Saralasin  (Synonyms: [Sar1,Ala8] Angiotensin II)

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

Ki: 0.32 nM (Angiotensin II receptor)^[3]

Saralasin (1 nM, 48 or 72 h) inhibits cell growth in 3T3 and SV3T3 cells^[1].
Saralasin (5 μM, 2h) restores I_{to, 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 (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 K_i value of 0.32 nM for 74% of the binding sites and 2.7 nM for the remaining binding sites^[3].
Saralasin (1 μM, perfused rat ovary in vitro) inhibits the ovulation rate versus control and reduces prostaglandin E2 and 6-keto-prostaglandin F_1α levels^[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Saralasin (intravenous injection, 5-50 μg/kg, a single dose) ameliorates the oxidative stress and tissue injury in cerulein-induced pancreatitis^[5].
Saralasin (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].
