The design, synthesis, in vitro and in vivo evaluation of 6-substituted benzimidazole with 1, 4-disubsituted or 1, 5-disubsituted indole derivatives as novel angiotensin II receptor antagonists are outlined. Radioligand binding assays showed that several 6-substituted benzimidazole derivatives displayed high affinities binding to the angiotensin II type 1 receptor at the same order of magnitude to telmisartan. The biological evaluation on spontaneously hypertensive rats showed that 2-[4-[[2-n-propyl-4-methyl-6-(1-methylbenzimidazol-2-yl)benzimidazole-1-yl]methyl]-1H-indol-1-yl]benzoic acid, 1c, could cause significant decrease on MBP in a dose dependent manner. Its maximal response lowered 53 mmHg of MBP at 5 mg/kg and 64 mmHg of MBP at 10 mg/kg after oral administration, and the significant antihypertensive effect lasted beyond 24 h, which was better than both losartan and telmisartan. A study designed to determine acute toxicity showed that 1c had low acute toxicity with no significant changes in the weight and no obvious untoward reactions. The encouraging results make 1c an effective and durable anti-hypertension drug candidate and deserve further investigation for therapeutic application.

A trans diacyloxylation of indoles is accomplished by employing PhI(OAc)2 as the oxidant. A broad range of functional groups are well tolerated. Both the electronic properties of the N-protecting groups of indoles and the acidity of the reaction media play important roles in the selectivity of indole acyloxylation reactions.
