Conjugates of oligoarginine peptides with adenine, adenosine, adenosine-5'-carboxylic acid, and 5-isoquinolinesulfonic acid were synthesized and characterized as bisubstrate-analog inhibitors of cAMP-dependent protein kinase. Adenosine and adenine derivatives were connected to the N- or C-terminus of peptides containing four to six
