Development of dual V1a/V2 antagonists containing triazolobenzazepine scaffold

Eur J Med Chem. 2025 Feb 5:283:117069. doi: 10.1016/j.ejmech.2024.117069. Epub 2024 Nov 28.

Abstract

The development of a dual V1a/V2 antagonist compound is a complex and challenging task. Conivaptan is up to now the only known V1a/V2 antagonist which was approved for the treatment of euvolemic hyponatremia. Previously, we reported RGH-122, a novel selective V1a antagonist compound. Herein, we describe several promising dual antagonist compounds, which are derived from RGH-122 by using modifications in its tail region. These modifications can result in excellent binding affinity on both V1a and V2 receptors.

Keywords: In silico docking; Triazolobenzazepine; V1a/V2 dual antagonist.
