Abstract

Dengue virus (DENV) is one of the most common viral infections found Indonesia and tropical regions, and no specific antiviral for DENV. Indonesia has several of herbal medicine that were not explored of their potency as antiviral DENV. This study was done to evaluate the activity and toxicity of 4 derived fractions: Hexane (CA1), ethyl acetate (CA2), buthanol (CA3 ) and water (CA4) of Cassia alata leaf extract (CA) as an antiviral drug to DENV. The DENV was treated with various concentration of extract and added to Huh-7 it-1. The decrease of virus titer was determined by Focus assay. The toxicity of extract was measured by MTT assay. In our previous study, we found that CA on Huh-7 cells showed IC 50 , CC 50 and SI values of <10 μg/mL, 323.45 μg/mL, and more than 32.3, respectively. For the fractions, CA3 showed best antiviral activity among other, with IC 50 , CC 50 and SI of <10 μg/mL, 645.8 μg/mL, and more than 64.5, respectively. CA and CA3 were proven to possess antiviral activity that is potent when tested against DENV-2. Future study was needed to explore the inhibition mechanism and compound of CA that have potency as antiviral drug to DENV.
