1H-PYRROLO[3,2-C]PYRIDINE AND 1H-PYRROLO[2,3-C]PYRIDINE DERIVATIVES AS TLR9 INHIBITORS FOR THE TREATMENT OF FIBROSIS

Abstract

The present invention relates to 1H-pyrrolo[3,2-c]pyridine and 1H-pyrrolo[2,3-c]pyridine derivatives of formula (I) or a salt thereof. The present compounds are inhibitors of TLR9 and useful in treating preventing, or slowing fibrotic diseases, such as e.g. liver fibrosis, renal fibrosis, biliary fibrosis or pancreatic fibrosis, nonalcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), chronic kidney disease, diabetic kidney disease, primary sclerosing cholangitis (PSC) or primary biliary cirrhosis (PBC), or idiopathic pulmonary fibrosis (IPF).
