CA 2708050

An expansion agent for hematopoietic stem cells and/or hematopoietic progenitor cells useful for improvement in the efficiency of gene transfer into hematopoietic stem cells for gene therapy useful for treatment of various hematopoietic disorders is provided. A method for expanding hematopoietic stem cells and/or hematopoietic progenitor cells, which comprises culturing hematopoietic stem cells and/or hematopoietic progenitor cells ex vivo in the presence of a compound represented by the formula (I) (wherein X, Y, X, Ar1, R1, R2, R3, R4 , R5, R6 and R7 are defined in the description), a tautomer or pharmaceutically acceptable salt of the compound or a solvate thereof. Image (I)

La présente invention concerne un agent pour amplifier des cellules souches hématopoïétiques et/ou des cellules progénitrices hématopoïétiques qui est utile en tant que procédé pour traiter diverses maladies hématopoïétiques et qui est utile pour améliorer l'efficacité du transfert de gènes vers des cellules souches hématopoïétiques en thérapie génique. L'invention concerne également un procédé pour amplifier des cellules souches hématopoïétiques et/ou des cellules progénitrices hématopoïétiques caractérisé par la culture de cellules souches hématopoïétiques et/ou de cellules progénitrices hématopoïétiques in vitro en présence d'un composé représenté par la formule (I) (X, Y, Z, Ar1, R1, R2, R3, R4, R5, R6 et R7 étant définis dans la description), d'un tautomère de celui-ci, d'un sel pharmaceutiquement acceptable de celui-ci ou d'un solvate de celui-ci.
