Product Description

This kit contains four nitric oxide synthase (NOS) inhibitors: 7-NI (00240) (50 mg), L-NMMA (00241) (25 mg), L-NIL (00242) (5 mg) and L-NIO (00243) (5 mg).

7-NI is a selective inhibitor for the brain nitric oxide synthase (NOS).

  • Yellow orange solid soluble in DMSO
  • Store desiccated at 4°C
  • C7H5N3O2
  • MW: 163.1
  • [2942-42-9]

L-NMMA (NG-Methyl-L-arginine, acetate salt) competitively inhibits nitric oxide synthase in a wide range of cells.

  • White solid soluble in water
  • Store desiccated at 4°C
  • C9H20N4O4
  • MW: 248.3
  • [53308-83-1]

L-NIL (N6-(1-Iminoethyl)-lysine, hydrochloride) is a potent and selective inhibitor of nitric oxide synthase that exhibits about 28-fold greater selectivity for inducible nitric oxide synthase (IC50 = 3.3 uM) than for the rat brain constitutive enzyme (IC50 = 92 uM). It exhibits about 10-fold greater inhibitory potency than NG-monomethyl-L-arginine in inhibiting γ-interferon-induced NO2– production (IC50 = 460 nM).

  • White solid soluble in water
  • Store at 4°C
  • C8H19Cl2N3O2
  • MW: 260.2
  • [150403-89-7]

L-NIO (N5-(1-Iminoethyl)-L-ornithine, dihydrochloride) is a potent, irreversible inhibitor of neutrophil nitric oxide synthase.

  • White solid soluble in water
  • Store desiccated at -20°C
  • C7H17Cl2N3O2
  • MW: 246.1
  • [36889-13-1]
