Identification
- Summary
Decitabine is a chemotherapeutic pyrimidine nucleoside analogue used for the treatment of myelodysplastic syndromes (MDS) by inducing DNA hypomethylation and corresponding alterations in gene expression.
- Brand Names
- Dacogen, Inqovi 5 Tablet Pack
- Generic Name
- Decitabine
- DrugBank Accession Number
- DB01262
- Background
Myelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic neoplasms with variable underlying etiology and presentation, including neutropenia and thrombocytopenia. Further mutations leading to increased proliferation of cancerous cells can eventually lead to secondary acute myeloid leukemia, which has a poor prognosis.9,10 Among treatment options, nucleoside analogues such as decitabine and azacitidine integrate into cellular DNA and inhibit the action of DNA methyltransferases, leading to global hypomethylation and related downstream therapeutic benefits.3,4,5,8,11
Decitabine was developed by MGI Pharma/SuperGen Inc. and was approved by the FDA for the treatment of MDS on February 5, 2006. It was first marketed under the name Dacogen®.11 It is also available as an oral combination product together with the cytidine deaminase inhibitor cedazuridine.

- Pharmacodynamics
Decitabine is a prodrug analogue of the natural nucleotide 2’-deoxycytidine, which, upon being phosphorylated intracellularly, is incorporated into DNA and exerts numerous effects on gene expression.3,4,5,8,11 The use of decitabine is associated with neutropenia and thrombocytopenia. In addition, decitabine can cause fetal harm in pregnant women; effective contraception and avoidance of pregnancy are recommended during treatment with decitabine.11
- Mechanism of action
Myelodysplastic syndromes (MDS) are a group of hematopoietic neoplasms that manifest in peripheral cytopenias and may eventually progress to secondary acute myeloid leukemia (sAML). Included in the over 45 genes commonly mutated in MDS patients are those involved in DNA methylation and histone modification, and it is well-established that alteration of the epigenetic landscape is a feature of myeloid leukemias.9,10
Decitabine is considered a prodrug, as it requires transport into cells and subsequent phosphorylation by distinct kinases to generate the active molecule 5-aza-2'-deoxycytidine-triphosphate, which is incorporated by DNA polymerase during DNA replication.3,5,6,7,8,11 Once incorporated into DNA, decitabine is recognized as a substrate by DNA methyltransferase enzymes (DNMTs), specifically DNMT1, but due to the presence of an N5 rather than C5 atom, traps the DNMT through the irreversible formation of a covalent bond.6,7 At low concentrations, this mode of action depletes DNMTs and results in global DNA hypomethylation while at high concentrations, it additionally results in double-strand breaks and cell death.4,7,8
The general hypothesis regarding decitabine's therapeutic efficacy is that the global hypomethylation it induces results in the expression of previously silent tumour suppressor genes.1,2,3,4,5,6,7,8,11 However, there are other putative mechanisms also related to this change in DNA methylation, including indirect alteration of transcription through effects on transcription factors, indirectly altering histone modifications and chromatin structure, and activating pathways involved in DNA damage response.3,5,7,8 The overall effect of decitabine is a decrease in neoplastic cell proliferation and an increase in the expression of tumour suppressor genes.

Decitabine administered intravenously at 15 mg/m2 for three hours every eight hours over three days resulted in a Cmax of 73.8 ng/mL (66% coefficient of variation, CV), an AUC0-∞ of 163 ng*h/mL (62% CV), and a cumulative AUC of 1332 ng*h/mL (95% CI of 1010-1730).11
Similarly, decitabine at 20 mg/m2 for one hour once daily over five days resulted in a Cmax of 147 ng/mL (49% CV), an AUC0-∞ of 115 ng*h/mL (43% CV), and a cumulative AUC of 570 ng*h/mL (95% CI of 470-700).11
- Volume of distribution
Decitabine as an apparent volume of distribution of 4.59 ± 1.42 L/kg.4
- Protein binding
Decitabine exhibits negligible (< 1%) plasma protein binding.5,11
- Metabolism
Decitabine is phosphorylated inside cells by the sequential action of deoxycytidine kinase, nucleotide monophosphate kinase, and nucleotide diphosphate kinase, prior to being incorporated into newly synthesized DNA by DNA polymerase.3,6,7,8 Decitabine not incorporated into cellular DNA undergoes deamination by cytidine deaminase followed by additional degradation prior to excretion.3,6,8

- Toxicity
Decitabine has demonstrated mutagenic potential in L5178Y mouse lymphoma cells and an Escherichia coil lac-I transgene within the colonic DNA of mice. Decitabine treatment increased chromosomal rearrangements in fruit fly larvae. In mouse models, decitabine exposure in utero (approximately 7% of the recommended daily dose) resulted in decreased weight and decreased male fertility. Adult male mice administered with between 0.3 and 1% of the recommended daily dose of decitabine three times a week for seven weeks had smaller testes with abnormal histology, decreased sperm count, and decreased fertility.11
There is no known antidote for decitabine overdose. Patients experiencing an overdose are at an increased risk of severe adverse effects such as myelosuppression, including prolonged and severe neutropenia and thrombocytopenia. Symptomatic and supportive measures are recommended.11

- Curator comments
- DNMT1 acts to methylate newly synthesized hemimethylated DNA during cellular division and is therefore thought to be the primary target for irreversible covalent modification by decitabine incorporated into DNA.
- General Function
- Methylates CpG residues. Preferentially methylates hemimethylated DNA. Associates with DNA replication sites in S phase maintaining the methylation pattern in the newly synthesized strand, that is essential for epigenetic inheritance. Associates with chromatin during G2 and M phases to maintain DNA methylation independently of replication. It is responsible for maintaining methylation patterns established in development. DNA methylation is coordinated with methylation of histones. Mediates transcriptional repression by direct binding to HDAC2. In association with DNMT3B and via the recruitment of CTCFL/BORIS, involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9. Probably forms a corepressor complex required for activated KRAS-mediated promoter hypermethylation and transcriptional silencing of tumor suppressor genes (TSGs) or other tumor-related genes in colorectal cancer (CRC) cells (PubMed:24623306).

- DNMT3A and 3B are primarily responsible for establishing the DNA methylation landscape during development. Some evidence exists to suggest that decitabine may inhibit these enzymes, though it is likely that DNMT1 is the main methylase involved in the mechanism of action of decitabine.
- General Function
- Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development (PubMed:12138111, PubMed:16357870, PubMed:30478443). DNA methylation is coordinated with methylation of histones (PubMed:12138111, PubMed:16357870, PubMed:30478443). It modifies DNA in a non-processive manner and also methylates non-CpG sites (PubMed:12138111, PubMed:16357870, PubMed:30478443). May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1 (By similarity). Plays a role in paternal and maternal imprinting (By similarity). Required for methylation of most imprinted loci in germ cells (By similarity). Acts as a transcriptional corepressor for ZBTB18 (By similarity). Recruited to trimethylated 'Lys-36' of histone H3 (H3K36me3) sites (By similarity). Can actively repress transcription through the recruitment of HDAC activity (By similarity). Also has weak auto-methylation activity on Cys-710 in absence of DNA (By similarity)

- General Function
- Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. May preferentially methylates nucleosomal DNA within the nucleosome core region. May function as transcriptional co-repressor by associating with CBX4 and independently of DNA methylation. Seems to be involved in gene silencing (By similarity). In association with DNMT1 and via the recruitment of CTCFL/BORIS, involved in activation of BAG1 gene expression by modulating dimethylation of promoter histone H3 at H3K4 and H3K9. Isoforms 4 and 5 are probably not functional due to the deletion of two conserved methyltransferase motifs. Functions as a transcriptional corepressor by associating with ZHX1. Required for DUX4 silencing in somatic cells (PubMed:27153398)

- Histone deacetylase that catalyzes the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4) (PubMed:16762839, PubMed:17704056, PubMed:28497810). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events (PubMed:16762839, PubMed:17704056). Histone deacetylases act via the formation of large multiprotein complexes (PubMed:16762839, PubMed:17704056). Acts as a component of the histone deacetylase NuRD complex which participates in the remodeling of chromatin (PubMed:16428440, PubMed:28977666). As part of the SIN3B complex is recruited downstream of the constitutively active genes transcriptional start sites through interaction with histones and mitigates histone acetylation and RNA polymerase II progression within transcribed regions contributing to the regulation of transcription (PubMed:21041482). Also functions as a deacetylase for non-histone targets, such as NR1D2, RELA, SP1, SP3, STAT3 and TSHZ3 (PubMed:12837748, PubMed:16285960, PubMed:16478997, PubMed:17996965, PubMed:19343227). Deacetylates SP proteins, SP1 and SP3, and regulates their function (PubMed:12837748, PubMed:16478997). Component of the BRG1-RB1-HDAC1 complex, which negatively regulates the CREST-mediated transcription in resting neurons (PubMed:19081374). Upon calcium stimulation, HDAC1 is released from the complex and CREBBP is recruited, which facilitates transcriptional activation (PubMed:19081374). Deacetylates TSHZ3 and regulates its transcriptional repressor activity (PubMed:19343227). Deacetylates 'Lys-310' in RELA and thereby inhibits the transcriptional activity of NF-kappa-B (PubMed:17000776). Deacetylates NR1D2 and abrogates the effect of KAT5-mediated relieving of NR1D2 transcription repression activity (PubMed:17996965). Component of a RCOR/GFI/KDM1A/HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development (By similarity). Involved in CIART-mediated transcriptional repression of the circadian transcriptional activator: CLOCK-BMAL1 heterodimer (By similarity). Required for the transcriptional repression of circadian target genes, such as PER1, mediated by the large PER complex or CRY1 through histone deacetylation (By similarity). In addition to protein deacetylase activity, also has protein-lysine deacylase activity: acts as a protein decrotonylase by mediating decrotonylation ((2E)-butenoyl) of histones (PubMed:28497810)

- Decitabine is not a direct substrate of UMP-CMP kinase; rather, monophosphorylated decitabine is subsequently converted to a diphosphate through the action of this enzyme. Eventual conversion to a triphosphate is required for integration into cellular DNA and the downstream mechanism of action of decitabine.
- General Function
- Catalyzes the phosphorylation of pyrimidine nucleoside monophosphates at the expense of ATP. Plays an important role in de novo pyrimidine nucleotide biosynthesis. Has preference for UMP and CMP as phosphate acceptors. Also displays broad nucleoside diphosphate kinase activity

- Decitabine is not a direct substrate of nucleoside diphosphokinase; rather, diphosphorylated decitabine is subsequently converted to a triphosphate through the action of this enzyme. The conversion to this triphosphate form is the final step required for integration into cellular DNA and the downstream mechanism of action of decitabine.
- General Function
- Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate. Possesses nucleoside-diphosphate kinase, serine/threonine-specific protein kinase, geranyl and farnesyl pyrophosphate kinase, histidine protein kinase and 3'-5' exonuclease activities. Involved in cell proliferation, differentiation and development, signal transduction, G protein-coupled receptor endocytosis, and gene expression. Required for neural development including neural patterning and cell fate determination. During GZMA-mediated cell death, works in concert with TREX1. NME1 nicks one strand of DNA and TREX1 removes bases from the free 3' end to enhance DNA damage and prevent DNA end reannealing and rapid repair
