Biological Activity
| Description | Zebularine (NSC 309132, 4-Deoxyuridine) is a DNA methylation inhibitor that forms a covalent complex with DNA methyltransferases, also inhibits cytidinedeaminase with Ki of 2 μM in a cell-free assay. | ||||

| In vitro | Zebularine is a cytidine analogue containing a 2-(1H)-pyrimidinone ring, originally synthesized as a cytidine deaminase inhibitor. [2] Zebularine is shown to form a tight, covalent complex with bacterial methyltransferases. [1] In N. crassa, zebularine inhibits DNA methylation and reactivates a gene previously silenced by methylation. Zebularine is a global inhibitor of DNA methylation, similar to 5-Aza-CR, rather than a selective inhibitor. Zebularine induces the myogenic phenotype in 10T1/2 cells, which is a phenomenon unique to DNA methylation inhibitors. Zebularine reactivates a silenced p16 gene and demethylates its promoter region in T24 bladder carcinoma cells. Zebularine is only slightly cytotoxic to T24 cells. [3] Zebularine is preferentially incorporated into DNA and exhibits greater cell growth inhibition and gene expression in cancer cell lines compared to normal fibroblasts. In addition, zebularine preferentially depletes DNA methyltransferase 1 (DNMT1) and induces expression of cancer-related antigen genes in cancer cells relative to normal fibroblasts. [4] | ||||
| In vivo | Zebularine is only slightly cytotoxic to tumor-bearing mice (average maximal weight change in mice treated with 1000 mg/kg zebularine = 11% [95% CI = 4% to 19%]). Compared with those in control mice, tumor volumes are statistically significantly reduced in mice treated with high-dose zebularine administered by intraperitoneal injection or by oral gavage.

| Features | Very stable with half-life of ~44 h at 37°C in PBS at pH 1.0 and approx. 508 h at pH 7. |
