Among them, myricetin, a naturally occurring flavonol, has emerged as a bioactive compound of significant pharmacological interest. This review provides a consolidated overview of myricetin, beginning with its methods of isolation from various plant sources, such as Diospyros kaki, Myrica rubra, and Rosa canina, and a detailed account of its in vitro and in vivo pharmacological activities, including its antioxidant, anti-inflammatory, antidiabetic, antimicrobial, anticancer, hepatoprotective, cardioprotective, and neuroprotective effects. Despite its promising bioactivities, the poor physicochemical properties of myricetin, such as its low aqueous solubility, stability, and limited bioavailability, pose substantial barriers to its clinical application. To address these challenges, this review highlights recent advancements in nanoformulation strategies, such as liposomes, solid lipid nanoparticles, nanofibers, nanostructured lipid carriers, polymeric nanoparticles, nanogels, micelles, and self-nanoemulsifying drug delivery systems, that enhance the pharmacokinetic profile and therapeutic efficacy of these methods. Furthermore, toxicological evaluations are discussed to assess its safety, supported by findings from preclinical studies. Additionally, the review summarizes the current status of clinical trials and highlights recent advancements in intellectual property through an analysis of granted patents related to myricetin. Notably, there is currently no review that comprehensively integrates all these aspects of myricetin.

This study is designed to explore the role and mechanism of PAK1 in the GEM resistance of PC cells. PAK1, ubiquitin-specific peptidase 33 (USP33), methyltransferase-like 3 (METTL3), and insulin-like growth factor-2 mRNA-binding protein 3 (IGF2BP3) mRNA levels were detected using RT-qPCR. PAK1, MDR1, MRP1, USP33, METTL3, and IGF2BP3 protein levels were examined by western blot. GEM resistance, cell viability, proliferation, apoptosis, invasion, and migration were assessed using MTT, EdU, flow cytometry, transwell, and wound healing assays. After ubibrowser database analysis, the interaction between USP33 and PAK1 was verified using co-immunoprecipitation (Co-IP) assay. Meanwhile, the interaction between METTL3 and USP33 m6A was analyzed using methylated RNA immunoprecipitation (MeRIP)-qPCR and RNA immunoprecipitation (RIP) assay. A xenograft model analyzed the effects of PAK1 on GEM resistance of PC in vivo. PAK1 was upregulated in GEM-resistant PC tissues and cells. PAK1 knockdown enhanced cell sensitivity to GEM; repressed cell proliferation, invasion, and migration; and induced cell apoptosis in vitro. Mechanistically, USP33 triggered the deubiquitination of PAK1 and prevented its degradation. METTL3 stabilized USP33 mRNA through the m6A-IGF2BP3-dependent mechanism and naturally increased USP33 expression. USP33 silencing increased the drug sensitivity of PC in vivo.

To establish the antiviral and neuroprotective potential of DADS against JEV. The present study explored the neuroprotective and antiviral activities of DADS in JEV-challenged SH-SY5Y cells in pre-, post-, and co-treatment approaches. Further, the study also investigated the nature of interaction between DADS and four drug targets of JEV such as envelope protein, NS3 helicase, NS3 protease, and NS5 RdRp using virtual screening. In plaque yield reduction assay, DADS significantly reduced plaque titer by 59.8% in post-treatment with median inhibitory concentrations of 165.8 µM. A similar antiviral effect was observed in an immunocytochemistry assay in post-infection treatment mode. The in vitro antiviral activity of DADS was further supported by its robust binding affinity for NS3 Helicase and RNA-dependent RNA polymerase, highlighting DADS as a multi-target therapeutic agent. Significant neuroprotective activity was also observed in post-treatment methods, with cell viability of 75.87%, 79.15%, and 85.05% at 50, 100, and 200 µM concentrations, respectively. The observed neuroprotective activities of the drug may be attributed to its antioxidant and anti-apoptotic activity in JEV-challenged cells.

Mucin 1 (MUC1) initiates actin-mediated cytoskeleton protrusion movement to promote mitochondrial transfer. In this study, we aimed to investigate whether MUC1 regulates mitochondrial transfer from tCAFs to NSCLC cells. The results showed that lung cancer patients with high MUC1 expression had a poor prognosis, and MUC1 protein was significantly enriched in exosomes (EXOs) derived from tCAFs. A549 cells were treated with conditioned medium (CM) or EXOs derived from tCAFs or co-cultured with tCAFs in contact or non-contact ways. Both CM and EXOs promoted the proliferation and invasion and inhibited apoptosis in A549 cells, while MUC1-interfered EXOs inhibited A549 cell proliferation and invasion and induced apoptosis. Meanwhile, non-contact co-culture of tCAFs and A549 cells promoted proliferation, invasion, and colony formation of A549 cells, and contact co-culture further promoted malignant phenotype of A549 cells and enhanced mitochondrial function in A549 cells. Mechanism studies revealed that MUC1 promotes mitochondrial transfer from tCAFs to A549 cells by interacting with intercellular adhesion molecule-1 (ICAM1), promoting malignant phenotype of A549 cells. ICAM1 interference counteracted the effect of EXO protein MUC1 on A549 cells. Finally, lung cancer xenograft tumor models were constructed and found that EXO protein MUC1 promoted lung cancer tumor growth in vivo, while ICAM1 interference inhibited tumor growth.

Through their involvement in motor and cognitive processes, they are involved in various neurological diseases and their symptoms, including Parkinson's disease and schizophrenia. The pharmacological modification or antagonization of dopamine receptors is therefore highly relevant. Dopamine receptors have been studied across diverse conditions, yet the resulting clinical evidence is scattered and highly heterogeneous, with no structured synthesis to date. This fragmentation limits the ability to evaluate the broader clinical relevance of dopamine receptor modulation, and a synthesis of these heterogenous trials represents a research gap. By systematically mapping and summarizing available trials, this review provides an integrated overview and highlights areas where further research is needed. The aim of this scoping review was to analyze current and completed clinical studies on dopamine receptors. Because the field of dopamine receptor-targeted therapies is broad, complex, and not yet systematically mapped, a scoping review offers the methodological flexibility to capture this diversity and synthesize current knowledge. ClinicalTrials.gov was searched for trials on dopamine receptors. Studies with a focus on any dopamine receptor were included, while studies employing dopamine receptors and related medications as comparators were excluded. Search results were evaluated based on the condition, the type of intervention, the study location, the sponsor, and the outcome. Two hundred forty-five. trials on dopamine receptors were identified. One hundred ninety-two (78.4%) trials were interventional trials and 53 (21.6%) were observational studies. Ten trials were terminated before completion. More than one-third of the studies (38.3%) were conducted in the USA.
