EHNA HYDROCHLORIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
EHNA (51350-19-7) inhibits phosphodiesterase 2 (PDE2) (IC50 = 0.8 – 5.5 μM in a variety of tissues and species) over PDE1, PDE3, or PDE4 (IC50 values > 100 μM).1,2 It also inhibits adenosine deaminase (ADA), IC50 = 1.2 and 1.5 μM in human RBCs and astrocytoma cells, respectively3, which may be responsible for its ability to induce apoptosis in malignant pleural mesothelioma cell lines4. Because it blocks breakdown of adenosine to inosine and hypoxanthine, EHNA prevents formation of free radical substrates, protecting against cardiac reperfusion-mediated injury.5 It inhibits differentiation and maintains expression of pluripotency markers in hESCs, but not through inhibition of PDEs or ADA.6
Chemische Eigenschaften
White Solid
Verwenden
A potent inhibitor of phosphodiesterase II (PDE II) (IC50=800nM). Does ot inhibit other PDE isozymes (IC50>100uM). Inhibits the retrograde transport motor, dynein. Also inhibits adenosine deaminase (Ki=4nM)
Verwenden
9-erythro-(2-Hydroxyl-3-nonyl)adenine is an intermediate in the synthesis of potent inhibitor of phosphodiesterase II.
Definition
ChEBI: (2R,3S)-EHNA is eHNA of absolute configuration 2R,3S. Selective inhibitor of cGMP-stimulated phosphodiesterase (PDE2) (IC50 = 0.8 - 4 mM). Also a potent inhibitor of adenosine deaminase. It has a role as an EC 3.5.4.4 (adenosine deaminase) inhibitor and an EC 3.1.4.* (phosphoric diester hydrolase) inhibitor. It is a conjugate base of a (2R,3S)-EHNA(1+). It is an enantiomer of a (2S,3R)-EHNA.
Biologische Aktivität
Selective inhibitor of cGMP-stimulated phosphodiesterase (PDE2) (IC 50 = 0.8 - 4 mM). Also a potent inhibitor of adenosine deaminase.
