respectively. Functional experiments showed D3 antagonist properties for the paracyclophane derivatives of type 6. To elucidate putative bioactive low-energy conformations, DFT-based studies including the calculation of diagnostic magnetic shielding properties were performed. An 89% increase in volume for the [2.2]paracyclophane moiety compared to that of the monolayered benzofurane of lead compound 3b
对化学多样性空间的探索取决于新型生物等位元素的发现。作为我们对双层芳烃替代物的研究的延续,我们在此报告4和6型[2.2]对环烷衍生的多巴胺D3受体拮抗剂。对于最有希望的带有2-甲氧基苯基取代基的测试化合物6a,采用立体控制的制备方法当对映异构体(R)-6a(FAUC 418)和(S)-6a的平面手性引起D3结合的显着差异时,可以通过K(i)分别为0.19和3.0 nM的值进行分析。功能实验表明,D3对6型对环烷衍生物具有拮抗作用。为阐明推定的生物活性低能构象,进行了基于DFT的研究,包括诊断性磁屏蔽性质的计算。
