POLYPEPTIDE TRANSITION METAL SALTS AND METHOD OF ENHANCING ANTI-HIV ACTIVITY OF POLYPEPTIDE

摘要

Novel transition metal salts of a polypeptide represented by formula (1), having a high antiviral activity against human immunodeficiency virus (HIV). These compounds stably exhibit an anti-HIV activity higher than the one exhibited by ionic salts thereof with ordinary pharmaceutically acceptable acids because they form complex salts. A representative salt is one represented by formula (1).
