Active components in medicinal plants provide unlimited useful and traditional medicines. Antimicrobial activities are found in secondary metabolites in plant extracts such as argan oil. This experimental investigation aims to determine argan oil's volatile compounds and examine their in vitro antimicrobial properties. In silico simulations, molecular docking, pharmacokinetics, and drug-likeness prediction revealed the processes underlying the in vitro biological possessions. Gas chromatography-mass spectrometry (GC/MS) was used to screen argan oil's primary components. In silico molecular docking studies were used to investigate the ability of the selected bioactive constituents of argan oil to act effectively against Pseudomonas aeruginosa and Staphylococcus aureus ( S. aureus ) isolated from infections. The goal was to study their ability to interact with both bacteria's essential therapeutic target protein. The 21 chemicals in argan oil were identified by GC/MS. Docking results for all compounds with S. aureus and P. aeruginosa protease proteins ranged from -5 to -9.4 kcal/mol and -5.7 to -9.7 kcal/mol, respectively, compared to reference ligands. Our docking result indicates that the 10-octadecenoic acid, methyl ester was the most significant compound with affinity scores of -9.4 and -9.7 kcal/mol for S. aureus and P. aeruginosa proteins, respectively. The minimal bactericidal concentration (MBC) and minimal inhibitory concentration (MIC) of argan oil were 0.7 ± 0.03 and 0.5 ± 0.01 for S. aureus and 0.4 ± 0.01 and 0.3 ± 0.02 for P. aeruginosa , respectively. We confirmed the antimicrobial properties of argan oil that showed significant growth inhibition for S. aureus and P. aeruginosa., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Biosurfactants are surface-active molecules with unique qualities and various uses. Many microorganisms produce secondary metabolites with surface-active characteristics that serve various antiviral functions. The HIV and Zika viruses were chosen for this study because they can spread from mother to child and result in potentially fatal infections in infants. Halophilic bacteria from the Red Sea solar saltern in Egypt were screened using drop collapse, emulsification activity, and oil displacement assays to produce biosurfactants and emulsifiers. Halobacterium jilantaiense strain JBS1 was the most effective strain of the Halobacteriaceae family. It had the best oil displacement test and emulsification activity against kerosene and crude oil, respectively. Among the ten isolates, it produced the most promising biosurfactant, also recognized by the GC-MASS library. This study evaluated biosurfactants from halophilic bacteria as potential antiviral drugs. Some of the computer methods we use are molecular docking, ADMET, and molecular dynamics. We use model organisms like the HIV reverse transcriptase (PDB: 5VZ6) and the Zika virus RNA-dependent RNA polymerase (ZV-RdRP). Molecular docking and molecular dynamics make the best complexes with 5VZ6 HIV-RT and flavone (C25) and 5wz3 ZV-RdRP and ethyl cholate (C8). Testing for ADMET toxicity on the complex revealed that it is the safest medicine conceivable. The 5VZ6-C25 and 5wz3-C8 complexes also followed the Lipinski rule. They made five hydrogen bond donors and ten hydrogen bond acceptors with 500 Da MW and a 5:1 octanol/water partition coefficient. Finally, extreme settings require particular adaptations for stability, and extremophile biosurfactants may be more stable., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Almuhayawi, Elshafey, Hagagy, Selim, Al Jaouni, Sofy, Samy, Gattan, Alruhaili, Alharbi, Nagshabandi, Tarabulsi and Elnosary.)
