| abstract |
The invention relates to the use of purine derivatives for the production of medicaments for the treatment of mucoviscidosis and diseases related to protein addressing errors in cells, said derivatives being of formula (I): where R2, R6 and R9, independently = halogen, a R-NH-, R-NH-NH-, NH2-R'-NH- or R-NH-R'-NH- group, where R = straight or branched chain saturated or unsaturated alkyl, aryl, cycloalkyl, or heterocyclyl group, R' = straight or branched chain, saturated or unsaturated alkylene, arylene or cycloalkylene, R and R' each include 1 to 8 carbon atoms optionally substituted with one or more -OH, halogen, amino or alkyl groups, R2 furthermore may be a heterocycle optionally with a straight or branched chain saturated or unsaturated alkyl, aryl or cycloaryl or a heterocycle optionally substituted by one or more -OH, halogen, amino or alkyl groups, R9 furthermore may be a straight or branched chain saturated or unsaturated alkyl, aryl or cycloalkyl and R2 and R9 furthermore may be hydrogen with the exception of 2-(2-hydroxyethylamino)-6-benzylamino-9-methylpurine. |
