Abstract: Methods of treating cancer by preventing, mitigating, and/or inhibiting cancer metastasis in tumors expressing Epac by inhibiting the activity of exchange proteins directly activated by cyclic AMP (Epac) or one or more proteins within the Epac-induced carcinoma migration pathway.

Abstract: The invention provides a method of treating a cardiac disease by administering a pharmaceutically effective amount of at least one compound capable of inhibiting AC5 to a patient. The compound capable of inhibiting AC5 may be administered singly or in combination with another agent, such as, for instance a ?-blocker. In some embodiments, the AC5 inhibiting compound is 9-?-D-arabinofuranosyladenine (AraAde). The compound may be administered in an amount of about 1 to about 200 mg/kg/day, about 1 to about 100 mg/kg/day, about 10 to about 80 mg/kg/day, about 12 to about 40 mg/kg/day or about 15 to about 25 mg/kg/day. In some embodiments, the compound is administered parenterally. The cardiac disease may be, for instance, myocardial infarction (MI) or heart failure (HF). The compound capable of inhibiting AC5 may be administered alone or in conjunction with one or more other active agents.
