Metal-organic frameworks (MOFs) are porous crystalline materials composed of metal ions and organic ligands. By varying the combinations of metal centers and ligands, their structural properties, adsorption performance, and stability in aqueous environments can be tuned. Owing to these characteristics, MOFs have attracted attention as promising materials for environmental analysis and separation technologies. In this study, several MOFs with different metal ions and ligands were synthesized and evaluated for their adsorption performance for bensulfuron-methyl, a sulfonylurea herbicide. Among the tested MOFs, MIL-53(Al) exhibited the highest recovery. The results indicate that adsorption performance depends on the combination of metal ions and organic ligands. Full article

A novel 3,6-dicarbonyl-substituted derivative of 2-chloropyrazine has been synthesized for the first time via regioselective dilithiation using lithium 2,2,6,6-tetramethylpiperidide (LiTMP) and subsequent trapping with methyl benzoate. The structure was unambiguously confirmed through Sonogashira coupling and diagnostic NMR analysis, establishing selective substitution at both the 3- and 6-positions. This result demonstrates that symmetrical 3,6-functionalization of 2-chloropyrazine is feasible under mild conditions, overcoming long-standing limitations of multiple metalations in electron-deficient heterocycles and opening new pathways for the synthesis of polyfunctional pyrazine frameworks.

Developing predictive models for drug efficacy is challenged by the complexity and heterogeneity of bioassay data. Here, we present LIFE.PTML, which is a methodology integrating drug Lifecycle (L), Information Fusion (IF), Encoding (E), Perturbation Theory (PT), and Machine Learning (ML) to predict compound activity across diverse experimental conditions. Using a dataset of 3748 molecule–assay combinations targeting calmodulin (CaM) and related proteins, LIFE.PTML combines chemical and protein descriptors, quantifies experimental variability via perturbation operators, and trains non-linear classifiers, including XGBoost and Gradient Boosting. XGBoost achieved the best performance, with 88.9% test accuracy and an ROC AUC of 0.959, while feature importance analysis highlighted contributions from both drug- and protein-level descriptors. The results demonstrate that LIFE.PTML provides a robust, flexible, and interpretable framework for predictive chemoinformatics, facilitating the integration of multi-source data for drug discovery applications.

This study investigates the application of natural chitosan as an efficient adsorbent for the removal of heavy metals from aqueous solutions. Experimental results showed that Mn(II), Co(II), and Ni(II) ions were effectively retained on the chitosan surface. Kinetic analysis revealed a preferential adsorption order of Co(II) > Mn(II) > Ni(II), following a pseudo-second-order model with rapid kinetics. Equilibrium adsorption capacities were influenced by initial concentration, temperature, and pH. Thermodynamic analysis indicated that the adsorption process was exothermic and physical in nature. Overall, chitosan proved to be a promising and cost-effective adsorbent for water decontamination. Full article

Nuclear receptors are ligand-activated transcription factors that, in response to lipophilic hormones, vitamins, and dietary lipids, regulate numerous aspects of mammalian physiology. Bile acid receptors represent well-defined targets for the development of novel therapeutic approaches for metabolic and inflammatory diseases. The farnesoid X receptor (FXR) was identified as an orphan steroid receptor-like nuclear receptor, and its activation is crucial in many physiological functions of the liver. A vital function of FXR is to influence the amount of bile acids in hepatocytes by reducing bile acid synthesis, stimulating the bile salt export pump, and inhibiting enterohepatic circulation, thereby protecting hepatocytes from toxic bile acid accumulation. FXR activation induces distinctive changes in circulating cholesterol in animal models and humans. We present an evaluation of the interaction of various obeticholic acid analogs and other bile salts by studying their binding energies and receptor-ligand interactions using AutoDock 4.2.6 software. The results open the possibility of using new alternatives by deriving structures at position 3 of the steroid nucleus. Full article

The parasitic disease malaria necessitates novel drug targets due to increasing Plasmodium falciparum resistance. The purpose of this work was to investigate the antimalarial properties of four metabolites, namely catechin (Y10), catechin-3-gallate (Y11), 4-methoxyphenyl acryl aldehyde (Y12), and 4-hydroxy-3-methoxy acryl aldehyde (Y13), derived from Tapinanthus globiferus, a traditional medicinal plant. Docking studies with important Plasmodium aspartic proteases, Plasmepsins I and II, showed good binding affinities, and Y11 showed the best binding affinity and a critical interaction with the catalytic dyad of Plm-II. The ADMET profile showed drug-likeness with low toxicity. These findings therefore position these metabolites, particularly Y11, as promising lead compounds for the development of antimalarial drugs.

Depression is a debilitating neuropsychiatric disorder and a leading cause of disability worldwide, with current therapeutic options often limited by delayed onset of action, inadequate efficacy, and undesirable side effects. The quinoline scaffold, a privileged structure in medicinal chemistry, has been reported to possess a wide spectrum of pharmacological properties, including central nervous system (CNS) modulation. In this study, two novel 2,4-diphenylquinoline derivatives—CMPD1 [2-(4-methoxyphenyl)-4-phenylquinoline] and CMPD2 [2-(2,4-dichlorophenyl)-4-phenylquinoline]—were rationally designed based on structure–activity relationship (SAR) insights and synthesized via the Friedländer condensation of appropriately substituted anilines with carbonyl precursors. Purification was achieved through recrystallization, and structural confirmation was performed using Fourier-transform infrared (FT-IR) spectroscopy, proton nuclear magnetic resonance (NMR), and carbon-13 NMR spectroscopy, confirming the expected chemical shifts and diagnostic signals for quinoline derivatives. The pharmacological activity was evaluated using murine models for antidepressant screening: the Forced Swim Test (FST) and Tail Suspension Test (TST). Both compounds produced statistically significant reductions in immobility time compared to the control group (p < 0.05), with CMPD2 showing slightly enhanced activity. The results suggest that electron-donating and electron-withdrawing substituents influence antidepressant potency, potentially through modulation of CNS receptor binding. These findings validate 2,4-diphenylquinoline derivatives as promising antidepressant leads, meriting further optimization, in vivo pharmacokinetic studies, and mechanistic investigations to establish their clinical translation potential.

The interaction between the styryl dye 4-{(E)-2-[4-(dimethylamino)phenyl]vinyl}-1-methylpyridinium iodide (DASPI) and cucurbit[7]uril (CB[7]) in aqueous solution was studied by optical spectroscopy methods. Due to negatively charged portals, cucurbit[7]urils can form complexes with cationic styryl dye. This complexation alters the photophysical properties of the dye, such as absorption and fluorescence. It was previously found that the formation of 1:2 inclusion complexes leads to a shift in the absorption band. Such changes were previously attributed to protonation of the dye. To explain this effect, we hypothesize that it arises from the influence of the electrostatic field generated by the negatively charged portals of cucurbit[7]uril on the conjugated π-electron system of the dye.

Diabetic retinopathy (DR), an eye disease that is a threatening cause of irreversible blindness, always challenging to detect and diagnose on time. There are many ophthalmic invasive procedures which exist in medical science for the diagnosis of oculi (eyes). These all require highly skilled medical practitioners with operational knowledge of diagnosing sensitive organs like the retina and its tiny vessels. Due to the dearth of retinal specialists, the eye’s organs’ sensitivity, and the complexity of retinal therapy, invasive procedures are time-consuming, costly, and have slow progress. The fundus images are the visual information of the rear part of the retina. The progression of lesions around the retinal tissue’s surface causes the electric signals to not able to reach at the visual cortex, thus causing blurry vision or vision loss experienced by patients. The older methods using retinal fundus images for diagnosing lesions and symptoms of DR take time, causing delays in treatment and hence reducing the chance of success. Therefore, for early diagnosis, using fundus or retinal images can save the required effort and time of both doctors and patients. Artificial intelligence (AI) techniques have the capability to learn the tissue structures of the eye’s anatomy and to provide an analysis of the disease through the retinal fundus images. This process consists of operations, first apply the image preprocessing techniques followed by segmentation and filtering, then classify the disease using the artificial intelligence-based model. The proposed model trained over a dataset of DR images, for the prediction of accurate results, followed by deciding if the diagnosis by the model is correctly classified or not using the Explainable AI (XAI) algorithm. The rapid growth and better outcome of machine learning and deep learning algorithms are reasons to adopt, enhance the early diagnosis and treatments of patients. Full article

Alzheimer’s disease (AD) is a neurodegenerative disease that accounts for more than 80% of dementia cases worldwide. This a neurological disorder that encompasses various stages of development (mild, moderate, or severe cognitive impairment), including certain psychological and behavioral syndromes such as depression, psychosis, and aggression. The main drug classes currently used to treat AD are acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. Advancements in bioinformatics and chemometrics have positioned the in silico approach as a pivotal tool in identifying novel therapeutic compounds.Therefore, we conducted a study to evaluate the effects of various newly developed N-substituted 5-chloro-2(3H)-benzoxazolone derivatives on AchE. The aim of this research paper was to utilize in silico ADMET profiling to investigate the potential of natural analogs as inhibitors of AchE, using computational techniques such as swissadme. Analysis of selected ligands with the highest affinity for the target was performed to evaluate ADME properties. The calculation of ADME properties proved that these ligands follow the rules of Lipinski, Veber, and Egan and confirmed the docking results, indicating that they are probably the best inhibitors. Furthermore, they could be utilized to create novel pharmaceutical medicines with which to treat individuals with AD. Full article

Reverse micelles (RMs) are versatile nanostructures traditionally formed in low-polarity organic solvents, but the need for greener alternatives has limited their broader applicability. Here, we demonstrate for the first time that a hydrophobic Natural Deep Eutectic Solvent (NADES), prepared from a simple 1:1 mixture of camphor and menthol (CM), can act as the continuous external phase for RM formation. Remarkably, CM dissolves the benchmark surfactant sodium dioctyl sulfosuccinate (AOT) at concentrations up to 0.5 M without co-surfactants and supports water solubilization up to W₀ = [H₂O]/[AOT] = 5, yielding thermodynamically stable systems. 1H and DOSY NMR analyses reveal clear structural rearrangements of the micellar interface, confirm the encapsulation of water in the polar core, and provide quantitative evidence of size modulation as a function of W₀. The resulting CM/AOT/water assemblies represent the first example of NADES-based reverse micelles, offering an easily prepared, sustainable, and biocompatible platform. This breakthrough opens new perspectives for the development of green self-assembled systems with promising applications in areas such as food technology, pharmaceuticals, and nanomedicine.
