Antihypertensive activity of 6-arylpyrido[2,3-d]pyrimidin-7-amine derivatives
摘要:
A series of 51 6-arylpyrido[2,3-d]pyrimidin-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-methylpyrido[2,3-d]pyrimidin-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.

effect of acylation with a variety of acids on the antihypertensiveactivity of 6-(2,6-dichlorophenyl)pyrido[2,3-d]pyrimidine-7-amine (1) is reported, and structure-activity relationships are discussed. Although several of the compounds show good oral antihypertensiveactivity in the conscious, spontaneously hypertensive rat (SHR), their activity profile appears to differ from 1 in that the onset of
