Methods: Nα-9-fluorenylmethoxycarbonyl-diphenylalanine (Fmoc-FF) peptide-based NGs loaded DOX CUR were formulated using solvent-switch method. DOX-loaded previously characterized. CUR-loaded characterized through rheology, scanning electron microscopy (SEM), dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), Fourier transform infrared (FT-IR) spectroscopy. Confocal microscopy, q-RT-PCR, ATP lite assays performed evaluate uptake delivery DOX- on Results: exhibited mean diameter approximately 204.3 nm zeta potential -34.6 mV, indicative good stability. vitro release studies revealed sustained profile over 72 h. Functional analyses demonstrated that Fmoc-FF-loaded internalized They primarily localized cytoplasm rather than early endosomes, thereby ensuring intracellular Furthermore, Fmoc-FF reduced nuclear kinetics cells, suggesting reduction dose-limiting toxicity. Comparative similar internalization delayed uptake, highlighting efficacy delivering agents.

Exosomes/MoS2 complex for targeting and effective photothermal therapy

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 31, 2025

Photothermal therapy (PTT) has been an attractive tumor treatment strategy in recent years. Two-dimensional molybdenum disulfide (MoS₂)-based nanomaterials with high photothermal efficiency is a critical candidate for PTT. However, the tumor-targeting capability extremely needs to be improved effective treatment. In this work, we combine MoS₂ nanodots exosomes, native vesicles secreted from living cells, construct novel exosomes/MoS₂ complex (MoS₂@ME) tumor-targeted Through ultrasonic self-assembly membranes, are incorporated into MCF-7 exosomes. Similar free MoS₂, MoS₂@ME shows significant conversion effect, causing nearly 100% necrosis proportion of and 4T1 cells under 1064 nm laser irradiation within 5 min (0.4 W/cm²) in vitro. particular, presents noteworthy affinity vivo studies further prove that it could accumulate at site efficiently. After intravenous injection plus NIR irradiation, temperature tumor-bearing mice reach 46°C short time (~ 2 min). Notably, prolongation time, tumors gradually increases reaches maximum (52.3°C) 8 min, which far higher than group. More importantly, PTT using exhibits much more antitumor therapy, as volume weight group significantly lower those PBS groups (P < 0.05), even disappears completely. In vitro demonstrate excellent targeting capacity achieving cancer therapy. This work expected overcome shortcomings some materials, aiming improve safety effectiveness. The exosome-incorporated design may pave new way molybdenum-based

Drug conjugates have emerged as a promising alternative delivery system designed to deliver an ultra-toxic payload directly the target cancer cells, maximizing therapeutic efficacy while minimizing toxicity. Among these, antibody-drug (ADCs) garnered significant attention from both academia and industry due their great potential for therapy. However, peptide-drug (PDCs) offer several advantages over ADCs, including more accessible industrial synthesis, versatile functionalization, high tissue penetration, rapid clearance with low immunotoxicity. These factors position PDCs up-and-coming drug candidates future Despite potential, face challenges such poor pharmacokinetic properties bioactivity, which hinder clinical development. How design meet needs is big challenge urgent resolve. In this review, we first carefully analyzed general consideration of successful PDC learning ADCs. Then, summarised basic functions each component construct, comprising peptides, linkers payloads. The peptides in were categorized into three types: tumor targeting cell penetrating peptide self-assembling peptide. We then these delivery, overcoming resistance, controlling release improving reduced non-specific To better understand druggability PDCs, discussed pharmacokinetics also briefly introduced current trials. Lastly, perspectives development oncology PDC. This review aimed provide useful information construction applications.

Abstract Molybdenum disulfide (MoS₂) nanomaterials have attracted significant interest in cancer diagnosis and therapy due to their unique physicochemical properties. Due its extensive surface area adaptable structure, MoS₂ may engage with pharmaceuticals biomolecules via covalent non‐covalent interactions. This versatility enhances the sensitivity of identifying specific biomarkers, colloidal stability, tumor‐targeting capabilities. In near‐infrared (NIR) spectrum, exhibits strong optical absorption efficient photothermal conversion, making it suitable for NIR‐driven phototherapy regulated medication release. Functionalized nanocomposites react differently tumor microenvironment, which improves treatment effectiveness by increasing drug accumulation at sites decreasing off‐target effects on healthy tissues. Recent developments MoS₂‐based detection are reviewed this study, particular attention paid uses therapy, photodynamic biosensing, bioimaging. Additionally, looks difficulties potential applications cancer.
