Authors

Authors investigated the scavenger capability of lazaroids, a new group of compounds (21-aminosteroid) that are reported in the literature to have interesting anti-lipid peroxidation properties. Authors tested the degree of scavenger activity related to the oxygen derived free radicals (ODFR) with different methods: 1) chemiluminescence; 2) production of superoxide anion from activated polymorphonuclear cells; 3) production of hydroxyl radical through a chemical procedure. Results showed a global scavenger activity of the three lazaroids (U78517F, U74389F, U74500A) in all the various tests, but differences of intensity of their action were noted among in each compound. We can thus attribute to these compounds a scavenger activity on the oxygen free radicals; this activity may facilitate their already known anti-lipid peroxidation action. Therefore, clinical use of lazaroids can be hypothesized for the diseases in which inflammation plays an important pathogenetic role via the production of oxygen free radicals and the resulting lipid peroxidation associated with tissue damage.
