Rational drug design method has been used to generate 4-arylpiperazine carboxamides in an effort to develop safer, more potent and effective monoamine neurotransmitters reuptake inhibitors. Out of twenty-seven synthesized compounds, compound 9 displayed potent monoamine neurotransmitter reuptake inhibitory activity against HEK cells transfected with hSERT or hNET. A Surflex-Dock docking model of 9 was also studied.

Two series of hybrid analogues were designed, synthesized, and evaluated as a novel class of selective ligands for the dopamine D3 receptor. Binding affinities of target compounds were determined (using the method of radioligand binding assay). Compared to comparator agent BP897, compounds 2a and 2c were found to demonstrate a considerable binding affinity and selectivity for D3 receptor, and especially compound 2h was similarly potent and more selective D3R ligand than BP897, a positive reference. Thus, they may provide valuable information for the discovery and development of highly potent dopamine D3 receptor ligands with outstanding selectivity.

In the search for potent dual norepinephrine and dopamine reuptake inhibitors, several substituted arylpiperazine–tetrazoles were designed, synthesized and evaluated for their neurotransmitter reuptake inhibitory activities. Various derivatives exhibited selective and strong neurotransmitter reuptake inhibitory activity. In particular, compounds with a three-carbon linker displayed selective and stronger potency than those with two-carbon and four-carbon linkers. Interestingly, six compounds, 9b, 9c, 9d, 9o, 9q and 9u displayed more effective activity than the standard drug, bupropion. The provided SAR data and potent biological activity can offer useful guidelines for designing dual norepinephrine and dopamine reuptake inhibitors as effective therapeutic agents for treatment of several central nervous system diseases.

Combined blockade of IKr and IKs potassium channels is considered to be a promising therapeutic strategy for arrhythmia. In this study, we designed and synthesized 15 derivatives through modifying the hit compound 7 that was discovered by screening in-house database by whole-patch clamp technique. All of the compounds were evaluated on CHO and HEK 293 cell lines stably expressing hERG (IKr) and hKCNQ1/KCNE1 (IKs) potassium channels, and half of them exhibited improved dual IKr and IKs inhibitory effects compared to the hit compound. Compounds 7a and 7b with potent dual inhibitory activities were selected for further in vivo evaluations. Due to the preferable pharmacological behaviors, compound 7a deserved further optimization as a promising lead compound.
Synthesis and biological evaluation of novel N-[3-(4-phenylpip-erazin-1-yl) -propyl]-carboxamide derivatives

A series of novel N-[3-(4-phenylpiperazin-1-yl)-propyl]-carboxamide derivatives were synthesised and studied for the potential treatment of HIV. These compounds were obtained through the efficient synthetic route that involved microwave assisted synthesis. These new compounds have been characterised by IR,1H NMR, MS and elemental analysis. The cell-cell fusion inhibitory activities of the compounds have also been evaluated.
