Abstract
Introduction: Abnormal expression of epidermal growth factor receptor (EGFR) contributes to tumor development, especially in non-small cell lung cancer (NSCLC). Although multiple inhibitors have been developed to target diverse EGFR mutations and several have been approved, the inevitable drug resistance and side effect remain a challenge, which motivates novel strategies. Proteolysis-targeting chimeras (PROTACs) have been gaining momentum for their potential as novel therapeutics for human diseases by triggering protein degradation. To date, various potent and specific EGFR PROTACs have been discovered and some of them have entered clinical trials.
Areas covered: This review provides an overview of EGFR degraders in patents from 2016 to 2022. It provides an update of the discovery strategies, chemical structures, and molecular profiling of all available EGFR PROTACs. SciFinder, PubMed, Web of Science, EPO, and CNIPA databases were used for searching the literature and patents for EGFR PROTACs.
Expert opinion: By employing the PROTAC technology, highly potent and selective EGFR degraders based on four generation EGFR inhibitors have been developed, which offer a new strategy to target EGFR mutations and overcome the drug resistance. Despite the satisfactory result in vitro and in vivo studies, their therapeutic value awaits more rigorous preclinical testing and clinical investigation.
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
