DNA damage and oxidative stress generated by radiation and/or chemotherapy activate key inflammatory pathways, ultimately resulting in the destruction of the epithelial barrier, leading to microbial colonization, and ulceration. These ulcerative lesions are often extremely painful, compromising nutrition and oral hygiene, requiring intravenous nutritional support, resulting in longer periods of hospitalization and increased cost. Ulcers often increase the risk of secondary infection, disrupting cancer therapy and patient prognosis. Despite these issues, there is no approved therapy to mitigate OM. Ultrasmall (< 10 nm) spherical gold nanoparticles (AuNPs) with low toxicity offer unique size- and surface chemistry-dependent anti-inflammatory and antioxidant properties. However, physicochemical design of AuNPs, including size, capping agent, and surface charge critically influence their colloidal stability, toxicity, and therapeutic efficacy. AuNP below 10 nm demonstrate increased therapeutic efficacy due to the high surface area-to-volume ratio, however, particles smaller than 2 nm also show increased potential for inducing cellular death. Furthermore, anionic capping agents make AuNPs less toxic with increased anti-inflammatory response, while cationic particles are potent antimicrobials but toxic. Thus, surface chemistry modulation is a promising strategy to design AuNPs (< 10 nm) as potential therapeutic agents for OM. This review provides a comprehensive overview of the OM pathophysiology, discusses current interventional concepts, critically analyses the existing literature on AuNP as an anti-inflammatory, antioxidant, and antimicrobial agent and highlights the benefits and challenges associated with using AuNPs as a therapeutic agent against OM.</p>","PeriodicalId":11357,"journal":{"name":"Drug Delivery and Translational Research","volume":" ","pages":"2323-2353"},"PeriodicalIF":5.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767401","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}

Moreover, the DIP release profile, the biocompatibility of scaffolds with murine calvaria-derived pre-osteoblastic cells, and the intracellular alkaline phosphatase (ALP) assay to verify osteogenic ability were evaluated.

Indeed, the addition of DIP in concentrations up to 10% did not influence the compression modulus. Moreover, DIP-loaded scaffolds containing the highest DIP cargo (10% w/w) were able to provide sustained drug release for up to 30 days. Furthermore, cell viability, proliferation, and osteogenesis of MC3T3-E1 cells were significantly increased with the highest DIP cargo (10% w/w) compared to the control samples.

Therefore, this study investigates the effect of surfactant chain-length on the mucoadhesive, permeation, and bioavailability properties of NLCs. For this purpose, short- and long-chain sulfhydryl-modified polyethoxylated surfactants were generated to develop mucoadhesive NLCs and loaded with the model drug aprepitant (APT). NLCs were characterized and assessed for comprehensive physicochemical and biological evaluations. Moreover, in-vivo studies were performed for proof-of-concept to show enhanced oral drug bioavailability. NLCs showed particle size under 200 nm with 6.9 and 6.7% drug loading and 85 and 84% drug entrapment for short- and long-chain surfactants, respectively. The drug-loaded NLCs were safe and stable, and short- and long-chain surfactants containing NLCs exhibited 11.6- and 9.6-fold enhanced mucoadhesion, respectively. Moreover, in comparison to long-chain sulfhydryl-modified surfactant, short-chain surfactant is transported into deeper segments of mucus due to less interaction with the mucus. Similarly, short-chain sulfhydryl-modified surfactants showed significantly enhanced cellular permeation across Caco-2 cell lines. Furthermore, the long-chain sulfhydryl-modified surfactants showed 4.38-fold enhanced C<sub>max</sub>, whereas due to better diffusion and mucoadhesion properties, the short-chain surfactants exhibited 5.38-fold enhanced C<sub>max</sub>.

Currently available topical anesthetics provide insufficient pain relief due to poor drug skin permeability, especially when rapid onset is desired. Herein, our goal was to assess the speed and efficacy of local lidocaine/epinephrine/tetracaine (LET) gel enabled by STAR particles in a first-in-humans clinical trial. Twenty-two children (10 - 15 yr) were randomized in a placebo-controlled, cross-over trial to receive topical treatment of LET gel applied to the antecubital fossa for 10 or 20 min either with or without STAR particle pretreatment. STAR particle pretreatment decreased skin barrier function, demonstrated by increased trans-epidermal water loss compared to placebo (25.0 ± 8.7 g/m<sup>2</sup>h vs. 14.8 ± 4.3 g/m<sup>2</sup>h, P < 0.0001). STAR particle pretreatment followed by LET gel (STAR-LET group) resulted in decreased sharp sensations from needle probing after 10 min (51.6 ± 29.2% vs 82.0 ± 18.6%, P = 0.014) and 20 min (55.7 ± 21.8% vs 89.0 ± 15.6%, P = 0.006) compared to LET gel without STAR particle pretreatment (LET group). After hypodermic needle insertion, pain decreased at 10 min (3.1 ± 1.8 vs. 4.1 ± 1.9, P = 0.11) and 20 min (4.2 ± 1.0 vs. 5.3 ± 1.5, P = 0.02) in the STAR-LET group compared to the LET group. STAR particle pretreatment was described as comfortable and without pain by most participants. No adverse skin reactions were observed immediately after STAR-LET application or during the 7-day follow-up period. STAR particle skin treatment in combination with LET gel in children was safe, well-tolerated, and effective to rapidly reduce painful sensations associated with hypodermic needles.
