  • Saralasin ([Sar1,Ala8] Angiotensin II) acetate hydrate is an octapeptide analog of angiotensin II. Saralasin acetate hydrate is a competitive angiotensin II receptor antagonist with a Ki value of 0.32 nM for 74% of the binding sites, and has partial agonist activity as well. Saralasin acetate hydrate can be used for the research of renovascular hypertension, renin-dependent (angiotensinogenic) hypertension[1][3][6].

In Vitro Saralasin acetate hydrate (1 nM, 48 or 72 h) inhibits cell growth in 3T3 and SV3T3 cells[1]. Saralasin acetate hydrate (5 μM, 2h) restores Ito, fast (Fast-Inactivating Transient Outward K+ Current in Mouse Ventricle) and I K, slow (Slow-Inactivating Transient Outward K+ Current in Mouse Ventricl) to control levels in myocytes[2]. Saralasin acetate hydrate (0.1-10 nM, 40 min) inhibits binding of FITC-Ang II to rat liver membrane preparation (used as the source of angiotensin receptors) with a Ki value of 0.32 nM for 74% of the binding sites and 2.7 nM for the remaining binding sites[3]. Saralasin acetate hydrate (1 μM, perfused rat ovary in vitro) inhibits the ovulation rate versus control and reduces prostaglandin E2 and 6-keto-prostaglandin F1α levels[4]. Cell Proliferation Assay[1] Cell Line: 3T3 and SV3T3 cells Concentration: 1 nM Incubation Time: 48 h, 72 h Result: Inhibited cell growth in 3T3 and SV3T3 cells and caused an increase of cellular renin concentration.
In Vivo Saralasin acetate hydrate (intravenous injection, 5-50 μg/kg, a single dose) ameliorates the oxidative stress and tissue injury in cerulein-induced pancreatitis[5]. Saralasin acetate hydrate (subcutaneous injection, 10 and 30 mg/kg, a single dose) increases serum renin activity (SRA) in normal, conscious rats, without markedly altering blood pressure or heart rate[6]. Animal Model: Cerulein-induced acute pancreatitis rats model[5] Dosage: 5, 10, 20, and 50 μg/kg, a single dose. Administration: Intravenous injection Result: Restored the pancreatic morphological characteristics to the control level. Reduced pancreatic injury and suppressed the glutathione depletion induced by cerulean. Animal Model: Male Sprague-Dawley rats[6] Dosage: 10 and 30 mg/kg, a single dose. Administration: Subcutaneous injection Result: Stimulated renin release without altering blood pressure or heart rate at the time of measuring serum renin levels 20 minutes after injection.
