This paper describes the synthesis of 3-amino-3-(4-chlorophenyl)propanoic acid
and the corresponding phosphonic and sulfonic acids, lower homologues of
baclofen, phaclofen and saclofen respectively. The chlorinated acids were all
weak specific antagonists of GABA at the GABAB receptor,
with the sulfonic acid (pA2 4·0) being stronger
than the phosphonic acid (pA2 3·8) and carboxylic
acid (pA2 3·5).
本文介绍了 3-氨基-3-(4-氯苯基)丙酸以及相应的膦酸和磺酸的合成过程。

巴氯芬、法氯芬和沙氯芬的低级同系物。氯化酸都是
在 GABAB 受体上是 GABA 的弱特异性拮抗剂、
磺酸(pA2 4-0)强于膦酸(pA2 4-0)。
强于膦酸(pA2 3-8)和羧酸(pA2 3-5
酸(pA2 3-5)更强。
