The present application provides novel optionally substituted fused pyridine and pyrimidine bicyclic compounds and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in co-regulating FAK and/or Src activity by administering a therapeutically effective amount of one or more of the compounds to a subject. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the FAK and/or Src pathway. Advantageously, these compounds perform as dual FAK and/or Src inhibitors. A variety of conditions can be treated using these compounds and include diseases which are characterized by inflammation or abnormal cellular proliferation. In one embodiment, the disease is cancer.
The present invention provides a novel compound that has anti-RSV activity and that is useful in the prevention or treatment of an infection in which viruses of the subfamily Pneumovirinae, including respiratory syncytial virus (RSV), are involved, or a pharmaceutically acceptable salt thereof. Specifically, the present invention provides a compound represented by formula (I):
or a pharmaceutically acceptable salt thereof.
We present herein an approach for the enantioselective C3-functionalization of 2,1-benzothiazine 2,2-dioxides using N-heterocycliccarbene (NHC) catalysis. Our method involves a sequence of [3+3] cycloaddition and ring-opening reactions with different N- and O-nucleophiles, followed by silylation. Overcoming the challenge of selectivity targeting the C3 position, this protocol demonstrates a broad
