synthesis and antihypertensive activity of novel 4-[1-(4-x-benzyl)-5-imidazolyl] dihydropyridines in rat
نویسندگان
چکیده
a series of 1,4-dihydropyridine calcium channel blockers bearing 1-(4-x -benzyl)-5-imidazolyl substituent at 4 position (5a-e) (x=h, f) were synthesized and tested for antihypertensive activity in desoxycorticosterone acetate (doca)-induced hypertension in rats. amlodipine was used as the standard dihydropyridine. all compounds tested showed lower antihypertensive activity than that of amlodipine. the most active compound (5e) had fluorine substituent (x=f).

The o-nitrophenyl group at position 4 of dihydropyridine of nifedipine analogues was replaced with 2-alkylthio-1-benzyl-5-imidazolyl substituent. Starting from dihydroxyacetone 2-alkythio-1-benzyl- 5-formyl imidazole (3) was first synthesized which was subsequently used in synthesizing symmetrical (5a-f) and asymmetrical (6a,b) dihydropyridines. Primarily pharmacological studies of the title co...

Objectives In order to provide a pharmacological profile for some newly synthesized dihydropyridines, we investigated their effects on the isolated rat colon segments and the isolated rat atrium contractility. The tested compounds include alkyl ester analogues of nifedipine, in which the ortho-nitrophenyl group at position 4 is replaced by 2-alkylthio-1-benzyl-5-imidazolyl substituent, and nif...
