Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-Methyl-3-(thiophen-2-yl)-1H-pyrazol-5-amine, is researched, Molecular C8H9N3S, CAS is 118430-78-7, about Studies on dihydropyridines. II. Synthesis of 4,7-dihydropyrazolo[3,4-b]pyridines with vasodilating and antihypertensive activities.Recommanded Product: 1-Methyl-3-(thiophen-2-yl)-1H-pyrazol-5-amine.
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.
