Herein, we implemented a strategy that combines drug repurposing with synergistic therapy to identify potential inhibitors targeting PBP2a's allosteric site from an FDA-approved drug database. Initially, retrospective verifications were conducted, employing different Glide docking methods (HTVS, SP, and XP) and two representative PBP2a structures. The combination of Glide SP and one representative PBP2a conformation showed the highest efficacy in identifying active compounds. The optimized parameters were then utilized to screen FDA-approved drugs, and 15 compounds were shortlisted for potential combination therapy with cefazolin, an ineffective cephalosporin against MRSA. Through biological assays—checkerboard, time-kill assays, and live/dead bacterial staining—we discovered that four compounds exhibited robust bactericidal activity (FICI < 0.5) compared to both untreated control and monotherapy with cefazolin alone. Scanning electron microscopy (SEM) confirmed that while cefazolin alone did not cause visible damage to MRSA cells, the combination treatment markedly induced cell lysis. Additional MM-GBSA studies underscored the strong binding affinity of mitoxantrone to the allosteric site.

Although many MurA inhibitors have been discovered, only fosfomycin is still used as a MurA inhibitor in clinical practice. Owing to the long-term use of fosfomycin, the emergence of fosfomycin resistance is worrisome. Therefore, it is still necessary to discover new MurA inhibitors with different types of action than fosfomycin.

However, the specific role of moscatilin in clear cell renal cell carcinoma (ccRCC) and its underlying molecular mechanisms have not been fully studied. This study aims to fill this gap by demonstrating through a series of experiments that moscatilin can effectively inhibit the proliferation and migration of ccRCC and induce its apoptosis process. More importantly, we found that moscatilin can also trigger ferroptosis in ccRCC, a process accompanied by significant increases in Fe<sup>2+</sup>, MDA (a lipid peroxidation product), and ROS (reactive oxygen species) levels, as well as decreases in mitochondrial membrane potential and GSH (glutathione) levels. These changes strongly suggest a key role for moscatilin in inducing ferroptosis. To further explore its underlying mechanism, we speculate that moscatilin may inhibit the phosphorylation level of the JAK–STAT signaling pathway, thereby blocking the function of the key protein SLC7A11 in the ferroptosis signaling pathway, which promotes the occurrence of ferroptosis. This discovery not only reveals a new mechanism of moscatilin in the treatment of ccRCC but also provides new ideas for the development of related drugs in the future. In summary, based on the important discovery that moscatilin can induce ferroptosis in ccRCC, we have reason to believe that moscatilin has the potential to become a new type of drug for the treatment of ccRCC.</p>\u0000 </div>","PeriodicalId":143,"journal":{"name":"Chemical Biology & Drug Design","volume":"105 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595438","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}

The aim is to determine whether TSA enhances the osteogenic differentiation of BMSCs damaged by dexamethasone (DEX) through the ERK1/2 –CREB signaling pathway. BMSCs were treated with varying concentrations of DEX (0.1–30 μM) and TSA (0.04–5 μM) for 18 or 36 h. Cell viability was assessed using the MTT assay. Osteogenic differentiation was evaluated through Alizarin Red S staining and quantified by qRT-PCR for osteogenic markers such as Runx2 and ALP. Apoptosis was measured by Annexin V-FITC/PI staining and TUNEL/DAPI co-staining. The ERK1/2-CREB signaling pathway was examined using Western blot and immunofluorescence. TSA at 5 μM significantly bolstered BMSCs viability and osteogenic differentiation, reversing the deleterious effects of 30 μM DEX. TSA pre-treatment decreased apoptosis and ROS levels, and importantly, it enhanced the ERK1/2-CREB signaling pathway, as evidenced by increased phosphorylation of ERK1/2 and CREB. The ERK1/2 inhibitor PD98059 and siCREB abrogated TSA's protective effects, highlighting the pathway's significance. These findings indicate that TSA, through the ERK1/2-CREB axis, provides a protective strategy against DEX-induced impairment in BMSCs.
