Disclosed herein are antiviral peptides of the formula A-R.sup.8 -R.sup.9 -R.sup.10 -R.sup.11 -R.sup.12 -R.sup.13 -R.sup.14 -R.sup.15 B wherein A is from zero up to seven amino acid residues and includes a terminal hydrogen or a terminal N-acyl, or A is a phenylpropionyl with optional substitution of the para position of the phenyl, R.sup.8, R.sup.9, R.sup.10, R.sup.13, R.sup.14 and R.sup.15 are various amino acid residues with the stipulation that one or more of the three amino acid residues immediately preceeding R.sup.11 and R.sup.12 are independently Val, D-Val, Nva, D-Nva, Leu, D-Leu, Nle, D-Nle, Ile or D-Ile, and B is hydroxy, amino or lower alkylamino. The antiviral activity of the peptides can be enhanced by combining them with a protease inhibitor. The peptides and the combination are useful for the treatment of herpes viral infections in mammals.

Antiviral peptides and means for treating herpes infections

Disclosed herein is a combination of bacitracin and acyclovir or equivalent derivatives thereof. The combination, as well as bacitracin itself, are useful for treating herpes viral infections.

Antiviral pharmaceutical compositions and method of treating herpes

Disclosed herein are antiviral peptides of the formula A-R.sup.8 -R.sup.9 -R.sup.10 -R.sup.11 -R.sup.12 -R.sup.13 -R.sup.14 -R.sup.15 -B wherein A is from zero up to seven amino acid residues and includes a terminal hydrogen or a terminal N-acyl, or A is a phenylacetyl with optional substitution of the para position of the phenyl, R.sup.8, R.sup.9, R.sup.10, R.sup.13, R.sup.14 and R.sup.15 are various amino acid residues with the stipulation that one or more of the four amino acid residues immediately preceding R.sup.11 may optionally be deleted, R.sup.11 and R.sup.12 are independently Val, D-Val, Nva, D-Nva, Leu, D-Leu, Nle, D-Nle, Ile or D-Ile, and B is hydroxy, amino or lower alkylamino. The antiviral activity of the peptides can be enhanced by combining them with a protease inhibitor.
