3-Deazaneplanocin A (C-c3Ado, DZNep; NSC617989) is an adenosine analogue acting as a competitive inhibitor of S-adenosylhomocysteine hydrolase and EZH2 (histone methyltransferase). It exhibits anticancer activity by inhibiting S-adenosylhomocysteine hydrolase with a Ki of 50 pM in a cell-free assay. 3-deazaneplanocin A demostrates excellent antiproliferative activity and high in vivo antitumor efficacy. It disrupts polycomb-repressive complex 2 (PRC2), and induces apoptosis, while inhibiting proliferation and metastasis, in cancer cells, including acute myeloid leukemia, breast cancer and glioblastoma. DZNep is a promising therapeutic agent for ovarian cancer cells, with potential to inhibit proliferation, induce apoptosis and decrease migration. In addition, 3-Deazaneplanocin A was also found to be effective for the treatment of Ebola virus disease, apparently interfering with the Ebola viruses ability to block interferon production, thus restoring the ability of immune system to rid the body of ebolavirus.
| ln Vitro |
3-Deazaneplanocin A is an effective inhibitor of histone methyltransferase EZH2. Treatment of OCI-AML3 cells with 3-Deazaneplanocin A (1.0 μM) causes a significant drop in the number of cells in the S phase (35.2%) and G2/M phases (6.3%) of the cell cycle (P<0.05), along with an increase in the accumulation of cells in the G0/G1 phase (58.5%). OCI-AML3 and HL-60 cell colony growth is inhibited when treated with 3-Deazaneplanocin A (200 nM to 2.0 μM) for 48 hours, in a dose-dependent manner[1]. 3-Deazaneplanocin A inhibits EZH2 expression, particularly after 72 hours (EZH2 expression in PANC-1, MIA-PaCa-2, and LPc006 cells, respectively, is reduced by 48%, 32%, and 36%)[2]. 3. In PANC-1 cells, dexapeneplanocin A exhibits negligible growth inhibition. Once exposed to the greatest dose (20 μM), almost 50% of these cells continue to develop. The IC0 values of MIA-PaCa-2 and LPc006 cells are significantly higher, at 1±0.3 and 0.1±0.03 μM, respectively[2]. 3-Deazaneplanocin A has an IC0 range of 0.08 to 0.24 μM and inhibits NSCLC cell line proliferation in a dose-dependent manner[3].

| ln Vivo |
When 3-Deazaneplanocin A and Panobinostat (PS) are administered together, NOD/SCID mice with acute myeloid leukemia (AML) caused by HL-60 cells have a considerably greater survival rate (P<0.05) than when PS, 3-Deazaneplanocin A, or vehicle alone are treated. The following are the median survival times: 36 days for control, 42 days for PS, 43 days for 3-Deazaneplanocin A, and 52 days for 3-Deazaneplanocin A plus PS[1]. Rats given physiological saline saw a time-dependent, gradual gain in weight (mean growth rate = 3.19%/day). When 20 mg/kg 3-Deazaneplanocin A is administered to rats, it not only significantly lowers their relative weight in comparison to their starting weight (−2.0%, −4.9%, and −1.2%) in the first three days after treatment, but it also slows their weight growth rate, which drops to 2.6% per day on the fourth day after the dose[4].
