The inhibition of violacein production in &lt;em&gt;Chromobacterium violaceum&lt;/em&gt; (ATCC 07) was assayed as anti-quorum sensing activity using micro-dilution method. The molecular docking of the GC-MS ligands and penicillin‑binding protein 2x (PDP2) and CviR was executed using AutoDock Vina. &lt;strong&gt;Results: &lt;/strong&gt;The two volatile compounds namely phytol (93.58%) and 3-tetradecyn-1-ol (6.42%) were shown by GC-MS. The extract exhibited antibacterial activity against the selected bacterial strains with minimum inhibitory concentration (MIC) values ranging from 1.56 to 3.125 mg/mL. The maximum inhibition of violacein production of 53.93% was observed at 1.56 mg/mL. Both compounds had docking scores of more than -6.0 kcal/mol against the target proteins. &lt;strong&gt;Conclusion: &lt;/strong&gt;The results revealed that the extract is a potential source of antibacterial and anti-quorum sensing compounds and thus can have pharmacological applicability.&lt;/p&gt;

Antibacterial activity of the extract was investigated against &lt;em&gt;Staphylococcus aureus &lt;/em&gt;(ATCC 25923), &lt;em&gt;Bacillus cereus&lt;/em&gt; (ATCC 10102), &lt;em&gt;Escherichia coli &lt;/em&gt;(ATCC 25922) and &lt;em&gt;Pseudomonas aeruginosa&lt;/em&gt; (ATCC 27853) using the broth dilution method. The standard 2.2-diphenyl-1-picrylhydrazyl (DPPH) and 2.2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods were used to evaluate the scavenging activities of the extract. Anti-quorum sensing activity was assessed against biosensor strain- &lt;em&gt;Chromobacterium violaceum &lt;/em&gt;(ATCC 12472). Cytotoxicity in HepG2 cells was investigated using the tetrazolium-based colorimetric (MTT) assay. &lt;strong&gt;Results: &lt;/strong&gt;The extract revealed eight volatile compounds with cis-Vaccenic acid (87.06%) and 9-Octadecenoic acid, 1,2,3-propanetriyl ester (5.21%) as the major components. Antibacterial activity against all tested strains with minimum inhibitory concentration range of 1.56 - 12.5 mg/mL was observed. The DPPH and ABTS assays demonstrated scavenging activities with the median inhibitory concentration (IC&lt;sub&gt;50&lt;/sub&gt;) values of 0.09 mg/mL and 0.003 mg/mL, respectively. The extract also displayed strong anti-quorum sensing activity with 93% inhibition of violacein production at 25 mg/mL. A half maximum inhibitory concentration (IC&lt;sub&gt;50&lt;/sub&gt;) of 5370 μg/mL was computed in HepG2 cells. &lt;strong&gt;Conclusion:&lt;/strong&gt; The extract has potential to be used as a source of therapeutic compounds in pharmaceutical applications.&lt;/p&gt;

Drug-likeness of the compounds was evaluated based on the Lipinski rule of five (Ro5).&lt;em&gt; In silico&lt;/em&gt; mutagenicity, carcinogenicity and inhibition of human ether-a-go-go-related (hERG) gene were also investigated using PreADMET web tool. &lt;strong&gt;Results: &lt;/strong&gt;The physicochemical properties showed the compounds, except 9-Octadecenoic acid, 1, 2, 3-propanetriyl ester to adhere to Ro5. The evaluation of their inhibitory effects profile in several cytochrome P450 isoforms indicate that all the compounds are not the inhibitors of CYP2C19 and CYP3A4 whereas some inhibited CYP1A2, CYP2C9 and CYP2D6. The drug-likeness evaluation employed Ro5 as a filter and all compounds complied with it except for 9-Octadecenoic acid, 1, 2, 3-propanetriyl ester. About 50% of the tested compound were found to be safe as they did not exhibit antimutagenic and carcinogenic effects. Moreover, the risk of inhibition of hERG gene revealed to be low to medium risk depending on the compound. &lt;strong&gt;Conclusion: &lt;/strong&gt;The calculated physicochemical and pharmacokinetic properties suggest that most of the compounds are safe and have promising oral bioavailability.&lt;/p&gt;

Medicinal plants are known to possess phytocompounds with antibacterial activity and less toxic effects.&lt;strong&gt; Objective:&lt;/strong&gt; This study aimed at determining the chemical composition of the methanolic&lt;em&gt; Ricinus communis&lt;/em&gt;` leaf extract and evaluate their antibacterial and toxic effects. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;R. communis&lt;/em&gt; leaves were extracted by acetone, chloroform, ethanol and methanol. The extracts were assessed for antibacterial activity against &lt;em&gt;Bacillus cereus&lt;/em&gt; (ATCC 10102), &lt;em&gt;Escherichia coli &lt;/em&gt;(25922), &lt;em&gt;Staphylococcus aureus&lt;/em&gt; (25923) and &lt;em&gt;Pseudomonas aeruginosa&lt;/em&gt; (ATCC 27853) using agar-well diffusion and microwell dilution methods. The extracts were screened for alkaloids, flavonoids, saponins, steroids, tannins and terpenoids. The chemical constituents of the methanolic extract were analysed by gas chromatography – mass spectrophotometry (GC-MS). In silico toxicity of the phytocompounds were investigated using PreADMET tool. &lt;strong&gt;Results:&lt;/strong&gt; The methanol extract showed the antibacterial activity against the bacterial strains, with the MIC values of 1.56 mg/mL against &lt;em&gt;B. cereus&lt;/em&gt;, 3.13 mg/mL and 6.25 mg/mL against &lt;em&gt;P. aeruginosa&lt;/em&gt; and &lt;em&gt;E. coli&lt;/em&gt;. The extracts revealed the presence of alkaloids, flavonoids, glycosides, steroids, tannins, terpenoids and saponins. The GC-MS showed phytocompounds namely hexadecanoic acid, methyl ester (0.62%), tridecanoic acid (0.76%), pentafluoropropionic acid, nonyl ester (0.85%), 10-octadecanoic acid, methyl ester (2.93%) and cis-vaccenic acid (94.84%). Hexadecanoic acid, methyl ester was predicted not to have mutagenic and carcinogenic effects. Moreover, all compounds exhibited low inhibitory risks against hERG gene. &lt;strong&gt;Conclusion: &lt;/strong&gt;&lt;em&gt;R. communis &lt;/em&gt;leaf extract has potential to be used as a safe source of therapeutic compounds.&lt;/p&gt;
