Enzymatic Activation of Hydrazine Derivatives
The oxidative metabolism of hydralazine, isoniazid, iproniazid, and phenylhydrazine has been studied using spin-trapping techniques. The oxidation of these hydrazine derivatives, catalyzed by horseradish peroxidase and prostaglandin synthetase, produces reactive free radical intermediates. Enzymatic activation of hydralazine produce the nitrogen-centered hydralazyl radical (RNHNH.); phenylhydra...
متن کاملFree radical-mediated activation of hydrazine derivatives.
Hydrazines are known to undergo oxidative activation in several enzymatic systems in vitro. Free radicals or carbonium ions have been proposed as active intermediates during such activation. The toxic effects elicited by hydrazines have also been linked to free radical-mediated activation. In this report, we have reviewed the identification of organic free radicals from hydrazines by direct ESR...
متن کاملSynthesis and analgesic activity of novel Hydrazide and Hydrazine derivatives
The uses of non-steroidal anti-inflammatory drugs (NSAIDs) are limited by a variety of side effects. So research on preparing new analgesic agents is important. According to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. The final compounds 10a-10e and 15a-15d were pre...

متن کاملEfficient methodology for selective alkylation of hydrazine derivatives.
Formation and use of a nitrogen dianion for selective hydrazine alkylation is reported. The scope and limitations of a new method were demonstrated. The novel method provides fast and easy access to substituted hydrazines, which are widely used as drugs, pesticides, and precursors for a variety of compounds in organic synthesis.
