Dimephosphon Radioprotective Properties on the Model of Radiation Injury In Vivo

Area of Science:

• Radiation oncology
• Radiobiology
• Pharmacology

Background:

• Radiation therapy is a vital cancer treatment but causes toxicity to healthy tissues.
• Developing effective radioprotective agents is crucial in radiation oncology.
• Dimephosphon exhibits anti-acidotic, antitumor, and antioxidant activities.

Purpose of the Study:

• To investigate the radioprotective properties of Dimephosphon.
• To evaluate its effects on radiation-induced injury in an animal model.

Main Methods:

• Experimental modeling of radiation injury in CD-1 mice.
• Administration of Dimephosphon (750 mg/kg) for 14 days post-irradiation (5 Gy).
• Assessment of intestinal epithelium and splenic capsule damage.
• Metabolomic screening to analyze key metabolites.

Main Results:

• Dimephosphon showed a local radioprotective effect, mitigating injury to the intestinal epithelium and splenic capsule.
• Metabolomic analysis revealed significant increases in antioxidant metabolites like alpha-tocopherol, nicotinamide riboside, N-carbamoyl-L-aspartate, and adenylosuccinate.
• These findings indicate enhanced antioxidant protection conferred by Dimephosphon.

Conclusions:

• Dimephosphon possesses significant radioprotective properties.
• The drug enhances the body's antioxidant defense mechanisms.
• Dimephosphon shows promise as a radioprotective agent in radiation oncology.
