Webb15 juni 2024 · 3. Results3.1. Binding affinity of (+)PHNO to membranes from different cell lines transfected with several amine receptors. Inhibition isotherms confirmed that (+)PHNO is a high affinity ligand for the dopamine hD 3 receptor with a pK i of 10.1 and about 100 times lower affinity for the hD 2L and hD 2S receptors (pK i = 8.02 and 7.92, … Webb1 juni 2016 · An electrochemically generated redox couple (PhNHOH/PhNO) exhibits reversible voltammetric response at ∼−0.06 V with a surface coverage of (7.19 ± 0.26) × 10 −9 mol cm −2. The redox couple efficiently mediates the oxidation of NADH at 0.04 V, which is ∼600 mV less positive potential than the unmodified electrode. diary\u0027s 50

WebbA technique for preparing and handling stable solutions of the nitrobenzene radical-anion, (PhNo 2 ·) –, in dry methyl cyanide is described. The first-order decay of this radical in the presence of a small percentage of an aqueous buffer is ascribed to the diffusion-controlled rate of neutralisation of the anion.
