通过对 4 种选定的具有抗抑郁活性的含哌嗪化合物进行片段分析和分子修饰,设计了新型 1,4-取代的哌嗪衍生物 5、A 和 B 系列。我们分别合成了 A 系列的 39 种新类似物和 B 系列的 10 种化合物。使用 Neurotransmitter Transporter Uptake Assay Kit 进行针对 DA、NE 和 5-羟色胺神经递质摄取抑制的抗抑郁药筛选。系列 B 中的化合物对 SERT、NET 和 DAT 的再摄取抑制活性比系列 A 中的更高。系列 B 中哌嗪中心中心和末端苯环之间的间隔物长度似乎发挥了作用。活动中的重要作用。

The Schiff's bases 3a-3h were synthesized by reacting substituted/unsubstituted aromatic aldehydes 2a-2h with 1-(2-aminoethyl)-piperazine 1. A series of novel aryl-3-(2-piperazin-1-ylethyl)-1,3-thiazolidin-4-one 4a-4h and 3-chloro-1-2-[4-(chloroacetyl)piperazin-1-yl]ethyl}-4-arylazetidin-2-one 5a-5h were synthesized from the Schiff's bases of 1-(2-aminoethyl)-piperazine 3a-3h. The structures of synthesized compounds were confirmed by analytical (C, H, and N) and spectral (FT-IR, H-1 NMR, C-13 NMR, and Mass) data. The compounds 4a-4h and 5a-5h were screened for antimicrobial activity. The compounds 4a, 4d, 4f, 4g, 5a, 5d, 5f, and 5g exhibited substantially significant antibacterial as well as antifungal activity.
