GPNA hydrochloride is a well known substrate of the enzyme γ-glutamyltransferase (GGT). GPNA hydrochloride is a specific glutamine (Gln) transporter ASCT2 inhibitor. GPNA hydrochloride also inhibit Na+-dependent carriers, such as SNAT family (SNAT1/2/4/5), and the Na+-independent leucine transporters LAT1/2. GPNA reversibly induces apoptosis in A549 cells.
