  The present invention relates to kinase inhibitor compounds and derivatives thereof as well as compositions comprising them for the treatment of neurological disorders such as Alzheimers' disease, Parkinsons' disease, obesity, hypertension and the like. These pyridazinone derivatives particularly inhibit the metabolic activity of glycogen synthase kinase —3β (GSK-3β) which is believed to cause the neurodegeneration that results in these diseases.

  本发明涉及激酶抑制剂化合物及其衍生物，以及包含它们的组合物，用于治疗诸如阿尔茨海默病、帕金森病、肥胖症、高血压等神经系统疾病。这些吡啶酮衍生物尤其抑制糖原合酶激酶-3β（GSK-3β）的代谢活性，据信这种活性导致了这些疾病的神经退行性变化。
