Abstract
Introduction: Kelch-like ECH-associated protein 1 (Keap1), an E3 ligase negatively regulating the nuclear factor erythroid 2-related factor 2 (Nrf2), has emerged as an auspicious drug target for treating ailments associated with oxidative stress and inflammation. Discovery of Keap1 inhibitors have attracted significant interest.
Areas covered: This review covers patents on Keap1 inhibitors from 2019 to 2024, providing a comprehensive analysis of their structural characteristics, optimization strategies, pharmacological properties and clinical progress.
Expert opinion: Extensive efforts have been devoted to enhance potency and drug-like properties of Keap1 inhibitors. Strategies such as ROS-cleavable prodrug design, bivalent inhibition and PROTACs are emerging. As the range of drug types and applications expands, Keap1 inhibitors are becoming a sagacious option for disease treating.
期刊介绍：
Expert Opinion on Therapeutic Patents (ISSN 1354-3776 [print], 1744-7674 [electronic]) is a MEDLINE-indexed, peer-reviewed, international journal publishing review articles on recent pharmaceutical patent claims, providing expert opinion the scope for future development, in the context of the scientific literature.
The Editors welcome:
Reviews covering recent patent claims on compounds or applications with therapeutic potential, including biotherapeutics and small-molecule agents with specific molecular targets; and patenting trends in a particular therapeutic area
Patent Evaluations examining the aims and chemical and biological claims of individual patents
Perspectives on issues relating to intellectual property
The audience consists of scientists, managers and decision-makers in the pharmaceutical industry and others closely involved in R&D
