Abstract: Depresi merupakan gangguan suasana hati yang berhubungan dengan aktivitas enzim MAO-A. Senyawa aktif berupa flavonoid dari tanaman asam jawa diduga memiliki potensi antidepresan, tetapi interaksinya dengan MAO-A masih perlu divalidasi. Penelitian ini bertujuan mengevaluasi stabilitas interaksi lima senyawa aktif asam jawa yaitu apigenin, kaempferol, luteolin, morin, dan kuersetin— dengan enzim MAO-A melalui simulasi dinamika molekuler selama 200 ns menggunakan perangkat lunak Amber. Analisis dilakukan berdasarkan parameter RMSD, RMSF, radius girasi, ikatan hidrogen, total energi, jarak, dan MMGBSA. Hasilnya menunjukkan bahwa semua senyawa tetap berada dalam situs aktif sepanjang simulasi. Kompleks apigenin–MAO-A memiliki nilai MMGBSA paling negatif dan interaksi hidrogen dominan dengan residu Asn170 mengindikasikan afinitas dan kestabilan tinggi. Temuan ini menguatkan potensi apigenin sebagai kandidat inhibitor MAO-A berbasis fitofarmaka dan mendukung peran flavonoid asam jawa sebagai agen antidepresan alami.
Depression is a mood disorder associated with the activity of the MAO-A enzyme. Active compounds in the form of flavonoids from tamarind are suspected to have antidepressant potential, but their interaction with MAO-A need to be validated. This study aimed to evaluate the interaction stability of five T. indica-derived flavonoid compounds—apigenin, kaempferol, luteolin, morin, and quercetin—with MAO-A using molecular dynamics simulation for 200 ns using Amber software. The analysis was based on RMSD, RMSF, radius of gyration, hydrogen bonding, total energy, distance, and MMGBSA parameters. The results showed that all compounds remained within the active site throughout the simulation. The apigenin–MAO-A complex exhibited the most negative MMGBSA value and dominant hydrogen bonding with Asn170, indicating high affinity and stability. These findings support the potential of apigenin as a phyto-based MAO-A inhibitor and reinforce the role of tamarind flavonoids as natural antidepressant agents.
