Pyrimidopyrimidine derivatives, processes for producing them, pharmaceutical compositions containing them and their use as anti-allergic agents |
| abstract |
Pyrimidopyrimidine derivatives having the general formula (I):wherein R<sub>1</sub> represents an alkyl group; R<sub>2</sub> represents an alkyl or phenyl group; R<sub>3</sub> represents a hydrogen atom or an alkyl or lower alkylamino group; and R<sub>4</sub> represents a hydrogen atom or an alkyl, halogenated lower alkyl, phenyl, amino or lower alkylamino group; and pharmaceutically acceptable salts thereof have anti-allergic properties. Various processes for preparing these pyrimidopyrimidine derivatives are disclosed. |
