Abstract

Globally, colorectal cancer (CRC) is the third most common type of cancer, and its treatment frequently includes the utilization of drugs based on antibodies and small molecules. The development of CRC has been linked to various signaling pathways, with the Wnt/b-catenin pathway identified as a key target for intervention. Objectives: We have explored the impact of imidazopyridine-tethered chalcone-C (CHL-C) in CRC models. Methods: To determine the influence of CHL-C on apoptosis and autophagy, Western blot analysis, annexin V assay, cell cycle analysis, acridine orange staining, and immunocytochemistry were performed. Next, the activation of the Wnt/(3-catenin signaling pathway and the anti-cancer effects of CHL-C in vivo were examined in an orthotopic HCT-116 mouse model. Results: We describe the synthesis and biological assessment of the CHL series as inhibitors of the viability of HCT-116, SW480, HT-29, HCT-15, and SNU-C2A CRC cell lines. Further biological evaluations showed that CHL-C induced apoptosis and autophagy in down-regulated (3-catenin, Wnt3a, FZD-1, Axin-1, and p-GSK-3(3 (Ser9), and up-regulated p-GSK3(3 (Tyr216) and (3-TrCP. In-depth analysis using structure-based bioinformatics showed that CHL-C strongly binds to (3-catenin, with a binding affinity comparable to that of ICG-001, a well-known (3-catenin inhibitor. Additionally, our in vivo research showed that CHL-C markedly inhibited tumor growth and triggered the activation of both apoptosis and autophagy in tumor tissues. Conclusion: CHL-C is capable of inducing apoptosis and autophagy by influencing the Wnt/(3-catenin signaling pathway. (c) 2024 The Authors. Published by Elsevier B.V. on behalf of Cairo University.
