Biological Information

Background Information:

Inducible nitric oxide synthase (iNOS) is a member of a growing family of enzymes that catalyze the conversion of L-arginine to citrulline and nitric oxide. Like other NOS isoforms, iNOS requires NADPH, FAD and terahydrobiopterin. From diabetes to hypertension, cancer to drug addiction, stroke to intestinal motility, memory and learning disorders to septic shock, sunburn to anorexia, male impotence to tuberculosis, there is probably no pathological condition where nitric oxide does not play an important role.

Testing Information

Procedure Summary:

Mouse recombinant iNOS expressed in E. coli cells is used. Test compound and/or vehicle are combined with 1.5 U/ml‡ of enzyme in Tris buffer pH 8.0. The reaction is initiated by addition of 0.1 mM L-Arginine for another 120 minute incubation period. Add Griess reagent and read plate on a spectrophotometer at 545 nm. Compounds are screened at 10 μM.

Substrate:

100 µM L-Arginine

Incubation:

120 min at 37°C

Control Inhibitor:

AMT

Criteria For Significance:

≥ 50 of max stimulation or inhibition

Test Concentration / Dose:
