Several MK2-inhibitors have been developed in recent years to combat its effects on cancer. However, inadequate solubility, insufficient cellular permeability, systemic toxicity-mediated side effects, and low bioavailability have severely impeded the advancement of MK2-inhibitors to clinical trials. This void necessitates research to develop less toxic and more bioavailable potent MK2-inhibitors in HNSCC. In the present article, we have evaluated the in-vitro efficacy, in-vivo single-dose acute toxicity, and in-vivo pharmacokinetic profiling of recently developed PfBS (pyrrolone-fused benzosuberene) MK2-inhibitor analogues against HNSCC. The PfBS MK2 inhibitor analogues impeded HPV+ and HPV- HNSCC cell proliferation and two-dimensional migration. Moreover, MK2-inhibitors lowered HNSCC cell clonogenic survival in a dose-dependent manner, significantly enhancing radiation-induced cell death via exerting radio-sensitization effects. Furthermore, γ-H2AX immunostaining revealed that PfBS analogues impaired DNA damage repair in HNSCC cells exposed to gamma radiation. In mice, PfBS MK2 inhibitors at 300 mg/kg were well-tolerated without any lethal effects. Pharmacokinetic studies showed that PfBS analogues exhibited rapid absorption (Tmax), adequate plasma concentration above the micromolar level (C0 or Cmax), limited tissue distribution (Vd), and faster elimination from the body (Cl). Overall, this study summarizes in-vitro efficacy, safety, and pharmacokinetics of developed MK2-inhibitors and opens doors for pharmacodynamics and mechanism of action study of most effective leads in HNSCC.</p>\u0000 </div>","PeriodicalId":11291,"journal":{"name":"Drug Development Research","volume":"86 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Myeloid differentiation protein 2 (MD2) and serum amyloid A1 (SAA1) are involved in various diseases, including infections, inflammatory diseases, and cancer. We investigated their role in PTX resistance to identify potential anti-TNBC drugs. In this study, we investigated the changes of SAA1 in TNBC tissues and its role in PTX-induced TNBC cells. Our study revealed SAA1 expressed in the human TNBC subtype and TNBC cells. PTX and CIS induce SAA1 in TNBC cells, and PTX induces inflammatory response via SAA1 in TNBC cells. MD2 blockade increased the sensitivity of TNBC cells to PTX, which was related to the expression of SAA1 during PTX-caused damage of TNBC cells. In further research, SAA1 binds to MD2, promotes the combination of TLR4/MD2 and TLR4/MyD88, activates the NF-κB signaling pathway, and creates the inflammatory microenvironment for cancer cells.

Despite its potential, the underlying pharmacological effects to skin inflammation remain unclear. Therefore, this study aimed to reveal the curcumin's molecular targets and its potential in suppressing skin inflammation using network pharmacology and in vitro experiments. A total of 7,393 and 239 targets related to curcumin and skin inflammation, respectively, were obtained from public databases. By drawing a Venn diagram, 216 common targets were identified as candidate targets. These targets were subjected to gene function and pathway enrichment analyses, and a protein-protein interaction network was established to investigate curcumin's impact on inflammation. The gene functions were mainly associated with inflammatory response, membrane raft, and serine-type endopeptidase activity. The NF-κB and MAPK pathways could be the major pathways through which curcumin acts on skin inflammation. Ten major targets of curcumin in the treatment of skin inflammation were identified: AKT1, TNF, EGFR, APP, MMP9, STAT3, HIF1A, PTGS2, EP300, and GSK3B. Molecular docking analysis results showed high binding affinity of curcumin to PTGS2, GSK3B, HIF1A, and STAT3, which may contribute to its inhibitory effect on skin inflammation. In vitro experiments confirmed curcumin's anti-inflammatory effect on inflammation by reducing the expression levels of NO, IL-1β, and IL-6 in LPS-induced HaCaT cells.

As resistance mechanisms evolve rapidly, the need for innovative solutions has never been more critical. This review delves into the transformative role of AI-driven methodologies in antibiotic development, particularly in targeting drug-resistant bacterial strains (DRSBs), with an emphasis on understanding their mechanisms of action. AI algorithms have revolutionized the antibiotic discovery process by efficiently collecting, analyzing, and modeling complex datasets to predict both the effectiveness of potential antibiotics and the mechanisms of bacterial resistance. These computational advancements enable researchers to identify promising antibiotic candidates with unique mechanisms that effectively bypass conventional resistance pathways. By specifically targeting critical bacterial processes or disrupting essential cellular components, these AI-designed antibiotics offer robust solutions for combating even the most resilient bacterial strains. The application of AI in antibiotic design represents a paradigm shift, enabling the rapid and precise identification of novel compounds with tailored mechanisms of action. This approach not only accelerates the drug development timeline but also enhances the precision of targeting superbugs, significantly improving therapeutic outcomes. Furthermore, understanding the underlying mechanisms of these AI-designed antibiotics is crucial for optimizing their clinical efficacy and devising proactive strategies to prevent the emergence of further resistance. AI-driven antibiotic discovery is poised to play a pivotal role in the global fight against antimicrobial resistance.
