.beta.-peptide regions of polypeptides can serve as structural mimics of .alpha.-helices in wild type proteins. Because .alpha.-helices of one protein often bind to a target protein in a biological pathway, a polypeptide that contains a helical .beta.-peptide region can be used to disrupt this type of protein-protein binding. As a result, polypeptides that contain a helical ~- peptide region can be used to treat conditions involving this type of protein~ protein binding, such as viral infections and cell proliferation.

Selon l'invention, des régions ß-peptide de polypeptides peuvent faire office de mimétiques structuraux d'a-hélices dans des protéines de type sauvage. Etant donné que les a-hélices d'une protéine se lient souvent à une protéine cible dans une voie biologique, un polypeptide qui contient une région ß-peptide hélicoïdale peut être utilisé pour rompre ce type de liaison protéine-protéine. Ainsi, des polypeptides qui contiennent une région ß-peptide hélicoïdale peuvent être utilisés pour traiter des états impliquant ce type de liaison protéine-protéine, par exemple des infections virales et la prolifération cellulaire.
