| Bioactivity | AZD7325 is a potent and orally active partial selective PAM of GABAAα2 and Aα3 receptor (Ki=0.3 and 1.3 nM, respectively), and has less antagonistic efficacy at the Aα1 and Aα5 receptor subtypes[1][4]. AZD7325 is a moderate CYP1A2 and a potent CYP3A4 inducer in vitro[2]. AZD7325 has the potential for the investigation of anxiety and dravet syndrome[3]. PAM: positive allosteric modulator. | ||||||||||||
| Invitro | AZD7325 is a high affinity and selective modulator of the GABAA receptor system, exhibits high binding affinity at GABAAα1, α2 and α3 (Ki=0.5, 0.3, and 1.3 nM, respectively), and low at GABAAα5 (Ki=230 nM)[4].AZD7325 (0-10 µM; 3 consecutive days; once daily) causes a maximal CYP1A2 mRNA expression of 3.2-fold, 2.1-fold, and 2.5-fold in human hepatocytes from donor HH210, HH215, and HH216, respectively[2].AZD7325 (0-10 µM; 3 consecutive days; once daily) causes CYP1A2 and CYP3A4 protein expression in human hepatocytes from donor HH210[2].

| In Vivo | AZD7325 (oral administration; 10, 17.8 or 31.6 mg/kg; 30 minutes before the induction of hyperthermia) attenuates hyperthermia-induced seizures, shows median thresholds in the treatment groups of 42.8°C for 10 mg/kg, 43.3°C for 17.8 mg/kg, and 43.4°C for 31.6 mg/kg compares to 42.2°C in vehicle group[3].
