PDB Ligand
Compound class: Synthetic organic
Comment: MC2050 is a poly(ADP-ribose) polymerase (PARP) inhibitor that is selective for PARP1 over PARP2 [1]. As the dihydrochloride salt it is water soluble. MC2050 interacts with both the nicotinamide and adenine ribose binding sites within the enzyme's catalytic domain.
