Extracts and some of the Agaricus blazrei Murill isolates have potential anticancer. Ergosterol isolate from Amaouroderma rude can also inhibit the growth of MDA-MB-231 cancer cells through apoptotic pathways by increasing FOXO3 expression, while its potency against MCF-7 cells has not been reported. The purpose of this study was to isolate, determine the structure, determine the anticancer activity of MCF-7 cells, and the isolate mechanism by apoptosis from one of isolates the n-hexane A.blazei Murill extracts. This research method includes the isolation of compounds from A.blazei Murill extract by chromatography method guided using Bioactivity Guided Isolation. The structure elucidation of structure isolates used UV, NMR and MS spectroscopy. Anticancer activity test using the MTT cytotoxic test. Eludation of UV, NMR and MS structures showed a ergostrerol. The anticancer activity test showed IC50 values of 43.10 μg/ mL with the strong cytotoxic category. The mechanism of action is to increase apoptosis induction through inhibition of the cell cycle in the G2/ M phase. The conclusion of the isolated compound was ergosterol with an IC50 value of 43.10 μg / mL with an increased apoptosis induction mechanism through inhibition of the cell cycle in the G2/ M phase.

Introduction: Hepatitis C Virus (HCV) is a major health problem, which infects approximately 170 million people among worldwide population. Moreover, there is no vaccine available to prevent HCV infection and the current anti-HCV drugs have not covered all the various genotypes and subtypes. Meanwhile, medicinal plants have been widely used to treat a variety of infectious disease. Our previous study reported that ethanol extract of Melicope latifolia has been shown to exert anti-HCV activity towards a number of different virus genotypes with mainly inhibition mechanism at the entry step. Further separation was needed to purify and identify the active anti-HCV constituent using bioactivity-guided isolation method. Materials and Methods: In vitro Anti-HCV assay was performed using hepatocyte cell line (Huh7it) and HCV genotype 2a (JFH1). The purification of M. latifolia ethanol extract (B1F) was done by liquid-liquid fractionation, vacuum liquid chromatography (VLC), and high-performance liquid chromatography (HPLC). The active fraction was further identified by thin layer chromatography (TLC) and the major constituent was determined by nuclear magnetic resonance (NMR) spectra data analysis. Results: The fractionation of M. latifolia leaves ethanol extract resulted an alkaloid fraction (B1F D2H.3) containing a major constituent N-methylflindersine. This alkaloid fraction was active to reduce HCV JFH1 with an inhibition concentration (IC50) value of 6.21 {\textmu}g/mL, a cytotoxicity concentration (CC50) value of 82.64 {\textmu}g/mL, and a selectivity index value of 13.31. Conclusion: An alkaloid fraction of M. latifolia (B1F D2H.3) was known to have major compound named N-methylflindersine. This alkaloid fraction exhibited strong anti-HCV against JFH1 in vitro. The results indicated that this alkaloid fraction may a good candidate for anti-HCV agent.

Introduction: Artocarpus altilis leaves extract has previously been reported as a potential antimalarial drug. Inhibition concentration (IC50) against P. falciparum and effective dose values (ED50) against P. berghei have been reported at 1.32 μg/ml and 0.82 mg/kg, respectively. The aim of this study is to identify the active compound from the ethanol extract of A. Altilis leaves against P. falciparum. Materials and Methods: The isolation of the active compound from the ethanol extract of A. altilis were conducted using chromatography methods, and the chemical structure of the isolated compounds was determined based on NMR and MS spectra data. Antimalarial assay was determined using microscopic method against P. falciparum 3D7 and molecular docking studies was performed using Molegro Virtual Docker version 5.5 program. Results: A flavonoid compound, class of dihydrochalcone was finally isolated from A. altilis and identified as 1-(2,4-dihydroxy phenyl)-3-[8-hydroxy-2-methyl-2-(4-methyl-3- pentenyl)-2H-1-benzopyran-5-yl]-1-propanone (Compound-1). Antimalarial activity test revealed that the compound strongly inhibited P. falciparum growth, with IC50 value of 1.05 μM. An in silico study to determine the mechanism of action of the compound revealed the existence a 3.BPF receptor that possesses a cysteine protease inhibitor of falcipain-2. Conclusion: Compound-1 were isolated from the leaves of A. Altilis is a good candidate of new source in the development of antimalarial drugs. An animal study using this compound is recommended before a clinical trial.

Background: Hepatitis B virus (HBV) infects more than 300 million people globally and is a common cause of liver cancer. Current therapy using reverse transcriptase inhibitors require long-term treatment and the potential risk of development of drug-resistant viruses remains an important issue to be considered. Hence, the development of new drugs is critical. Traditional medicinal plants used for the treatment of infectious diseases may provide a viable option for the discovery of anti-HBV drug candidates. Objective: This study examined anti-HBV activity of 31 kinds of Indonesian plants. Materials and Methods: Crude extracts of various part of plants, leaves and stem, were obtained using dichloromethane and ethanol solvent. The effect on viral entry was examined by determining levels of HBsAg expression in the supernatants of HBV-infected HepG2-NTCP cells by ELISA. The effect on HBV replication was determined by measuring HBV DNAs amounts in Hep38.7-Tet cells by quantitative real-time PCR. Results: The extracts of Phyllantus niruri leaves and Curcuma xanthorrhiza showed reduction of strong HBsAg production from HepG2-NTCP cells with IC50 values of 170.48 and 270.51 μg/mL, respectively. Treatment of HepAD38.7-Tet cells with P. niruri and C. xanthorhiza at the highest concentration while avoiding cytotoxicity reduced extracellular HBV DNA levels by 70\% and 30 \% of the untreated control respectively. Conclusion: P. niruri inhibited both the entry and HBV replication, thus P. niruri is a promising candidate for anti-HBV drug development.

Background: Amoebiasis is caused by Entamoeba histolytica, which is a pathogenic species living on human colon tissues. The development of new drugs for anti-amebic are still very needed for clinical treatment. Objective: This aims to identify the compounds in Cratoxylum sumatranum for their anti-amoeba activity. Materials and Methods: In this study we used bioactivity-guided isolation and structural analysis to identified anti-amebic compounds from dichloromethane extract of Cratoxylum sumatranum stem bark. Their anti-amebic activity was determined by an in vitro cell-based assay against Entamoeba histolytica and an enzymatic assay on NAD kinase. Results: Two known compounds from the cage xanthone groups, namely cochinchinoxanthone (1) and cochinchinone D (2), were isolated. The structures of the cage xanthone compounds were established by extensive spectroscopic data analysis. Compound (1) showed the greatest level of anti-amebic activity both in cell-based and enzymatic assay, yielding IC50 values of 4.57 and 12.17 μg/mL, respectively. In contrast, compound (2) yielded IC50 values of 5.19 and 12.60 μg/mL, respectively. Conclusion: When considering the demonstrated anti-amebic activities, it becomes apparent that these compounds, isolated from Cratoxylum sumatranum stem bark, have the potential to be further developed into effective anti-amebic medicine against Entamoeba histolytica.
