H-D-Phe-Pip-Arg-pNA (S-2238) dihydrochloride, a chromogenic substrate, is patterned after the N-terminal portion of the A alpha chain of fibrinogen, which is the natural substrate of thrombin. H-D-Phe-Pip-Arg-pNA dihydrochloride is specific for thrombin and is used to measure antithrombin-heparin cofactor (AT-III). The AT-III assay using H-D-Phe-Pip-Arg-pNA dihydrochloride is sensitive, accurate, and easy to perform.

Angiotensin II is a potent direct vasoconstrictor, causing arteries and veins to constrict, so leading to an increase in blood pressure.

ELOVL1-IN-3 is a potent and orally active inhibitor of elongation of very long chain fatty acid 1 (ELOVL1) enzyme. ELOVL1-IN-3 serves as a useful tool for researching adrenoleukodystrophy (ALD).
