Objective: This study is aimed to evaluate the anti-diabetic effect of sequentially extracted (hexane, dichloromethane, ethyl acetate, and ethanol) Myristica fragrans houtt (mace) through in vitro and in silico studies. Methods: The in vitro anti-diabetic effect of the sequentially extracted plant were evaluated for its alpha-amylase inhibitory activity and the potential binding was studied by in silico studies using Schrödinger Maestro.Results: All extracts showed dose dependent alpha-amylase inhibitory effect. At concentration 500 µg/ml, all the extracts showed more than 60% inhibition of the alpha-amylase enzyme and the highest inhibition (81.30%) at 500 µg/ml was observed in DCM extract of mace. Potential compounds were identified by in silico molecular docking studies of alpha-amylase with phytocomponents from DCM extract. Among the top three compounds from virtual screening, induced fit docking studies revealed 2,5-bis(3,4-dimethoxyphenyl)-3,4-dimethyloxolane possessed better binding affinity when compared with the drug metformin. Conclusion: The obtained in vitro and in silico results suggest that all extracts of Myristica fragrans can be used successfully for the management of diabetes mellitus.Keywords: Myristica fragrans, Mace, Sequential extraction, Alpha-amylase, Molecular docking.

Abstract Background In the wake of emergence of antimicrobial resistance, bioactive phytochemical compounds are proving to be important therapeutic agents. The present study envisaged in silico molecular docking as well as in vitro antimicrobial efficacy screening of identified phytochemical ligands to the dispersin (aap) and outer membrane osmoporin (OmpC) domains of enteroaggregative Escherichia coli (EAEC) and non-typhoidal Salmonella spp. (NTS), respectively. Materials and methods The evaluation of drug-likeness, molecular properties, and bioactivity of the identified phytocompounds (thymol, carvacrol, and cinnamaldehyde) was carried out using Swiss ADME, while Protox-II and StopTox servers were used to identify its toxicity. The in silico molecular docking of the phytochemical ligands with the protein motifs of dispersin (PDB ID: 2jvu) and outer membrane osmoporin (PDB ID: 3uu2) were carried out using AutoDock v.4.20. Further, the antimicrobial efficacy of these compounds against multi-drug resistant EAEC and NTS strains was determined by estimating the minimum inhibitory concentrations and minimum bactericidal concentrations. Subsequently, these phytochemicals were subjected to their safety (sheep and human erythrocytic haemolysis) as well as stability (cationic salts, and pH) assays. Results All the three identified phytochemicals ligands were found to be zero violators of Lipinski’s rule of five and exhibited drug-likeness. The compounds tested were categorized as toxicity class-4 by Protox-II and were found to be non- cardiotoxic by StopTox. The docking studies employing 3D model of dispersin and ompC motifs with the identified phytochemical ligands exhibited good binding affinity. The identified phytochemical compounds were observed to be comparatively stable at different conditions (cationic salts, and pH); however, a concentration-dependent increase in the haemolytic assay was observed against sheep as well as human erythrocytes. Conclusions In silico molecular docking studies provided useful insights to understand the interaction of phytochemical ligands with protein motifs of pathogen and should be used routinely before the wet screening of any phytochemicals for their antibacterial, stability, and safety aspects.

Background: Essential oils have been used for centuries. EOs are gaining increasing interest because of their acceptance by consumers and their safe status. For the first time, the effect of essential oils on the inhibition of lipases has been investigated in this work. Objective: We aimed in this study to investigate in vitro the inhibitory effects of the three essential oils of most used spices: Peppermint (Mentha piperita L.), cinnamon (Cinnamomum zeylanicum L.) and Cloves (Syzygium aromaticum L. Merr. et Perry) against Candida rugose lipase. In silico studies using molecular docking have been achieved to study the inhibition mechanism of major compounds of EO: menthol, carvacrol, eugenol and cinnamylaldehyde toward CRL. Methods: The inhibitory effect of three essential oils were determined by candida rugosa enzyme and pNP-L as substrate using spectrophotometry. Autodock vina was used for molecular docking with 50 runs. Results: We have found that these essential oils have a strong inhibitory effect with IC50 values 1.09, 1.78 and 1.13 mg/ml compared with Orlistat 0.06 mg/ml. The results show competitive inhibition for the three major compounds Menthol, Carvacrol and Eugenol with uncompetitive inhibition for Cinnamaldehyde. Different repetition ratios of hydrogen bonds and hydrophobic interactions were observed. The saved interactions were with His449, Ser209, Gly123, Gly124 and Phe344 for all molecules. Conclusion: These observations support using and considering essential oils and their major compounds as good sources for design new drugs to treat candidiasis and other diseases related to Lipases.

This study aimed to isolate xanthones from Garcinia forbesii and evaluated their activity in vitro and in silico. The isolated compounds were evaluated for their antioxidant activity by DPPH, ABTS and FRAP methods. The antidiabetic activity was performed against α-glucosidase and α-amylase enzymes. The antiplasmodial activity was evaluated using Plasmodium falciparum strain 3D7 sensitive to chloroquine. Molecular docking analysis on the human lysosomal acid-alpha-glucosidase enzyme (5NN8) and P. falciparum lactate dehydrogenase enzyme (1CET) and prediction of ADMET for the active compound, were also studied. For the first time, lichexanthone (1), subelliptenone H (2), 12b-hydroxy-des-D-garcigerrin A (3), garciniaxanthone B (4) and garcigerin A (5) were isolated from the CH2Cl2 extract of the stem bark of G. forbesii. Four xanthones (Compounds 2–5) showed strong antioxidant activity. In vitro α-glucosidase test showed that Compounds 2 and 5 were more active than the others, while Compound 4 was the strongest against α-amylase enzymes. In vitro antiplasmodial evaluation revealed that Compounds 2 and 3 showed inhibitory activity on P. falciparum. Molecular docking studies confirmed in vitro activity. ADMET predictions suggested that Compounds 1–5 were potential candidates for oral drugs. The isolated 2–5 can be used as promising phytotherapy in antidiabetic and antiplasmodial treatment.

The focus of this roadmap is to evaluate the possible efficacy of Artemisia herba-alba Asso. (Asteraceae) for the treatment of COVID-19 and some of its symptoms and several comorbidities using a combination of in silico (molecular docking) studies, reported ethnic uses, and pharmacological activity studies of this plant. In this exploratory study, we show that various phytochemicals from Artemisia herba-alba can be useful against COVID-19 (in silico studies) and for its associated comorbidities. COVID-19 is a new disease, so reports of any therapeutic treatments against it (traditional or conventional) are scanty. On the other hand, we demonstrate, using Artemisia herba-alba as an example, that through a proper search and identification of medicinal plant(s) and their phytochemicals identification using secondary data (published reports) on the plant’s ethnic uses, phytochemical constituents, and pharmacological activities against COVID-19 comorbidities and symptoms coupled with the use of primary data obtained from in silico (molecular docking and molecular dynamics) studies on the binding of the selected plant’s phytochemicals (such as: rutin, 4,5-di-O-caffeoylquinic acid, and schaftoside) with various vital components of SARS-CoV-2, it may be possible to rapidly identify plants that are suitable for further research regarding therapeutic use against COVID-19 and its associated symptoms and comorbidities.
