Patent

CA 2162689

The present invention provides purified and isolated polynucleotides encoding Type I ribosome-inactivating proteins (RIPs) and analogs of the RIPs having a cysteine available for disulfide bonding to targeting molecules. Vectors comprising the polynucleotides and host cells transformed with the vectors are also provided. The RIPs and RIP analogs are particularly suited for use as components of cytotoxic therapeutic agents of the invention which include gene fusion products and immunoconjugates. Cytotoxic therapeutic agents or immunotoxins according to the present invention may be used to selectively eliminate any cell type to which the RIP component is targeted by the specific binding capacity of the second component of the agent, and are suited for treatment of diseases where the elimination of a particular cell type is a goal, such as autoimmune disease, cancer and graft-versus-host disease.

Cette invention concerne des polynucléotides purifiés et isolés codant des protéines inactivant des ribosomes de type I (RIP) et des analogues des RIP ayant une cystéine disponible pour une liaison bisulfure sur des molécules de ciblage. Des vecteurs comprenant les polynucléotides et des cellules hôtes transformées avec les vecteurs sont également décrits. Les RIP et leurs analogues sont particulièrement adaptés pour servir de composants dans les agents thérapeutiques cytotoxiques de cette invention qui comprennent des produits de fusion génique et des immunoconjugués. Les agents thérapeutiques cytotoxiques de cette invention peuvent être utilisés pour éliminer sélectivement n'importe quel type de cellule sur lequel est ciblé le composant RIP par capacité de liaison spécifique du deuxième composant de l'agent, et sont adaptés au traitement des maladies dans lesquelles l'objectif est l'élimination d'un type de cellule particulière, telles que les maladies auto-immunes, le cancer et la maladie du greffon contre l'hôte.
