Abstract

L'invention concerne un médicament pour le traitement du sida et son procédé de préparation. Ledit médicament renferme essentiellement au moins un anticorps monoclonal dont l'antigène provient des épitopes de neutralisation ELDKWA se trouvant sur la protéine transmembranaire gp41 du virus de l'immunodéficience humaine et de ses variantes qui sont ELEKWA, ELNKWA et ELDEWA F. Le procédé de préparation du médicament de cette invention consiste à 1) synthétiser artificiellement au moins un épitope de neutralisation ELDKWA se trouvant sur la protéine transmembranaire gp41 du virus de l'immunodéficience humaine et/ou ses variantes ; 2) lier des polypeptides aux protéines porteuses correspondantes ou aux polypeptides porteurs ; 3) immuniser des animaux à l'aide de ces conjugués ; 4) préparer des hybridomes ; et 5) combiner les quatre groupes d'anticorps obtenus afin d'obtenir le médicament faisant l'objet de cette invention.
