| abstract |
The invention concerns compounds of Formula (I), and pharmaceutically acceptable salts thereof: where such compounds act as TLR7 agonists and at the same time show advantageous selectivity over TLR8 and hERG, wherein the variable groups R 1 , R 2 and n are as defined herein. The invention also relates to methods for the preparation of such compounds and intermediates useful in the preparation thereof, to pharmaceutical compositions containing such compounds, to the use of such compounds in the preparation of medicaments, and to the use of such compounds in the treatment of conditions mediated by TLR7, such as allergic diseases, autoimmune diseases, viral diseases and, in particular, cancer. |
