Sp-cAMPS
Sp-cAMPS, a cAMP analog, is potent activator of cAMP-dependent PKA I and PKA II. Sp-cAMPS is also a potent, competitive phosphodiesterase (PDE3A) inhibitor with a Ki of 47.6 µM. Sp-cAMPS binds the PDE10 GAF domain with an EC50 of 40 μM.

In Vitro
Treatment of hepatocytes with Sp-cAMPS, the stimulatory diastereomer of adenosine cyclic 3',5'-phosphorothioate, mimics the response seen with glucagon. The glucagon-stimulated increases in the level of Ca2+ can be mimicked by Sp-cAMPS[4].
