The synthesis for trans and cis tricyclic bis(dioxopiperazine)s 5 and 6 from pyrazine-2,3-dicarboxamide (7) is described.Stereoselective antimetastatic activity differences for these analogues were observed following pretreatment of B16-F10 melanoma cells in vitro.Activities for these isomers were compared with selected intermediates, and the data are discussed in relation to previous results obtained with cis- and trans-cyclopropane analogues.
