Abstract

Background: Antimalarial screening against nine species of the genus Cassia showed that the methanol extract of leaves Cassia spectabilis have the highest activity. Since it will be used as a traditional medicine, hence it is needed further studies of antimalarial activity of these plants by choosing a safer solvent, namely ethanol. Objective: In vitro anti-malarial activity against Plasmodium falciparum was conducted using the method of Trager and Jensen. Methods: The serial solution tested were: 100, 10, 1,  0.1 and 0.01 µg/ mL, while the in vivo test was performed based on Peter's test (The days suppressive test) that using P. berghei (strain ANKA) infected mice. Results: The results showed that ethanolic extract of C. spectabilis leaves has inhibitory activity against P. falciparum with IC50 value of 12.52 µg/ mL and against P. berghei with ED50 value of 131.5 mg/kg body weight. Conclusions: A further study to see the potential of ethanol extract from C. Spectabilis leaves as anti-malaria is warranted.

Abstract

Background: Hepatitis C Virus infection is a serious health problem that leads to chronic liver disease, liver cirrhosis, hepatocellular carcinoma, which causes high morbidity. Direct-Acting Antiviral Agents have been used as anti-hepatitis C Virus therapy. However, it was covered only in limited patients due to the high cost. Moreover, serious side effects and resistance cases were also reported in some HCV genotypes. Objective: This research aimed to find new anti-HCV from some Indonesia plants collected from Balikpapan Botanical Garden, East Borneo. Methods: Twenty-one leaf and stem barks extracts were successively extracted in n-hexane, dichloromethane, and methanol. Extracts were screened for their anti-HCV activity under in vitro culture cells in the concentration of 30 µg/mL. Plant extracts were inoculated in the Human Hepatocellular 7it and infected with HCV Japanese Fulminant Hepatitis strain 1a. Determination of 50% Inhibitory Concentration (IC50) value was further conducted at concentration of 100; 30; 10; 1; 0.1; 0.01 µg/ml of extracts. Results: In vitro anti-HCV activity revealed that among 21 plants extract, 11 extracts, namely, n-hexane extract from Luvunga scandens leaves, DCM extract from the leaf of L. scandens, Artocarpus sericicarpus, Artocarpus dadah, Eusideroxylon zwageri, Neolitsea cassiaefolia, methanol extract from A. sericicarpus and A. anisophyllus leaves, DCM extract from A. anisophyllus and A. elmeri stem bark, methanol extract from A. dadah stem bark, having potential inhibition with IC50 range 0.08 ± 0.05 to 12.01 ± 0.95 µg/mL. Conclusions: These results indicate that the eleven extracts could be good candidates as sources of anti-HCV agents.

Abstract

Background: Hepatitis c virus infection is a global health problem which chronically infected 71 million people in the world. This infection has a risk of becoming liver cirrhosis and hepatocellular carcinoma. Since the current HCV therapy has been developed by direct-acting antivirals (DAA), however, most patients get limited access due to the high cost. Therefore, further development anti-HCV agent still greatly needed. Ruta angustifolia is a natural resource which was reported to possess anti-HCV activity. Ribavirin is an antiviral agent used to treat several virus infections, either DNA or RNA. Ribavirin was known to inhibit HCV infection by regulated immune system in host cells and interfering the replication of HCV by inhibit HCV RdRp. Objective: The current study evaluated the combination treatment of R. angustifolia extracts and ribavirin by in vitro culture cells of Huh 7it. Method: The study was conducted under an invitro cell culture of Huh 7it and infected with JFH1a. Result:  The result demonstrated an enhancement effect of the extract by increasing the anti-HCV activity 3.5-fold higher compared to ribavirin alone. The 50% inhibitory concentration of ribavirin by single treatment was 10.43 ± 0.18 µg/mL, while in combination with Ruta angustifolia extract was 2.80 ± 0.03 µg/mL. Further analysis of the combination by CompuSyn software mediated a synergistic effect among the combination with a combination index value of 0.691. Conclusion: These results suggested that combination of Ribavirin and Ruta angustifolia should be considered in developing anti-hepatitis C virus agents.
