摘要:
A method for treating cutaneous and corneal wounds as well as certain microbial-related diseases comprises topically applying a defensin peptide to the affected tissue. The compositions comprise a natural, synthetic, or analog defensin molecule having both a mitogenic activity capable of stimulating cell growth and an antimicrobial activity capable of inhibiting the growth of a wide variety of pathogens. In addition to therapeutic use, the defensins are useful as mitogens in cell and tissue culture media.
摘要:
Novel microbicidal compositions are provided which find use as preservatives, disinfectants, antigens and the like. Particularly, cationic oligopeptides of up to about thirty-five amino acids are provided having amino acid sequences substantially comparable to the amino acid sequences of cationic oligopeptides produced by macrophage. A conserved framework structure is provided.

摘要:
Peptide-based compounds containing four invariant cysteine residues which have been optionally oxidized to contain two intramolecular disulfide bonds, or modified forms where the cysteines are replaced are useful as preservatives and in preventing, treating, or ameliorating viral or microbial infection in animals and plants, and in inactivating endotoxin.
摘要:
Retrocyclin peptides are small antimicrobial agents with potent activity against bacteria and viruses. The peptides are nonhemolytic, and exhibit minimal in vitro cytotoxicity. A pharmaceutical composition comprising retrocyclin as an active agent is administered therapeutically to a patient suffering from a bacterial and/or viral infection, or to an individual facing exposure to a bacterial and/or viral infection, especially one caused by the HIV-1 retrovirus or other sexually-transmitted pathogens.
摘要:
Novispirin peptides are antimicrobial agents with potent activity against Gram-negative bacteria. The peptides are nonhemolytic, exhibit reduced in vitro cytotoxicity relative to other antimicrobial peptides, and were well-tolerated in vivo after intravenous injection. Novispirins also bind lipopolysaccharide (LPS), a property that may mitigate symptoms associated with Gram-negative bacterial infection. A pharmaceutical composition comprising novispirin as an active agent is administered to a patient suffering from or predisposed to a microbial infection, particularly Gram-negative bacterial infections.
