Synthesis and Pharmacological Characterization of Two Novel, Brain Penetrating P2X7 Antagonists
摘要:
The synthesis and preclinical characterization of two novel, brain penetrating P2X(7) compounds will be described. Both compounds are shown to be high potency P2X(7) antagonists in human, rat, and mouse cell lines and both were shown to have high brain concentrations and robust receptor occupancy in rat. Compound 7 is of particular interest as a probe compound for the preclinical assessment of P2X(7) blockade in animal models of neuro-inflammation.

The discovery of a series of novel, potent, and selective blockers of the cyclic nucleotide-modulated channel HCN1 is disclosed. Here we report an SAR study around a series of selective blockers of the HCN1 channel. Utilization of a high-throughput VIPR assay led to the identification of a novel series of 2,2-disubstituted indane derivatives, which had moderate selectivity and potency at HCN1. Optimization of this hit led to the identification of the potent, 1,1-disubstituted cyclohexane HCN1 blocker, 2-ethoxy- N-(( 1-(4-isopropylpiperazin-1-yl) cyclohexyl) methyl) benzamide. The work leading to the discovery of this compound is described herein. (C) 2011 Elsevier Ltd. All rights reserved.
