In addition to the target polymers, three interesting sulfur-containing cyclic byproducts were obtained and fully identified by spectroscopic methods including X-ray crystallography. These byproducts were useful for the understanding of reaction behaviors of reactive intermediates, such as the O/S exchange reaction and the backbiting reaction. The time course of the terpolymerization reaction indicated that phenyl isothiocyanate was consumed much faster than CO<sub>2</sub>. This trend is opposite to our previous observation that CO<sub>2</sub> reacted with cyclohexene oxide faster than phenyl isothiocyanate. This opposite trend is due to the difference in the selectivity-determining step in the catalytic cycles. The ring-opening of oxetane is the selectivity-determining step owing to the small ring strain of oxetane in the present case, while the reaction of an alkoxide ion with heteroallene (CO<sub>2</sub> or isothiocyanates) is the selectivity-determining step in the previous case with the epoxide.

Compound <b>10</b> potently and selectively degraded PRMT5 and its coactivator, MEP50, in concentration-, time-, and ubiquitin-proteasome system-dependent manners. It displayed much improved PRMT5/MEP50 degradation potency over MS4322, which translated to better antiproliferative effect in both breast and prostate cancer cells. Overall, we discovered a highly potent and selective PRMT5/MEP50 complex degrader, which is an invaluable chemical biology tool and a potential cancer therapeutic.</p>","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"68 8","pages":"8543–8563 8543–8563"},"PeriodicalIF":6.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
