OM99-2 Usage And Synthesis

Uses

OM99-2, an eight residue peptidomimetic, tight-binding inhibitor of human brain memapsin 2 with a Ki value of 9.58 nM[1]. OM99-2 is significantly advanced the development of BACE1 inhibitor[2]. OM99-2 has the potential for the research of the Alzheimer's disease[3].
