摘要:
Lysine specific demethylase 1 plays a crucial role in regulating histone methylation at residues K4 and K9 on histone H3 and over-expresses in a variety of cancers. Here we designed, synthesized and evaluated a series of N-(3-substituted-phenyl)benzenesulfonamides as reversible lysine specific demethylase 1 inhibitors. All the compounds exhibited lysine specific demethylase 1 inhibition with the half maximal inhibitory concentration (IC50) values between 7.5 and 68 mu M. Three most active compounds 2a, 2c and 2i displayed only modest effect on flavin adenine dinucleotide-dependent enzymes mono-amine oxidases A and B, and their reversibilities of lysine specific demethylase 1 inhibition were confirmed. Molecular docking was also carried out to predict the binding mode of 2a into the active site of lysine specific demethylase 1. Taken together, N-(3-substituted-phenyl)benzenesulfonamides including 2a represent a new class of selective and reversible lysine specific demethylase 1 inhibitors with pharmaceutical research.
