A patent review of IDH1 inhibitors (2018-present).

Introduction: isocitrate dehydrogenase 1 (IDH1), a key metabolic enzyme in the cytosol, catalyzes the oxidative decarboxylation of isocitrate to produce α-ketoglutarate (α-KG) and NADPH in the TCA cycle. Pan-cancer studies have demonstrated that IDH1 exhibits a higher mutation frequency and is implicated in a broader range of cancer types, indicating its potential as a promising anti-tumor target.

Areas covered: We summarized patents from 2018 to the present that identify novel molecules, compounds, formulations, and methods for inhibiting mIDH1. The literature was retrieved from Web of Science and PubMed. Patent information was obtained via the State Intellectual Property Office's Patent Search and Analysis platform. Clinical data were sourced from the Cortellis Drug Discovery Intelligence database. The date of the most recent search was .

Expert opinion: Due to multiple signaling pathway dysregulations and compensatory pathways in solid tumor, monotherapies targeting mutant IDH1 (mIDH1) often fail to achieve desired therapeutic outcomes. Consequently, the combination of mIDH1 inhibitors with other therapeutic agents can enhance the efficacy of antitumor treatments and mitigate the risk of drug resistance. Moreover, the development of novel dual or multiple inhibitors and functional molecules targeting mIDH1 May represent a more promising approach.
