Cellular senescence mainly contributes to aging through dysregulation of intracellular signaling pathways, including those controlled by PDK1. The inhibitors of PDK1 derived from Caulerpa lentillifera have not been widely investigated. This research aims to address the gap and PREDICTS novel compounds that can safely mitigate senescent-induced aging.
This study presents in silico methodology to evaluate bioactive compounds of sea grapes as candidate PDK1 inhibitors with potential anti-senescence activity. The reported bioactives were filtered for drug-likeness in DataWarrior. Machine learning utilizing KNIME-RDKit was trained across RF, MLP, and SVM models. Molecular docking was executed in MOE using rigid receptor protocol validated by redocking Staurosporine. Top-ranked compounds underwent ADMET prediction via pkCSM to evaluate their pharmacological and safety profiles.
Out of 275 compounds screened, 77.46% met Lipinski’s criteria, and the RF model filtered the dataset into 32.39?tive candidates across diverse phytochemical classes, including terpenoids, alkaloids, and peptides. Molecular docking targeting the ATP-binding pocket identified PubChem CID 10388222, 38361380, and 688827 as the superior candidates with the lowest docking score of -7.5167 kcal/mol. With constrained pharmacokinetic and safety profiles across the top three candidates, this study concludes that CID 10388222 as superior candidate that highly shows Type-I Kinase Inhibitor binding mode, but limited by its ADMET profile compared to other candidates.
