Paragraph 0390; 0391, (2015/06/16)
The present invention relates to a compound having an URAT1 inhibitory activity, and to an URAT1 inhibitor, a blood uric acid level-reducing agent and a pharmaceutical composition containing the compound. More specifically, the present invention relates to a compound represented by the formula (I): wherein R1 is -Q1-A1 or the like; R2 is a hydrogen atom, a halogen atom, a lower alkyl group or the like; W1, W2, W3 and W4 are each independently a nitrogen atom or a methine group optionally having substituents, or the like; X and Y are each a single bond, an oxygen atom or the like; Z is a hydroxyl group or COOR3 or the like.

A series of 51 6-arylpyridopyrimidin-7-amine derivatives was prepared and evaluated for antihypertensive activity in the conscious spontaneously hypertensive rat.A number of these compounds, notably 6-(2,6-dichlorophenyl)-2-methylpyridopyrimidin-7-amine (36), lowered blood pressure in these rats in a gradual and sustained manner to normotensive levels at oral doses of 10-50 mg/kg.Normalized blood pressure levels could then be maintained by single daily oral doses.The effect of structural variation in the 6-aryl group and in the 2 and 4 positions of the pyridopyrimidine ring on activity is reported and discussed.
