EHNA Hydrochloride is a reversible adenosine deaminase inhibitor that selectively inhibits the cGMP-specific phosphodieterase (PDE2). At a 10µM concentration, EHNA has been shown to effectively and reversibly block the differentiation and maintain the pluripotency of the hES cell line SA121 in feeder- free cultures without exogenously added FGF for up to 30 passages. EHNA has also been used to study the cardioprotective and neuroprotective efforts during ischemia and in the study of cAMP/cGMP signaling.
