In Silico Studies of Carotenoid Antioxidants in Sand Lobster (Panulirus homarus) as Candidate Anti-Breast Cancer Compounds
Main Article Content
Abstract
Breast cancer is the most diagnosed and deadliest type of cancer among women worldwide. In Indonesia, breast cancer ranks as the most prevalent and deadly cancers, with 58,256 cases and 22,692 deaths. This research aims to analyze the potential of carotenoid antioxidants found in the sand lobster (Panulirus homarus) as breast cancer treatment candidates through an in silico approach. In this study, six carotenoid compounds were evaluated: dinoxanthin, diadinoxanthin, zeaxanthin, lutein, astaxanthin, and violaxanthin, using 4-hydroxytamoxifen, genistein, and exemestane as standard ligands, and tamoxifen, metformin, and letrozole as positive controls. The 3D crystal protein structures used for molecular docking were obtained from the Protein Data Bank (PDB), including estrogen receptor alpha (PDB ID: 3ERT), estrogen receptor beta (PDB ID: 1X7J), and aromatase (PDB ID: 3S7S) as target receptors. Subsequently, bioactivity and bioavailability analyses of the test compounds were performed. Proteins and test compounds were prepared, followed by molecular docking against the estrogen receptor alpha, estrogen receptor beta, and aromatase, with visualization performed using Discovery Studio. Molecular dynamics simulations were performed to evaluate the stability of binding interactions. Toxicity prediction was carried out using the Protox Web Server (https://tox-new.charite.de/protox_II/). The in silico results indicate that two of the six tested compounds, lutein and violaxanthin, showed favorable predicted binding interactions with estrogen receptor alpha, estrogen receptor beta, and aromatase. Additionally, in silico toxicity predictions indicated favorable toxicity profiles for these compounds, suggesting their potential as candidates for further investigation against breast cancer.
