|Title:||Synthetic peptide inhibitors of HIV transmission|
|Abstract:||The present invention relates to peptides which exhibit potent anti-retroviral activity. The peptides of the invention comprise DP-178 (SEQ ID:1) ptides corresponding to amino acids 638 to 673 of the HIV-1.sub.LAI gp41 protein, and fragments, analogs and homologs of DP-178. The invention further relates to the uses of such peptides as inhibitory of human and non-human retroviral, especially HIV, transmission to uninfected cells.|

amino acid residues are presented by the single-letter code;
X comprises an amino group, an acetyl group, a 9-fluorenylmethoxy-carbonyl group, a hydrophobic group, or a macromolecule carrier group;
Z comprises a carboxyl group, an amido group, a hydrophobic group, or a macromolecular carrier group.
2. The peptide of claim 1 wherein X is a hydrophobic group.
3. The peptide of claim 2 wherein the hydrophobic group X is carbobenzoxyl, dansyl, or t-butyloxycarbonyl.
4. The peptide of claim 1 wherein Z is a hydrophobic group.
5. The peptide of claim 4 wherein the hydrophobic group Z is t-butyloxycarbonyl.
6. The peptide of claim 1 wherein X is a macromolecular carrier group.
