Development of Fourier Transform Infrared Spectrophotometric Method for Quantification of Simvastatin, Atorvastatin, and Rosuvastatin in Marketed Tablet Preparations
type: item
description: ABSTRACT. Marketed pharmaceutical dosage forms must be checked to ensure that the drug in distribution meets the quality requirements. The Fourier transform infrared spectrophotometric method will provide new innovations which are low cost, environmental friendly, simple, and rapid for analysis. The aim of this research was to develop a single analytical method that can be used to determine levels of three different statin derivatives (simvastatin, atorvastatin, and rosuvastatin) in tablet preparations. The method used in this study was Fourier transform infrared spectrophotometric, a very simple sample preparation stage by solvent extraction with minimal solvent extraction without potassium bromide and without pellet press. The specific wave numbers of simvastatin, atorvastatin, and rosuvastatin were determined between 4000 cm–1 to 650 cm–1. The Fourier transform infrared spectrophotometric method had been successfully developed and successfully applied to the determination of levels of simvastatin, atorvastatin, and rosuvastatin in marketed tablet preparations containing single active pharmaceutical ingredient. The specific wave numbers of simvastatin, atorvastatin, and rosuvastatin obtained was 1712.7 cm–1; 1660.5 cm–1; and 965.4 cm–1, respectively. The results obtained in the content determination based on the peak height and peak area fulfill the requirements for active pharmaceutical ingredient assay ranging from 90.00% to 110.00%. The developed method has also been validated for accuracy, precision, specificity, linearity, range, limit of detection, and limit of quantitation. Thus, this method can be a valid alternative method, cheap, green, easy, and fast in determination of the levels of simvastatin, atorvastatin, and rosuvastatin in tablet preparations.

The In Silico Study of Bioactive Compounds from Some Tropical Trees as Inhibitors of Papain-Like Protease SARS-COV-2
type: item
description: ABSTRACT. Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is the causal virus of the global COVID-19 pandemic. Furthermore, it is known to encode 4 structural and 16 non-structural proteins, one of which is Papain-Like protease (PLpro). This protein is an essential enzyme that plays a role in the maturation of viral polyproteins, the formation of replicate-transcriptase, and the signaling of the host's innate immune response to viral infections. To prevent the activities of PLpro, several compounds with inhibitory effects have been developed from natural sources. Flavonoid compounds from bay leaf (Syzygium polyanthum) and mahogany bark (Swietenia macrophylla), as well as phenolics from white teak bark (Gmelina arborea Roxb.), have been reported to have antiviral activities, but there are no studies on their potential as PLpro SARS-CoV-2 inhibitors. Therefore, this study aimed to investigate the PLpro SARS-CoV-2 inhibitory effects of 11 bay leaf, 3 mahogany bark, and 6 white teak bark test ligands within silico method using YASARA and PLANTS. The best test ligands obtained were epigallocatechin-3-gallate (-98.93 kcal/mol), catechin (-80.10 kcal/mol), epicatechin (-80.12 kcal/mol), and balanophonin (-83.36 kcal/mol) based on energy binding values surpassing the reference ligands ribavirin (-74.06 kcal/mol) and benserazide (-90.93 kcal/mol). Additionally, these four ligands satisfied physicochemical, pharmacokinetic, and toxicity predictions, in contrast to the natural ligand VIR251, which carries the risk of inhibiting hERG, potentially resulting in fatal outcomes. Based on the results, the compounds could be developed as effective alternative drugs in inhibiting PLpro SARS CoV-2. Keywords: Covid 19, molecular docking, Papain-Like protease, SARS CoV-

Design and Fabrication of a Microfluidic Chip Device for Colorimetric Quantitative Analysis of Albumin in Urine Matrix Solutionn
type: item
description: ABSTRACT. The existence of albumin in urine indicates kidney impairment, referred to as albuminuria. Early detection of kidney dysfunction can be done through the examination of urine albumin levels. This research aims to develop a microfluidic chip device for quantitative analysis of albumin in urine matrix solution using colorimetry with a smartphone-based device. The microfluidic chip device for albumin is tested and evaluated through functional tests and analysis of the quality of measurement data generated. The functional tests of the colorimetric system include testing the hydrophobic properties of the fluid on the material surface, fluid distribution pattern, color appearance, and leakage. The quality of measurement data is evaluated based on the predictive ability of the partial least squares regression models generated by data measurement for predicting the albumin levels accurately and precisely. A prototype of the microfluidic chip device for albumin was made from transparent acrylic material, with a 3-dimensional vertical fluid flow design consisting of two main parts: the inlet section and the colorimetric system for visual fluid observation. Based on the functional tests, it is found that the acrylic material in the colorimetric system has a hydrophilic surface characteristic with a contact angle of 61.15o. The fluid can flow and distribute well within the colorimetric system without producing bubbles. The color appearance in the colorimetric system is also visualized well without fluid leakage. On the other hand, RGB HSL data, as the digital image identity of the training and test samples, can be used as predictor variables. The method validation demonstrated acceptable sensitivity, with an LOD of 3.368 mg/dL and an LOQ of 11.825 mg/dL. Precision at 16 mg/dL showed good repeatability (RSD 0.561%, recovery 99.26%;) and reproducibility (RSD 2.147%, recovery 101.42%). These results confirm the method's reliability for albumin quantification at the tested…

Synthesis, Molecular Docking, and In Vitro Activity Test of Thioxanthenol and Nitrothioxanthone Derivatives As Anticancer Agents
type: item
description: ABSTRACT. This research aimed to compare, synthesise, study molecular docking, and test the anticancer activity of thioxanthenol, 1-hydroxythioxanthone, 4-nitrothioxanthone, and 2-nitrothioxanthone compounds through in silico and in vitro assays, highlighting their selective cytotoxicity and potential as novel anticancer scaffolds. These four compounds were obtained through reduction and nitration reactions of the thioxanthone. Thioxanthenol compound was obtained through the reduction of thioxanthone using sodium borohydride. The 1-hydroxythioxanthone, 4-nitrothioxanthone, and 2-nitrothioxanthone compounds were obtained from the nitration of thioxanthone compounds. The compounds were characterised using FTIR, GC-MS, 1H-NMR, and 13C-NMR. In vitro cytotoxicity tests were performed using microtetrazolium (MTT) assays against T47D, WiDr, and Hela cancer cell lines and the Vero cell line as normal cells. The molecular docking process was studied to determine the in silico activity of the compounds with protein targets. The reduction reaction produced the thioxanthenol compound as a yellowish-white solid in 40.63% yield. The nitration reaction produced 1-hydroxythioxanthone, 4-nitrothioxanthone, and 2-nitrothioxanthone compounds as light-yellow solids in 33.54%; 29.27%; and 31.71% yield, respectively. The synthesized compounds demonstrated selective anticancer activity against certain cancer cells. Thioxanthenol compound showed an IC50 value of 17.46 µg mL-1 on the WiDr cell line and nitrotioxanthone compound showed an IC50 value of 6.05 µg mL-1 on the T47D cell line. Molecular docking showed that the thioxanthone derivatives might act as the anticancer agent through inhibition of epidermal growth factor receptor (EGFR), P-glycoprotein, and Erα functions.

Klanceng Honey Beehive (Trigona biroi) Sunscreen Activity
type: item
description: ABSTRACT. UV radiation can cause various skin problems, including photoaging and skin cancer. Sunscreen can provide UV radiation protection. Klanceng honey bee nests may contain metabolites that could be employed as sunscreen agents. This research project investigates the sunscreen activity of the extract, n-hexane fraction, ethyl acetate fraction, and aqueous fraction of the Klanceng honey bee hive using SPF, % Te, and Tp values. Honey bee hives are extracted via maceration assisted by ultrasonic waves. As solvents for fractionation, n-hexane, ethyl acetate, and water are used. UV spectrophotometry at a wavelength of 290-375 nm was used to examine the sunscreen activity of the samples in vitro, and the SPF, % Te, and % Tp values were computed. The extract, n-hexane fraction, ethyl acetate fraction, and aqueous fraction had SPF values of 5.832, 4.464, 11.898, and 2.846, with medium, medium, maximum, and minimal protection categories, respectively. The % Te value indicates that the extract, n-hexane, and aqueous fraction do not protect anti-erythema transmission. However, the ethyl acetate fraction does. The % Tp statistic demonstrates that all samples offer sunblock category protection. Based on this, the availability of ethyl acetate fraction is the most effective defense against UV A and UV B rays, indicating that it has the most significant potential as a sunscreen agent.

N-Doped and Chemically Activated Carbons Derived from Shrimp Shells Waste as Potential Electrode Materials for Electrochemical Supercapacitors
type: item
description: ABSTRACT. Supercapacitors are widely recognized as energy storage solutions due to their high-power densities and long cycle life. Furthermore, there is growing scientific and technological interest in converting biomass waste into carbon materials for manufacturing supercapacitor electrodes. In addition to their abundance and cost-effectiveness, the appeal of carbons derived from biomass lies in their tuneable porosity, which enables the rational design of carbon materials to achieve the desired performance of supercapacitors. This work presents the synthesis of activated carbons from shrimp shells waste and its application for supercapacitor electrodes, with an activation treatment using phosphoric acid (H3PO4) and nitrogen doping (N-doped). The activator concentration was varied at 3, 6, and 9 M; while the N-doped ratios were 1:3, 1:5, and 1:7. The characteristics of activated carbon and supercapacitor electrodes was analysed with BET, SEM, CV, and GCD. The resulting materials exhibited amorphous and predominant microporous structures. Increasing the activation concentration gave smaller specific surface area, from 17.522 to 9.509 m2 g−1. The electrochemical properties of these activated carbons for supercapacitor applications were investigated by cyclic voltammetry, galvanostatic charge–discharge, with KOH electrolyte. The best activated carbon produced was mesoporous with the highest specific surface of 17.522 m2/g, obtained at 3 M H3PO4 and a nitrogen doping ratio of 1:3. At the same activator concentration and nitrogen doping ratio (3 M; 1:3), the highest capacitance was obtained 16.320 Farad, with current charging and discharging stop at 475 seconds and 1235 seconds, respectively. This work showcases the efficient and sustainable utilization of shrimp shells waste as a carbon source for supercapacitor applications and highlights their value in a circular economy.

Optimization and Characterization of Urease Immobilization from Red Lentil Seeds (Lens culinaris) Using Chitosan
type: item
description: ABSTRACT. Urease is an enzyme that plays a vital role in catalyzing the hydrolysis of urea into ammonia (NH3) and carbon dioxide (CO2). This study focuses on the isolation of urease from red lentil seeds, followed by its immobilization. The objective of this research is to optimize and characterize urease that has been immobilized using chitosan and activated with glutaraldehyde. Red lentil seeds were processed with a mortar and pestle at low temperatures (4 °C) to obtain a crude enzyme extract, which was then concentrated using 50% acetone (P50) prior to immobilization. The optimization process for P50 urease immobilization involved assessing various factors, including chitosan concentration, glutaraldehyde concentration, temperature, and the immersion duration in glutaraldehyde. The findings revealed that the optimal conditions for immobilizing P50 urease were achieved at a chitosan concentration of 0.75%, with a 2% glutaraldehyde soak at 25 °C for 2 hours, resulting in an enzyme activity of 7.042 U/g. The immobilized P50 urease demonstrated the ability to be reused up to 7 times while maintaining 51% of its initial activity. Scanning Electron Microscopy (SEM) analysis indicated morphological changes in the beads after the addition of glutaraldehyde and the enzyme, shifting from a rounded to an irregular shape. Additionally, Fourier Transform Infrared Spectroscopy (FTIR) analysis identified C-N and C=N peaks, confirming the successful incorporation of glutaraldehyde.

Selection of Four Lamiaceae Species (Ocimum americanum L., Ocimum basilicum L., Leucas lavandulifolia Sm., and Perilla frutescens (L.) Britton) as Antioxidant Sources and Metabolite Profile
type: item
description: ABSTRACT. The Lamiaceae family which are widely used in traditional medicine in Indonesia. Plants from this family are known to have antioxidant bioactivity. Therefore, in this study, an antioxidant test was carried out first as an initial screening. This study evaluated the antioxidant capacity of four Lamiaceae species: Ocimum americanum L., Ocimum basilicum L., Leucas lavandulifolia Sm., and Perilla frutescens (L.) Britton. The four Lamiaceae species extracts were evaluated for their antioxidant capacity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), cupric-reducing antioxidant capacity (CUPRAC), and ferric-reducing antioxidant power (FRAP). The highest activity extract was fractionated with n-hexane, ethyl acetate, and ethanol-water, and the results were tested for antioxidant capacity. The most active extract and most active fraction were analyzed for metabolites using liquid chromatography-mass spectrometry (LC-MS/MS). The results show that the ethanol 50% leaves extracts of O. americanum L. have the highest antioxidant capacity of about 0.439 (DPPH); 1.517 (CUPRAC); and 1.021 (FRAP) mmol ascorbic acid equivalent (AAE)/g extract. The highest antioxidant capacity from the partition results was possessed by the ethyl acetate fraction with a value of 1.109 (DPPH); 1.540 (CUPRAC); and 1.551 (FRAP) mmol AAE/g fraction. Metabolite analysis using LC-MS/MS succeeded in identifying 18 metabolites consisting of flavonoids, terpenoids, amino acids, phenolic acids, fatty acids, and other carboxylic acids.

Harnessing Nature's Colors: Combining Plant Pigments and Metal Coatings for Dye-Sensitized Solar Cell
type: item
description: ABSTRACT. This study aims to improve the efficiency of dye-sensitized solar cells (DSSCs). To overcome the recombination problem in the commonly used TiO2 semiconductor, we performed electrodeposition of ferrous metal (Fe) on TiO2. XRD characterization showed that after Fe electrodeposition, the crystal structure of TiO₂ remained in the anatase phase without significant changes compared to before deposition while based on SEM-EDS results, Fe was dispersed to form small agglomerates that functioned as metal contacts to reduce electron recombination. We also investigated the use of anthocyanins from various natural sources, including jengkol skin, senduduk fruit, mangosteen skin, and red grape skin. These anthocyanins were copigmented with salicylic acid. UV-Vis spectroscopy revealed that copigmentation caused a bathochromic shift and FTIR spectrum confirmed strong interaction between anthocyanins and salicylic acid through hydrogen bond formation. The combination of TiO2-Fe layers with pigmented dyes resulted in diverse DSSC efficiencies, with mangosteen peel showing the best performance (4.123%), followed by senduduk fruit (3.495%), grape peel (2.569%), and jengkol peel (1.925%). The increase in efficiency from 1.189% (without Fe coating) to 1.700% (with Fe coating) demonstrates the potential of this technique. The small TiO2 crystal size (about 61.8 nm) also contributes to the increased surface area, enhancing dye absorption and solar cell performance. The electrical efficiency showed that the combination of TiO2-Fe with copigmented anthocyanins from mangosteen skin produced DSSCs with the highest efficiency, demonstrating the potential of this approach to improve the performance of natural dye-based solar cells. Keywords: Co-pigmentation, dye-sensitized solar cell, Fe electroplating, natural dye.

Effect of Organic Solvents in the Preparation of Single Aged Garlic Transfersomes and Their Phytochemical Activities
type: item
description: ABSTRACT. Single Aged Garlic (SAG), a fermented product from a single garlic, has been extensively studied for its health benefits due to its allicin content. To enhance SAG's drug delivery capabilities, this study aimed to characterize transfersome formulations containing SAG, investigating their phytochemical activities and the effects of different absolute solvents. Transfersome formulations, consisting of soy-phospholipid and either Span-60 (T1) or Tween-80 (T2), were prepared using absolute ethanol (EA) or a chloroform-methanol mixture (CM). Characterization included particle size, polydispersity index (PDI), and zeta potential. Phytochemical tests assessed antioxidant activity, total phenolic content, and total flavonoid content. Results showed that T2-CM formulations exhibited the best PDI (0.372 ± 0.022), smallest particle size (T1-CM: 84.333 ± 1.762 nm), and lowest zeta potential (T2-EA: -25.667 ± 0.666 mV). Additionally, T1-CM and T2-CM formulations demonstrated superior antioxidant, flavonoid, and phenolic content compared to T1-EA and T2-EA. Transfersomes formulated with organic solvents like absolute ethanol, methanol, and chloroform exhibit promising characteristics and can effectively protect the antioxidant compounds, flavonoids, and phenols present in SAG extracts. These solvents, known for their ability to dissolve polar and nonpolar compounds, facilitate the formation of stable, well-characterized transfersomes. These findings suggest that transfersomes prepared with chloroform-methanol mixtures are more promising for SAG delivery.

Eco-friendly Sunscreen: Aloe vera and Garlic-Shallot Peel Extract Formulation for Enhanced SPF
type: item
description: ABSTRACT. In the past 5 years, research has reported that chemical sunscreen products pose risks of irritation and environmental impact, necessitating safer natural alternatives, such as eco-friendly sunscreen. This study aimed to formulate a natural sunscreen by combining Aloe vera gel with garlic-shallot peel waste extracts and evaluate their solar protection factor (SPF), physical stability, overall quality, and organoleptic-hedonic test. The Aloe vera and extracts of garlic and shallot peels were prepared using modified infusion and solvent extraction techniques. The sunscreen formulas were created in nine variations with different concentrations of natural ingredient combinations. SPF values were determined in vitro using UV/Vis spectrophotometry, and the physical stabilities were tested using the cycling method. Overall quality tests were performed using the method as described in the standard and requirements for sunscreen products in Indonesia (SNI 16-4399-1996), and the procedure for determining the organoleptic-hedonic test referred to the organoleptic and/or sensory testing instructions (SNI 01-2346-2006). The results showed that all nine formulations met most of the quality standards of sunscreen. However, the panelist preferred formulas without garlic and shallot extracts due to the prominent odor of garlic and shallot. Further studies will be performed by combining them with fragrances that panelists prefer to cover the deficiencies in unpreferred odors. Formulas with garlic and shallot peel extracts have ultra-protection SPF values, though their effectiveness decreased with increased Aloe vera concentrations. These results indicate that garlic and shallot peel waste have the potential as sustainable, environmentally friendly sunscreen ingredients with high UV protection capabilities. Keywords: Aloe vera, garlic peel, shallot peel, SPF, sunscreen

type: item
description: ABSTRACT. Due to their phytochemical constituents, Dewa leaves (Gynura japonica (Thunb.) Juel.) are often used in traditional medicinal herbs. However, in vitro and in vivo of antioxidative and anti-aging studies of Dewa leaves on yeast as a eukaryotic cell model have not been widely carried out. This study aims to determine the antioxidant, anti-aging, and antibacterial activities derived from G. japonica leaves extract. Extraction was conducted using 70% and 96% ethanol solvents, total phenolic content (TPC) was assayed using Folin-Ciocalteu method, flavonoid contents (TFC) was assayed using aluminum chloride method, antioxidant activity was tested using DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2-azinobis-3-Ethylbenzothiazoline)-6-sulfonic acid) radicals. Subsequently, an anti-aging activity test was performed on the yeast Saccharomyces cerevisiae as a model organism following antibacterial activity. The antibacterial activity test was carried out using well diffusion agar, and the Minimal Inhibitory Concentration (MIC) was determined using the microplate method. We obtained that G. japonica leaves extracted from 70% and 96% methanol solvents, have TPC of 13.14 and 22.11 mg GAE/gr extract, and TFC of 8.04 and 14.09 mg QE/gr extract, respectively. As for DPPH and ABTS antioxidant activity, D70 showed the best activity with IC50 values of 1411.36±56.35 µg/mL and 2516.10±18.77 µg/mL, respectively. The anti-aging test showed that both 70% and 96% ethanol extracts were able to maintain the yeast cell viability under H2O2 oxidative stress. Further, 70% and 96% ethanol extract also showed antibacterial activity at the best value against Staphylococcus aureus with a MIC value of 390.62 µg/mL, it means that Gynura leaves extract has a potency as antibacterial agent. The results of this study indicate that the ethanol extract of G. japonica leaves can be developed for further investigation as an antioxidant and antibacterial therapeutic agent.

Chemical Constituents from Indonesian Dysoxylum parasiticum (Osbeck). Kosterm and Their Cytotoxicity Against MCF-7 Breast Cancer Cells
type: item
description: ABSTRACT. The exploration of naturally occurring secondary metabolites from plants, which serve as direct sources or precursors for new drug development, motivates us to conduct a comprehensive investigation into their presence. Indonesia stands out as a global biodiversity hotspot, boasting a significant number of endemic species that offer a rich reservoir of untapped resources for pharmaceutical, agricultural, and environmental uses. The Dysoxylum genus, belonging to the Meliaceae family, is recognized as a vital source of secondary metabolites and is well-known for its traditional medicinal applications. Consequently, we focus on analyzing the chemical constituents found in the stem bark of one Indonesian Dysoxylum species, specifically D. parasiticum (Osbeck) Kosterm., and assess their biological activity as anticytotoxic agents. Our research identified three known compounds: a tirucallane-type triterpenoid, cneorin-NP36 (1), a seco-limonoid from the preurianin group, amotsangin A (2), and an ergostane-type steroid, 22(E)-ergosta-6,22-dien-3β,5α,8α-triol (3). The biological evaluation against the human breast cancer cell line MCF-7 revealed that compound 2 exhibited a notable inhibitory effect, with an IC50 value of 34.5 μM. The existence of a highly oxidized structure in compound 2, due to its ester substituents, highlights its effectiveness in inhibiting cancer cell proliferation, outperforming the reference drug cisplatin, which has an IC50 of 53.0 μM. These findings indicate that amotsangin A (2) is a promising anticancer agent, particularly in the treatment of breast cancer. Further studies, including in silico analysis and structural modification, are needed to enhance its cytotoxic activity and selectivity.

Electrochemistry Response of Platinum Powder Composite as Electrode for Sensor Capsaicin
type: item
description: ABSTRACT. So far, the concentration of capsaicin in food has been determined using the tongue. Several analytical methods were developed to determine the concentration of capsaicin, but they have many drawbacks such as being expensive, long analysis time, requiring hazardous chemicals, and being difficult to operate. This research aims to prepare a material that has high stability and excellent electrocatalytic activity to determine capsaicin concentration. The research was conducted by preparing powdered platinum electrodes mixed with polyvinyl chloride (PVC). The mixture of the two materials is added with tetrahydrofuran (THF), dried, and pressed so that it becomes a solid electrode which is a platinum powder composite (PPC). These electrodes are used as working electrodes for the analysis of capsaicin in food sauce. The results showed that the NaOH electrolyte was the best electrolyte for capsaicin analysis using platinum powder composite electrodes. The PPC electrode showed good test method validation results, namely recovery of 108.69%, LOD, and LOQ of 5.9 x 10-1 mM and 19.9 x 10-1 mM, respectively. The capsaicin concentration in the food sauce was 0.029 M in a 0.5 g sample. Keywords: Capsaicin, composite, cyclic voltammetry, platinum powder, sensor
