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 μM agitating on MT1 and MT2 receptors, respectively. Additionally, we carried out in vivo experiments
抑郁症与全世界高死亡率和高发病率有关。通过我们的随机筛选,首先揭示了合成了23种厚朴酚衍生物,然后在体内和体外评估了它们的抗抑郁潜力。发现化合物7c是最有前途的化合物,在MT 1和MT 2受体上的EC 50值分别为396.5和383.0μM 。此外,我们进行了体内实验以确认化合物7c的功效和安全性。; 该化合物被发现具有口服生物利用度并且非常有效,从而导致抑郁症小鼠模型(强迫游泳试验和尾巴悬吊试验)的固定时间大大减少;通过确定其对不同小鼠大脑区域中单胺神经递质及其代谢产物水平的影响,探索其作用机制。急性毒性研究表明,7c的50%致死剂量(LD50)高于2000 mg / kg,口服总共鉴定出25种7c代谢物,包括I期5种代谢物和II期20种代谢物。总而言之,这些结果表明厚朴酚衍生物7c是用于开发新的化学类抗抑郁药的有前途的先导化合物。
