Abstract

Background: Diabetes Mellitus (DM) is a complex chronic disease characterized by increased blood glucose. The incidence of this disease is rising, especially type 2 diabetes which is caused by insulin resistance in the body. SUR1-Pancreatic KATP Channel is a receptor as an antidiabetic target because its inhibition process can increase insulin production so that it can reduce blood glucose in people with type 2 diabetes. Objective: This study aims to identify the in-silico activity of the SUR1-Pancreatic KATP Channel macromolecules. Methods: Identification of macromolecular binding sites using Protein Plus software, then carried out molecular docking using AutoDock software, where the formed molecular interactions are further identified using the BIOVIA Discovery Studio software. Results: After determining the macromolecular binding site, the RMSD value was 1.253, allowing for further molecular docking. Molecular docking showed that the Ligands of mangostin (α, β, γ-mangostin) and sinensetin derivatives had a good affinity, namely α-mangostin -6,31 kcal/mol; β-mangostin -5.78 kcal/mol; γ-mangostin -6.17 kcal/mol and sinensetin -4.75 kcal/mol. Conclusion: The affinity sequence in the docking process for the SUR1 KATP channel macromolecules is α-mangostin > γ-mangostin > β-mangostin > sinensetin. The highest affinity for the docking process on the macromolecule SUR1 KATP channel was α-mangostin with a value of ΔG -6.31 kcal/mol Ki 23.65 μM.

Abstract

Background: Myristica fragrans Houtt. (Myristicaceae family), with the main content of myristicin, has been immensely used in herbal medicine. Standardization is essential to ensure the safety of natural extracts and the quality of herbal medicines using various chemical analysis techniques. Method validation is necessary to ascertain the reliability and reproducibility of the method. Myristicin is a member of the phenylpropene group, a natural organic compound found in small amounts in nutmeg fruit, which has pharmacological effects. Objective: This study aims to determine the myristicin content in nutmeg fruit using TLC-Densitometry. Methods: Determination of myristicin in nutmeg fruit extract was performed using TLC-Densitometry with silica GF254 as stationary phase, mobile phase n-hexane: ethyl acetate (8:2 v/v), and spot visualized at 285 nm. In this study, the content of myristicin in nutmeg fruit was determined using compendial methods (AOAC), thus requiring method verification with parameters including selectivity, linearity, precision, LOD, and LOQ. Results: The validation of this method showed good linearity and selectivity with y = 0.0001x + 0.0226 (r = 0.9996) and 1.53 (>1.5), respectively. The LOD and LOQ results were low with values of 0.11 μg/spot and 0.33 μg/spot, respectively. The percentage coefficient of variation for precision was below the requirement value of not more than 4%. The average myristicin content in nutmeg fruit extract was approximately 0.0017 ± 0.0003% (w/w). Conclusion: The developed method was valid and sensitive for the quantification of myristicin content in nutmeg fruit.

Abstract

Background: Red ginger (Zingiber officinale var. rubrum) and aromatic ginger (Kaempferia galanga L.) are traditional Indonesian medicinal plants with proven pharmacological activity, but their poor aqueous solubility requires formulation strategies to enhance solubilization and physical stability. Objective: This study aimed to optimize and evaluate a Self-Nanoemulsifying Drug Delivery System (SNEDDS) combining red ginger and aromatic ginger. Methods: The optimization was conducted by varying the oil-to-Smix ratio and extract concentration, while the internal Smix composition (Tween 80: PEG 400 = 1:2.8 w/w) remained constant to isolate the effect of oil–surfactant proportion. Virgin coconut oil (VCO), Tween 80, and PEG 400 were used as the oil phase, surfactant, and co-surfactant, respectively. Three formulas were prepared based on oil-to-Smix (w/w): Formula A (1:4.68, 500 mg extract), Formula B (1:10.6, 500 mg extract), and Formula C (1:10.6, 460 mg extract). Physical characterization included visual observation, centrifugation, particle size, polydispersity index (PDI), and transmittance before and after thermodynamic stability tests. Results: Formula A was unstable and exhibited precipitation. Before stability testing, Formula C showed improved dispersion, with a 41.5% reduction in droplet size and a 79.9% decrease in PDI relative to Formula B. After stability testing, Formula C demonstrated markedly better performance, including an 85.5% smaller droplet size, 81.4% lower PDI, and a 2.4% increase in transmittance compared with Formula B. These quantitative improvements indicated that Formula C exhibited more optimal solubilization capacity and physical stability. Conclusion: This study concludes that extract concentration and the oil-to-Smix ratio significantly influence SNEDDS characteristics, and Formula C represents the most favorable formulation for further development.

Abstract

Background: Jatropha curcas extract has been identified as a promising herbal remedy for various skin disorders. However, its application is limited by its low water solubility and poor skin permeability. Nanotechnology-based strategies provide a way to overcome these limitations. Objective: This study aimed to develop a new drug delivery system for J. curcas extract as a topical treatment for skin conditions. Methods: J. curcas extract was obtained through maceration. The system included a Carbopol 940-based gel and a J. curcas extract (JCE 10% w/w) nanoemulsion (NE) created using a high-energy method with an ultrasonic homogenizer. The appearance, pH, viscosity, spreadability, particle size, polydispersity index, and zeta potential of the nanoemulgel were assessed to verify its physical properties. Results: The optimal formulation produced a dark green nanoemulgel with a distinctive leafy smell and a semi-solid texture. Physical characterization of the JCE-NE-gel included a pH of 6.3, particle size of 142.67 nm, polydispersity index of 0.248, zeta potential of -23.23 mV, viscosity of 87.881 cP, and spreadability of 6.13 cm. Stability testing showed no significant differences after accelerated stability testing and thermal cycling. Conclusion: The study demonstrated that J. curcas extract (JCE-NE-gel) was successfully incorporated into a nanoemulgel formulation (F4), showing excellent physical properties and stability.
