Abstract:	Small cell lung cancer (SCLC) is one the most aggressive tumors with poor survival rate. SCLC patients often present with metastasis at time of diagnosis, excluding surgery as a treatment option. While patients show high response rate to standard chemotherapy such as cisplatin/etoposide, they soon develop drug resistance and disease progression. Therefore, new therapeutic strategies are urgently needed for SCLC. Several characteristics of SCLC such as aggressiveness and drug resistance could attribute to the existence of a cancer stem cell (CSC) subpopulation in SCLC. The SCLC cell line NCI-H446 has been shown to present high degree of stemness and express stem cell markers including CD133, OCT4, MYC and Nestin. Here we develop a pyrimidine-based small molecule BPR6K471 which potently inhibits Aurora kinase activities in enzymatic- and cell- based assays. BPR6K471 efficiently (IC50 = 66 nM) inhibits proliferation of NCI-H446, and reduces the expression of stem-cell markers. In addition, intravenous injection of BPR6K471 inhibits >90 % progression of NCI-H446 in a mouse xenograft model. These results suggest that targeting Aurora kinases may be a potential therapeutic strategy to combat the CSC subpopulation in SCLC.
