Background:
NS 1738 (NSC 213859) is a novel positive allosteric modulator of the α7 nAChR, with respect to positive modulation of α7 nAChR (EC50=3.4 μM in oocyte experiments).
NS 1738 acts by increasing the peak amplitude of acetylcholine (ACh)-evoked currents at all concentrations; thus, it increased the maximal efficacy of ACh. Plotting peak current amplitude against the logarithm of the NS 1738 concentration used for preincubation reveals a sigmoidal concentration-response relationship that is well fit by the Hill equation (EC50=3.4 μM). Under similar experimental conditions, NS 1738 shows comparable efficacy and potency at the rat α7 nAChR (EC50=3.9 μM)[1].
To estimate the ability of NS 1738 to permeate the blood-brain barrier, rats are administered 10 mg/kg NS 1738 intraperitoneally. Peak brain concentrations are measured approximately 30 min after injection, and they amount to
