The dependencies of the rates of NN decay (○) and IN formation (□) on concentration of PAPA NONOate (A) and AS (B) measured by EPR using 0.5 mM cPTIO/0.5 mM hcPTI (filled symbols) or 0.5 mM NN+/5 mM hIN+ (empty symbols). Lines represent linear approximations yielding half lifetime of PAPA NONOate and AS decomposition τ1/2 = (88±2) min and τ1/2 = (14.0±0.2) min, correspondingly. The stoichiometry values Δ[IN]/Δ[NN] were found to be equal to 1.9±0.1 (A) and 0.95±0.07 (B).
