5-Butyl­amino-2-2-(dimethyl­amino)eth­yl-1H-benzdeisoquinoline-13(2H)-dione

摘要

The title compound, C20H25N3O2, is a new amonafide analogue, which exhibits anti­tumor activity. The asymmetric unit contains two mol­ecules with similar conformations for the substituted aliphatic chains. The two independent mol­ecules form dmers through N—H⋯N hydrogen bonds. The crystal structure is stabilized via π–π stacking inter­actions, the shortest centroid–centroid separation between six-membered rings being 3.673 (2) Å.
