Abstract

The occurrences of a highly pathogenic avian influenza virus (HPAI) type A H5N1 has caused infections in millions of poultry as well as hundreds of human cases and even mortalities. Indonesia has become one of the world’s highest casualty rates of H5N1 human infections, with the number of deaths was 167 from a total of 199 cases. The development of viral resistance towards the available anti-influenza drugs neuraminidase (NA) inhibitors required the discovery of new inhibitors. In the recent advance of drug discovery, natural products have been considered as one of the essential sources of medicinal agents, and Brucea javanica has been found to possess antiviral activity against H5N1 NA. Thus, this research aimed to investigate the in silico activities of compounds from B. javanica using molecular docking methods against H5N1 NA. In this study, docking-based virtual screening of compounds from B. javanica to quickly select in silico hits to be potential NA inhibitors was performed. Subsequently, the intermolecular interactions of the inhibitor compounds with the H5N1 NA were analysed to examine the most preferred interactions. The results showed that brucein G and bruceoside C were found having the lowest binding energy and most preferred interactions with H5N1 NA and therefore, can be proposed for further study as potential NA inhibitors.Keyword: antiviral, Brucea javanica, H5N1, molecular docking, neuraminidase

Abstract

Malaria is a disease that occurs in tropical countries like Indonesia. The incidence of malaria in the world is still quite high and the occurrence of cases of Plasmodium resistance to antimalarial drugs and the widespread of resistance have prompted researchers to look for new antimalarial drugs, especially from natural materials. Betel leaf (Piper betle Linn.) And sunflower leaf (Helianthus annuus L.) have long been used by the people of Indonesia as an antimalarial drug. The purpose of this study was to determine antimalarial activity through inhibition of heme polymerization and determine secondary metabolite compounds by phytochemical screening from betel leaves and sunflower leaves. The heme polymerization inhibition activity assay was carried out by the in-vitro method using a microplate reader at 415 nm and 630 nm wavelengths. IC50 values of betel leaf extract and sunflower leaf were 178.67 μg/ml and 160.10 μg/ml, respectively. Phytochemical screening results from betel leaf showed the presence of flavonoids, polyphenols, tannins, quinones, saponins, and monoterpenoids-sesquiterpenoids, while sunflower leaves contain alkaloids, polyphenols, flavonoids, steroids and monoterpenoids-sesquiterpenoids.Keywords: Piper betle Linn., Helianthus annuus L., Malaria, Heme Polymerization
