Synthesis and properties of 4-substituted-1-piperazinyl-propyl derivatives of 1-phenyl-7-methylpyrimido-[4,5-d]pyrimidin-4-one.
In reactions of 1-phenyl-7-methyl-4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimido[ 4,5-d]pyrimidin e (1) with 1-(3-chloropropyl)-4-methyl(phenyl, 3-chlorophenyl, 2-pyrimidynyl, 2-thiazolyl)piperazines (5), mixtures of isomeric N- and S-substituted derivatives of compound 1 (3 and 4) were obtained. Isomers were separated by fractional crystallization. The structure of novel compounds 3 and 4 was confirmed by elemental and spectral analyses. In pharmacological screening compounds 3b and 4b displayed rather strong analgesic action, inhibited amphetamine hyperactivity and abolished apomorphine stereotypy. Compounds 3e,3d and 4e attenuated m-chlorophenylpiperazine-induced hypothermia.
