MAP kinase inhibitors

[Christopher B. Chambers]

Hi to all of you hard-working neuroscientists!
Does anyone know of any inhibitors of mitogen-activated protein kinase 
(MAPK), glycogen-synthase kinase-3 (GSK-3), or tau-protein kinase?  I 
have searched through a variety of catalogs but have only been able to 
find inhibitors of PKA, PKC, Ca+2/Calmodulin-dependent protein kinase, 
etc.  Any and all information would be greatly appreciated.
