Abstract

Controlling Aedes aegypti mosquitoes with chemical insecticides causes resistance on humans, environmental residues, and contaminates food and water. Polygala paniculata is a potential alternative to insecticides in controlling Ae. aegypti. This study aimed to determine the effect of the Insecticide Score of P. paniculata extracts on the mortality of Ae. aegypti mosquitoes based on KT50. A total of 20 mosquitoes for each concentration were used to examine the effectiveness of 10%, 15%, 20%, and 25% concentration of P. paniculata extracts compared to a positive and a negative control with four replications. The results showed that P. paniculata extracts had an effect on Aeaegypti mosquito mortality. There were significant differences in mortality rate between concentrations (Kruskal-Wallis test, p = 0.001). Spearman Correlation test gave a p-value of 0.008 < 0.05. Similarly, there was a weak but significant correlation between plant extract concentration and mortality (Spearman correlation: r = +0.312, p = 0.008). The 10% and 15% concentrations had KT50with Insecticide Scores of 1 and 2, respectively, implying that both had no knockdown effect. A 20% concentration had a KT50 with an Insecticide Score of 3, indicating a weak knockdown effect, whereas a 25% concentration had KT50with an Insecticide Score of 5, signifying a quick knockdown effect. These results show that a 25% concentration has a quick knockdown time on Ae. aegypti mosquitoes. Therefore, extract P. paniculata extract at a concentration of 25% has a potential for use as a bio-insecticide in controlling Ae. aegypti mosquitoes.

Abstract

In traditional Melayu Riau medicine, the jackfruit parasite plant, also known as Macrosolen cochinchinensis (Lour.) van Tiegh, has been utilized as a remedy for coughs, a treatment for cancer, a diuretic, and to speed up the recovery process after giving birth. Through in vitro and in silico testing, this investigation aims to learn more about the bioactive components and antibacterial activity of n-hexane, ethyl acetate, and ethanol obtained from the extracts of the jackfruit parasite plant (Macrosolen cochinchinensis (Lour.) van Tiegh. The disc diffusion method was used for the in vitro testing, and the molecular docking method was used for the in silico testing. Both were conducted against Staphylococcus aureus ATCC 12600 and Escherichia coli ATCC 25922. Each sample extract was prepared in three different concentrations (10%, 30%, and 50%), while chloramphenicol was used as the positive control. Inhibition zones of the extract against E. coli bacteria were found to be as follows: 6 mm, 8.4 mm, and 10.6 mm for the n-hexane extract; 8.2 mm, 10.7 mm, and 15.6 mm for the ethyl acetate extract; and 6 mm, 7.1 mm, and 14.1 mm for the methanol extract. The results of the test to determine the extract's antibacterial activity were as follows: The following is a list of the zones of inhibition that the extract has against S. aureus bacteria: 6 mm, 7.5 mm, and 13.7 mm in diameter for the extract of n-hexane; 12.8 mm, 14.2 mm, and 19.2 mm in diameter for the extract of ethyl acetate. Test results of 7.2 mm, 9.3 mm, and 15.3 mm were obtained for the methanol extract. In accordance with the findings of the study, the ethyl acetate extract of jackfruit parasite leaves exhibited the highest level of antibacterial activity, as measured by an inhibition zone diameter of 19.2 mm, when tested on S. aureus bacteria. In the meantime, the results of molecular docking of punicalin and rutin, which have been reported to have activity against proteins 6GOS.pdb and 1OJZ.pdb, have potential as antibacterials because they form 5 and 9 hydrogen bonds with important amino acids of the target protein, with cDOCKER values of -57.9239 and -88.3993, respectively. It suggests that punicalin and rutin can inhibit the growth of bacteria.

Abstract

Covid-19 has caused more than 14 million confirmed cases and more than 6 hundred deaths as of 21 July 2020 globally. However, there is no approved drug to treat the disease. Xanthone is a potential therapeutic option for the virus that have been tested using molecular docking. There were 12 of xanthone compounds and its derivatives which have been docked against two protein crystals, 2GX4.pdb and 6FV1.pdb, which obtained two potential compounds of hydroxyxanthone derivatives with sulfonate and chloro substitution. These compounds are potentially developed into one of the agents for the treatment of infection COVID-19 disease. Based on energy data and interactions with amino acid residues when compared with its own native ligands, namely NOL and E8E, respectively. Energy docking and energy docking interactions are equal to - 43.3057and - 45.5805 Kcal/mol respectively, during interactions with amino acid residues in the form of Gly 142, His 163, Cys144, Glu166, Gln164 and His 41. Based on these two data, it can be concluded that trihydroxyxanthone compounds 4 and 8 with chloro and sulfonate substitution are very potential to be developed as drug agents for Covid-19 disease therapy through protease inhibition.

Abstract

Three types of cyclopentanone derivatives have been synthesized from aromatic aldehyde and ketone derivatives under a base condition through aldol condensation. These cyclopentanone products were 2,5-dibenzylidene-cyclopentanone (a), 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (b), and 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (c) which has a yield of 63-99%. The chemical structure of these compounds were determined using UV, IR and NMR spectroscopy. In order to clarify the role of hydroxyl and amine moieties, toxic, antioxidant and anti-inflammatory activities were carried out. The toxic test indicated that the compounds showed strong toxicity. In addition, the presence of hydroxyl and amine groups on both rings of curcumin increased the antioxidant and anti-inflammatory activities.

Abstract

This study aims to synthesize chalcone derivative compounds (E)-1-(4-Chlorophenyl)-3-(3-Hydroxyphenyl)Prop-2-En-1-One (CX) in alkaline conditions through a stirring method using a magnetic stirrer. 4 chloro acetophenone was reacted with 3 hydroxy benzaldehyde using ethanol p.a as a solvent and 60% KOH as a base catalyst. Furthermore, purification was carried out by recrystallization using ethanol p.a solvent and a yield of 72.67% was obtained. The purity test of the compound was carried out using TLC and melting point tests. Furthermore, the reaction compound was tested for activity as an antidiabetic in silico. In silico studies were carried out to predict the interaction of compounds with proteins (1GFY.pdb). In silico studies show that the cDOCKER energy value obtained by the original COL ligand is higher than the CX compound obtained. The results of the COL ligand docking with the 1GFY protein have a cDOCKER energy value of -49.4051 kcal/mol and have four hydrogen bonds that bind to the important amino acid residues Gly220, Arg221, Ser216 and Asp181. While the docking of the synthetic compound ligand (CX) produces a cDOCKER energy value of -29.293 kcal/mol and shows 3 hydrogen bonds to the important amino acid residues Ser216, Asp181 and Lys120. Based on these results, it is known that the CX compound has the potential to be used as an antidiabetic candidate compound.

Abstract

The goal of education is to actively develop students' potential by establishing a learning environment and process. Most students still find learning chemistry in high school or trade school to be challenging. One way for universities to help schools grow and enhance secondary school students' skills is through the Assisted School Program. Students in this program receive training to help them develop a broad perspective, expose them to the working world, and encourage their innovative spirit. Students at the target school responded favorably to this exercise, as evidenced by the average proportion of their responses on the indicators of interest, responsiveness, and satisfaction that met positive criteria. Students at this aided school, SMK Negeri 2 Pekanbaru, responded actively to the activities 94% of the time, whereas SMK Negeri 1 Tualang received the fewest replies (72%). In general, student responses regarding their level of enthusiasm in the targeted school activities are excellent. Overall, the guided inquiry method's student replies were rated as good. This is demonstrated by the percentage of each statement falling into the very good category, the overall student response rate of 81.88%, and the pre-test and post-test results, which showed that it had an impact on students' knowledge growth as indicated by the higher post-test scores compared to the pre-test score.

Abstract

Ficus heteropleura Blume, commonly known as mistletoe on oil palm, is a semi-parasitic plant that grows on oil palm trees. This study aimed to investigate the secondary metabolite profile, determine of total phenolic content, and evaluate antibacterial activity of ethyl acetate extract of F. heteropleura leaves. Extraction was performed using a grade maceration method. Qualitative phytochemical screening was conducted to identify major classes of secondary metabolites, and total phenolic content was quantitatively determined using the Folin–Ciocalteu method with gallic acid as the standard. Ethyl acetate extraction yielded 19.27 g of crude extract. Phytochemical analysis revealed the presence of steroids, flavonoids, saponins, and tannins. The total phenolic content was determined to be 35.730 mg GAE/g. UV-Vis spectrophotometric analysis showed characteristic absorption peaks at 475.0 nm and 432.8 nm, indicating the presence of phenolic pigments with conjugated C=O groups and a peak at 666.3 nm associated with chlorophyll, contributing to the green coloration. FTIR analysis confirmed the presence of functional groups such as O–H, C≡C, C=O, C=C, and C–O. Antibacterial activity demonstrated that the ethyl acetate extract exhibited strong inhibitory effects against Staphylococcus aureus and Escherichia coli, with average inhibition zone diameters ranging from 5 to 10 mm, indicating strong antibacterial activity.
