Preparation and use of ginsentides and ginsentide-like peptides
The present invention relates to the methods of solid-phase peptide synthesis or recombinant production of ginsentide or ginsentide-like peptides or salts thereof. Further provided are uses of the ginsentide or ginsentide-like peptides or salts thereof as α1-adrenergic receptor antagonists and vasorelaxants, nitric oxide-boosting agents, anti-thrombotic agents, anti-atherosclerotic agents, as protective agents against doxorubicin-induced cardiotoxicity, anti-ageing and adaptogenic agents, nutraceuticals, health supplements, or cosmetic ingredients.
1. A method of treating anxiety in a subject in need thereof, the method comprising administering to the subject a pharmaceutical composition comprising a ginsentide or ginsentide-like peptide or a pharmaceutically acceptable salt, said ginsentide or ginsentide-like peptide having the amino acid sequence set forth in any one of SEQ ID NO:1-14.
2. The method of claim 1 , wherein the ginsentide or ginsentide-like peptide has an amino acid sequence set forth is any one of SEQ ID NO:1, 3 or 8.
