Abstract Renal cell carcinoma (RCC) is the most common malignant tumor of the human kidney. In RCC cell lines, Transglutaminase 2 (TGase 2, E.C. 2.1.2.13), a protein cross-linking enzyme, is considerably over-expressed in comparison to the level of TGase 2 expression in normal kidney. TGase 2 in RCC binds directly to p53 and induces p53 depletion by the process of autophagy, consequently RCC surviving from p53-induced apoptosis. Therefore, hindering RCC growth via inhibition of TGase 2 could be an effective strategy to treat RCC. In order to develop new inhibitors of TGase 2, we designed small molecule inhibitors of TGase 2. Over 250 compounds were synthesized and the biological activity of the compounds was determined by in vitro enzyme assay and cell-based assay. Through our SAR analysis, several compounds are identified as highly potent TGase 2 inhibitors. Series of compounds were selected for ADME/T test and xenograft experiments. As a result, we have found compound DN201782 as a lead compound with in vitro and in vivo efficacy. That could be applied to potential therafeutic agent for treating RCC.Herein, experimental data and xenograft results are presented in detail.
