CA 2384789

The present invention is directed to 9-substituted guanine derivatives in which the guanine moiety is linked to another moiety with physiological or pharmacological activity through a carboxamide linkage. The number of carbon atoms between the guanine moiety and the carboxamide linking group is typically from 1 to 6. In some cases, the chemical moieties can have carbon chains of different lengths within the moiety linked to guanine through the carboxamide linker. A large number of different chemical moieties can be linked to the guanine moiety. The invention also includes pharmaceutical compositions including the 9-substituted guanine derivatives and methods of use of the 9-substituted guanine derivatives.

La présente invention concerne des dérivés de guanine 9-substitués dans lesquels le groupe guanine est lié à un autre groupe ayant une activité physiologique ou pharmacologique via une liaison carboxamide. Le nombre d'atomes de carbone entre le groupe guanine et le groupe de liaison carboxamide vaut en général de 1 à 6. Parfois, les groupes chimiques peuvent comporter des chaînes carbonées de longueurs différentes à l'intérieur du groupe lié à la guanine via le groupe de liaison carboxamide. Un grand nombre de groupes chimiques différents peuvent être liés au groupe guanine. Cette invention concerne également des compositions pharmaceutiques comprenant des dérivés de guanine 9-substitués et des procédés d'utilisation des dérivés de guanine 9-substitués.
