TCS PIM-1 1 is a selective inhibitor of Pim-1 with IC50 value of 50 nM [1].
Pim-1 is a proto-oncogene serine/threonine-protein kinase and plays an important role in cell cycle progression, apoptosis, transcriptional activation and more general signal transduction pathways. It has been shown that Pim-1 over-expression is correlated with a variety of human cancers [2].
TCS PIM-1 1 is a potent Pim-1 inhibitor and has a better selectivity to Pim-1 than to Pim-2. It was revealed that TCS PIM-1 1 was the most potent inhibitor of Pim-1 by outlining the crystal structure and it was also shown that TCS PIM-1 1 had better inhibitory activity to Pim-1 compared with Pim-2 [1].
