Computational studies based on the similarity of molecular electrostatic potential maps initiated the synthesis of the tricyclic target compounds 1 (FAUC 725) and 2. Receptor binding studies at the dopamine receptor subtypes D1, D2(long), D2(short), D3 and D4 showed that the azaindole 1 revealed D3 affinity (K(i)=0.54 nM) comparable to the lead pramipexole and enhanced selectivity over D2 and D4.

基于分子静电势图相似性的计算研究启动了三环目标化合物1(FAUC 725)和2的合成。针对多巴胺受体亚型D1,D2(长),D2(短),D3和D4的受体结合研究结果表明,氮杂吲哚1的D3亲和力(K(i)= 0.54 nM)与普拉克索铅相似,并且选择性比D2和D4高。有丝分裂发生实验表明D3选择性二丙胺1的实质内在活性。基于(S)-3-PPP的结构,导致测试化合物2的生物等位取代和构象限制无效。
