A series of OX2R/OX1R dual orexin antagonists was prepared based on a proline bis-amide identified as a screening lead. Through a combination of classical and library synthesis, potency enhancing replacements for both amide portions were discovered. N-methylation of the benzimidazole moiety within the lead structure significantly reduced P-gp susceptibility while increasing potency, giving rise to good brain penetration. A compound from this series has demonstrated in vivo central activity when dosed peripherally in a pharmacodynamic model of orexin activity. Published by Elsevier Ltd.
