Among these, hydrophobic tagging (HyT) strategies have garnered significant interest. Carbon-based hydrophobic tags have been recognized as effective Hyts for degrading a variety of target proteins. In this study, we introduce a novel class of potential EGFR degraders for the first time, which combine Gefitinib with silicon-based hydrophobic tags (SiHyT). The most promising candidate, degrader 7, which links Gefitinib to a simple TBDPS silyl ether, has shown efficacy in degrading mutant EGFRs via the ubiquitin-proteosome system (UPS) both in vitro and in vivo. Notably, degrader 7 exhibits enhanced oral bioavailability owing to its superior metabolic stability compared to traditional carbon-based Hyts. Mechanistically, it was revealed that degrader 7 disrupts EGFR stability by dissociating the EGFR-HSP90 complex and recruiting E3 ligase, RNF149. More importantly, the potent and selective PD-L1 and BTK degraders were discovered successfully by utilizing the SiHyT strategy. The development of these innovative SiHyT compounds could broaden the repertoire of HyTs, enhancing the future design of TPD agents.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"67 23","pages":"21344–21363 21344–21363"},"PeriodicalIF":6.8,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142842380","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}

This study introduces a novel series of benzimidazoles, with the most potent analogs exhibiting IC50 values of 0.27–7.0 nM in a cell-free assay for prostaglandin (PG)E2 production. Compound 44 (AGU654) demonstrated remarkable selectivity for mPGES-1 (IC50 = 2.9 nM) over COX-1, COX-2, 5-LOX, and FLAP, along with excellent bioavailability. Metabololipidomics analysis with activated human monocyte-derived macrophages and human whole blood revealed that AGU654 selectively suppresses PGE2 production triggered by bacterial exotoxins while sparing other prostaglandins. Furthermore, in vivo studies showed that AGU654 significantly alleviated fever, inflammation, and inflammatory pain in preclinical guinea pig models, suggesting that it could be an effective strategy for managing inflammatory diseases. In conclusion, these benzimidazole derivatives warrant further exploration into new and alternative analogs, potentially uncovering novel compounds with a favorable pharmacological profile possessing significant anti-inflammatory and analgesic properties.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"67 23","pages":"21143–21162 21143–21162"},"PeriodicalIF":6.8,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849885","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}

However, the common knowledge gained by masked atom prediction dramatically differs from the graph-level optimization objective of downstream tasks, which results in suboptimal problems. Particularly for properties with limited data, the failure to consider domain knowledge results in a direct search in an immense common space, rendering it infeasible to identify the global optimum. To address this, we propose MPCD, which enhances pretraining transferability by aligning the optimization objectives between pretraining and fine-tuning with domain knowledge. MPCD also leverages multitask learning to improve data utilization and model robustness. Technically, MPCD employs a relation-aware self-attention mechanism to capture molecules’ local and global structures comprehensively. Extensive validation demonstrates that MPCD outperforms state-of-the-art methods for absorption, distribution, metabolism, excretion, and toxicity (ADMET) and physicochemical prediction across various data sizes.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"27 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142758172","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}

As a signaling molecule, cholesterol engages in discrete interactions with transmembrane, peripheral, and certain soluble proteins to control cellular responses. Accordingly, the cholesterol–protein interface is central to cholesterol-related diseases and is an essential consideration in drug design. However, cholesterol’s hydrophobic, un-drug-like nature presents a unique challenge to traditional in silico analyses. In this Perspective, we survey a collection of tools designed to predict and evaluate cholesterol binding sites in proteins, including classical sequence motifs, molecular docking, template-based strategies, molecular dynamics simulations, and recent artificial intelligence approaches. We then comment on contemporary tools to evaluate ligand–protein interactions, their applicability to cholesterol, and the yet-untapped potential of cholesterol–protein interactions in human health and disease.","PeriodicalId":46,"journal":{"name":"Journal of Medicinal Chemistry","volume":"67 23","pages":"20765–20775 20765–20775"},"PeriodicalIF":6.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.jmedchem.4c01885","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142850483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
