The present invention relates to compounds, compositions and methods for treating fibrosis. In particular, compounds that inhibit or downregulate Sirtuin 1 (SIRT1) activity, which are particularly useful in the treatment of Idiopathic Pulmonary Fibrosis (IPF) are provided.

The present disclosure provides compounds of Formula (II) ##STR00001## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, W.sup.1, W.sup.2, W.sup.3, X, Y, and A are as described herein. The disclosed compounds modulate CD73 activity. The present disclosure also provides, pharmaceutical compositions containing these compounds, and methods of using these compounds for treating diseases associated with CD73 activity.

The present disclosure provides pharmaceutical compounds, compositions and methods, especially as they are related to compositions and methods for the treatment of tumors and related diseases related to the dysregulation of kinase (such as EGFR (including HER), Alk, PDGFR, but not limited to) pathways.

The present disclosure provides pharmaceutical compounds, compositions and methods, especially as they are related to compositions and methods for the treatment of tumors and related diseases related to the dysregulation of kinase (such as EGFR (including HER), Alk, PDGFR, but not limited to) pathways.

Disclosed is the use of the use of N.sup.2-quinoline or isoquinoline substituted purine derivatives in leukemia treatment, and the use of such purine derivatives in combination with a poly(ADP)-ribose polymerase (PARP) inhibitor and/or a chemotherapeutic agent in cancer treatment.

The invention relates to compounds, pharmaceutical compositions and methods useful for treating cancer, systemic or chronic inflammation, rheumatoid arthritis, diabetes, obesity, T-cell mediated autoimmune disease, diseases associated with over production of IL12/IL23, lysosomal storage disorders, filovirus infections, ischemia, and other complications associated with these diseases and disorders.

Disclosed are compounds of formula (I), and pharmaceutically acceptable salts thereof, which are inhibitors of the complement system. Also provided are pharmaceutical compositions comprising such a compound, and methods of using the compounds and compositions in the treatment or prevention of a disease or condition characterized by aberrant complement system activity.
