Background

IC50: AVE 0991 and Ang-(1–7) competitively bind to bovine aortic endothelial cell membranes with IC50 values of 21 ± 35 and 220 ± 280 nM, respectively.Angiotensin-(1–7) (Ang-[1–7]) acts as a crucial component of the renin-angiotensin system which can regulate and maintain the blood pressure by offsetting effects of Ang II, a typical vasoconstrictor in vivo. AVE 0991, a nonpeptide mimic of Ang-(1–7), performs as an agonist of angiotensin-(1-7) receptor. It plays an important role in exploring effects of Ang-(1-7) and evaluating the potential of Ang-(1-7) as a cardiovascular drug. [1]In vitro: AVE 0991 was found to compete with Ang-(1-7) for bovine aortic endothelial cell membrane receptors with an IC50 of 21±35 nM. There was no significant difference in peak concentrations of NO and O2- released from AVE 0991 treated group and Ang-(1-7) treated group. However, the released amount of NO was approximately 5 times higher in AVE 0991 group than that in Ang-(1-7) group. Moreover, AVE 0091 significantly displaced the binding of I-Ang-(1-7) in both Mas-transfected monkey kidney cells (COS) and Mas-transfected Chinese hamster ovary (CHO) cells. [1]In vivo: AVE 0091 at a dosage of 0.58 nmol/g resulted in a significant decrease in urinary volume, together with an increase in urinary osmolality in water-loaded C57BL/6 mice. [2] The antidiuretic effect of AVE was completely offset by the Ang II antagonists, which indicting a high specificity of AVE 0991. Since Ang II induced atherogenesis and ang-(1–7) offset Ang II action, it was proved that AVE 0991 blocked atherogenesis in apolipoprotein E (apoE)-knockout mice model. [3]Clinical trial: So far, no clinical trial has been conducted.
