Abstract

Polymorphism in drug compounds is a significant phenomenon in pharmacy because it affects physicochemical properties such as solubility, stability, and bioavailability, which impact the effectiveness and safety of drugs. X-ray diffraction (XRD) is one of the methods that can be used to identify and analyze the polymorphic properties of drug compounds. This article reviews the utilization of XRD in various studies, showing that this method is effective for identifying polymorphism, detecting changes in crystal forms, monitoring crystalline phase transitions, and characterizing the formation of new crystalline phases. Although very useful, XRD has limitations in detecting amorphous phases and requires optimal sample preparation. For more comprehensive results, XRD is often combined with other techniques such as DSC and FTIR. Overall, XRD plays an important role in drug development and quality control, and this technology is expected to continue evolving, including its ability to directly monitor the crystallization process to enhance drug quality and stability.

Abstract

Chalcone compounds are aromatic ketones and enones that have been found to have several activities, such as antimalarial, antioxidant, anti-inflammatory, anticancer, antiviral, anti-HIV, antifungal, antihyperglycemic, and carboxygenase inhibitors. A ligand's bioactivity can be predicted through in-silico tests using molecular docking. Molecular docking studies are conducted to study the interaction between ligand and receptor and identify the receptor's active site that matches the ligand when the ligand and receptor bind in a stable complex. This study can be a preliminary test before conducting in vitro and in vivo tests. This narrative review aims to analyze information on the bioactivity of chalcone-derived compounds and their derivatives through an in silico molecular docking approach in the form of binding affinity values and amino acid residues that bind. The method used is a literature study of 13 research articles found through the Semantic Scholar and Springer Link databases. The review results showed that the new compounds derived from chalcone compounds have a good range of bioactivity, as seen from the binding affinity values, which show lower values when compared to other test ligands and referenced ligands. The functional groups that have an important role in the interaction between ligands and proteins between ligands and receptors are triazole, methoxy, amine, halogen, carbonyl, hydroxyl, and thiol groups bound to the reactive structure of the α,β unsaturated ketone aromatic ring in the structure of the chalcone compound. The compounds that show promising activity can be further investigated as new drug candidates.

Abstract

Diazinon is a commonly used organophosphate insecticide in agriculture, but its persistence in water and soil presents significant health and environmental concerns. This study investigates the photocatalytic removal of diazinon from aqueous solutions using zinc oxide (ZnO) nanoparticles activated by visible light irradiation. ZnO was chosen due to its excellent photocatalytic properties, including a direct band gap (~3.1 eV), strong oxidative capability, chemical stability, and non-toxic nature, making it a superior candidate for visible-light-driven environmental remediation. Photocatalytic degradation under sunlight was also assessed for comparison. Key operational parameters, such as photocatalyst dosage, solution pH, initial diazinon concentration, and irradiation time, were systematically optimized. The highest degradation efficiency degradation was achieved with 20 mg of ZnO, neutral pH, 30 mg/L an initial concentration, and 60 minutes of irradiation. Kinetic analysis revealed that the process followed zero-order reaction kinetics (k = 1.118; R2 = 0.9962). Notably, visible light irradiation was more effective than sunlight in degrading diazinon. These findings provide important details about the potential of ZnO nanoparticles as an efficient, low-cost, and environmentally friendly photocatalyst for remediating pesticide-contaminated water under sustainable energy conditions.
