However, conventional ATP-competitive inhibitors are severely limited by dose-limiting metabolic toxicities caused by wild-type PI3Kα inhibition. To circumvent these limitations, the drug discovery landscape is rapidly shifting toward mutant-selective allosteric inhibitors designed to spare physiological signaling and expand the therapeutic window.Areas covered: Utilizing the Cortellis Drug Discovery Intelligence (CDDI) database, this review evaluates patents of PI3Kα mutant-selective inhibitors disclosed between 2021 and 2025. The analysis focuses on structural features, pharmacological profiles, and medicinal chemistry strategies employed to achieve high selectivity for oncogenic mutants over the wild-type enzyme. Specifically, we examine the binding modes across two distinct allosteric domains: an H1047R-specific pocket and a pan-mutant cryptic site.Expert opinion: Mutant-selective allosteric inhibitors achieve selectivity by targeting mutant residues or exploiting unique protein conformational dynamics. The rapidly diversifying patent landscape provides broader opportunities for the discovery of superior inhibitors. Furthermore, development of allosteric inhibitor-based PROTACs is discussed as a promising frontier for enhancing therapeutic precision. Ultimately, deeper understanding of evolving resistance mechanisms provides the design principles required to develop next-generation PI3Kα therapeutics capable of overcoming clinical resistance.","PeriodicalId":12314,"journal":{"name":"Expert Opinion on Therapeutic Patents","volume":" ","pages":"865-891"},"PeriodicalIF":4.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148600837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are four RSK family members of which RSK1/2 are tumor promoters whereas RSK3/4 can act as tumor suppressors.Areas covered: The review summarizes patents that have identified compounds that decrease RSK activity. These patents all focus on the use of RSK inhibitors as cancer therapeutics. The patents were identified using the World Intellectual Property Organization, United States Patent and Trademark Office, and Derwent World Patents Index databases.Expert opinion: The compounds disclosed in this patent review do not exhibit isoform specificity and there is limited or no information on selectivity and on target activity. The importance of RSK as a target is demonstrated by transition of the pan-RSK inhibitor, PMD-026, to phase 2 for metastatic breast cancer. RSK isoforms differ in their contributions to transformation. Therefore, specific inhibitors are needed, which is challenging as RSK kinase domains are similar. It is possible that PROTACs for RSK2 and RSK4 can be generated by exploiting their allosteric binding pockets with SL0101 or floxacin antibiotics, respectively.","PeriodicalId":12314,"journal":{"name":"Expert Opinion on Therapeutic Patents","volume":" ","pages":"781-795"},"PeriodicalIF":4.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148600884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particular emphasis is placed on the structural evolution of AZD5305-derived compounds and emerging quinazolinone- and isoquinolinone-based chemotypes. Key design strategies, including adenine-pocket optimization, linker remodeling, conformational restriction, and scaffold diversification, are discussed together with their impact on PARP1 selectivity and biological activity.Expert opinion: Selective PARP1 inhibition has become a major focus of innovation in the PARP field. Current patents indicate that adenine-pocket engagement, linker optimization, conformational control, and scaffold innovation are central to achieving high PARP1 selectivity and represent important directions for future intellectual property development. Despite significant progress, the disclosed chemical space remains relatively limited, highlighting opportunities for further scaffold diversification and differentiated patent strategies.
