Synthesis and biological evaluation of new derivatives of 2-substituted 4-hydroxybutanamides as GABA uptake inhibitors
摘要:
This study presents the synthesis of novel substituted 4-hydroxybutanamides and their influence on the activity of murine GABA transport proteins GAT1-GAT4. The active compounds, derivatives of N-aryl-alkyl-2-(4-diphenylmethylpiperazin-1-yl)-4-hydroxybutyramide, are characterized by pIC(50) values in range of 3.92-5.06 and by slight subtype-selectivity. Among them N-4-chlorobenzylamide was the most potent GAT inhibitor (mGAT3), while N-benzylamide was the most active in GAT1-binding assay (pK(i) = 4.96). The results pointed out that benzhydryl and benzylamide moieties are crucial for the activity of this class of compounds as murine GAT inhibitors. (C) 2010 Elsevier Masson SAS. All rights reserved.
