The potential of this approach is limited to proteins that can be readily ubiquitinated and relies on having a ligand with the various E3 ligases. Here, we describe a new methodology for targeted protein degradation that directly recruits a protein of interest to the proteasome for degradation. We generated bifunctional molecules that incorporate a small molecule ligand into a subunit on the 26S proteasome that recruits the protein directly for degradation. ByeTAC degradation requires binding to Rpn-13, a nonessential ubiquitin receptor of the 26S proteasome, and the protein of interest and does not have to rely on the E ligase cascade for ubiquitination. The ByeTAC methodology demonstrates the application of directly recruiting a protein to the proteasome via interactions with Rpn-13 for degradation.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"135 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849912","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}

In our previous study, sinomenine derivative 3a was obtained, which demonstrated potential anti-AA activity by targeting CTLs with low toxicity. In this study, a novel metabolite, 3a-M1, was identified with optimized bioavailability from 3a metabolism, which exhibited a more notable effect in alleviating anemia symptoms, suppressing bone marrow CTLs activation, and improving hematopoietic function in immune-mediated bone marrow failure mouse models. In vitro experiments demonstrated that 3a-M1 directly inhibited CTLs activation and their killing function; the underlying mechanism was at least in part mediated by the selective ferroptosis of overactivated CTLs via the IP<sub>3</sub>R/ORAI pathway.

High-resolution protein cocrystal structures revealed an unexpected interaction between the thalidomide moiety and Trp81 on the first bromodomain of BRD4. The inability to form a ternary complex provides a potential rationale for the lack of degrader activity with these compounds, some of which have remarkable affinities close to those of (+)-JQ1, as low as 65 nM in a biochemical assay, vs 1.5 μM for their POI ligand, ISOX-DUAL.

The plasticity of its catalytic domain and unique allosteric regulation by substrates or external or intramolecular factors facilitate the identification of highly selective USP7 inhibitors. These inhibitors can engage distinct ubiquitin-binding sites through covalent or non-covalent mechanisms. Despite its therapeutic promise, no USP7 inhibitors have entered clinical trials, underscoring the urgent need for novel therapeutics.
