Description

GCN2iB is an ATP-competitive inhibitor of a serine/threonine-protein kinase general control nonderepressible 2 (GCN2), with an IC50 of 2.4 nM.

GCN2iB shows an IC50 value of 2.4 nM for GCN2 and potent cellular activity. In a panel of 468 kinases, only GCN2 shows >99.5% inhibition, and three kinases (MAP2K5, STK10, and ZAK) show >95%inhibition at 1 μM GCN2iB, demonstrating high kinase selectivity[1].

In the antitumor activity study of the CCRF-CEM xenografts, ASNase or GCN2iB alone does not significantly affect tumor growth. Notably, a combination of ASNase and GCN2iB elicit potent antitumor activity (P=0.0002) with synergistic effects. In MV-4-11 and SU.86.86 xenografts, robust antitumor activity of the combination of GCN2iB and ASNase is observed with synergistic effect, respectively. ASNase/GCN2iB-treated tumors do not show significant growth even after drug cessation. The combination of ASNase and GCN2iB yield survival advantage compared with the vehicle treated control with synergistic effect[1].

Protocole (Protocol)

Animal experiment:

Mice[1]A suspension of CCRF-CEM, HPB-ALL, MV-4-11, or SU.86.86 cells (1×107 cells/site) is subcutaneously injected into the right flanks of 6-week-old female SCID mice. Tumor volume is calculated as volume =L×l2×1/2, where L represents the longest diameter across the tumor and l represents the corresponding perpendicular distance. Body weight is also measured. To assess the anti-tumor activity, mice with tumor mass ~200 mm3 are sorted into treatment groups (N=5/group). The tumors are monitored and mice are euthanized when an endpoint is reached, or at the end of the study, whichever comes first. From the next day of randomization, GCN2 inhibitors (e.g., GCN2iB, 10 mpk, twice a day) or ASNase is orally or intraperitoneally administered to mice bearing the xenografts for 7 to 10 days, respectively. T/C (%), an index of anti-tumor activity, is calculated by comparing the mean change in tumor volume during the treatment period in the control and treated groups[1].

Conseils généraux
Choisissez un solvant adapté selon les données de solubilité du produit. Après préparation, répartissez la solution mère en aliquotes afin d’éviter les cycles répétés de congélation-décongélation.
Utilisez les solutions mères dans les 6 mois si elles sont conservées à -80°C, ou dans le mois si elles sont conservées à -20°C.
Pour améliorer la solubilité, réchauffez le tube à 37°C et soniquez-le pendant une durée appropriée.
Conditions d’expédition
Les échantillons d’évaluation sont expédiés avec des blocs réfrigérants. Les autres formats sont expédiés à température ambiante ou, sur demande, avec des blocs réfrigérants.
