)-1H-imidazol-1-yl)]-1H-1,2,4-triazole derivatives (C1-C9, Table 1) were obtained by condensation of benzil, corresponding aldehydes and 3,5-diamino-1,2,4-triazole, the rationality of the design and the synthesis of the newly compounds are shown in Scheme 1.
