Figure Lengend Snippet: (A) A saturation binding assay was used to derive a Kd of 164.7 nM for fluorescent clicked PiB (4). (B) Dose-response curve showing displacement of fluorescent clicked PiB (4) (at 140 nM) with increasing concentrations (0–100,000 nM) of PiB (2) ( ) and clickable PiB (3) ( ). From these data, binding affinities (Ki) of 678.4 and 264.7 nM were determined for compounds 2 and 3, respectively (summarized in Table 1).

Article Snippet: Binding affinities were derived using the saturation binding one-site specific non-linear regression analysis model of GraphPad Prism 5 (GraphPad Software Inc., California).

Figure Lengend Snippet: A representative saturation curve of OH-BUP formation by baboon hepatic microsomes. The rate of bupropion hydroxylation to OH-BUP was dependent on bupropion concentration and exhibited typical saturation kinetics.

Article Snippet: The V max and apparent K m values were determined using nonlinear regression analysis of the saturation equation (GraphPad Prism 5, Vision 5.01, Graph Pad Software, Inc.).

Figure Lengend Snippet: The representative saturation curve of threohydrobupropion formation by baboon placental microsomes (A) and the effect of chemical inhibitors selective to carbonyl reductases on the formation of threo- and erythrohydrobupropion by baboon placental microsomes (B). The inhibitors of carbonyl reductase are: 4-methylpyrazole (4-MP, 500µM), barbital (BAR, 500µM), flufenamic acid (FLU, 5µM), dicumarol (DIC, 500µM), menadione (MEN, 100µM), and 18β-glycyrrhetinic acid (18β-GA, 0.1µM). The rates of threo-(TB) and erythrohydrobupropion (EB) are expressed as percent of control (absence of inhibitor) and represent the mean ± S.D. of triplicate experiments. ** Statistical significance of p < 0.01 as determined by one-way ANOVA with Tukey’s comparison.
