Hazard Information

Uses

VX-984 is an orally active, potent, selective and BBB-penetrated DNA-PK inhibitor. VX-984 efficiently inhibits NHEJ (non-homologous end joining) and increases DSBs (DNA double-strand breaks). VX-984 can be used for glioblastomas (GBM) and non-small cell lung cancer (NSCLC) research. VX-984 is a de novo deuterium[1][2][3].

in vivo

VX-984 (0-100 mg/kg, Oral gavage, daily) inhibits radiation-induced DNA-PKcs phosphorylation in orthotopic brain tumor xenografts^[1].
VX-984 (0-50 mg/kg, Oral gavage, twice a day for 2 days) enhances the radiosensitivity of brain tumor xenografts^[1].

Animal Model:	Athymic female nude mice (6-8 weeks old, 7-8 mice/group, U251 intracerebral xenografts)^[1]
Dosage:	0, 50, and 100 mg/kg
Administration:	Oral gavage, daily, 1 or 4 hours before irradiation (10 Gy)
Result:	Reduced the levels DNA-PKcs phosphorylation after irradiation.

Animal Model:	Athymic female nude mice (6-8 weeks old, 7 mice/group, U251 intracerebral xenografts)^[1]
Dosage:	0, 50 mg/kg
Administration:	Oral gavage, twice a day, 30 minutes before and 4 hours following local irradiation of the tumor (3 Gy) for 3 consecutive days (3×3 Gy)
Result:	VX-984 treatment of U251 tumors alone had no significant effect on overall survival as compared with vehicle; radiation alone resulted in an increase in survival. VX-984 and radiation combination protocol increased tumor radiosensitivity, and significantly increased the survival of mice compared with radiation alone.
