Biological Activity

5-HT1A Receptor |
5-HT1B/D Receptor |
AZD3676 (16 h) exhibits nanomolar affinity for 5-HT1A (Ki = 0.13 nM) and 5-HT1B (Ki = 2.4 nM) receptors in cynomolgus monkey brain homogenates[1].
AZD3676 (0.4-20 μM) shows concentration-dependent plasma protein binding, with species-specific unbound fractions ranging from 0.014 (human) to 0.37 (guinea pig) at the predicted therapeutic maximum concentration of ~1 μM[1].

AZD3676 (1-10 μmol/kg; s.c., p.o.; single dose) significantly reverses Scopolamine(HY-N0296)-induced cognitive impairment in C57BL/6 mice, as demonstrated by restored freezing behavior in a contextual fear conditioning assay[1].
AZD3676 (0.03-3 μmol/kg; s.c.; single dose) dose-dependently occupies 5-HT1ₐ receptors in healthy C57BL/6 mice, with a half-maximum receptor occupancy of 0.05 μmol/kg s.c. in the frontal cortex[1].
AZD3676 (0.1-10 μmol/kg; s.c.; single dose) dose-dependently occupies 5-HT1A receptors in healthy Sprague Dawley rats, with a half-maximum receptor occupancy of 0.17 μmol/kg s.c. in the frontal cortex[1].
AZD3676 (0.3-10 μmol/kg; s.c.; single dose) dose-dependently occupies 5-HT1A and 5-HT1B receptors in healthy Dunkin Hartley guinea pigs, with half-maximum receptor occupancy values of 0.3 μmol/kg s.c. and 1.2 μmol/kg s.c., respectively[1].
AZD3676 (0.16-0.82 μmol/kg; i.v.; maintenance infusion following initial low-dose bolus) dose-dependently occupies 5-HT1A receptors in healthy cynomolgus monkeys, with a Ki,plasma of 84 nM for half-maximum occupancy in the prefrontal cortex[1].
AZD3676 (0.1-1.8 μmol/kg; i.v.; maintenance infusion following initial low-dose bolus) dose-dependently occupies 5-HT1B receptors in healthy cynomolgus monkeys, with a Ki,plasma of 72 nM for half-maximum occupancy in the occipital cortex[1].
