FK866-NAMPT complex (PDB code: 2GVJ) with replacing the boron atom type by the C3 atom type of carboranes predicted that the NAMPT inhibitory activity of 2c was improved by the hydrogen bond formation between the carborane amide and H191 of NAMPT. Although dicarborane compounds 38, 50, 51, and 55 were synthesize aiming to two hydrophobic pockets present in the binding pocket of NAMPT, their inhibitory activity
