[Description]

WIN 66306 is a cyclic heptapeptide antagonist of neurokinin-1 (NK1) and NK2 receptors originally isolated from A. flavipes. It binds to NK1 and NK2 receptors and inhibits contractions induced by substance P in isolated guinea pig ileum in a concentration-dependent manner.
[Uses]

WIN 66306 is a cyclic heptapeptide that can be isolated from an Aspergillus species. WIN 66306 is a neurokinin antagonist with antagonistic effects on both NK1 and NK2 receptors[1][2].
