Descrizione

Descrizione generale

A boronic acid based arginine analog that acts as a selective, slow- binding, reversible, competitive transition state inhibitor of arginase type I and II (K_i = 310 nM for human recombinant type II arginase, pH 7.5). Shown to enhance nitric oxide-dependent relaxation of human penile corpus cavernosum smooth muscle by inhibiting the activity of arginase. Does not inhibit the activity of nitric oxide synthase (NOS) and may serve as a valuable reagent to probe the physiological relationship between arginase and NOS.

A boronic acid-based arginine analog that acts as a slow-binding, competitive transition state inhibitor of arginases I and II (K_i = 310 nM for human recombinant type II arginase, pH 7.5). BEC does not inhibit nitric oxide synthase (NOS). Causes significant enhancement of NO-dependent smooth muscle relaxation in human penile corpus cavernosum tissue.
