On the WiDr cell line the dual effect of concentration and duration of exposure prior to irradiation was investigated. For MCF-7, ddC induced a significant modification of the dose response only with 24 and 48 h preincubation[1].;It is phosphorylated in T cells and other HIV target cells into its active triphosphate form, ddCTP. This active metabolite works as a substrate for HIV reverse transcriptase, and also by incorporation into the viral DNA, hence terminating the chain elongation due to the missing hydroxyl g MedChem Express HY-17392
