N6-cyclopentyladenosine inhibits proliferation of murine haematopoietic progenitor cells in vivo.

Effects of N6-cyclopentyladenosine (CPA), the selective adenosine A1 receptor agonist, on bone marrow haematopoietic progenitor cells for granulocytes and macrophages (CFC-GM) were investigated by utilizing the model of haematopoietic damage induced by 5-fluorouracil. Experiments were performed in vivo on B10CBAF1 mice. A single i.
