Design, Synthesis, and Biological Evaluation of New Diaminoquinazolines as β-Catenin/Tcf4 Pathway Inhibitors
摘要:
More than 50 new diaminoquinazoline derivatives have been synthesized and evaluated in a colon carcinoma cell growth inhibition assay using HCT116 and SW480 cells. Twenty compounds with good cell growth inhibitory activities (<4 mu M) were tested as inhibitors of the beta-catenin/T cell transcription factor 4 (Tcf4) signaling pathway using a HCT116 cell-based luciferase reporter assay. Results from the biological activities as well as the comparative molecular field analysis (CoMFA) of the properties of the molecules yielded a preliminary structure-activity relationship (SAR). Three potent compounds, 74, 78, and 86, showed IC50 values <1 mu M for growth inhibition of HCT116 cells and similar to 1 mu M for SW480 cells, as well as IC50 values of 1.5-2.5 mu M for HCT116 cells with the luciferase reporter assay.

We are introducing a novel series of 2,4-diaminoquinazolines as beta-catenin/Tcf4 inhibitors which were identified by ligand-based design. Here we elucidate the SAR of this series and explain how we were able to improve key Molecular properties such as Solubility and cLogP leading to compound 9. Analogue 9 exhibited better biological activity and improved physical and pharmacological properties relative to the HTS hit 49. Furthermore, 9 demonstrated good cell growth inhibition against several human colorectal cancer lines such as LoVo and HT29. In addition, treatment with compound 9 led to gene expression changes that overlapped significantly with the transcriptional profile resulting from the pathway inhibition by siRNA knockdown of beta-catenin or Tcf4. Subsequently, 9 was tested for efficacy in a beta-catenin/RKE-mouse xenograft, where it led to more then 50% decrease in tumor Volume.
