This patent application discloses a series of l,3-dihydro-2H-indol-2-one derivatives targeting the vasopressin 1b receptor (V1b) or both the V1a and V1b receptors, as represented by Formula I. These vasopressin receptor antagonists exhibit significant therapeutic potential, particularly for the treatment of depression or anxiety, and hold promises for benefiting patients with reduced dosing frequency.
