Conformationally restricted benzamide bioisosteres were investigated when the chiral phenyldihydroimidazole derivative 4e (FAUC 179) showed strong and highly selective dopamine D4 receptor binding (K(i)high=0.95nM). Mitogenesis experiments indicated partial agonist properties (42%). EPC syntheses of the target compounds of type 4 were performed starting from alpha-amino acids.
当手性苯基二氢咪唑衍生物4e(FAUC 179)表现出强而高度选择性的多巴胺D4受体结合(K(i)high = 0.95nM)时,研究了构象受限的苯甲酰胺生物异构体。有丝分裂实验表明部分激动剂性质(42%)。从α-氨基酸开始进行类型4的目标化合物的EPC合成。
