Identification of inhibitors of nitric oxide synthase that do not interact with the endothelial celll‐arginine transporter

porcine aortic endothelial cells cultured in microwell plates or perfused in microcarrier columns

Nitric oxide (NO) synthase inhibitors (NG-monomethyl-L-arginine, NG-iminoethyl-L-ornithine, NG-nitro-L-arginine, NG-nitro-L-arginine methyl-ester) and other cationic amino acids (L-Homoarginine, L-lysine, L-ornithine)
