title: Liquid-phase synthesis of a pegylated adenosine-oligoarginine conjugate, cell-permeable inhibitor of cAMP-dependent protein kinase.
abstract: An adenosine-oligoarginine conjugate (ARC) was assembled in a stepwise manner on a poly(ethylene glycol) carrier. The pegylated conjugate inhibited cAMP-dependent protein kinase with IC(50)=460 nM and the cellular uptake of its BODIPY FL derivative was demonstrated and compared to that of free ARC with fluorescence microscopy.
