The relative fraction of the fast phase of luminescence decay for compound 6 (taken as fraction bound) as a function of [iNOSheme]free. An estimate for the dissociation constant of 6 to iNOSheme was obtained by fitting the curve to a single-site binding model (Kd=3.8±1.4 μM), assuming that the saturation value of the fractional fast phase represents a 1:1 complex.
