Abstract

Photoaging, a result of excessive UV exposure, increases ROS production and collagen degradation by MMPs, causing skin wrinkles and roughness. This study explores the potential of vitexin and orientin as natural antiphotoaging agents through in-silico molecular docking, comparing their efficacy against retinol in inhibiting MMP-1, MMP-3, and MMP-9 enzymes involved in photoaging. The research utilized Hyperchem 8 for compound optimization, Chimera 1.11 for target protein preparation, and AutodockTools 1.5.6 for docking analysis. Results demonstrated that vitexin and orientin exhibit stronger affinity towards MMP-1, MMP-3, and MMP-9, indicated by more negative binding energies than retinol. Their interaction with the MMP enzymes, characterized by specific hydrogen bonds with key amino acid residues, suggests a potent inhibitory effect. This affinity indicates vitexin and orientin’s potential as effective antiphotoaging agents, providing a basis for further exploration in skin care applications.

Abstract

Excessive melanin synthesis, often triggered by overexposure to UV rays, is catalyzed by melanogenesis enzymes such as tyrosinase, tyrosinase-related protein 1, and D-dopachrome tautomerase. Derived from natural sources, the flavonoid compound luteolin is explored for its antihyperpigmentation potential. This study assesses luteolin’s efficacy as an antihyperpigmentation agent by analyzing its affinity and bond interactions with melanogenesis enzymes through an in silico approach. Molecular docking, facilitated by HyperChem 8 for test compound optimization and Chimera 1.11.1 for protein preparation, alongside method validation and docking with AutoDockTools 1.5.6, established the protocol’s validity with an RMSD value of ≤3 Å. Docking results reveal luteolin's higher affinity for the target proteins compared to native ligands, with binding energies of -5.63 kcal/mol for tyrosinase, -6.18 kcal/mol for tyrosinase-related protein 1, and -6.54 kcal/mol for D-dopachrome tautomerase. The interaction between luteolin and these proteins involves hydrogen, hydrophobic, electrostatic, and Van der Waals bonds, with amino acid residues His61, Lys129, Arg132 (tyrosinase); His192, His224, Val89 (tyrosinase-related protein 1); and Ile64, Asn73 (D-dopachrome tautomerase) participating in hydrogen bond formation. These findings suggest luteolin’s significant potential as an antihyperpigmentation agent by inhibiting melanogenesis enzymes.

Abstract

Background: An unhealthy lifestyle characterized by consuming foods with a high glycemic index can increase blood sugar levels significantly. Diabetes mellitus therapy using antidiabetic drugs in patients aims to help control blood sugar levels. Objective: This study aims to determine the affinity and interaction models of trans-anethole, fenchone, and estragole as test compounds against the target proteins pancreatic ?-amylase and dipeptidyl peptidase-4 (DPP-4) enzyme, as well as in silico toxicity prediction of the test compounds. Methods: This study used AutoDock 4.2 as a molecular docking method to evaluate the affinity and interaction models of the test compounds against the target proteins pancreatic ?-amylase (PDB ID: 2QV4) and DPP-4 (PDB ID: 3W2T) as a potential antidiabetic agent. In addition, the toxicity of these compounds was predicted using the Toxtree program with Cramer Rules, Benigni/Bossa, Verhaar Sceme, and Kroes TTC parameters. Results: The results showed that the test compounds had binding energies that showed their affinity to the target protein. The trans-anethole did not show any structural features indicating potential toxicity. Fenchone has the class III category for the Cramer Rules parameters, and estragole has a structural alert for genotoxic carcinogenicity based on the Benigni/Bossa Rulebase parameter. Conclusion: Trans-anethole, fenchone, and estragole have been observed to exhibit antidiabetic potential through their interactions with the pancreatic proteins ?-amylase and dipeptidyl peptidase-4 (DPP-4) enzyme, although their effectiveness is not as high as that of the native ligands. Additionally, further toxicity testing is required for the three compounds. Keywords: Trans-anethole, Fenchone, Estragole, Molecular Docking, Antidiabetic

Abstract

BACKGROUNDCarica papaya is traditionally used to treat malaria. The mechanism of action of the active constituents may be determined by molecular docking. This study therefore examined the in silico antimalarial activity of selected compounds from Carica papaya using Plasmodium falciparum dihydrofolate reductase thymidylate synthase (PfDHFR-TS) as target protein. METHODSAntimalarial activity screening of Carica papaya compounds was done in silico using AutoDock 4.2 software which was equipped with Autodock tools 1.5.6 for preparation. Five compounds contained in Carica papaya leaves, i.e. quercitrin, isoquercitrin, carpaine, caricaxanthin, and violaxanthin were successfully docked with the target protein. The molecular docking method is declared valid if the RMSD obtained is not more than 2 Å. In vitro evaluation of the test compounds as antimalarials was accomplished by determining their inhibitory activity against dihydrofolate reductase thymidylate synthase (PfDHFR-TS) which plays a role in the synthesis of nucleotides needed by Plasmodium falciparum. RESULTSValidation of Plasmodium falciparum DHFR-TS with PDB ID 1J3I showed an RMSD value of 1.58 Å. The docking results showed that quercitrin, isoquercitrin, carpaine, and caricaxanthin showed negative energy values similar to the native ligand. Therefore the four compounds have good affinity for the target protein, while violaxanthin shows a positive energy value, indicating no affinity for the target protein. CONCLUSIONBased on binding affinity values and molecular interactions, isoquercitrin and quercitrin have inhibitory activity against dihydrofolate reductase thymidylate synthase (PfDHFR-TS), such that they have potential as natural antimalarial candidates.

Abstract

Background: The rhizome of Zingiber officinale (ginger) is widely recognized for its pharmacological properties, particularly its antioxidant activity, which is largely attributed to phenolic compounds such as gingerol, shogaol, paradol, and zingerone. Efficient extraction of these compounds requires suitable techniques to maximize yield while maintaining compound stability. Objective: This review aims to evaluate extraction techniques for phenolic compounds from ginger rhizomes, comparing traditional and modern approaches, and to identify methods that produce the highest total phenolic content (TPC). Methods: A literature review was conducted on original research articles published between 2015 and 2025 that reported phenolic extraction from Z. officinale using maceration, soxhlet extraction, reflux, microwave-assisted extraction (MAE), or ultrasound-assisted extraction (UAE). Articles were retrieved from Google Scholar and ScienceDirect databases and assessed against defined inclusion and exclusion criteria. Results: Six eligible studies were included, revealing substantial methodological heterogeneity that complicates direct method comparisons. UAE with 50% ethanol produced the highest TPC (155.19 ± 2.81 mg GAE/g dry weight), followed by Soxhlet extraction (31.10 ± 0.28 mg GAE/g) and MAE (27.89 ± 1.99 mg GAE/g). Reflux and maceration yielded comparatively lower TPC values, with results influenced by solvent type, concentration, temperature, and extraction time. Conclusion: UAE with 50% ethanol is the most effective technique for extracting phenolic compounds from ginger, offering both high yield and compound stability. MAE, while producing lower yields, remains advantageous for its shorter extraction duration.
