Abstract
The adenosine analogue 3-deazaadenosine (c3 Ado) induces differentiation of human promyelocytic leukemia HL-60 cells in vitro, c3 Ado affects in vitro viability and growth of cells involved indirectly (cytokine-producing cells) and directly (transformed myeloid cells) in leukemic cell differentiation. Growth inhibition of proliferating cells is achieved at c3 Ado concentrations between 10–100 μM. Concentrations higher than 100 μM affect viability of proliferating and nonproliferating cells.
