This study evaluated the anticonvulsant and anxiolytic effects of morin-loaded PLGA-chitosan nanoparticles (Morin-PLGA-CS NPs) in male Wistar rats. <b>Methods:</b> Morin-PLGA-CS NPs were synthesized using a modified single emulsion-solvent evaporation method followed by CS coating. NPs were characterized by dynamic light scattering (DLS), scanning electron microscopy (SEM), and in vitro drug release analysis. Adult male Wistar rats received intraperitoneal injections of free morin (25 mg/kg), Morin-PLGA-CS NPs, diazepam (1 mg/kg), blank NPs, or vehicle. Behavioral assessments included the open-field test (OFT), elevated-plus maze (EPM), novel object recognition (NOR) test, and pentobarbital-induced sleep test. Anticonvulsant activity was evaluated using PTZ-induced seizure latency. Cytokine concentrations in cortical and hippocampal tissue lysates were quantified by ELISA at 12 h post-PTZ. Hippocampal relative mRNA expression of Nrf2, HO-1, GFAP, and Iba1 was quantified by quantitative real-time PCR (qRT-PCR). <b>Results:</b> Morin-PLGA-CS NPs demonstrated a hydrodynamic diameter of 221.6 nm, a zeta potential of +23.3 mV, and an encapsulation efficiency of 81%.

One established remedy is the prodrug strategy: the covalent attachment of a bioreversible promoiety that regenerates the parent drug in vivo. The same conjugation can move a molecule in either direction along the hydrophilic-lipophilic axis: lipophilization raises membrane and oil solubility for permeation-limited or topical uses, whereas hydrophilization raises aqueous solubility. This review addresses hydrophilization and asks whether enzymatic (biocatalytic) synthesis can replace conventional chemistry in building water-soluble prodrugs. We examine, class by class of hydrophilic promoiety (polyol and sugar esters, glycosides, amino acid esters, poly(ethylene glycol), and ionizable phosphates), the biocatalytic toolbox (lipases, acyltransferases, glycosidases, and glycosyltransferases), the molecular determinants of its selectivity, the pharmacokinetic consequences of hydrophilization, and the translation of these reactions to process, benchmarking each against the corresponding chemical route. A three-part test emerges: enzymes suffice, and frequently surpass chemistry, wherever an accessible hydroxyl or carboxyl must be functionalized regioselectively on a promoiety bearing no competing group and a moderate solubility gain is required. This is the regime of polyols, most sugars, and glycosides, with drug-conjugate aqueous-solubility increases of roughly 4-fold to 5500-fold; chemistry remains necessary for ionizable phosphates, amino acid esters, and PEG carriers. Two gaps limit translation: the field's central 'green' claim is asserted far more often than it is measured (E-factor, PMI, life-cycle assessment), and in vivo pharmacokinetic data for enzymatically synthesized hydrophilizing prodrugs remain almost absent.

This review synthesizes current evidence on pediatric busulfan PK, exposure-guided dosing, and the transition from conventional therapeutic drug monitoring (TDM) to model-informed precision dosing (MIPD). <b>Methods</b>: We conducted a focused narrative search of PubMed, Web of Science, and ScienceDirect from database inception to August 2026 and synthesized relevant literature on pediatric busulfan PK, exposure-response relationships, TDM, population PK modeling, Bayesian methods, and emerging quantitative approaches. <b>Results</b>: Body size is the primary determinant of busulfan clearance in children, while maturation, underlying disease, concomitant medications, and pharmacogenetic variation may contribute additional variability, although their effects are inconsistent across populations. Busulfan exposure is associated with HSCT outcomes and toxicity; however, reported targets differ by dosing regimen, conditioning intensity, disease category, and exposure metric. Reliable exposure estimation requires accurate sampling records and validated bioanalysis, while limited sampling strategies may improve clinical feasibility. Integrating population PK models with Bayesian estimation enables individualized dose adjustment, although routine implementation requires external validation and compatibility with local workflows. Emerging approaches, including physiologically based PK, PK/PD, and machine learning models, show promise but lack sufficient clinical validation for routine use. <b>Conclusions</b>: TDM remains the foundation of pediatric busulfan precision dosing, while MIPD provides a framework for integrating patient characteristics, measured concentrations, and validated models. Standardized workflows, population-appropriate exposure targets, prospective validation, and evidence of improved clinical outcomes are essential for broader implementation.</p>","PeriodicalId":19894,"journal":{"name":"Pharmaceutics","volume":"18 9","pages":""},"PeriodicalIF":6.9,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13610923/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149063536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant-mediated synthesis of silver nanoparticles (AgNPs) has attracted interest because plant extracts can provide phytochemicals that mediate nanoparticle reduction, capping, and stabilization. This review critically evaluates recent studies on plant-mediated AgNPs for wound-healing applications, focusing on botanical and extraction variables, synthesis conditions, physicochemical properties, formulation strategies, administered exposure, safety, and biological outcomes. Across the 34 included publications, 14 directly assessed a process-to-property relationship and only two assessed a process-to-performance relationship; none directly assessed a property-to-performance relationship or established a complete process-to-property-to-performance chain. The reviewed studies suggest that plant-mediated AgNPs may reduce microbial burden, modulate inflammation, mitigate oxidative stress, and promote cell migration, re-epithelialization, collagen remodeling, and angiogenesis. However, batch-to-batch variability, incomplete reporting of experimental details, over-reliance on ultraviolet-visible (UV-Vis) spectroscopy for optimization, inadequate evaluation of formulation stability, inconsistent dose reporting, and limited molecular validation of proposed mechanisms remain major factors limiting translation. By evaluating plant-mediated AgNP-based wound-healing systems through a process-property-performance framework, this review summarizes recent advances and highlights key considerations for improving reproducibility, comparability, and translational relevance.</p>","PeriodicalId":19894,"journal":{"name":"Pharmaceutics","volume":"18 9","pages":""},"PeriodicalIF":6.9,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13610848/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149063756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
