Rational Design of Multifunctional Tacrine Derivatives as Candidates for the Treatment of Alzheimer and Parkinson Diseases

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
We present a set of multifunctional tacrine derivatives, designed with the CADMA‐Chem protocol, aimed for Alzheimer and Parkinson diseases. Of the tacrines designed, TAC‐674 and TAC‐678 are the best candidates to act as multifunctional antioxidants and neuroprotectors for Alzheimer and Parkinson diseases, respectively.

Mapping Trofinetide Polypharmacology in Rett Syndrome: A Multi‐Stage Computational Analysis

open access: yesJournal of Computational Chemistry, Volume 47, Issue 21, August 5, 2026.
How can a single molecule address the complex symptoms of Rett syndrome? This computational study maps the multi‐target mechanism of trofinetide, revealing diverse modes of binding across five key receptors: GAT1, GABAA, CHRM1, AMPA, and GSK3β. From deep orthosteric anchoring to dynamic surface interactions, these structural insights provide a rational

Purification and characterization of polyphenol oxidase (PPO) from water yam (Dioscorea alata)

open access: yesCyTA - Journal of Food, 2019
Polyphenol oxidase (PPO) is responsible for the enzymatic browning of fruits and vegetables, and thus has negative effects on the quality of food. In this study, extraction and purification of PPO from water yam was performed successfully, and the ...

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

open access: yesAdvanced Science, Volume 13, Issue 47, 24 August 2026.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy

open access: yesAdvanced Science, Volume 13, Issue 45, 13 August 2026.
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...

Metabolomics of Eryngium heterophyllum by UHPLC‐QToF‐MS and In Silico Insights Into Potential Metabolic Syndrome Targets

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Eryngium heterophyllum has 85 metabolites according to nontargeted UHPLC‐QTOF‐MS profiling, with flavonoids and phenylpropionic acids emerging as significantly related bioactive families. In silico compound–disease–target networks connect 31 metabolites to inflammation, diabetes, obesity, and cardiovascular disease associated with metabolic syndrome ...

Comparative Phytochemical Profiles and Antioxidant Potential of Green and Variegated Morphotypes of Alternanthera bettzickiana Under Optimized Extraction Conditions

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Green and variegated Alternanthera bettzickiana morphotypes were compared after optimizing extraction (Box–Behnken design–RSM: 90% ethanol, 50°C, 2 h, 10 mg/mL). The green morphotype had higher phenolic content, FRAP, and ORAC activity, while the variegated morphotype had higher flavonoid and anthocyanin content.
