Waglerin 1 (Wtx-1) is a peptide originally isolated from the venom of the Wagler's pit viper (Trimeresurus wagleri). This 22 amino-acid peptide is a competitive antagonist of muscle nicotinic acetylcholine receptors. Waglerin 1 binds selectively to epsilon subunit of nAChR. Some studies have demonstrated that Waglerin 1 has an effect on ionotropic GABA receptors. It may potentiate or depress I(GABA) depending on the neurons. Some derivatives of Waglerin 1 are currently used in cosmetics to reduce wrinkles.
