Irreversibly-inactivated pepsinogen fragment and pharmaceutical compositions comprising this fragment for detecting, preventing, and treating HIV

摘要

The inventions provide an isolated antiviral peptide characterized by the amino acid sequence GDEPLENYLDTEYF (SEQ ID:NO 1) and a significant in vitro binding affinity for HIV-1 gp 120 and gp 41 and human CD4 cells. It has postulated anti-retroviral activity in vivo, particularly anti-HIV-1 activity. The inventions further provide pharmaceutical compositions comprising this peptide and methods for preventing, treating, and diagnosing HIV-1 infections and HIV-1 related conditions such as AIDS and ARC with these compositions.
