However, they encounter several obstacles in attaining exact specificity and sensitivity for disease therapies. Therefore, the development of NPs with novel approaches is critically important to improve their therapeutic efficacy. One intellectual approach is assembling and compositing them with active biomaterials like smart disease targeting peptides. Bioactive peptides derived from soybeans, are reported to involve in several physiological functions like reducing chronic diseases such as cancer, cardiovascular disease (CVD) obesity, insulin-resistance/type II diabetes, immune disorders and inflammatory diseases. Therefore, the conjugation of soy bioactive peptides with nanoparticles is a promising strategy towards engineered therapeutic nano systems. However, these conjugates of soy peptides-nanoparticles composites (SPNCs) are highly under considered. Engineered nanoparticles with peptides, captured attention as innovative therapeutic platforms. Consequently, SPNCs engineered nanostructure, have the high potential for future therapeutics as their composite/hybrid features of therapeutic NPs and soy bioactive peptides, can not only enhance their therapeutic behaviors but also can resolve their challenges they face as an individual. In this review for the first time, multimodal SPNCs with acclaimed therapeutic abilities are discussed which set a foundational understanding for the future nanotherapeutics. The foundational details of soy peptides, NPs and their chemistries and corresponding interactions with disease modes are discussed. Finally, precise guidelines for accuracy techniques to engineer SPNCs with efficient therapeutic abilities are explored. This study established the groundwork for advancement of composite soy bioactive peptides with NPs to achieve therapeutic SPNCs with high target specific abilities.</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"682 ","pages":"Article 125983"},"PeriodicalIF":5.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144707441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the potential of API–polymer phase behavior modeling as part of the design of nanoparticle (NP)-based DDS for PTX using poly(lactide-<em>co</em>-glycolide) (PLGA) and poly(lactide-<em>co</em>-glycolide)-b-poly(ethylene glycol) (PLGA-PEG) with varying molecular weights. The phase behavior of PTX–PLGA/PLGA-PEG systems, which reflects the compatibility of PTX with polymeric excipients, was predicted using the Conductor-like Screening Model for Real Solvents (COSMO-RS). To investigate the correlation between the predictions and experimental observations, PTX–PLGA and PEGylated PLGA NPs were prepared via an emulsion-solvent evaporation method with varying initial PTX amounts. The predicted trends in PTX solubility in polymeric excipients were then compared with key NP characteristics, such as drug loading, solid-state properties, and cytotoxicity in HeLa, SKOV-3, and MRC-5 cells. COSMO-RS predictions indicated limited PTX solubility in PLGA, which aligns with experimental observations, where the maximum amorphous PTX loading did not exceed 2 wt%, regardless of the polymer molecular weight. COSMO-RS modeling predicted higher compatibility of PTX with PEG, suggesting that incorporating PEG would enhance PTX loading in PEGylated NPs. This trend was corroborated by experimental findings, which showed increased drug loading capacity and slower PTX release from PEGylated NPs during cytotoxicity studies.

Traditional batch manufacturing methods, like ethanol injection and extrusion, are time-consuming, prompting a shift towards continuous manufacturing. To improve process efficiency, this study tested microfluidics, a technique widely used in lipid nanoparticle (LNP) production for nucleic acid delivery, to optimize doxorubicin liposome manufacturing, focusing on vesicle formation and remote drug loading. The formulation consisted of neutral phospholipids with minimal DSPE-PEG content and no negatively charged lipids, components typically considered critical for liposome self-assembly and colloidal stability, demonstrating that microfluidics can effectively produce stable liposomes under these challenging conditions. Detailed characterization by cryo-TEM confirmed the formation of unilamellar vesicles with internal drug nanocrystals by microfluidics. In addition, it yielded fewer multilamellar liposomes than the conventional process (18 % vs. 35 %), indicating better control of vesicle structure and lamellarity. Importantly, employing microfluidics instead of ethanol injection and extrusion reduced liposome formation time by 70 % while ensuring consistent particle size distribution, relative to ethanol injection and extrusion. Additionally, lowering the temperature during drug loading (45 °C vs. 65 °C) shortened this step by 20 %, due to faster heating and cooling. Consequently, the optimized process was at least 25 % faster and reduced cost by 15 %. Although conducted at a 100 mL scale, these improvements are expected to be amplified on an industrial scale. Hence, these findings highlight the relevance of decreasing process temperatures and underscore the potential of microfluidics to enhance the efficiency and scalability of continuous manufacturing of liposomes for small molecular weight drug delivery, a field in which this technology has been underexplored.</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"682 ","pages":"Article 125973"},"PeriodicalIF":5.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144674715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
