8-Bromoadenosine-3',5'-cyclic monophosphorothioate, RP-isomer sodium salt

Rp-8-Br-cAMPS is an analog of cAMP and an inhibitor of PKA. Rp-8-Br-cAMPS occupies cAMP binding sites on PKA type I regulatory subunits, thereby preventing PKA dissociation and activation. Rp-8-Br-cAMPS can be used in the study of tumors and retrovirus-induced immune deficiency. Rp-8-Br-cAMPS also inhibits insulin secretion[1][2][3].
