A series of 4-aryl-4,7-dihydropyrazolo[3,4-b]pyridine-5-carboxylate derivatives I (R = Me, Ph, cyclopentyl; R1 = Me, Et, CHMe2, cyclohexyl, substituted phenethyl, etc.; R2 = 2-O2NC6H4, 3-O2NC6H4, 2-ClC6H4, 2.8-Cl2C6H4, pyridyl; R3 = H, Me, CHMe2, Ph, cycloalkyl, CO2Et, pyridyl, etc.) was prepared and the compounds were tested for Ca-blocking activity in isolated guinea pig portal vein, antihypertensive activity in spontaneously hypertensive rats, and coronary vasodilating effect in isolated guinea pig heart. A number of derivatives had potent antihypertensive and coronary vasodilating activities. The structure-activity relationships of the series indicated that a 3-cyclopentyl or 3-cyclohexyl substituent and a hydrophobic 5-ester moiety with moderate bulkiness were effective for increasing the pharmacol. potencies.
