Synthesis, biological evaluation, and SAR dependencies for a series of novel aryl and heteroaryl substituted N-[3-(4-phenylpiperazin1-yl)propyl]-1,2,4-oxadiazole-5-carboxamide inhibitors of GSK-3 beta kinase are described. The inhibitory activity of the synthesized compounds is highly dependent on the character of substituents in the phenyl ring and the nature of terminal heterocyclic fragment of the core molecular scaffold. The most potent compounds from this series contain 3,4-di-methyl or 2-methoxy substituents within the phenyl ring and 3- pyridine fragment connected to the 1,2,4-oxadiazole heterocycle. These compounds selectively inhibit GSK-3 beta kinase with IC50 value of 0.35 and 0.41 mu M, respectively. (C) 2007 Elsevier Ltd. All rights reserved.
