A series of analogs of DM235 and MN19, characterized by rings with different size, have been prepared and evaluated for their nootropic activity in the mouse passive-avoidance test. It was found that the optimal ring size for the analogs of DM235, showing endocyclic both amidic groups, is 6 or 7 atoms. For the compounds structurally related to MN19, carrying an exocyclic amide group, the piperidine ring is the moiety which gives the most interesting compounds.

Pyrimido[5,4-d]pyrimidines of the general formula [Figure] which have an inhibitory effect on signal transduction mediated by tyrosine kinases, their use for the treatment of disorders, in particular of oncoses, and their preparation. Exemplary compounds are: 4-[(3-Chloro-4-fluorophenyl)amino]-6-[1-methyl-4-piperidinylamino]pyrimido[5,4-d]pyrimidine, and 4-[(3-Chloro-4-fluorophenyl)amino]-6-[trans-4-dimethyl-aminocycohexylamino]pyrimido[5,4-d]pyrimidine.
