Structural elaboration of phenylethylamine to spiro[9,10-dihydroanthracene]-9,3'-pyrrolidine (SpAMDA) produces an agent with unexpectedly high affinity (K(i)=4 nM) at 5-HT(2A) receptors. It was shown that SpAMDA acts as a 5-HT(2A) receptor antagonist. The structure and molecular geometry of SpAMDA are not consistent with existing pharmacophore features, and a novel 5-HT(2A) antagonist pharmacophore
苯乙胺对螺[9,10-二氢蒽] -9,3'-吡咯烷(SpAMDA)的结构修饰产生了一种对5-HT(2A)受体具有出乎意料的高亲和力(K(i)= 4 nM)的药剂。结果表明,SpAMDA可以作为5-HT(2A)受体拮抗剂。SpAMDA的结构和分子几何结构与现有的药效团特征不一致,并提出了一种新型的5-HT(2A)拮抗剂药效团模型,用于结合氨基甲基-9,10-二氢蒽类似物。因此,SpAMDA可能是一类新型的5-HT(2A)受体拮抗剂的结构新颖的亲本,它以独特的方式与受体结合,而不同于现有的5-HT(2A)受体拮抗剂的结合拓扑。
