However, prodrug activation remains a rate-limiting step for exerting therapeutic actions, which requires to quickly reach the minimum valid concentrations of free drugs. Fortunately, we find that a natural compound (BL-193) selectively improves the chemotherapy sensitivity of breast cancer cells to podophyllotoxin (PPT) at ineffective dose concentrations. Based on this, we propose to combine prodrug nanoassembly with chemotherapy sensitization to fully unleash the chemotherapeutic potential of PPT. Specifically, a redox-sensitive prodrug (PSSF) of PPT is synthesized by coupling 9-fluorenyl-methanol (Fmoc-OH) with PPT linked via disulfide bond. Intriguingly, PSSF with a π-conjugated structure readily co-assembles with BL-193 into stable nanoassembly. Significantly, BL-193 serves as an excellent chemosensitizer that creates an ultra-low-dose chemotherapeutic window for PPT. Moreover, prodrug design and precise hybrid nanoassembly well manage off-target toxicity. As expected, such a BL-193-empowered prodrug nanoassembly elicits potent antitumor responses. This study offers a novel paradigm to magnify chemotherapy efficacy-toxicity benefits.</p></div>","PeriodicalId":8539,"journal":{"name":"Asian Journal of Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":10.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1818087624000096/pdfft?md5=7511bc92f1d69866729349b4f73ae5d9&pid=1-s2.0-S1818087624000096-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140053929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, its local application is hindered by its low solubility and poor skin permeability. To overcome these challenges, a carrier-free pure drug self-assembled nanosystem is employed, which can specifically modify drug molecules based on the disease type and microenvironment, offering a potential for more effective treatment. We designed and synthesized three distinct structures of cationic CTS-peptide conjugates, creating self-assembled nanoparticles. This study has explored their self-assembly behavior, skin permeation, cellular uptake, and both <em>in vitro</em> and <em>in vivo</em> anti-acne effects. Molecular dynamics simulations revealed these nanoparticles form through intermolecular hydrogen bonding and π-π stacking interactions. Notably, self-assembled nanoparticles demonstrated enhanced bioavailability with higher skin permeation and cellular uptake rates. Furthermore, the nanoparticles exhibited superior anti-acne effects compared to the parent drug, attributed to heightened antimicrobial activity and significant downregulation of the MAPK/NF-κB pathway, leading to reduced expression of pro-inflammatory factors including TNF-α, IL-1β and IL-8.

It mediates nuclear transfer of Smad2/Smad3 complexes and initiates the transcription of fibrosis-promoting genes. Thus, the inhibition of Smad4 expression in pulmonary fibroblasts by small interfering RNAs (siRNAs) might be a promising therapeutic strategy for IPF. Herein, we engineered exosome membranes (EM) by cationic lipid (<em>i.e.</em>, DOTAP) to load siRNAs against Smad4 (DOTAP/siSmad4@EM), and investigated their specific delivery to pulmonary fibroblasts for treating IPF in a mouse model <em>via</em> pulmonary administration.
