The enantiomers of two analogs of Sazetidine-A as well as several other novel biosteric analogues were synthesized. Their binding affinities at three major nAChRs subtypes and selectivity profiles were determined. Though many (S)-enantiomers of Sazetidine-A analogs have high binding affinities and good subtype selectivities, it is not a general rule that (S)-enantiomers are better than their (R) counterparts
合成了Sazetidine-A的两个类似物的对映体以及其他几种新颖的生物立体类似物。确定了它们在三种主要nAChRs亚型的结合亲和力和选择性谱。尽管Sazetidine-A类似物的许多(S)-对映异构体具有高结合亲和力和良好的亚型选择性,但是(S)-对映异构体优于其(R)对映异构体并不是普遍的规律。乙炔基被其生物等位基因三唑通过点击化学取代的化合物11对α4β2亚型具有较高的结合亲和力(K i = 1.3 nM),对α4β2亚型的选择性比对三氮杂with嗪的α4β2更好。 -一种。叠氮化物15,一种潜在的光亲和标记,显示出更高的选择性和与Sazetidine-A相似的结合特性。与Sazetidine-A相比,联芳基类似物17表现出低得多的亲和力,表明“长尾”侧链对于α4β2nAChR结合的重要性。
