pde-1-in-2

PDE1-IN-2 is an PDE1 inhibitor(PDE1C, PDE1B and PDE1A with IC50 values of 6, 140 and 164 nM, respectvely).

PDE2/PDE10-IN-1 is an inhibitor of phosphodiesterase 2 (PDE2) and PDE10, with IC50 values of 29 nM and 480 nM, respectively.

Olprinone Hydrochloride, also known as Loprinone, is a phosphodiesterase (PDE) 3 potent inhibitor, exhibiting IC50 values of 150, 100, 0.35, and 14 μM for PDE1, PDE2, PDE3, and PDE4, respectively. It is utilized in heart failure research for its positive inotropic and vasodilative properties. It also exhibits anti-inflammatory activity [1] [2].

Theophylline (1,3-Dimethylxanthine) sodium glycinate is a potent phosphodiesterase (PDE) inhibitor that targets PDE3 to relax airway smooth muscle and is used in asthma and chronic obstructive pulmonary disease (COPD) research. It also functions as an adenosine receptor antagonist, histone deacetylase (HDAC) activator, and exhibits anti-inflammatory activity by increasing IL-10 levels and inhibiting NF-κB nuclear import, while inducing apoptosis [1] [2] [3] [4] [5].

Hcyb1 is a potent and specific inhibitor of phosphodiesterase 2 (PDE2). It exhibits a high degree of selectivity for inhibiting PDE2A with an IC50 value of 0.57 μM. In addition, Hcyb1 displays over 250-fold selectivity against other recombinant members of the PDE family. Moreover, its pharmacological actions include neuroprotective and antidepressant-like effects, which are believed to be mediated through the cAMP/cGMP-CREB-BDNF signaling pathway [1].
