Biological Activity

Description 6-Diazo-5-oxo-L-norleucine (Diazooxonorleucine, L-6-Diazo-5-oxonorleucine, DON), an antibiotic isolated from Streptomyces, is a glutaminase antagonist with IC50 of ~1  mM for cKGA (kidney-type glutaminase). 6-Diazo-5-oxo-L-norleucine exhibits analgesic, antibacterial, antiviral and anticancer properties.
Targets
cKGA [1]
(Cell-free assay)
1 mM
In vitro

6-Diazo-5-oxo-L-norleucine appears to be positive in the in vitro chromosome aberration assay that it demonstrates dose dependent statistically positive increase in structural aberrations at 4 and 20 hour exposure without S9 and also at 4 hour exposure with S9.[2]
In vivo

6-Diazo-5-oxo-L-norleucine is evaluated for its in vivo clastogenic activity by detecting micronuclei in polychromatic erythrocyte (PCE) cells in bone marrow collected from the male mice dosed intravenously with 500, 100, 10, 1 and 0.1 mg/kg at 24 and 48 hour post dose. The in vivo micronucleus assay reveals a statistically positive response for micronucleus formation at 500, 100 and 10 mg/kg at 24 and 48 hour post dose.[2]
