protein kinase A inhibitors

[Stephen Amato]

     I am studying signal transduction pathways involved in mediating
signals from B cell surface receptors to the nucleus.  I suspect that one
of these pathways involves protein kinase A.  Therefore, I am looking for
specific inhibitors of this kinase to confirm these suspicions. Does
anyone know of any specific inhibitors of protein kinase A?  If so do you
know where I could buy these reagents?
