dibutyryl-cyclic adenosine monophosphate ( 1 mm ) caused significant potentiation of the decrease in [ 3h ] prazosin-binding caused by a submaximal ( 10 nm ) but not a maximal ( 10 microm ) concentration of norepinephrine , suggesting that cyclic adenosine monophosphate may act at a distal step in common with norepinephrine to reduce alpha-adrenergic receptor number .
