AI Article Synopsis

  • PDE2A inhibitors have shown potential in improving cognitive function in preclinical models, sparking interest in their further development.
  • Researchers developed a new, highly potent PDE2A inhibitor (PF-05085727) that effectively penetrates the brain and demonstrates significant biochemical changes related to PDE2A inhibition.
  • The compound also reverses cognitive impairments caused by NMDA antagonists in rodents, suggesting it could enhance NMDA signaling and holds promise for future clinical applications in cognition.

Article Abstract

Phosphodiesterase 2A (PDE2A) inhibitors have been reported to demonstrate in vivo activity in preclinical models of cognition. To more fully explore the biology of PDE2A inhibition, we sought to identify potent PDE2A inhibitors with improved brain penetration as compared to current literature compounds. Applying estimated human dose calculations while simultaneously leveraging synthetically enabled chemistry and structure-based drug design has resulted in a highly potent, selective, brain penetrant compound 71 (PF-05085727) that effects in vivo biochemical changes commensurate with PDE2A inhibition along with behavioral and electrophysiological reversal of the effects of NMDA antagonists in rodents. This data supports the ability of PDE2A inhibitors to potentiate NMDA signaling and their further development for clinical cognition indications.

Studies using acute or subchronic pharmacological inhibition of phosphodiesterase 2 A (PDE2A) have led to its proposal as a target for treatment of cognitive deficits associated with neuropsychiatric and neurodegenerative disease. However, the impact of continuous inhibition of PDE2A on memory is unknown. Moreover, the neuroanatomical regions mediating memory enhancement have not been categorically identified.

Recent clinical trials of drugs enhancing cyclic guanosine monophosphate (cGMP) signaling for cardiovascular diseases have renewed interest in cGMP biology within the kidney. However, the role of cGMP signaling in glomerular endothelial cells (GECs) and podocytes remains largely unexplored. Using acute kidney slices from mice expressing the FRET-based cGMP biosensor cGi500 in endothelial cells or podocytes enabled real-time visualization of cGMP.

Aims: Gene therapy with cardiac phosphodiesterases (PDEs), such as phosphodiesterase 4B (PDE4B), has recently been described to effectively prevent heart failure (HF) in mice. However, exact molecular mechanisms of its beneficial effects, apart from general lowering of cardiomyocyte cyclic adenosine monophosphate (cAMP) levels, have not been elucidated. Here, we studied whether gene therapy with two types of PDEs, namely PDE2A and PDE4B, can prevent pressure-overload-induced HF in mice by acting on and restoring altered cAMP compartmentation in distinct subcellular microdomains.

The selective design of competitive enzyme inhibitors is an extremely difficult task but necessary work for certain types of systems, such as the phosphodiesterase (PDE) system addressed in this article. In the PDE family, PDE2A and PDE9 respectively target the central nervous system and heart failure, and share many conserved amino acids at their binding sites. Therefore, gaining a deep understanding of the selective mechanisms of PDE2A/9A is crucial for designing highly selective drugs.

T-cell activation is a pivotal process of the adaptive immune response with 3',5'-cyclic adenosine monophosphate (cAMP) as a key regulator of T-cell activation and function. It governs crucial control over T-cell differentiation and production of pro-inflammatory cytokines, such as IFN-γ. Intriguingly, levels of intracellular cAMP differ between regulatory (Treg) and conventional T-cells (Tcon).
