yellow fluffy powder | [Uses]
6-Nitroveratraldehyde has been used in the preparation of no-carrier-added 6-18F-fluoro-L-dopa, fundamental tracer for cerebral positron emission tomography studies of dopaminergic system in humans and o-nitroaryl-bis(5-methylfur-2-yl)methanes, versatile synthons for the synthesis of nitrogen-containing heterocycles. DMNB is also an enzyme involved in the non-homologous end-joining (NHEJ) pathway of double-stranded DNA break (DSB) repair. It is also used for synthesizing analogs of alpha-asarone. | [Definition]
ChEBI: 4,5-dimethoxy-2-nitrobenzaldehyde is a C-nitro compound and an aromatic ether. | [General Description]
A cell-permeable vanillin derivative that acts as a potent and selective inhibitor of DNA-dependent protein kinase (DNA-PK) activity (IC50 = 15 μM) and DNA-PK-mediated double strand break (DSB) DNA repair by non-homologous DNA-end-joining (NHEJ). Reported to effectively sensitize cells to Cisplatin (Cat. No. 232120). Does not affect the activities of PKC or Chk2. | [Biological Activity]
Inhibitor of DNA-dependent protein kinase (DNA-PK) (IC 50 = 15 μ M), an enzyme involved in the non-homologous end-joining (NHEJ) pathway of double-stranded DNA break (DSB) repair in human cells. Displays 100-fold higher potency than its analog vanillin and does not affect PKC activity. Produces lethal effects on cisplatin-treated D5037 cells upon continuous exposure. | [Biochem/physiol Actions]
Cell permeable: yes | [Purification Methods]
The aldehyde is purified by dissolving 9g in 200mL of boiling 95% EtOH, and set aside overnight to crystallise. It is then dried in vacuo at 50o and recrystallised from 110mL of 95% EtOH to give 6-7g of aldehyde with m 132-133o. Crystallisation from aqueous EtOH provides light yellow needles. It is light sensitive and should be stored in the dark [Fetscher Org Synth Coll Vol 4 735 1963]. [Beilstein 8 H 262, 8 I 610, 8 II 290, 6 III 2065, 6 IV 1785.] |
