Abstract

Phenolic and flavonoid compounds have been found to have positive benefits due to their antioxidant activity. Alpinia purpurata (Viell.) K. Schum, or lengkuas merah, is known to have aromatic rhizomes and is rich in active compounds such as flavonoids and phenolics. This research aimed to investigate the total phenolic and flavonoid content of A. purpurata ethanol extract and its antioxidant activity. A. purpurata was extracted using Microwave-Assisted Extraction (MAE) with 97% ethanol solvent. The ethanol extract of A. purpurata was then analyzed for the total phenolic and flavonoid content. The antioxidant activity and nitric oxide (NO) levels were determined by DPPH and NO scavenging assay, respectively. The results showed that A. purpurata ethanol extract had a high phenolic content (148.76 ± 1.03 mg GAE.g-1extract) but weak DPPH scavenging activity (IC50 of 219.06 ± 8.15 µg.mL-1), indicating that high phenolic content does not necessarily correlate with strong antioxidant properties. In contrast, the extract exhibited strong NO scavenging activity with an IC50 of 22.73 ± 7.57 µg.mL-1. Despite its high phenolic content, the weak DPPH activity indicates that total phenolic concentration alone is not always a reliable indicator of antioxidant strength. Further studies should include additional antioxidant assays to comprehensively evaluate the extract’s antioxidant potential.

Abstract

Cancer is one of the leading causes of death in the world. Rosmarinic acid becomes one of the important polyphenolic compounds. It includes derivatives of two amino acids, caffeic acid from phenylalanine and 3,4-dihydroxyphenyl-lactic acid from tyrosine, secondary metabolites found in many herbal plants from the subfamily Lamiaceae and Boraginaceae. Rosmarinic acid works in inhibiting the occurrence of metastases and tumor formation. In this study, we evaluated rosmarinic acid and its derivatives through study literature. The compounds were downloaded from the PubChem database, while the three-dimensional structure of HIF-1a was retrieved from RCSB PDB. The biological activity was analyzed using the PASS server, and the cytotoxic effect was predicted using CLC-Pred., The pharmacological properties of bioactive compounds were analyzed using SwissADME. The compounds and HIF-1a were prepared using PyRx 0.8 version and Discovery Studio software, docked specifically using Autodock Vina, visualized using Discovery Studio software, and molecular dynamic simulation using CABS-flex 2.0. Rosmarinic acid and its derivative showed an inhibition with the highest affinity value of compound against HIF-1a are control (-6.9 kcal/mol), Rosmarinic acid (-6.4 kcal /mol), and Methyl rosmarinate (-6.3 kcal/mol). Rosmarinic acid could be expected to have activity as an inhibitor modulated at the post-translational level. Comprehensive and further analysis is required in future research based in vivo and in vitro for the development of cancer treatments.

Abstract

Breast cancer's increasing prevalence globally underscores the urgent need for effective and gentle therapies, positioning the exploration of herbal remedies as a critical pursuit. Daruju (Acanthus ilicifolius L.) emerges as a compelling candidate due to its inherent bioactive components. This research pioneers the application of advanced computational techniques to unveil the latent anti-breast cancer potential within A. ilicifolius. Our in-silico investigation commenced by cataloging A. ilicifolius compounds using the KNApSAcK database and existing literature. These compounds underwent rigorous screening for drug-like characteristics via SWISS-ADME and potential biological activity using PASS ONLINE. Protein targets relevant to breast cancer were predicted through SWISS Target and the STRING database, integrated with Cytoscape for network visualization. Molecular docking, performed with PyRx 0.8, assessed the binding strength between the identified compounds and target proteins, with the most promising interactions selected for further scrutiny. The stability of these crucial interactions was then evaluated through molecular dynamics simulations using YASARA. This comprehensive computational strategy aims to pinpoint potential anti-breast cancer agents derived from A. ilicifolius. Initial analysis of 17 compounds from A. ilicifolius, based on chromatography, databases, and prior studies, narrowed down to five that adhered to Lipinski’s Rule of Five for drug-likeness: 4-O-beta-D-glucosyl-4-coumaric acid, (-)-lyoniresinol, α-amyrin, adenosine, and p-coumaric acid. These compounds were predicted to directly interact with key breast cancer-related proteins across pathways like estrogen signaling, JAK/STAT, and PI3K/AKT. Notably, molecular docking revealed strong binding affinities for α-amyrin with CDK4, ER, and EGFR (-7.5 kcal/mol, -9.5 kcal/mol, and -8.7 kcal/mol, respectively), comparable to known inhibitors. Molecular dynamics simulations further corroborated the stability of these complexes, analyzing RMSD and binding affinity parameters. Consequently, α-amyrin stands out as a promising anti-breast cancer agent within A. ilicifolius, exhibiting potential to inhibit proteins crucial for breast cancer cell proliferation and survival, including CDK4, ER, and EGFR.
