Abstract

Antibiotic-resistant is a global issue. Klebsiella pneumoniae has high priority to find its antibiotic because it has extended-spectrum beta-lactamase (ESBL) enzyme that makes the bacteria easy to resist the antibiotic. The study of phytochemicals in medicinal plants is one of the efforts to find antibiotics. Indrulizia is one of the empirical medicinal plants containing flavonoids used to treat disease. The aim of this study was to analyze the potential of borage as an antibacterial agent against Klebsiella pneumoniae in silico. Docking is the method for this study using AutoDock Vina. This is an application for docking the enzyme ESBL from K. pneumoniae, referred to as SHV (sulfhydryl variable), and the metabolite second from plants. The parameters analyzed were binding free energies, inhibition constants and visualization in 3D and 2D. The free energy of binding and the inhibition constant of the native ligand are -6.7 kcal/mol and 12.118 μM. The binding free energy values ​​of apigenin 7-glucuronide and rosmarinic acid show higher potencies than the native ligand of SHV-1 (1,4-thiazepine).

Abstract

The world's energy needs generally come from non-renewable sources. In other circumstances, some research on renewable energy is being developed from a variety of different sources, one of which is biomass. Biomass changes the energy system towards the modernization of the bioenergy system by utilizing the concept of biochemical systems (BESs). A microbial fuel cell is known as one of the renewable technologies that convert biomass with the help of microbes to produce electricity. This research is based on a microbial fuel cell based on ecoenzyme Citrus reticulata known as Ecoenzyme fuel cell to determine the electrical value (voltage, current, and power density). Ecoenzyme was made from orange peel waste, molasses, and water with a ratio of 3: 1: 10 and fermented for a month. Meanwhile, the electrode device used was a pencil graphite. Some treatments were carried out to optimize the performance of the system based on the number of electrodes (one pair and three pairs), and the stirring conditions, stirring at 200 rpm and without stirring (0 rpm). The EFC system was run for four weeks (600 hours) with the highest voltage obtained at 650 mV and current at 29.55 mA. The ecoenzyme produced the most significant power density of 750 W/m2 in the treatment of 3 electrode pairs with a stirring speed of 200 rpm. The influence of electrodes and stirring in the MFC system upsurged the electrical value output by 53.7% for a pair of electrodes and 142% for three electrode pairs. Further development will continue to be done to improve the performance and output of the Ecoenzyme fuel cell system as a future renewable energy source in Indonesia.

Abstract

Soybean Fusarium wilt and root rot disease caused by a necrotrophic ascomycete pathogen, F. oxysporum, triggered severe damage to the plant tissues and organs and impacted heavy losses. Biocontrol agents, Bacillus subtilis, were commonly used to produce a broad spectrum of antifungal substances and were gradually used in biocontrol studies for plant disease management. Investigation and determination of the inhibiting mechanism of antifungal substance produced by B. subtilis on F. oxysporum should be done to protect the soybean plant. This study revealed that basal nutrient broth (NB) gives the best antifungal activity. The stationary phase of the bacterial growth curve was obtained on two days of cultivation and showed the maximum antifungal activity against F. oxysporum. Ethyl acetate (EA) extraction of bacterial supernatant generated crude EA extract, which showed half inhibition (IC50) at 306.42 µg/ml obtained from the dose-response regression curve. Post-treatment mycelia of F. oxysporum with bacterial extract were demonstrated as hyphal deformation followed by malondialdehyde (MDA) accumulation. Furthermore, cellular leakage on fungal cells that may be triggered by antifungal compounds from strain W3.15 occurred. Last, the related antifungal compounds were predicted to be epicatechin and benzophenone from the LC-MS/MS analysis of crude EA extract. Accordingly, the biocontrol agent B. subtilis strain W3.15 promises a strong potency for biofungicide development.

Abstract

A Flavonoid glycoside compound, isolated and identified from E. polyantha as myricitrin, was analyzed as a ligand for its molecular binding activity against SARS-CoV-2 protein (receptor binding domain on Spike/RBD, main protease/nsp5, EndoRNAse, RNA-dependent-RNA-polymerase/RdRp), and its receptor, ACE2, and computationally assessed via molecular docking method. This study aims to determine the potential of myricitrin in E. polyantha from Indonesia as an antiviral drug for SARS-CoV-2 through molecular docking and molecular dynamic simulation analysis. The results showed that the myricitrin had the strongest binding affinity energy towards the three important SARS-CoV-2 proteins, namely endoRNAse, main protease (3CLpro), and RdRp with ∆G values of −9.60 kcal/mol, −8.40 kcal/mol, and −8.30 kcal/mol, respectively. These values are stronger than the comparator ligands of favipiravir (−5.60 kcal/mol), atazanavir (−7.20 kcal/mol), and remdesivir (−7.70 kcal/mol). This indicated that the compound has the potential as an inhibitor against 3CLpro, endoRNAse, and RdRp of SARS-CoV-2 proteins. This result was supported by the prediction made according to the Molprobity and PASS Online web servers, which showed that myricitrin has high bioactivity potential as an enzyme inhibitor (with a score of 0.38) and antiviral (with a score of 0.704).

Abstract

Research related to SARS-CoV-2 drugs is still ongoing. In this initial research, we perform a computational approach on SARS-CoV-2 inhibitors. RNA-dependent RNA polymerase (RdRp) is one of the functional proteins in SARS-CoV-2 that can be a target for drug development, which has an essential function in the viral replication process synthesizing the RNA genome of the virus. This study used the RdRp-Remdesivir complex structure from RCSB with ID PDB 7BV2, with a resolution of 2.5 Å. Currently, Remdesivir is under the clinical trial phase as a Covid-19 drug. In this study, we tested a thousand natural Indonesian compounds used as SARS-CoV-2 RdRp inhibitors obtained from the Indonesian natural compounds database (HerbalDB). The first stage of this computational analysis was pharmacophore modeling structure-based drug design. The natural compounds were analyzed based on their steric and electronic similarities to Remdesivir. A molecular docking simulation was then performed to obtain binding energy and bond stability to produce natural compounds that can inhibit RdRp SARS-CoV-2. The final stage was the molecular dynamics simulation that explored the conformational space of natural compounds and proteins. The ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) test was carried out on the five best compounds to obtain these natural compounds' computational pharmacology and pharmacokinetics. The simulation identified Sotetsuflavone (CID: 5494868) from Cycas revoluta, Grossamide (CID: 5322012) from Cannabis sativa, and 6-Hydroxyluteolin-6,7-disulfate (CID: 13845917) from Lippia nodiflora are the best compounds that can inhibit RdRp SARS-CoV-2. These potential compounds can then be tested in-vitro and in-vivo in the future.

Abstract

In this research, ketoprofen was used as a drug model in the preparation of chitosan nanoparticles as a potential drug delivery system through the ionic gelation process with tripolyphosphate (TPP). The particle size analysis (PSA) revealed that the average particle size, polydispersity index (PI), and entrapment efficiency of chitosan nanoparticles prepared with oleic acid were 253.7 nm and 0.375 with drug entrapment efficiency of 73.30%. Those prepared with poloxamer 188 were 242.94 nm and 0.302 with drug entrapment efficiency of 87.89%. Scanning electron microscopy (SEM) analysis showed that the shapes of the nanoparticles, both prepared with oleic acid and poloxamer 188, were intact and spherical. Fourier transform infrared spectroscopy (FTIR) indicated several differences between the spectra of chitosan- and ketoprofen-loaded chitosan nanoparticles; for example, a new peak at the wavenumber 1409/cm indicated the presence of electrostatic interaction between the carboxyl group of ketoprofen and the amino group of chitosan. The chitosan nanoparticle suspension prepared with poloxamer 188 showed smaller increases in turbidity and viscosity than that prepared with oleic acid after 34 d of storage.
