  "term": "Adenosine A2A receptor antagonist DZD2269",
  "field": "Oncology and biomedicine",
  "definition": "An immune checkpoint inhibitor and antagonist of the adenosine A2A receptor (A2AR; ADORA2A), with potential immunomodulating and antineoplastic activities. Upon administration, A2AR antagonist DZD2269 selectively binds to and inhibits A2AR expressed on T lymphocytes. This prevents tumor-released adenosine from interacting with the A2A receptors, thereby blocking the adenosine/A2AR-mediated inhibition of T lymphocytes. This results in the proliferation and activation of T lymphocytes, and stimulates a T-cell-mediated immune response against tumor cells. A2AR, a G protein-coupled receptor, is highly expressed on the cell surfaces of T cells and, upon activation by adenosine, inhibits their proliferation and activation. Adenosine is often overproduced by cancer cells and plays a key role in immunosuppression.",
