生物活性

CNDAC is a major metabolite of oral drug sapacitabine, and a nucleoside analog.

体外研究
(In Vitro)

CNDAC-induced SSBs can be repaired by the transcription-coupled nucleotide excision repair pathway, whereas lethal DSBs are mainly repaired through homologous recombination. Deficiency in two Rad51 paralogs, Rad51D and XRCC3, greatly sensitize cells to CNDAC. The Rad51D-null cell line is approximately 50-fold more sensitive to CNDAC (IC50=0.006 µM) compared to 51D1.3, the Rad51D-repleted line (IC50=0.32 µM)[1]. CNDAC shows inhibitory activity against HL-60 and THP-1 cells with IC50s of 1.58 µM and 0.84 µM. CNDAC (10 μM) results in a significant drop in cell survival compared to the untreated on days 4, 7, and 14. CNDAC is more effective at reducing viability and inducing apoptosis than ara-C at equivalent concentrations in the THP-1 cell line, which is defined as displaying resistance to ara-C[2]. CNDAC induces DSBs, which are products of replication, rather than a consequence of induction of apoptosis. CNDAC causes DNA damage, and DNA-PK and ATR are dispensable for cell survival. CNDAC exhibits potent activity against human fibroblasts deficient in ATM or transfected with an empty vector, approximately 30-fold more than cells repleted with full-length ATM cDNA, with IC50s of 0.01 μM and 0.3 μM, respectively. CNDAC-induced DNA damage is repaired through the homologous recombination pathway[3].

Cell Assay
[2]

1×106 primary BM and PB cells are treated with 1 μM (low), 10 μM (medium), and 100 μM (high) of ara-C or CNDAC or 0.005 μM (low), 0.05 μM (medium) and 0.5 μM (high) mitoxantrone in 24 well plates at 37°C, 5% CO2, and 100% humidity for 4 days. Appropriate untreated controls are included. Postdrug treatment, both PB and BM non-adherent cells are washed to remove compound, replated on M2-10B4 stromal layers, and reincubated at 37°C, 5% CO2, 100% humidity. Cells are analyzed immediately posttreatment and following 3, 7, and 31 days postdrug removal.
