Abstract

La présente invention concerne un conjugué d'érythropoïétine à bioactivité supérieure comprenant une glycoprotéine érythropoïétine avec un groupe a - amino et des dérivés aldéhyde de polyéthylène glycol N-terminal, ladite glycoprotéine érythropoïétine étant sélectionnée dans le groupe formé de l'érythropoïétine humaine et de ses analogues, ledit dérivé aldéhyde de méthoxy polyéthylène glycol étant représenté par la formule PEG-R-CHO, dans laquelle R = un groupe alkyle représenté par la formule -(CH2)n dans laquelle n = 2 à 4. La formule du conjugué de la présente invention est PEG-R-CONH-EPO, formule dans laquelle R = un groupe alkyle représenté par la formule -(CH2)n dans laquelle n = 2 à 4. L'érythropoïétine de la présente invention est une érythropoïétine de recombinaison (rhEPO) produite dans des cellules animales. Ledit conjugué d'érythropoïétine est préparé par expression, fermentation, et purification de la protéine rhEPO dans des cellules animales de recombinaison, et par mise en réaction de l'EPO avec PEG-aldéhyde pour obtenir une EPO à PEG N-terminal par une réaction d'amination réductrice, celle-ci étant ensuite purifiée pour obtenir une EPO à PEG N-terminal pure.
