      Abstract
      Inflamasi yang disebabkan oleh infeksi SARS-CoV-2 dapat memicu terjadinya badai sitokin sehingga penggunaan antiinflamasi melalui penghambatan siklooksigenase-2 dapat menurunkan tingkat keparahan Covid-19. Penelitian ini bertujuan menentukan senyawa aktif biji dan kulit kayu mahoni yang berpotensi menghambat siklooksigenase-2 sebagai antiinflamasi melalui metode penambatan molekuler. Penambatan molekuler dilakukan dengan menggunakan aplikasi YASARA Structure. Hasil penelitian menunjukkan terdapat dua ligan biji mahoni, yaitu katekin dan epikatekin, serta dua ligan kulit kayu mahoni, yaitu scopoletin dan �-sitostenone berpotensi menghambat siklooksigenase-2. Ligan katekin dan epikatekin merupakan senyawa aktif kulit kayu mahoni dapat menghambat siklooksigenase-2 melalui interaksi pada situs aktif dengan nilai energi bebas ikatan sebesar -7,938 kkal/mol dan konstanta disosiasi sebesar 1,518 �M yang lebih rendah dari ligan pembanding ibuprofen. Selain itu, kedua ligan juga berpotensi sebagai kandidat obat melalui analisis bioavailabilitas dan farmakokinetik. Simpulan penelitian ini adalah ligan katekin dan epikatekin merupakan ligan paling berpotensi dalam menghambat siklooksigenase-2 sebagai antiinflamasi.
       
      of Covid-19. This study aims to determine the active compounds of mahogany seeds and bark that have the potential to inhibit cyclooxygenase-2 as an anti-inflammatory through molecular docking method. Molecular docking method is done using YASARA Structure application. The results showed that there were 2 mahogany seed, namely catechin and epicatechin, and 2 mahogany bark ligands, namely scopoletin and � -sitostenone that had the potential to inhibit cyclooxygenase-2. Catechin and epicatechin which are the active compounds of mahogany bark inhibit cyclooxygenase-2 through interaction with the active site with a bond free energy value of -7.938 kcal/mol and a dissociation constant of 1.518 M which is lower than the comparative ligand ibuprofen. In addition, both ligands are also potential drug candidates through bioavailability and pharmacokinetic analysis. In conclusion, catechin and epicatechin are the most potent ligands in inhibiting cyclooxygenase-2 as an anti-inflammatory.
