Abstract

The immune response is divided into innate immune response and adaptive immune response. Macrophages are one of the immunity cells that work both in innate and adaptive immune response. The activities of secondary metabolites present in agarwood-producing plants allow the potential for natural immunomodulators so that the purpose of this study was to determine the potential G. versteegii extract leaves as immunomodulator and to examine the effect of G. versteegii leaves extract toward macrophage cells of mice (Mus musculus L.). The steps to be carried out in this study were the preparation of G. versteegii leaves extract with multi-level extraction, collection of M. musculus, cytotoxicity test with MTT assay, phagocytosis activity test of macrophages calculated by light microscopy (400X), and Griess assay for NO production of macrophages. The cytotoxicity test resulted an IC50 value of G. versteegii leaves extract was 183.45 µg/mL and the Imboost® as comparison solution is 20.12 µg/mL. This value used to determine the concentration of extract for phagocytosis activity test and NO production of macrophages test. The results showed that G. versteegii leaves extract has the potential as an immunomodulator and extract with 20 µg/mL concentration has the highest effect on phagocytosis activity and NO production.

Abstract

Women’s breast cancer incidence rate in Indonesia ranks number one with 12 per 100,000 cases, with luminal A as the dominant subtype. Currently, chemotherapeutic agents have limitations that lead to inefficiencies in therapy, therefore it is necessary to develop more effective and efficient chemopreventive agents. Plant secondary metabolites can provide pharmacological effects that can be used as chemoprevention agents. Secondary metabolites of D. serrata may have pharmacological effects as antioxidants and cytotoxic. This study aims to determine the antioxidant properties and cytotoxic activity of D. serrata ethanolic extract on the MCF-7 breast cancer cell line. The leaves of D. serrata were macerated, while the bark and root samples were refluxed with 96% ethanol as solvent. All extracts were evaporated with a rotary evaporator. Qualitative evaluation of the phytochemical content of leaf ethanolic extract, bark ethanolic extract, and root ethanolic extract was done using the standard tube test method. The antioxidant assay was carried out using the DPPH. The cytotoxic activity was determined in vitro using an MTT assay against the MCF-7 cell line with a series of concentrations from 12.5–400 μg/mL. Doxorubicin was the positive control treated at a 3.125–100 μg/mL concentration. The antioxidant activity showed that leaf extract had the highest antioxidant activity, followed by root and bark extract, with IC50 values of 95.66, 270.5, and 335.96 ppm, respectively. Leaf ethanolic extract and root ethanolic extract’s cytotoxic ability is considered moderate cytotoxic with IC50 values of 493.17 and 229.82 μg/mL, respectively. Amongst the ethanolic extract from the leaf, bark, and root of D. serrata, the leaf ethanolic extract has the best anti-oxidant activity and the bark ethanolic extract was the most cytotoxic one against MCF-7 cells.Keywords: Antioxidant, Cytotoxic, Dillenia serrata, MCF-7.

Abstract

Black rice is an alternative staple food better than white rice. It has lower carbs, but higher antocyanin compared to white rice. Nowadays, black rice consumption has increased, production needs to be increased to accomodate the demand. But, to our knowledge, there is lack of information about black rice resistance against biotic stresses, one of black rice cultivar is Cempo Ireng. This information needed for optimal Cempo Ireng cultivation. In this research, we determined chlorophyl content and analyzed OsNPR1 expression of three cultivars: Java14 (resistant control), Cempo Ireng, and IR64 (susceptible control), against Xanthomonas oryzae (Xoo). All of them were sprayed with salicylic acid (SA) before inoculated with Xoo. IR64 24h had the lowest chlorophyll content (0,576 ± 0,066 mg/g), meanwhile Java14 72h had the highest content (2,358 ± 1,301 mg/g). However, all the cultivars did not show any correlation between them and time after Xoo inoculation. OsNPR1 expression did not show any significant change in Java14 and Cempo Ireng after being inoculation. However, IR64 showed increasing OsNPR1 in 72h and did not change in 96h after inoculation. It indicated that OsNPR1 played important role in IR64 resistance against Xoo, but not in Cempo Ireng and Java14.
