Abstract

A new antiplasmodial compound, 2-(3H-diazirine-3-yl)benzaldehyde (1), has been isolated from the Papuan marine sponge Xestospongia sp. The structure elucidation of compound 1 was determined by spectroscopic evidences including UV, IR, MS, 1D and 2D-NMR analysis. Compound 1 showed moderate antiplasmodial activity against Plasmodium falciparum with IC50 value of 1.08 x 10-6 mM. DOI:http://dx.doi.org/10.15408/jkv.v4i1.6735

Abstract

Discovery of new antibacterial agent to treat oral disease caused by pathogenic oral bacteria is an attracted focus to more pay attention of researcher. The tropical natural product is the promising sources of new bioactive as antibacterial compounds. The epiphyte plant of Sarang Semut (M. pendans) empirically has been used as a drug to treat various diseases. Our previous research found that ethyl acetate extract of Sarang Semut inhibited the bacteria growth of Enterococcus faecalis. This study aims to isolate, structure determination and antibacterial activity evaluation of active compound against Streptococcus mutans ATCC 25175. The isolation by combination chromatography on normal and reverse phase resulted an antibacterial compound 1. Based on the analysis of the spectroscopic data including IR, FTIR, 1H-NMR, 13C-NMR, 2D-NMR as well as by mass spectroscopic (MS) and compare to reported data, structure of compound 1 was suggested as terpenoid type diterpene derivative. Antibacterial activity evaluation by Kirby-Bauer method of compound 1 against S. mutans ATCC 25175 showed inhibition zone values were 17.8, 14.5 and 11.1 mm at 10000, 5000 and 1000 ppm, respectively, while the MIC and MBC values were 18.125 ppm with MBC of 2500 ppm, respectively.

Abstract

Two flavonoid compounds, quercetin (1) and quercetin-3-O-glucoside (2) have been isolated from the bark of Sonneratia alba (Lythraceae). Chemical structure of both compounds were determined on the basis of spectroscopic data and comparison with those spectra data previously reported. Compound 1 and 2 exhibited antibacterial activity against Gram-positive bacteria, Staphylococcus aureus and Streptococcus mutans with MIC values of 51.2; 48.8; 72.5; dan 100.7 µg/mL respectively.DOI :http://dx.doi.org/10.15408/jkv.v0i0.3151

Abstract

Sirih merah leaf (Piper crocatum Ruiz & Pav) is a natural material that has the potential to be used as a natural antibacterial agent in treating dental caries caused by Streptococcus mutans because it is known to contain secondary metabolite compounds that have antibacterial properties that can inhibit the activity of glucosyltransferase and glucan-binding protein (Gbp) enzymes produced by S. mutans. This study was conducted to determine the antibacterial activity of Sirih merah leaf extract against S. mutans using the Kirby-Bauer method and to predict the potential molecular activity of antibacterial compounds contained in Sirih merah leaves in inhibiting the growth of S. mutans bacteria in silico using the molecular docking method. Antibacterial activity testing of Sirih merah leaf extract fractions obtained from methanol extract showed that fractions 7 and 10 are active fractions because they can inhibit the growth of S. mutans at the highest concentration of 10% with a strong inhibition zone category. The active fractions were then analyzed by the LC-HRMS method to obtain active compounds. The results of the in silico molecular docking test showed that the active compounds of Sirih merah leaves have the potential to interact with the GtfB and GbpC enzymes of S. mutans, where the best binding energy in the interaction of cafedrine compounds is -8.75 kcal/mol and -9.27 kcal/mol. The docking results were validated through a molecular docking process using native ligands with RMSD values of 1,861 Å and 3,170 Å.
