Novel pyrazolopyrimidine derivatives as GSK-3 inhibitors
摘要:
A series of [1-aryl-1H-pyrazolo[3,4-d]pyrimidin-4-yl]arylhydrazones were discovered as novel inhibitors glycogen synthase kinase-3 (GSK-3). Based on initial modeling a detailed SAR was constructed. Modification of the interior binding aryl ring (Art) determined this to be a tight binding region with little room for modification. As predicted from the model, a large variety of modifications could be incorporated into the hydrazone aryl ring. This work led to GSK-3 inhibitors in the low nano-molar range. (C) 2004 Elsevier Ltd.
