Discovery of New Inhibitors of Transforming Growth Factor-Beta Type 1 Receptor by Utilizing Docking and Structure-Activity Relationship Analysis.

ABSTRACT: The transforming growth factor-beta (TGF-β) plays an important role in pathological fibrosis and cancer transformation. Therefore, the inhibition of the TGF-β signaling pathway has therapeutic potential in the treatment of cancer. In this study, the binding modes between 47 molecules with a pyrrolotriazine-like backbone structure and transforming growth factor-beta type 1 receptor (TβR1) were simulated by molecular docking using Discovery Studio software, and their structure-activity relationships were analyzed. On the basis of the analysis of the binding modes of ligands in the active site and the structure-activity relationships, 29,254 new compounds were designed for virtual screening. According to the aforementioned analyses and Lipinski's rule of five, five new compounds (CQMU1901-190
