ABSTRACT:
Described herein are chimeric peptides comprising a soluble trimeric coiled-coil and all or a portion of the N-peptide region of HIV gp41. These molecules are stable, trimeric coiled-coils that inhibit HIV entry into cells, such as human cells. Such peptides can be further assessed to demonstrate their ability to serve as potent anti-HIV therapeutic molecules and thus, as therapeutic molecules or drugs.
