Abstract
Abstract A new compound 2-(4-((2-butyl-5-nitro-1H-benzo[d]imidazol-1-yl)methyl)-1H-indol-1-yl) benzamide (1) was designed, synthesized and evaluated as a novel AT1 receptor antagonist. Compound 1 displayed high affinity to AT1 receptor with an IC50 value of 1.65 ± 0.2 nM in radio-ligand binding assays. It had an efficient and long-lasting effect in reducing blood pressure which could last for more than 12 h at the dose of 10 mg/kg in spontaneously hypertensive rats. Acute toxicity tests suggested that compound 1 was safe with the LD50 value of 2519.81 mg/kg. Besides, in vitro and in vivo tests suggested its anti-proliferative and anti-tumor activities, respectively. So compound 1 could be considered as a novel anti-hypertension, anti-tumor candidate and deserved further investigation.
