Abstract

Herein, we report the discovery of an effective strategy to modulate liabilities related to affinity of previously disclosed bicyclohexane MCHR-1 antagonists for the hERG channel. This paper describes one of several strategies incorporated to limit hERG binding via modifications of a terminal aryl group in an otherwise promising bicyclohexyl urea series.
