Background

BOS172722 is a novel and selective Monopolar spindle 1 (Mps1) kinase inhibitor identified as a potential anticancer agent.2 Normally, Mps1 supports the proper division of cancer cells, ensuring survival and replication. The key role of Mps1 in the growth of cancer cells renders it an appealing target for cancer treatment, as its inhibition could lead to favorable effects.1 An in vivo study combined BOS172722 with Paclitaxel for the treatment of triple hormone receptor negative breast cancer, and demonstrated promising synergistic effects.2

Mechanism of action

Mps1 is a protein kinase that is expressed in normal proliferating tissues and in certain actively dividing tumors. It acts during mitosis (cell division) and plays a crucial role in the alignment of chromosomes in cancer cells.1,4 Checkpoint activities by Mps1 normally inhibit the advancement of cancer cells from metaphase to anaphase until structural integrity and alignment occur. BOS172722 binds to Mps1, inhibiting its regulatory checkpoint activities.3 This inhibition causes accelerated cell division with increased missegregation errors that ultimately reduce the viability of malignant cells.1,4
