A series of pyrazino[2,1-b]isoquinoline and 6,15-iminoisoquino[3,2-b]-3-benzazocine compounds related to renieramycins, cribrostatin 4, and phthalascidin was synthesized and their in vitro cytotoxic activities were evaluated against three human cancer cell lines. Pyrazino[2,1-b]isoquinolines, 6,15-iminoisoquino[3,2-b]-3-benzazocines, and other more complex octacyclic compounds have been obtained and derived to precursors of iminium ion species. Hydrogenolysis of the lactam function in pentacyclic compounds gave 1-(3-isoquinolyl)isoquinolines. The micromolar cytotoxic activity of representative structures was apparently uninfluenced by the ability to generate intermediates which would permit covalent bonding to DNA.
