Saralasin
Based on 1 Customer Validation
Saralasin ([Sar1,Ala8] Angiotensin II) is an octapeptide analog of angiotensin II. Saralasin 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 can be used for the research of renovascular hypertension, renin-dependent (angiotensinogenic) hypertension.

Saralasin (1 nM, 48 or 72 h) inhibits cell growth in 3T3 and SV3T3 cells[1].
Saralasin (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 (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 (1 μM, perfused rat ovary in vitro) inhibits the ovulation rate versus control and reduces prostaglandin E2 and 6-keto-prostaglandin F1α levels[4].
