Thus, active processes, physiologically necessary for nutrient uptake, like receptor-mediated transcytosis have become popular targets for drug transport. One such receptor is the transferrin receptor 1 (TfR), being highly expressed at the BBB. Immunoliposomes targeting the TfR were loaded with rosuvastatin to improve the therapy of SynGAP1-associated epilepsy. The rational of using rosuvastatin is based on its function downregulating the Ras-Raf-MEK-ERK pathway, which is upregulated in excitatory neurons in patients with SynGAP1-related disorders. However, rosuvastatin shows poor BBB permeability. Therefore, immunoliposomes decorated with anti-TfR antibody Ox26 and its single-chain variable fragment (scFv) were prepared and characterized. Immunoliposomes could be prepared reproducibly with a size of about 125 nm, were not hemolytically active and showed colloidal stability in plasma for 2 h. They exhibited a high uptake into endothelial cells which was not altered in presence of the natural ligand transferrin. <em>In vivo</em> application of fluorescently labeled immunoliposomes demonstrated a long plasma half-life and accumulation in brain capillaries. In comparison to unmodified liposomes, Ox26- and scFv-immunoliposomes showed a 2.8- and 2.5-fold improved transfer of rosuvastatin into brain tissue, suggesting successful passage of the BBB.</div></div>","PeriodicalId":12024,"journal":{"name":"European Journal of Pharmaceutics and Biopharmaceutics","volume":"214 ","pages":"Article 114799"},"PeriodicalIF":4.4,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340034","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}

While it has shown promising effects in several disease models, high lipophilicity and strong metabolism limit its therapeutic use to local injections and topical administration. Moreover, high concentrations of capsaicin cause severe adverse effects. Thus, the present study aimed to synthesize a novel phenylalanine-derived prodrug of capsaicin that would utilize L-type amino acid transporter 1 (LAT1) for its delivery. The proposed prodrug strategy aimed to improve capsaicin’s therapeutic effects in the brain and pancreas, where LAT1 is expressed. The results showed that the cellular uptake into microglia, astrocytes, and pancreatic β-cells increased up to 250-fold by a LAT1-mediated delivery. In the <em>in vivo</em> pharmacokinetic study, more stable drug delivery into the pancreas and brain was observed in mice. By the prodrug design, the exposure time was prolonged from 30 min to 90 min, and peak concentrations of capsaicin were lowered.
