Angiotensin II human (Angiotensin II) acetate is a vasoconstrictor and a major bioactive peptide of the renin/angiotensin system. Angiotensin II human acetate plays a central role in regulating human blood pressure, which is mainly mediated by interactions between Angiotensin II and the G-protein-coupled receptors (GPCRs) Angiotensin II type 1 receptor (AT1R) and Angiotensin II type 2 receptor (AT2R). Angiotensin II human acetate stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human acetate induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human acetate also induces apoptosis. Angiotensin II human acetate induces capillary formation from endothelial cells via the LOX-1 dependent redox-sensitive pathway.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
