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.
