[Electrochemical reduction of pentaerythrityltetranitrate (PETN) and metabolites]
Abstract:
The reduction-cascade of PETN is described as a combination of cyclic-voltammetric measurements and analytical results together with synthesis of PETN-metabolites; furthermore the electroreduction of pentaerythityldinitrate (PEDN) in the presence and absence of cystine as well as cystine and electrogenerated superoxide-radicalanions to elucidate the interaction of PETN with thiol-species. PETN was recognized as precursor for a initial radicalic process, followed by intermediate formation of pentaerythityltrinitratealdehyde (PENA) inside a self-reducing nitrate-system with NO as final product, which may explain its special position in comparison with other pharmaceutically applied nitratestructures. It could be proved, that a cystine-pool reacts as a selective moderator inside the reduction of PEDN without being interfered by O2.-, yielding pentaerythitylmononitrate (PEMN) meanwhile in the absence of cystine only pentaerythrite (PE) is formed.

As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
