    • In vitro nitric oxide release assays. (1) Incubation with 18 mM l-cysteine in phosphate buffer (pH 7.4). A solution of the test compound (1 mL of a 0.2 mM solution in 0.1 M phosphate buffer, pH 7.4) was mixed thoroughly with a freshly prepared solution of l-cysteine (1 mL of a 3.6 mM solution in 0.1 M phosphate buffer, pH 7.4), and the mixture was incubated at 37 °C for 1.5 h in the absence of air. After exposure to air for 10 min at 25 °C, an aliquot of the Griess reagent (1 mL) (freshly prepared by mixing equal volumes of 1.0% sulfanilamide and 0.1% N-naphthylethylenediamine dihydrochloride in water) was added to an equal volume (1 mL) of each test compound's incubation solution with mixing. After 10 min had elapsed, absorbance was measured at 540 nm using a Simadzu UV 2100 UV-vis scanning spectrophotometer. Solutions of 0-100 μM sodium nitrite were used to prepare a nitrite absorbance versus concentration curve under the same experimental conditions. The percent nitric oxide released (quantitated as nitrite ion) was calculated (±SEM, n = 3) from the standard nitrite versus concentration curve. (2) Incubation with phosphate buffer (pH 7.4). This assay was performed as described under procedure 1 above except that a solution of the test compound (2 mL of a 2 mM solution in 0.1 M phosphate buffer pH 7.4) was used and no l-cysteine was added.
