Abstract

In this study, we discovered and identified a novel AXL/triple angiokinase inhibitor 11b by rational structural modification based on the structure of triple angiokinase inhibitor Nintedanib. We found that 11b potently inhibited AXL expression with the IC₅₀ value of 3.75 nM and possessed similar inhibitory activity on KDR as Nintedanib. In the assay of antiproliferative activity on NIH/3T3, HUVEC, Bxpc-3, and MDA-MB-231, 11b showed better inhibitory ability than Nintedanib. In pancreatic cancer xenograft mouse models from Bxpc-3 cells, even when the dosage was halved, 11b exhibited better or comparable effects to Nintedanib (tumor growth inhibition (TGI) based on tumor volume change during the trial or tumor weight). Notably, we also found that 11b prohibited Bxpc-3 resulted lung metastasis by inhibiting its epithelial–mesenchymal transition (EMT) process. Another mechanism assay also proved that 11b inhibited the function of blood vessels and fibroblasts, promoted apoptosis of cancer and fibroblast cells, and exhibited low toxicity and good metabolic stability.

期刊介绍： The Journal of Medicinal Chemistry is a prestigious biweekly peer-reviewed publication that focuses on the multifaceted field of medicinal chemistry. Since its inception in 1959 as the Journal of Medicinal and Pharmaceutical Chemistry, it has evolved to become a cornerstone in the dissemination of research findings related to the design, synthesis, and development of therapeutic agents. The Journal of Medicinal Chemistry is recognized for its significant impact in the scientific community, as evidenced by its 2022 impact factor of 7.3. This metric reflects the journal's influence and the importance of its content in shaping the future of drug discovery and development. The journal serves as a vital resource for chemists, pharmacologists, and other researchers interested in the molecular mechanisms of drug action and the optimization of therapeutic compounds.
