Title
(EN) INTRACELLULAR EXPRESSION OF CARBOXYPEPTIDASE G2 IN ENZYME PRODRUG THERAPY
(FR) EXPRESSION INTRACELLULAIRE DE CARBOXYPEPTIDASE G2 DANS UNE THERAPIE A BASE D'ENZYME ET DE PROMEDICAMENT
Abstract
(EN)
The invention provides a two-component system for gene-directed enzyme prodrug therapy which comprises: (a) a vector which encodes a carboxypeptidase which is expressed within a cell; and (b) a prodrug which can be converted into an active drug by said carboxypeptidase, useful in the treatment of tumours.
(FR)
Système à deux constituants pour une thérapie génique à base de promédicament et d'enzyme, comprenant: (a) un vecteur qui code une carboxypeptidase exprimée à l'intérieur d'une cellule et (b) un promédicament qui peut être converti en un médicament actif par ladite carboxypeptidase, utile dans le traitement des tumeurs.
