Organelle-specific engineering and rational design of NLCs for targeted delivery to subcellular compartments, including the mitochondria, lysosomes, nucleus, endoplasmic reticulum (ER), and Golgi apparatus, are comprehensively discussed in this review. Strategic physicochemical modifications, such as particle size optimisation, surface functionalization with targeting ligands (e.g., TPP, TAT, NLS, KDEL), ceramide-mimetic components, and incorporation of pH or redox-responsive lipids, achieve organelle-specific localization, enabled by coupling chemistries like bio-orthogonal click reactions and EDC/NHS activation. High-resolution imaging modalities (CLSM, TEM, cryo-EM), co-localization quantification (Pearson's and Mander's coefficients), LC-MS/MS, FERT, FRAP, imaging flow cytometry, and differential scanning calorimetry (DSC) are used to validate targeting efficiency and formulation integrity analytically. Particle size, zeta potential, encapsulation efficiency, crystallinity, and release behavior are included in critical quality attributes (CQAs) that are optimised systematically using Design of Experiment (DoE) within a quality-by-design (QbD) framework. Physiologically based pharmacokinetics (PBPK) modelling and spatial lipidomics for assessing biodistribution and pharmacodynamic impact are used as preclinical translation, incorporating bioanalytical method validation. Endosomal entrapment, interspecies variability, and GMP-compliant challenges are the key translational and regulatory bottlenecks addressed in this review. Transformative potential for NLC-based precision medicine includes converging dual-organelle targeting, multi-stimuli responsiveness, emerging AI-guided design tools, and continuous manufacturing platforms. Redefining the landscape of intracellular therapeutics towards clinically viable organelle-targeted formulations through cutting-edge innovations is consolidated in this review.</div></div>","PeriodicalId":15600,"journal":{"name":"Journal of Drug Delivery Science and Technology","volume":"114 ","pages":"Article 107590"},"PeriodicalIF":4.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our attempt to translate this formulation into a product suitable for use in formal pre-clinical safety pharmacology studies, we uncovered a problem. In this report, studies have demonstrated that Cu mediated CX5461 encapsulation within DSPC/Chol (55:45 mol%) and DMPC/Chol (55:45 mol%) liposomes can lead to instability of CX5461. Chromatographic analysis revealed that CX5461 degradation increases as the incubation temperature increased from 40 °C to 60 °C. The change in CX5461 structure results in the emergence of new peaks detected by HPLC and this is associated with a reduction in the parent drug. The rate of CX5461 degradation was influenced by incubation time and liposome lipid composition. When encapsulated in the DSPC/Chol:Cu(CX5461) liposome formulation, just 1 h of incubation at 40 °C or 60 °C resulted in greater than 50 % CX5461 degradation. This degradation was associated with a 1.7-fold and a 3.8-fold decrease in the CX5461 to liposomal lipid ratio within 1 h at 40 °C and 60 °C, respectively. When the CX5461 formulation was prepared using DMPC/Chol liposomes, CX5461 was less prone to degradation. Significant decrease in the CX5461 to liposomal lipid ratio for this formulation required 6 h of incubation at 40 °C or 60 °C. Surprisingly, even after complete degradation of CX5461, the degraded compounds were therapeutically as active as parent CX5461 based on <em>in-vitro</em> cytotoxicity studies. This suggested that the biologically active portion of CX5461 was maintained even after Cu-mediated degradation. Regardless, the extent and rate of degradation preclude the pharmaceutical development of the copper formulation as the active ingredient instability poses significant (perhaps insurmountable) challenges for chemistry, manufacturing, and control documentation. To overcome this limitation, we shifted to zinc as an alternative metal to complex CX-5461. Preliminary data demonstrate that Zn(CX5461) enables efficient liposomal encapsulation while preserving chemical stability.</div></div>","PeriodicalId":15600,"journal":{"name":"Journal of Drug Delivery Science and Technology","volume":"114 ","pages":"Article 107586"},"PeriodicalIF":4.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite extensive efforts, existing cancer therapies often yield suboptimal outcomes due to their inherent off-target toxicity and the emergence of multidrug resistance in tumor cells. Thus, there exists a pressing need to explore innovative nanotechnology-based drug delivery systems to address these challenges. The present study aimed to develop temperature and glutathione (GSH)-responsive nanocarriers to selectively deliver 5-Fluorouracil (5-FU) to the breast cancer tumor. For this purpose, 5-FU loaded temperature-sensitive solid lipid nanoparticles (SLNs) were formulated using Lauric Acid and Oleic acid-based binary mixture with a melting range of 39–42 °C. A glutathione-responsive polymeric coating of folate grafted thiolated chitosan (FTCS) was coated onto developed lipid cores and evaluated in terms of physicochemical characterization, <em>in-vitro</em> drug release in normal physiological conditions as well as in the presence of glutathione and at a temperature of 39 °C. Evaluation of anticancer activities was carried out in vitro using MDA-MB-123 cancer cell lines and <em>in-vivo</em> in a chemical-induced breast cancer rat model. FTCS-SLN-5-FU exhibited an average size of 274.6 ± 2.62 nm and zeta potential of +18.74 ± 0.22 mV as compared to non-coated 5-FU loaded nanoformulation (SLN-5-FU) with average particle size of 184 ± 20.51 nm and zeta potential of 19 ± 0.27 mV, thus confirming the successful coating of the cationic FTCS. The SEM images of formulations showed well-defined nano-sized particles. <em>In-vitro</em> drug release studies have confirmed the glutathione and temperature-sensitive behavior of FTCS-SLN-5-FU, indicating 80.32 ± 8.5 % of 5-FU release at pH 5.8, 39 °C temperature in the presence of 20 mM glutathione compared to 10.21 % ± 1.89 % of drug release at pH 7.4 during the first 24 h. Invitro anticancer activity revealed a significantly reduced viability in the case of FTCS-SLN-5-FU compared to SLN-5-FU. Similarly, <em>In-vivo</em> anticancer activity in breast cancer-induced rat models indicated significantly reduced tumor weight compared to SLN-5-FU and 5-FU.

Replacing OEO with pure carvacrol allowed for a more accurate evaluation of formulation performance, highlighting the importance of release kinetics and structural integrity, rather than over surface charge, in determining antifungal efficacy. In addition, the study emphasizes the need for careful characterization of essential oil composition post-formulation and calls for further analytical investigation into the behavior of volatile components during emulsification.

However, fenofibrate suffers from poor bioavailability due to its hydrophobic nature and negligible water solubility. The generation of nanosuspension with increased surface area is one of the mechanisms to minimize this challenge. In this work, fenofibrate nanosuspension was formulated to improve the solubility of the drug. A method of hot melt emulsification followed by precipitating the hot melt into a cold aqueous medium was employed to generate the nanosuspension. Ultrasound energy and stabilizers such as Hydroxymethyl cellulose (HPMC), Polyvinyl Pyrrolidone (PVP), and Bovine Serum Albumin (BSA), along with surfactants including Tween 80 (T80) and Sodium Lauryl Sulphate (SLS), were used to control particle growth and improve the stability of the resulting suspension. Sunflower oil was used as a co-additive agent. The effects of surfactants, ultrasound energy and sonication time, drug to surfactant ratio, and sunflower oil on particle size and suspension stability were investigated. The use of ultrasound sonication during both the hot-melt formation step and the precipitation step produced smaller particle sizes. A ground mixture of fenofibrate with BSA and SLS, in the presence of 3 mL sunflower oil, produced a nanosuspension with particle sizes below 100 nm, exhibiting a relatively lower particle growth rate and improved stability. Using a lower molecular weight BSA surfactant and incorporating sunflower oil produced substantial improvement in the particle size reduction and enhancement of the suspension's stability.</div></div>","PeriodicalId":15600,"journal":{"name":"Journal of Drug Delivery Science and Technology","volume":"114 ","pages":"Article 107576"},"PeriodicalIF":4.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Docetaxel, a widely used chemotherapeutic agent, is recommended for gastric cancer treatment, either as monotherapy or in combination with other drugs. However, its clinical performance is compromised by poor physicochemical properties, systemic and dose-limiting toxicities, drug resistance, and hypersensitivity reactions associated with marketed formulations. Integrating nanotechnology into drug delivery systems offers a forward-looking solution to these persistent challenges.</div><div>In this study, a rational design strategy was applied to develop and optimize nanostructured lipid carriers (NLC) for the localized delivery of docetaxel to gastric cancer cells. The resulting NLC dispersions were thoroughly characterized regarding colloidal stability, morphology, drug incorporation, <em>in vitro</em> release, drug-lipid interactions, thermal behavior, crystallinity, and cytotoxicity. Docetaxel-loaded NLC exhibited a uniform particle size (∼161 nm) and a zeta potential more negative than −20 mV, maintaining predefined quality standards over six months of storage at 4 °C and 25 °C. Approximately 98 % of docetaxel was incorporated, likely in an amorphous or molecularly dispersed state, within the semi-crystalline lipid matrix. A slow and sustained release profile was also obtained. Cell viability analysis at 48 h revealed that docetaxel-loaded NLC were more cytotoxic than the free drug at concentrations of 0.005 nM in AGS cells and 1 nM and 10 nM in NCI-N87 cells. The enhanced efficacy was driven by DTX entrapment, with no observed toxicity from the carrier. These findings suggest that the developed NLC could be a promising delivery system for improving docetaxel therapy in gastric cancer.</div></div>","PeriodicalId":15600,"journal":{"name":"Journal of Drug Delivery Science and Technology","volume":"114 ","pages":"Article 107571"},"PeriodicalIF":4.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
