Abstract

Superoxide dismutases (SODs) are metalloenzymes that defend the body against reactive oxygen species and contribute to combating inflammation. Human cells have three distinct SODs, i.e., manganese SOD (MnSOD), extracellular SOD(ECSOD), and copper-zinc SOD (Cu-ZnSOD) or SOD1. The crystal structure of human SOD1 in a complex with a naphthalene-catechol-linked compound revealed hydrogen bonds and hydrophobic interaction. Catechins arepolyhydroxylated polyphenols contained in the leaves of Camellia sinensis L. This work aims to study the binding mode and molecular dynamics of two major catechins, epigallocatechin (EGC) and epigallocatechin gallate (EGCG) with human SOD1 (in complex with SBL1, a naphthalene-catechol linked compound). Both catechins demonstrated a binding mode with the enzyme, in terms of hydrogen bonds and hydrophobic interaction, similar to the native ligand (SBL1). Of the two catechins, EGC possesses a better binding affinity (docking score of -4.15 kcal/mol) for human SOD1 compared to EGCG (docking score of -4.02 kcal/mol), thus the EGC-SOD1 complex was continued in MD simulation to investigate the conformational stability and time-dependent ligand binding ability in the binding pocket. The molecular dynamics simulation confirmed that EGC is more stable than the native ligand, SBL1, with the RMSD average value of SBL1 and EGC being 1.1669 Å and 0.5607 Å, respectively. Taken together, this study confirms the antioxidant activity of catechins in C. sinensis L.

Abstract

Seawater concentrate from Pamekasan is a product with high mineral content. The mineral content analysis of Pamekasan seawater concentrate was conducted using a comparative test of results from X-Ray Fluorescence Spectrometry (XRF) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This mineral content testing used a skin moisture device. The essential minerals found in Pamekasan seawater concentrate through analysis are Mg, Cl, K, Ca, Cr, Mn, Cu, and Zn. Statistical analysis results from XRF and ICP-OES on market products showed no significant difference in average results; however, there was a significant difference in average results in the samples. The most recommended method for analyzing seawater mineral concentrate from Pamekasan is ICP-OES due to its wider detection range and lower matrix interference.

Abstract

Sargassum cristaefolium is one of 782 types of seaweed/macroalgae that grows in Indonesia and is known as one of the macroalgae with bioactive compounds having an important role in the development of nutraceuticals for disease prevention and health maintenance. Sargassum cristaefolium extract (SCE) is known for its various beneficial activities such as antimigraine by reducing levels of CGRP and inhibitor of tyrosinase activity in anti-melanogenetics. Nevertheless, due to its hygroscopic viscous extract consistency and fishy odor, a suitable formulation is required to prepare a powder form of SCE and thus could be applied in a suitable dosage form. Our current study aims to develop the extract into suitable powder raw material by applying a solid dispersion technique.  The solid dispersion of SCE was initially prepared by selecting suitable carrier agents such as Aerosil, Microcrystalline cellulose (MCC) PH 101, maltodextrin, and PVP K30 with the extract in a ratio of 1:1, and continued by the combination of the carrier agents. The best powder formula was characterized by its powder characteristic, solubility and powder flow was assessed by its angle of repose, Carr’s index and Hausner ratio.  The experiment results that the optimum formulation for solid dispersion of SCE was obtained by the combination of SCE:PVP: MCC at a ratio of 1:1:3 with a less fishy smell, and excellent powder properties. The composite mixture was estimated due to the formation of hydrogen bonds between the carbonyl group of PVP and the hydroxyl group of SCE’s compound and MCC. In conclusion, solid dispersion of SCE by employing a combination of PVP and MCC can be an alternative to prepared SCE powder with optimum humidity protection and good flowability thus suitable to proceed as solid dosage form.  Keywords: Sargassum cristaefolium, solid dispersion, PVP K30, Microcrystalline                      cellulose PH101

Abstract

Glyburide is a widely used oral antidiabetic agent for managing type 2 diabetes. Despite its long history, evolving insights into its pharmacokinetics (PK) and pharmacodynamics (PD) have highlighted knowledge gaps, especially in the context of genetic variability, drug-drug interactions, and use in special populations. This narrative scoping review synthesizes recent evidence to provide a comprehensive and updated understanding of glyburide’s PK/PD profiles.  A thorough literature search of studies published in English, including manual reference checks, was conducted. Glyburide exhibits complex pharmacokinetics, extensive absorption throughout the gastrointestinal tract, significant plasma protein binding, hepatic metabolism via CYP2C9 and CYP3A4 enzymes, and predominantly renal elimination. Its pharmacodynamic effects involve stimulating insulin secretion and enhancing peripheral insulin sensitivity. Common side effects include hypoglycemia and weight gain, while drug-drug interactions and monitoring are crucial for safe and effective use. Understanding glyburide’s pharmacokinetics and pharmacodynamics is key to optimizing diabetes management. Tailoring dosages based on patient factors can improve efficacy, minimize adverse effects, and enable personalized care. Further research on genetic influences, drug interactions, and its use in special populations is needed to refine treatment strategies and enhance safety and effectiveness.

Abstract

Unintended medication discrepancies (UMD) frequently occur during transitions of care, particularly in low- and middle-income countries (LMICs), where the healthcare system often lacks standardized protocols, integrated information systems, and trained clinical pharmacists. This narrative review aims to explore the prevalence, characteristics, and contributing factors of UMD across LMICs based on analysis of 10 selected studies. Omission was the most frequently reported type of discrepancy, especially among elderly patients with complex therapy regimens. Factors influencing the occurrence of UMD include polypharmacy, inadequate documentation, absence of medication reconciliation protocols, limited pharmacist involvement, and poor inter-facility communication. Despite systemic limitations, studies demonstrate that pharmacist-led interventions can significantly reduce the incidence of UMD, even in resource-limited settings. Comparative analysis with studies from developed countries reveals that digital tools, standardized policies, and integrated pharmacist roles greatly enhance medication safety during transitions of care. The review concludes that addressing UMD in LMICs requires a multi-faceted approach, including national policy development, pharmacist integration into clinical teams, implementation of context-appropriate digital systems, and strengthening pharmacy education. These strategies are crucial for improving patient safety and reducing preventable adverse drug events related to medication discrepancies.

Abstract

Acute inflammatory conditions such as uveitis in pets can lead to discomfort and unnecessary pain. The treatment for uveitis involves the administration of anti-inflammatory drugs, including NSAIDs or herbal remedies generally containing flavonoids. Physalis angulata Linn., known as Ciplukan, encompasses compounds exhibiting anticoagulant, antimicrobial, anti-inflammatory, and anticancer activities. Ciplukan is composed of withanolids, terpenoids, carotenoids, and flavonoids. This study was conducted to investigate the anti-inflammatory effect of the ciplukan ethyl acetate fraction (CEAF) on Wistar rats as egg white-induced inflammation models and the most effective dose. The test was carried out on 6 test groups, each consisting of 5 rats. The test groups consisted of a normal control group, a 4,5 mg/kgBW diclofenac induced group, a negative control (NC) group which were induced inflammation using egg whites, and CEAF administration at respective doses of 5, 10, and 15 mg/kgBW groups. The parameters used in this research were plant determination, phytochemical tests, measurement of edema volume, and analysis of anti-inflammatory activity. The volume of edema on the rats’ paws was measured using a plethysmometer periodically, with a total period of 6 hours. All the data in the study were analysed statistically using the One-Way Analysis of Variance (ANOVA) method and the Tukey test with 95% CI. The results indicated that the CEAF with dose of 15 mg/kgBW exhibited a percentage of edema inhibition (47,8%) closest to that of the diclofenac sodium group (61,6%). The study findings suggest that the CEAF possesses anti-inflammatory activity with the most effective dose of 15 mg/kgBW.
