Introduction: Traumatic brain injury (TBI) is still a major health problem in the world. It might cause long-term disability that affect socio-economic life and become nation health burden. Post-traumatic cerebral edema might develop and commit to an unfavorable prognosis. Aquaporin 4 (AQP4) is water channel protein and a key regulator of water metabolism in the brain. Although the mechanism of AQP4 in the regulation of post-traumatic brain edema remains controversial, AQP4-lacking mice show better survival and decreased brain edema. Thus, novel strategies that suppress AQP4 become a potential field. We hypothesized that Kaempferia galanga L. may suppress brain expression of AQP4 following TBI and possibly limit the development of cerebral edema due to its neuroinflammation properties. Method: We conducted TBI to experimental rats, then given Kaempferia galanga L. extract at a dose of 600 mg/kg BW and 1200 mg/kg BW. Evaluation intensity of AQP4 expression by immunohistochemistry was performed 24 and 48 hours later to see its therapeutic effect. Results: Administration of Kaempferia galanga L. extract at a dose of 1200 mg/kg BW showed weak expression of AQP4 in all samples, both 24 and 48 hours following traumatic brain injury treatment. Conclusions: Intensity of AQP4 expression in rats{\textquoteright} brain was lower at 24 and 48 hours after TBI in rats receiving Kaempferia galanga L. extract with dose 1200 mg/ kg BW compared to the other groups. Our result indicates that Kaempferia galanga L. might affect the expression of brain AQP4 in a dose-dependent manner.

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.

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.
