[VESTIBULAR AND THERMOPROTECTIVE PROPERTIES OF A NEW ACTOPROTECTOR].

In experiments with rats, a new 3-hydroxypyridine (3-HP) derivative--2-ethyl-6-methyl-3-hydroxypyridine L-asparaginate (30 mg/kg)--exhibited a strong vestibuloprotective effect which was better than of promethazine (50 mg/kg), a well-known vestibuloprotector Besides the new actoprotector was competitive with another 3-HP derivative, namely, mexidol (ethyl-methyl-hydroxypyridine succinate) (100 mg/kg). Moreover, a distinct thermoprotective effect of 2-ethyl-6-methyl-3-hydroxypyridine L-asparaginate (30 mg/kg) in mice was not worse than that of mexidol or metaprot (ethylthiobenzimidasol, former name bimethy), an actoprotector with good thermoprotective properties. To conclude, owing to the membrane-protective and antioxidative qualities, the vestibuloprotective and thermoprotective properties of 2-ethyl-6-methyl-3-hydroxypyridine L-asparaginate are better or competitive with the reference preparations.
