Collectively, our results demonstrate the potency of exatecan as a TOP1 inhibitor and its clinical potential in combination with ATR inhibitors, using SLFN11 and HRD as predictive biomarkers. The combination of CBX-12 with ceralasertib significantly suppressed tumor growth in mouse xenografts. ![]() ![]() To establish the translational potential of this combination, we tested CBX-12, a clinically developed pH-sensitive peptide–exatecan conjugate that selectively targets cancer cells and is currently in clinical trials. Violin Plots for data distribution visualization. How To Perform A One-Way ANOVA In GraphPad Prism 53,686 views 480 Dislike Share Top Tip Bio 36. We also show that exatecan kills cancer cells synergistically with the clinical ATR inhibitor ceralasertib (AZD6738). Nested Data Table for Nested t test and Nested One-way ANOVA (Mixed Effects Model). We demonstrate the value of SLFN11 expression and homologous recombination (HR) deficiency (HRD) as predictive biomarkers of response to exatecan. How to Perform a One-way ANOVA in Prism Essential Statistics This video walks you through the steps required to perform a one-way ANOVA, including what analysis choices and options you will have to make about your experiment to perform the analysis. In this guide, I will explain how to perform an unpaired (independent) T-test in GraphPad Prism. Accordingly, exatecan showed much stronger TOP1 trapping, higher DNA damage, and apoptotic cell death than the classical TOP1 inhibitors used clinically. How To Perform An Unparied T-Test In GraphPad Prism. ![]() Modeling exatecan binding at the interface of a TOP1 cleavage complex suggests two novel molecular interactions with the flanking DNA base and the TOP1 residue N352, in addition to the three known interactions of camptothecins with the TOP1 residues R364, D533, and N722. Here, we report the molecular pharmacology of exatecan compared with the clinically approved topoisomerase I (TOP1) inhibitors and preclinical models for validating biomarkers and the combination of exatecan with ataxia telangiectasia and Rad3-related kinase (ATR) inhibitors. ![]() Exatecan and deruxtecan are antineoplastic camptothecin derivatives in development as tumor-targeted-delivery warheads in various formulations including peptides, liposomes, polyethylene glycol nanoparticles, and antibody–drug conjugates.
