Baclofen (1) is a potent and selective agonist for bicuculline-insensitive GABA(B) receptors and is used clinically as an antispastic and muscle relaxant agent. In the search for new bioactive chemical entities that bind specifically to GABA(B) receptors, we report here the synthesis of certain baclofen homologues, namely (R,S)-5-amino-3-arylpentanoic acid hydrochlorides (R,S)-1a-h as well as (R,S
Baclofen (1) 是荷包牡丹碱不敏感 GABA(B) 受体的强效选择性激动剂,临床上用作抗痉挛剂和肌肉松弛剂。在寻找与 GABA(B) 受体特异性结合的新生物活性化学实体时,我们在此报告了某些巴氯芬同系物的合成,即 (R,S)-5-amino-3-arylpentanoic acid hydrochlorides (R,S)- 1a-h 以及 (R,S)-5-amino-3-methylpentanoic 酸 [(RS)-1i] 被评估为 GABA(B)R 激动剂。化合物 1a 是 GABA(B) 受体的激动剂,在用 GABA(B1b)/GABA(B2)/Gqz5 转染的 tsA201 细胞上的 EC₅₀ 值为 46 μM,是所有合成化合物中活性最强的同系物。
