The present study aimed to explore an ideal delivery system for triptolide (TPL) by utilizing the thin-film hydration method prepare drug-loaded, folate-modified mixed pluronic micelles (FA–F-127/F-68–TPL). Scanning electron microscopy and atomic force showed that drug-loaded had a spherical shape with small particle size, average of 30.7 nm. Cell viability experiments FA–F-127/F-68–TPL significantly reduced HepG2 cell viability, exhibiting strong cytotoxicity. Its cytotoxicity was markedly enhanced compared bare TPL. Nile red (Nr) used as model drug FA–F-127/F-68–Nr further validate its tumor-targeting cellular uptake capability. After coincubation cells, multifunctional microplate reader intracellular fluorescence intensity increased, indicating could more effectively enter cells. A nude mouse subcutaneous hepatocellular carcinoma constructed. Following tail vein injection FA–F-127/F-68–Nr, imaging FA–F127/F-68–Nr target tumor tissue, even if entering small-sized challenging, it be excreted through urine. Nude mice were treated injections (45 µg/kg) every other day 21 days. results growth transplanted tumors slowed, no significant difference In summary, exhibits advantages low cost, excellent biological properties, active/passive targeting capabilities, notable against liver cancer inhibition growth. Significantly, FA–F-127/F-68–TPL, despite challenges in insignificant EPR effect, can efficiently via kidneys, thereby preventing release during prolonged circulation potential damage normal tissues.

Lung cancer, a deadly malignancy, often employs Docetaxel (DTX) as chemotherapy option. However, DTX non-selective distribution limits its therapeutic effectiveness due to adverse side effects. This study aims develop novel folate-targeted albumin polyester nanocarriers (FA-DTX-APs) encapsulating for precise delivery, enhancing lung cancer treatment efficacy. FA-DTX-APs were meticulously crafted utilizing the thin-film dispersion technique and subsequently evaluated their physicochemical characteristics, encapsulation efficiency, drug release profiles. To assess biological properties, anti-tumor efficacy, biosafety in context of comprehensive series hemolysis assays, cellular studies, animal experiments conducted. exhibit nanovesicle properties with size (223.65 ± 6.83) nm, potential (26.76 3.15) mV, encapsulate high efficiency (96.19 3.27%) loading capacity (9.75 0.38%). enable tumor-targeted delivery slow over long period time, faster acidic environments. By efficiently targeting entering cells, effectively hinder growth (P < 0.05), demonstrating superior effects biocompatibility enhanced safety 0.05). introduces FA-DTX-APs, an innovative nanocarrier characterized by exceptional safety. It successfully targets cells deliver sustained, slow-release manner, ensuring prolonged tumor-killing As such, hold immense promise nanoagent therapy.

Patients with treatment-refractory/relapsing germ cell tumors (GCTs) have a dismal prognosis due to lack of any effective therapy. Moreover, the efficacy newly approved targeted therapies remains unexplored for cisplatin-resistant GCTs. Previously, it was demonstrated that folate receptor α (FRα) is overexpressed in many tumor types and efficiently by antibody-drug conjugate (ADC) mirvetuximab soravtansine (MIRV) cancers.

Despite improvements in therapeutic approaches like immunotherapy and gene therapy, cancer still remains a serious threat to world health due its high incidence mortality rates. Limitations of conventional therapy include suboptimal targeting, multidrug resistance, systemic toxicity. A major challenge current oncology therapies is the development new delivery methods for antineoplastic drugs that act directly on target. One approach involves complexation antitumor with cyclodextrins (CDs) chitosan (CS) as an attempt counteract their primary limitations: low water solubility bioavailability, diminished vitro vivo stability, dose-dependent All those drawbacks may potentially exclude some candidates from clinical trials, thus integration into smart systems or drug-targeting technologies must be implemented. We intended overview drug based regard diagnosis management.
