Abstract

PURPOSE: Alkylamino-substituted pyrimidopyrimidine derivatives of formula I [ where R5 and R6 are radical of formula 11 (where R3 and R4 are alkyl or form a saturated heterocyclic ring with the attached N together), alkylamino, hydrogen, halogen or mono - or di - substituted amino ]. For example, 2, 4, 6, 8 - tetra (dimehtylamino) pyrumido [5, 4 - d] pyrimidine.
