Moreover, bactericidal time-kill kinetic studies revealed that at a high concentration of 3MIC, compound <strong>5p</strong> was capable of directly killing MRSA cells. The subsequent postcontact effect (PCE) results showed that the growth rate of viable bacteria (MRSA) was greatly impacted and did not recover in less than 24 hours, even after antibacterial agent <strong>5p</strong> was removed. The drug-like properties and ADME prediction exhibited that <strong>5m–5p</strong> obeyed Lipinski's rule of five and therefore presumably maintained moderate to good bioavailability and human intestinal absorption rate when administered orally. Mechanistic investigations have elucidated that compound <strong>5p</strong> exerted its antibacterial effect by compromising the structural integrity of bacterial cell membranes, resulting in the leakage of intracellular constituents and ultimately causing bacterial demise. Further studies <em>in vivo</em> have demonstrated that <strong>5p</strong> exhibited potent antibacterial efficacy against MRSA in murine corneal infection models, particularly at elevated concentrations.

This article summarizes the innovative development of Fc-glycan-specific ADCs (gsADCs), which utilize the conserved Fc <em>N</em>-glycan as the anchor point for site-specific conjugation. This approach offers significant strengths, including improved ADC homogeneity and overall hydrophilicity, enhanced pharmacokinetics and therapeutic index, and potentially reduced Fc receptor-mediated side effects. Currently dozens of gsADCs are in different preclinical and clinical development stages. Notably, JSKN003 and IBI343 have demonstrated promising results in phase 1 trials and are advancing into phase 3 studies. This review discusses the advantages of Fc-glycan-conjugation, various glycan-specific conjugation techniques, and the preclinical and clinical development of gsADCs. While challenges such as increased manufacturing cost for large-scale production need continuous innovation to overcome and there are different opinions regarding the pros and cons of reduced/diminished affinities to Fc gamma receptors, ongoing research and clinical progress underscore the potential of gsADCs to renovate ADC cancer therapy.</p>","PeriodicalId":21462,"journal":{"name":"RSC medicinal chemistry","volume":" 1","pages":" 50-62"},"PeriodicalIF":4.1,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11575643/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142682724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
