Insights into Ecto-5'-Nucleotidase as a New Target for Cancer Therapy : A Medicinal Chemistry Study
Ecto-5'-nucleotidase (ecto-5'-NT, 5'-NT, eN, CD73) is a membrane ecto-enzyme that is primarily responsible for the extracellular production of adenosine from AMP. Ecto-5'-NT is over expressed in various types of cancer cells, leading to elevated concentrations of adenosine in the tumor microenvironment. Adenosine has also been found to be important in cancer pathogenesis, showing strong immunosuppressive effects over antitumor T cells and macrophages and promoting neovascularization and cell adherence. These actions support tumor growth and development. It has been suggested that the inhibition of ecto-5'-NT results in lower extracellular concentrations of adenosine within the tumor microenvironment, which would directly affect cancer cells and render malignant cells more susceptible to host defense systems. Such mechanisms are proposed to represent promising new targets for cancer therapy. The aim of this review is to explore the biochemical and structural features of ecto-5'-NT, including a brief analysis of its active site by molecular modeling, as a means of evaluating whether the inhibition of this enzyme does indeed represent a feasible strategy for treating cancer. Known inhibitors and possible prototypes that could be used to target ecto-5'-NT during cancer therapy are also discussed.
