The present invention relates to compounds of formula (I)
and pharmaceutically acceptable salts and solvates thereof, wherein the substituents are as defined herein, compositions containing such compounds and the uses of such compounds for the treatment of various diseases and conditions such as asthma.
Some new 5-bromo-2,4-dichloro-6-alkylpyrimidines were prepared by sequential treatment of 6-alkyl-pyrimidin-2,4(1 H ,3 H )-diones with bromine and phosphoryl chloride. Condensation of the dithizone with 5-bromo-2,4-dichloro-6-alkylpyrimidines in alkaline acetonitrile achieved 5-alkyl-7-chloro-3-phenylazo-1-phenyl- 1H -pyrimido[4,5- e ][1,3,4] thiadiazines. 7-chlorine atom of these compounds was replaced
The present invention aims to provide a compound having superior pharmacological action, physicochemical properties and the like, which is useful for the prophylaxis or treatment s of circulatory diseases such as hypertension, cardiac diseases, arteriosclerosis, renal diseases, cerebral apoplexy and the like and/or metabolic diseases such as hyperlipidemia, obesity, diabetes and the like, central nervous disorders such as cerebral infarction and the like, mental diseases such as dementia, depression and the like, and the like.
A compound represented by the formula (I):
wherein each symbol is as defined in the specification, or a salt thereof.
