Exploration of Moringa Oleifera and Curcuma Longa Compounds as Multi-Target Agents for Alzheimer’s Disease Through Bioinformatics Analysis

Background: Alzheimer’s disease is a multifactorial neurodegenerative disorder. Current synthetic inhibitors often fail to address its complexity. Natural multitarget agents like Moringa oleifera and Curcuma longa may offer safer alternatives. Objective: This study aims to systematically evaluate the bioactive compounds of Moringa oleifera and Curcuma longa as potential multi-target agents against AD using molecular docking, ADME profiling, and toxicity prediction. Methods: This in silico study targeted five Alzheimer-related proteins (BACE1, GSK-3β, AChE, Tau, PKR) retrieved from the PDB and prepared using AutoDock Tools. LC-MS compounds were modeled with Biovia Discovery Studio and docked via PyRx. Toxicity was evaluated using ProTox-3.0. Results: The top 10 compounds showed binding affinities from –7.3 to –10.2 kcal/mol and were “inactive” for hepatotoxicity, neurotoxicity, and cytotoxicity. Turmeric compounds were also non-mutagenic and non-carcinogenic. Conclusion: Moringa oleifera and Curcuma longa demonstrate promising multitarget activity with a favorable safety profile. Bioinformatics enables efficient early screening. Keyword: Alzheimer’s disease, Curcuma longa, Moringa oleifera, multitarget, molecular docking. Latar Belakang: Alzheimer merupakan gangguan neurodegeneratif multifaktorial. Inhibitor sintetik saat ini dinilai belum mampu mengatasi kompleksitasnya. Senyawa multitarget alami seperti Moringa oleifera dan Curcuma longa berpotensi lebih aman. Tujuan: Penelitian ini bertujuan untuk mengevaluasi secara sistematis senyawa bioaktif Moringa oleifera dan Curcuma longa sebagai agen multi-target potensial terhadap AD menggunakan docking molekuler, profil ADME, dan prediksi toksisitas. Metode: Studi in silico ini menargetkan lima protein Alzheimer (BACE1, GSK-3β, AChE, Tau, PKR) dari PDB yang diproses di AutoDock Tools. Senyawa LC-MS dimodelkan di Biovia Studio dan didocking menggunakan PyRx. Toksisitas dievaluasi via ProTox-3.0. Hasil: Sepuluh senyawa teratas menunjukkan afinitas –7,3 s.d. –10,2 kcal/mol dan “inactive” terhadap hepatotoksisitas, neurotoksisitas, serta sitotoksisitas. Senyawa kunyit juga tidak mutagenik dan tidak karsinogenik. Kesimpulan: Moringa oleifera dan Curcuma longa berpotensi sebagai terapi multitarget Alzheimer yang aman.
