Recent research suggests that NO may play a role in the physiological effects of some guanidine-containing drugs. In this guanethidine together with their N-hydroxyl derivatives were report, three guanidine-containing drugs (guanadrel, guanoxan, and guanethidine) together with their N-hydroxyl derivatives were synthesized and their NO-releasing abilities catalyzed by nitric oxide synthases (NOSs) and horseradish peroxidase were evaluated. The guanidine containing compounds could not release NO in the presence of NOS or peroxidase. The corresponding N-hydroxyl compounds exhibited Weak NO-releasing ability under the catalyzed of NOS and good NO-releasing ability tinder the oxidation by horseradish peroxidase in the presence of H2O2. These compounds also displayed vasodilatory activity. (C) 2001 Elsevier Science Ltd. All rights reserved.
