In this contribution, a post-modifiable trapezoidal cage (1a) was developed to address the selective recognition of SO<sub>4</sub><sup>2-</sup> from HPO<sub>4</sub><sup>2-</sup>, as well as to cope with the difficulties of trapezoidal cages in post-modification and property variation.

This finding was further validated through molecular docking analysis and cellular thermal migration and enzyme activity experiments. The results of WRN helicase inhibition assays showed that the IC<sub>50</sub> value of compound 11 g was 6.61 µM. In summary, our study identifies 2-amino-4-(trifluoromethyl)pyrimidine derivative 11 g as potential WRN-dependent anticancer agents.</p>","PeriodicalId":708,"journal":{"name":"Molecular Diversity","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144300925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
