The invention relates to pyrimidine derivatives and their pharmaceutically acceptable salts which are useful in the treatment of cerebrovascular diseases, to processes for preparation thereof and to the composition containing the same, said pyrimidine derivatives being represented by the following formula: ##STR1## wherein Ar, R.sup.1, R.sup.2 and R.sup.3 are as defined in the disclosure.
Novel 4-arylpyrimidine derivatives were synthesized by the oxidation of 4-aryl-1, 4-dyhydropyrimidines, and their effects on anti-anoxic (AA) activity in mice and anti-lipid peroxidation (ALP) activity in rat mitochondria were investigated. Among these compounds, ethyl 6-methyl-2-phenyl-4-(4-pyridyl)-5-pyrimidinecarboxylate (4b) has AA activity (10mg/kg, i.p.) and ethyl 6-methyl-4-(3-nitrophenyl)-2-phenyl-5-pyrimidinecarboxylate (4f) has ALP activity (73% inhibition at 10<-5>g/ml). The latter compound (100mg/kg, i.p.) was also effective on arachidonate-induced cerebral edema in rats with comparable potency to that of vitamin E.
