[Infeksi dengue (DENV) merupakan salah satu masalah global yang masih dialamihingga saat ini. Diperkirakan 50 hingga 100 juta orang di dunia positif mengalamiinfeksi dengue.Hingga saat ini, tatalaksana infeksi dengue hanyalah berupa terapisuportif dan belum ditemukan pengobatan dan vaksin dengue. SwieteniaMahagoni sudah dikenal dan digunakan sejak dahulu sebagai tanaman obat.Kandungan flavonoid pada tanaman ini diperkirakan memiliki efek antiviral.Untuk itu penelitian ini dilakukan untuk melihat potensi antiviral terhadap DENVdari ekstrak S. Mahagoni. Pada penelitian ini digunakan beberapa konsentrasiyakni 640 μg/mL, 320 μg/mL, 160 μg/mL, 80 μg/mL, 40 μg/mL, 20 μg/mL, 10μg/mL dan kontrol negatif adalah DMSO. Untuk menentukan hambataninfektivitas dapat digunakan metode Focus Assay sehingga dapat diperoleh nilaiInhibitory Concentration (IC50). Selain itu, untuk dilihat viabilitas sel denganmetode MTT assay sehingga diperoleh nilai Cytotoxic Concentration (CC50).Selain itu ditentukan juga nilai indeks selektivitas yang diperoleh dariperbandingan CC50 dan IC50. Berdasarkan hasil IC50, CC50 dan SI yakni 68,97μg/mL, 434,46 μg/mL dan 6,29, dapat dikatakan bahwa S. Mahagoni memilikiefek antiviral sehingga dapat digunakan sebagai antiviral dengue dimasamendatang.;Dengue infection (DENV) still becomes as global burden. It is estimated 50 to100 million people are positively infected by DENV. The recent management ofthis disease has not been found yet, with the lack finding of medicine and vaccine,the main management takes on supportive care. Swietenia mahagoni has beenused as the herbal medicine since long time ago. The flavonoid extract on thatplant is believed to have antiviral effect. This experiment was conducted toevaluate the antiviral DENV potential of S. mahagoni extract. In this experiment,the concentration was made on various concentration, from 640 μg/ml, 320μg/mL, 160 μg/mL, 80 μg/mL, 40 μg/mL, 20 μg/mL, 10 μg/mL, and DMSO asnegative control. Focus assay was used to determine the infectivity inhibitionwhich results of IC50 (inhibitory concentration), and MTT Assay was used todetermine the cell viability which results of CC50 (cytotoxic concentration).Selectivity index was also resulted by divided the value of CC50 with IC50. Theresults of IC50, CC50, and SI of S. mahagoni was 68,97 μg/mL, 433,46 μg/ml, and6,29 μg/ml respectively, S. Mahagoni has antiviral effect and could be consider tobe used as antiviral to DENV in the future, Dengue infection (DENV) still becomes as global burden.
