Novel constrained β-turn dipeptide mimetics, 8-phenyl thiaindolizidinone amino acids 3, have been synthesized stereoselectively and incorporated into Leu-enkephalin peptides as a replacement of dipeptide GlyâPhe to afford four individual isomers of Leu-enkephalin analogues 6.
我们立体选择性地合成了新型受限δ-匝二肽模拟物--8-苯基噻吩多嗪酮氨基酸 3,并将其加入到亮啡肽中作为二肽 GlyâPhe 的替代物,从而得到了四种不同异构体的亮啡肽类似物 6。
