A novel polypeptide sequence having the formula
in which
A₁ is a hydrogen or at least one and no more than two amino acids selected from the group consisting of lysine and arginine,
A₂ is a tyrosine, phenylalanine or tryptophan residue,
A₃ is an arginine or lysine residue,
A₄ is at least one and no more than two amino acids selected from the group consisting of lysine and arginine, and
A₅ is an -OH or an NH₂, is described.
The polypeptide may be used in a pharmaceutical composition as an antimicrobial or antiviral agent, specifically as an anti-HIV agent.
