Investigation of conformationally restricted benzamide bioisosteres led to the chiral phenyltetrahydropyrimidine derivative ent2a (FAUC 312) displaying strong and highly selective dopamine D4 receptor binding (K(i(high))=1.5 nM). Mitogenesis experiments indicated 83% ligand efficacy when compared to the unselective agonist quinpirole. The target compounds of type 2 and 3 were synthesized in enantiopure
构象受限的苯甲酰胺生物等位基因的研究导致手性苯基四氢嘧啶衍生物ent2a(FAUC 312)表现出强而高度选择性的多巴胺D4受体结合(K(i(high))= 1.5 nM)。与非选择性激动剂喹吡罗相比,有丝分裂实验表明配体效力为83%。从天冬酰胺开始以对映纯形式合成2型和3型目标化合物。
