In the late 2000s, multiple pharmaceutical drugs that inhibited γ-Secretase and β-Secretase were synthesized, some of which advanced to human clinical trials. Unfortunately, neither γ-Secretase nor β-secretase inhibitors have been approved by the FDA due to both lack of efficacy and concerns for serious side effects.</p><p><strong>Expert opinion: </strong>While targeting of Aβ accumulation through secretase inhibitors was halted due to severe side effects, γ-Secretase modulators (GSMs) have arisen as a potential alternative approach. First-generation GSMs could modulate γ-secretase activity without affecting Notch cleavage. However, to improve potency and brain penetration, second-generation GSMs were developed to reduce levels of the amylogenic form of Aβ, Aβ42, without affecting the NOTCH signaling pathway. Several of these drugs have progressed to clinical trials, although with mixed results. The development of GSM's continues to serve as a potentially safer approach to modulating Aβ production in AD treatment.</p>","PeriodicalId":12184,"journal":{"name":"Expert Opinion on Pharmacotherapy","volume":" ","pages":"63-73"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
