Biological Activity

Description Adenosine Dialdehyde (ADOX) is an adenosine analog and S-adenosylmethionine-dependent methyltransferase inhibitor with an IC50 of 40 nM.
AdoHcy hydrolase [1]
40 nM
In vitro

Adenosine dialdehyde (AdOx), an indirect inhibitor that can be incorporated by cells. AdOx inhibits S-adenosyl-L-homocystein hydrolase, resulting in the accumulation of S-adenosyl-L-homo cystein (Adoicy), a product inhibitor of methyltransferases that utilize S-adenosyl-L-methionine (AdoMet) as the methyl group donor[2]. AdOx inhibited the Tax-activated NF-κB pathway, resulting in reactivation of p53 and induction of p53 target genes. Analysis of the NF-κB pathway demonstrated that AdOx treatment resulted in degradation of the IκB kinase complex and inhibition of NF-κB through stabilization of the NF-κB inhibitor IκBα. AdOx induced G2/M cell cycle arrest and cell death in HTLV-1-transformed but not control lymphocytes[4].

Alterations in one-carbon metabolism affect the distribution of endogenous PP2A and Tau at the plasma membrane. A, Western blot analysis of plasma membrane fractions (30 μg of proteins) purified from N2a cells incubated for 2 h with 50 μM adenosine dialdehyde (AdOx), 10 mM cycloleucine (CL), or vehicle alone (Control) in normal RPMI medium containing 1% dialyzed serum. B, the loss of LCMT1, methylated C, and Tau dephosphorylated at the Tau-1 epitope in the plasma membrane was associated with an increase of Tau phosphorylated at Ser-422 in cytosolic fractions purified from the same cells. pSer422, phospho-Ser-422. In Aand B, representative blots from three separate experiments are shown.

Cells (RAW-264.7) were treated with AdOx (5 µM) for 48 h, and lysates were immunoblotted for AUF1 isoforms. Loading control was α-tubulin.

In vivo AdOx exerts a potent inhibitory effect on the in situ growth of established murine neuroblastoma (MNB) tumors, prolongs the life span of tumor bearing mice, and does not suppress hematopoiesis when administered by steady state infusion. AdOx inhibits the replication of L1210 leukemia cells and increased life span approximately 40% when administered i.p. at a dose of 20 mg/kg/day until death[3].


Cell Research:


- Collapse
  • Cell lines: Hela cells
  • Concentrations: 0, 10, 20 or 40 μM
  • Incubation Time: 24 and 48 h
  • Method:

    Hela cells are grown in MEM medium supplemented with 10% fetal bovine serum at 37 ℃ in a 5% CO2 incubator. Treatment of cells with AdOx for various time periods was performed. The cells are harvested and washed with phosphate-buffered saline, resuspended in buffer A (phosphate-buffered saline with 5% glycerol, 1 mM sodium EGTA, 1 mM dithiothreitol, 0.5% Triton X-100 and Complete protease inhibitor cocktail).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
