in contrast , the rate and degree of cell killing were dependent upon concentrations when cells were exposed to increasing amounts of 4-aminopyrrolo ( 2,3-d ) pyrimidine-beta-d-ribofuranoside or to 2-fluoroadenosine , indicating that these analogs are not cell-cycle-stage-specific and that nonreplicating cell populations may be sensitive to them .
