Colorectal cancer (CRC) is the fourth leading cause of cancer related death worldwide due to high apoptotic resistance and metastatic potential. Because mutations as well as deregulation of CK1 isoforms contribute to tumor development and tumor progression, CK1 has become an interesting drug target. In this study we show that CK1 isoforms are differently expressed in colon tumor cell lines and that growth of these cell lines can be inhibited by CK1-specific inhibitors.

Therefore, research interest in identifying potent CK1-specific inhibitors is still increasing. A previously published potent and selective benzimidazole-derived CK1δ/ε-specific inhibitor compound with significant effects on several tumor cell lines was further modified to difluoro-dioxolo-benzoimidazole derivatives displaying remarkable inhibitory effects and increased intracellular availability.
