Adenosine 3′,5′-Monophosphate and N 6 -2'- O -Dibutyryl-Adenosine 3′,5′-Monophosphate Transport in Cells

Abstract
Incubation of Strain L cells in 0.15 millimolar adenosine 3',5'-monophosphate (cyclic AMP) increase the intracellular level of cyclic AMP more than does incubation in dibutyryl cyclic AMP. The intracellular increase of cyclic AMP is greater with Strain L than with WI-38 cells. Similarly, cell division of Strain L cells is inhibited more by cyclic AMP. The experiments do not, support the belief that dibutyryl cyclic AMP is transported better than cyclic AMP.
