The antihypertensive activity of nitrendipine analogues can be improved by properly lengthening its alkyl chain in 3- or 5-position. Nitrendipine and its seven analogues were synthesized, and their antihypertensive activities in spontaneously hypertensive rats (SHR) were evaluated by ig administration. It was found that 5-n-heptyl 3-methyl 2,6-dimethyl-4-(3-nitrophenyl)-1,4- dihydropyridine- 3,5-dicarboxylate [(±)-5] exhibited the strongest antihypertensive effect amongst eight compounds. (?)-5-nheptyl 3-methyl 2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine- 3,5-dicarboxylate [(+)-5] was also prepared. Antihypertensive activities of (±)-5 and (?)-5 in SHR were compared. The results showed that (±)-5 and (?)-5 had a higher potency than nitrendipine, and (+)-isomer was 1.79-fold the raceme at a dose of 2 mg/kg. Springer Science+Business Media, LLC 2010.
