| Description | 3-Deazaneplanocin A hydrochloride is an inhibitor of histone methyltransferase. | |||||
| Targets | histone methyltransferase | |||||
| Cell experiment:[1] | |
| Cell lines | Human acute myeloid leukemia (AML) cell |
| Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
| Reacting condition | 100-750 nM; 24-72h |

| Animal experiment:[2] | |
| Animal models
| Sprague-Dawley rats (120–140 g) |
| Dosage form
| 5μM DZNep for 24 h pre-treatment before experiment, orally taken with diets |
| Application | DZNep significantly reduced EZH2 expression and activity, and it increased lipid accumulation, inflammatory molecules and microRNAs in non-alcoholic fatty liver disease (NAFLD) mouse model. |
| Other notes
| Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

3-Deazaneplanocin A (DZNep) hydrochloride is a selective inhibitor of ENZ2 inhibitor with IC50 value of 0.08-0.24 μM [1].
ENZ2 is a sub-unit of PRC2 and plays an important role in regulating cell proliferation and cell-cycle progression. It has been reported that ENZ2 is over-expressed in many tumors, including prostate, breast, bladder cancers and AML [2]. In HepG2 cell lines, DZNep treatment markedly induced the intracellular lipids increasement and TNF-αand TGF-βexpression in mRNA level by augmenting PA/OA-dependent lipid accumulation [3].
DZNep is a potent ENZ2 inhibitor. When tested with human acute myeloid leukemia (AML) HL-60 and OCI-AML3 cell lines, administration of DZNep induced cell apoptosis by depleting ENZ2, cyclin E and HOXA9 expressions and inducing p16, p21,p27 and FBXO32 expressions in a dose-dependent manner [2].
In high-fat/high-fructose diet fed (HFa/HFr-D) rat mouse model that resembles human NAFLD metabolically and histologically, DZNep functioned as the effective agent to anti-inflammatory and anti-fibrotic roles by inhibiting ENZ2 [3].
It is also reported that DZNep has the inhibitory activity for (SAHH (S-adenosylhomocysteine hydrolase) with Ki value of 50 pM [4].

Epigenetic Modifications with DZNep, NaBu and SAHA in Luminal and Mesenchymal-like Breast Cancer Subtype Cells.[Pubmed:27365379]
Cancer Genomics Proteomics. 2016 Jul-Aug;13(4):291-303.
BACKGROUND/AIM: Numerous studies have shown that breast cancer and epigenetic mechanisms have a very powerful interactive relation. The MCF7 cell line, representative of luminal subtype and the MDA-MB 231 cell line representative of mesenchymal-like subtype were treated respectively with a Histone Methyl Transferase Inhibitors (HMTi), 3-Deazaneplanocin hydrochloride (DZNep), two histone deacetylase inhibitors (HDACi), sodium butyrate (NaBu), and suberoylanilide hydroxamic acid (SAHA) for 48 h. MATERIALS AND METHODS: Chromatin immunoprecipitation (ChIP) was used to observe HDACis (SAHA and NaBu) and HMTi (DZNep) impact on histones and more specifically on H3K27me3, H3K9ac and H3K4ac marks with Q-PCR analysis of BRCA1, SRC3 and P300 genes. Furthermore, the HDACi and HMTi effects on mRNA and protein expression of BRCA1, SRC3 and P300 genes were checked. In addition, statistical analyses were used. RESULTS: In the MCF7 luminal subtype with positive ER, H3k4ac was significantly increased on BRCA1 with SAHA. On the contrary, in the MDA-MB 231 breast cancer cell line, representative of mesenchymal-like subtype with negative estrogen receptor, HDACis had no effect. Also, DZNEP decreased significantly H3K27me3 on BRCA1 in MDA-MB 231. Besides, on SRC3, a significant increase for H3K4ac was obtained in MCF7 treated with SAHA. And DZNEP had no effect in MCF7. Also, in MDA-MB 231 treated with DZNEP, H3K27me3 significantly decreased on SRC3 while H3K4ac was significantly increased in MDA-MB-231 treated with SAHA or NaBu for P300. CONCLUSION: Luminal and mesenchymal-like breast cancer subtype cell lines seemed to act differently to HDACis (SAHA and NaBu) or HMTi (DZNEP) treatments.
