General description

Chemical structure: nucleoside

Application

Sinefungin was used to inhibit global methyltransferases in breast cancer cell line, MCF72 and Jurkat cells.3 It was used as S-adenosylmethionine analogue in equilibrium FRET experiments.4

Biochem/physiol Actions

Sinefungin blocks the methylation of bases in DNA and RNA, such as 5-methylcytosine or N6-methyladenosine, suggesting a role in gene expression. In addition, sinefugin is involved in physiological processes such as aging and carcinogenesis.
Sinefungin blocks the methylation of bases in DNA and RNA, such as 5-methylcytosine or N6-methyladenosine, suggesting a role in gene expression. In addition, sinefugin is involved in physiological processes such as aging and carcinogenesis.
Methylation inhibition by sinefugin is often accompanied by an altered rate of cytosine deamination that is coupled to transition mutation in the DNA. Sinefugin inhibits Epstein-Barr viral activity and this inhibition is related to the change in DNA methylation and gene expression. It can cause a rate change in several restriction DNA endonuclease activities, including Mme I, which is not connected to the inhibition of the methytransferase activity.

A 2,2,7-trimethylguanosine (TMG) cap is a signature feature of eukaryal snRNAs, telomerase RNAs, and trans-spliced nematode mRNAs. TMG and 2,7-dimethylguanosine (DMG) caps are also present on mRNAs of two species of alphaviruses (positive strand RNA viruses of the Togaviridae family).

The folate and methionine cycles, constituting one-carbon metabolism, are critical pathways for cell survival. Intersecting these two cycles, 5,10-methylenetetrahydrofolate reductase (MTHFR) directs one-carbon units from the folate to methionine cycle, to be exclusively used for methionine and S-adenosylmethionine (AdoMet) synthesis.

Coronaviruses modify their single-stranded RNA genome with a methylated cap during replication to mimic the eukaryotic mRNAs. The capping process is initiated by several nonstructural proteins (nsp) encoded in the viral genome. The methylation is performed by two methyltransferases, nsp14

Mutations in many genes that control the expression, the function, or the stability of telomerase cause telomere biology disorders (TBDs), such as dyskeratosis congenita, pulmonary fibrosis, and aplastic anemia. Mutations in a subset of the genes associated with TBDs cause

Molecular cancer therapeutics, 8(6), 1579-1588 (2009-06-11)
DNA methylation, histone modifications, and nucleosomal occupancy collaborate to cause silencing of tumor-related genes in cancer. The development of drugs that target these processes is therefore important for cancer therapy. Inhibitors of DNA methylation and histone deacetylation have been approved
