Abstract:
Structure-guided design led to the identification of the novel, potent, and selective phosphodiesterase 2 (PDE2) inhibitor 12. Compound 12 demonstrated a >210-fold selectivity versus PDE10 and PDE11 and was inactive against all other PDE family members up to 10 μM. In vivo evaluation of 12 provided evidence that it is able to engage the target and to increase cGMP levels in relevant brain regions. Hence, 12 is a valuable tool compound for the better understanding of the role of PDE2 in cognitive impairment and other central nervous system related disorders.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
