  3-Thienyl- and 3-furylaminobutyric acids. Synthesis and binding GABAB receptor studies

  摘要：

  Baclofen (beta-(p-chlorophenyl)-GABA) is a selective agonist for the bicuculline-insensitive GABA(B) receptor. The search for new compounds that bind to the GABA(B) receptor is very important to clarify structural requirements. We report herein the synthesis and the binding studies of variously substituted 3-thienyl- and 3-furylaminobutyric acids. 4-Amino-3-(5-methyl-2-thienyl)butyric acid (5d) and 4-amino-3-(5-chloro-2-thienyl)butyric acid (5h) are potent and specific ligands for GABA(B) receptor. The IC50 values for the displacement of (R)-(-)-[H-3]baclofen are 1.34 and 0.61-mu-M for 5d and 5h, respectively, as compared to 0.33-mu-M for baclofen.

  of azide to meso-anhydrides has been developed, promoted by novel sulfamide-substituted Cinchona alkaloid-based catalysts. Readily available glutaric anhydrides can be smoothly converted to enantioenriched hemi-acyl azides and from there to either γ-amino acids or γ-lactams.

  已经开发了一种前所未有的有机催化工艺，该工艺涉及将叠氮化物不对称加成到内消旋酸酐中，并由新型磺酰胺取代的金鸡纳生物碱基催化剂促进。容易获得的戊二酸酐可以顺利转化为富含对映体的半酰基叠氮化物，然后再转化为 γ-氨基酸或 γ-内酰胺。
