ABSTRACT

Introduction: There are considerable interests in the development of novel small-molecule CD73 inhibitors for the treatment of cancers, autoimmune diseases, precancerous syndromes, and other diseases associated with CD73 activity.

Areas covered: The application claims novel substituted benzothiadiazine derivatives as CD73 inhibitors for the treatment of cancer, precancerous syndromes, AIDS, autoimmune diseases, infections, atherosclerosis, and ischemia-reperfusion injury. Many of the exemplified compounds have pIC50 values between 5 to 8.4 against CD73.

Expert Opinion: These benzothiadiazine derivatives provide good leads for the discovery of potent CD73 inhibitors for the treatment of cancer and other diseases mediated by adenosine and its action on adenosine receptors.
