Abstract

Depression is associated with high mortality and morbidity rates worldwide. By our random screening, it was first revealed that 23 magnolol derivatives were synthesized followed by in vitro and in vivo evaluation of their antidepressive potential. Compound 7c was found to be the most promising compound, with EC50 values of 396.5 and 383.0 mu M agitating on MT1 and MT2 receptors, respectively. Additionally, we carried out in vivo experiments to confirm the efficacy and safety of compound 7c; the compound was found to be orally bioavailable and highly effective, leading to a significant reduction of immobility time in a mouse model of depression (forced swimming test and tail suspension test); the acting mechanism was explored by determining its effect on the levels of monoamine neurotransmitters and their metabolites in different mice brain regions; the acute toxicity study showed that the 50% lethal dose (LD50) of 7c was higher than 2000 mg/kg, p. o. A total of 25 metabolites of 7c were identified, including 5 metabolites in phase I and 20 metabolites in phase II. Altogether, these results indicate that magnolol derivative 7c is a promising lead compound for the development of a new chemical class of antidepressant drugs. (C) 2018 Elsevier Masson SAS.
