Unmodified hydrated С fullerene molecules exhibit antioxidant properties, prevent damage to DNA and proteins induced by reactive oxygen species and protect mice against injuries caused by radiation-induced oxidative stress.

Unmodified hydrated С fullerene molecules (CUHFM) were shown to reduce the formation ROS in water and 8-oxoguanine in DNA upon ionizing radiation impact. CUHFM efficiently eliminate long-lived protein radicals arising after irradiation. In irradiated mice CUHFM reduce the rate of single/double-strand DNA breaks and amount of chromosomal breaks.
