Abstract
The present application relates to a novel compound having cancer therapeutic activity. The application also relates to a preparation method of the compounds and a pharmaceutical composition containing the compounds.
Description
Technical Field
The present application relates to a CD73 inhibitor having cancer therapeutic activity. The application also relates to a preparation method of the inhibitors and a pharmaceutical composition containing the inhibitors.
Background
Extracellular 5' -nucleotidase (CD 73) is a glycoprotein on the cell membrane and is present on the surface of cell membranes of various cell types, including endothelial cells, lymphocytes, stromal cells, tumor cells, and the like. CD73 is capable of catalyzing extracellular adenosine 5 '-phosphate (5' -AMP) to form adenosine, which can induce immunosuppressive effects, promoting tumor proliferation and/or metastasis. In addition, CD73 can also promote tumorigenesis by non-immune related mechanisms, such as promoting tumor angiogenesis, promoting adhesion of tumor cells to extracellular matrix proteins, and the like. Clinically, high levels of CD73 expression are associated with lymph node metastasis and poor prognosis for a variety of cancer types, CD73 has been found to be an independent prognostic factor in prostate and triple negative breast cancer patients.
Drugs targeting CD73 are one of the current areas of drug development hotspots, and existing varieties enter the clinical stage. The varieties under investigation include both large molecular antibodies and small molecular drugs. The application provides a novel-structure small-molecule CD73 inhibitor which has good anti-tumor activity.
