title: 6-[1-(2,6-difluorophenyl)ethyl]pyrimidinones antagonize cell proliferation and induce cell differentiation by inhibiting (a nontelomeric) endogenous reverse transcriptase.
abstract: Two 2,6-difluoro-DABO derivatives (MC 1047, 1, and MC 1220, 2, respectively) were tested against endogenous, nontelomeric reverse transcriptase (endo-RT) in human differentiating cell systems to investigate their antiproliferative and cytodifferentiating activity. The two compounds significantly reduced cell proliferation and facilitated the morphological differentiation of cells. These results propose F(2)-DABOs as useful tools in preventive and/or curative therapy to counteract the loss of differentiation in dedifferentiating pathologies and as antiproliferative drugs in tumor therapy.
