In Vivo, NS-6740 (10 mg/kg; s.c.; single dose), at a dose achieving 98% α7 nAChR occupancy, blocks the memory-improving effects of BMS-933043 in the mouse novel object recognition task[3]. NS-6740 (3-10 mg/kg; s.c.; single dose), at doses achieving 89% and 98% α7 nAChR occupancy, does not enhance memory retention in the mouse novel object recognition task[3].
In Vitro, NS-6740 (0.01-100 μM; 30 min) potently inhibits LPS-induced TNF-α release in enriched primary rat microglial cultures, achieving complete inhibition at concentrations of 50 and 100 μM. Co-treatment with a partial α7 nAChR agonist enhances this effect, which is not mediated by regulation of the MAPK pathway[1]. NS-6740 (5 μM; 60 s) induces persistent desensitization of α7 nAChR expressed in Xenopus laevis oocytes, and the desensitized receptors can be activated by the positive allosteric modulator PNU-120596 [2]. NS-6740 acts as an antagonist of the recombinant 5-HT3A receptor expressed in HEK293 cells, with an IC50 value of 4827 nM[3]. NS-6740 binds to native rat α7 nAChR with high affinity, with a Ki value of 2.85 nM[3]. NS-6740 inhibits the activation of recombinant rat α7 nAChRs expressed in HEK293 cells induced by BMS-933043, with an IC50 value of 283 nM for peak current and 255 nM for net charge[3].
