AB All disulfide analogs (types I, II and III) of protegrin (PG)-1, an
18-residue antimicrobial peptide having two intramolecular disulfide
bonds, were synthesized using regioselective disulfide bond formation.
Random air-oxidation of the fully reduced PG-1 formed the type III PG-1.
In addition, a type III analog containing an amidated carboxy-terminal
residue was also prepared. Each analog showed significant and different
antibacterial and anti-human immunodeficiency virus (HIV) activity.
Deletion of two disulfide bridges caused a significant decrease in
activity.
