3,5-Bis(aminopyrimidinyl)indole, Pim kinase, Inhibitor
Pim kinases are promising targets in the treatment of hematopoietic and solid cancers. Meridianin C was chosen as a starting point to discover novel pim kinase inhibitors. Using known pim kinase’s structural information, aminopyrimidine was introduced to provide the hydrogen-bonding interactions with the conserved lysine residue in the ATP binding pocket of all three Pim kinases. Synthesized 3,5-bis(aminopyrimidinyl)indole derivatives showed pan-pim inhibitory activity. Aminoalkyl substituent was attached on the aminopyrimidine to further enhance the potency and physicochemical properties of compound. The research reveals a significative way of designing compounds with high potency and kinase selectivity for pan-pim kinases.
