2',5'-Dideoxyadenosine is a potent and non-competitive adenylyl cyclase inhibitor via binding the P-site (IC50: 3 μM).2',5'-Dideoxyadenosine (20-150 mM), like adenosine, dependently and reversibly inhibits the positive inotropic and chronotropic effect of beta-adrenergic stimulation with isoproterenol (8-54 pmol) up to 70% and 50%, respectively.

β-Endorphin (1-27) (human) is an opioid antagonist that binds μ-, δ-, and κ-opioid receptors with Kis of 5.31, 6.17, and 39.82 nM, respectively. β-Endorphin (1-27) (human) inhibits β-Endorphin-induced and etorphine-induced analgesia.
