Carrageenans as new substances for drugs with radioprotective effect

Carrageenans - the natural polysaccharides received from red seaweed. One of their major biological properties is ability to connect ions of metals. This property allows to consider carrageenans as a basis for development drugs with radioprotective effect. Metals connecting activity of various types of carrageenans was studied in the systems containing ions of strontium or cerium. By results of experiment it is established that k-and i-carrageenans effectively connect ions of strontium and cerium, thus the greatest activity was observed at i-carrageenan.
