Product Description

Cell permeable, hydroxylated metabolite of HA-1077 . 2HCl (Fasudil) (Prod. No. ALX-270-071) that displays anti-anginal properties. Acts as an ATP-competitive and reversible inhibitor of Rho kinase (ROCK) with ~100-fold greater selectivity over MLCK, MRCKβ and PKC. Inhibits coronary arteriosclerotic lesion formation. Increases osteocalcin expression and has beneficial effects on pulmonary hypertension.
