Carboxy-PTIO, potassium salt reacts with nitric oxide to form carboxy-PTI derivatives which in turn inhibits NOS (nitric oxide synthase). Carboxy-PTIO, potassium salt is a potassium salt shown to be a stable imidazolineoxyl N-oxide radical compound. Studies have indicated that Carboxy-PTIO, potassium salt is a nitric oxide antagonist and as a result, causes concentration-dependent reductions of murine aortic relaxation. Further studies suggest that at concentrations of 300muM or more Carboxy-PTIO, potassium salt actually slightly enhances relaxation elicited by nitrergic nerve stimulation.
