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.

A series of novel 2,6-dimethyl-4-aminopyrimidine hydrazones 5 were rationally designed and synthesized as pyruvate dehydrogenase complex E1 (PDHc-E1) inhibitors. Compounds 5 strongly inhibited Escherichia coli (E. coli) PDHc-E1 (IC50 values 0.94–15.80 μM). As revealed by molecular docking, site-directed mutagenesis, enzymatic, and inhibition kinetic analyses, compounds 5 competitively inhibited PDHc-E1
