Discovery of ZN-c3, a Highly Potent and Selective Wee1 Inhibitor Undergoing Evaluation in Clinical Trials for the Treatment of Cancer
J Med Chem 2021 Sep 9;64(17):13004-13024.PMID:34423975DOI:10.1021/acs.jmedchem.1c01121.
Wee1 inhibition has received great attention in the past decade as a promising therapy for cancer treatment. Therefore, a potent and selective Wee1 inhibitor is highly desirable. Our efforts to make safer and more efficacious Wee1 inhibitors led to the discovery of compound 16, a highly selective Wee1 inhibitor with balanced potency, ADME, and pharmacokinetic properties. The chiral ethyl moiety of compound 16 provided an unexpected improvement of Wee1 potency. Compound 16, known as ZN-c3, showed excellent in vivo efficacy and is currently being evaluated in phase 2 clinical trials.
Inhibitors of cell cycle checkpoint target Wee1 kinase - a patent review (2003-2022)
Expert Opin Ther Pat 2022 Dec;32(12):1217-1244.PMID:36620912DOI:10.1080/13543776.2022.2166827.
Introduction: DNA damage repair in most malignancies with mutation of p53 is more dependent on the G2/M checkpoint. Wee1 kinase is a key regulator of the G2/M checkpoint. If Wee1 is inhibited, it results in cells with unrepaired DNA damage entering mitosis prematurely, leading to mitotic catastrophe and subsequent cell death via the apoptotic program. Therefore, inhibition of Wee1 kinase which overexpressed in several cancer cell lines has emerged as a promising therapy for cancer treatment. Areas covered: This review summarizes for the first time the structures of small-molecule inhibitors of Wee1 reported in patents published from 2003 to 2022 and the recent clinical developments. It also provides perspectives on the challenges and the future directions. We used different methods to search different databases (PubMed, Reaxys, clinicaltrials.gov)for the literature we needed. Expert opinion: Although the small-molecule inhibitors of Wee1, Adavosertib, and ZN-c3 have entered the clinical phase II, the clinical toxicity exhibited by Adavosertib remains the subject of greater concern. The use of Wee1 inhibitors as monotherapy or in combination therapy remains the main trend in Wee1 inhibitors at present.
Clinical development of WEE1 inhibitors in gynecological cancers: A systematic review
Cancer Treat Rev 2023 Apr;115:102531.PMID:36893690DOI:10.1016/j.ctrv.2023.102531.
Introduction: The anti-tumor activity of WEE1 inhibitors (WEE1i) in gynecological malignancies has recently been demonstrated in clinical trials and its rationale is based on biological/molecular features of gynecological cancers. With this systematic review, we aim to outline the clinical development and current evidence regarding the efficacy and safety of these targeted agents in in this patient group. Methods: Systematic literature review of trials including patients with gynecological cancers treated with a WEE1i. The primary objective was to summarize the efficacy of WEE1i in gynecological malignancies regarding objective response rate (ORR), clinical benefit rate (CBR), overall survival (OS) and progression-free survival (PFS). Secondary objectives included toxicity profile, Maximum Tolerated Dose (MTD), pharmacokinetics, drug-drug interactions and exploratory objectives such as biomarkers for response. Results: 26 records were included for data extraction. Almost all trials used the first-in-class WEE1i adavosertib; one conference abstract reported about ZN-c3. The majority of the trials included diverse solid tumors (n = 16). Six records reported efficacy results of WEE1i in gynecological malignancies (n = 6). Objective response rates of adavosertib monotherapy or in combination with chemotherapy ranged between 23% and 43% in these trials. Median PFS ranged from 3.0 to 9.9 months. The most common adverse events were bone marrow suppression, gastrointestinal toxicities and fatigue. Mainly alterations in cell cycle regulator genes TP53 and CCNE1 were potential predictors of response. Conclusion: This report summarizes encouraging clinical development of WEE1i in gynecological cancers and considers its application in future studies. Biomarker-driven patient selection might be essential to increase the response rates.
