E. Maronde et al., Direct comparison of the potency of three novel cAMP analogs to induce CREB-phosphorylation in rat pinealocytes, J PINEAL R, 31(2), 2001, pp. 183-185
A modified analog of cyclic adenosine 3',5'-monophosphate (cAMP), Sp-adenos
ine-3',5'-monophosphorothioate, designed to be highly membrane-permeable an
d resistant towards phosphodiesterases was found to induce the phosphorylat
ion of the cAMP-regulated transcription factor cyclic AMP-responsive elemen
t binding protein in cultured rat pinealocytes more efficiently than previo
usly described cAMP analogs.
