NO donors. Part 18: Bioactive metabolites of GTN and PETN—Synthesis and vasorelaxant properties
摘要:
The vasodilators glyceryl trinitrate (GTN) and pentaerythrityl tetranitrate (PETN) are supposed to be degraded in vivo to the lower nitrates PETriN, PEDN, PEMN, 1,2-GDN, 1,3-GDN, 1-GMN, and 2-GMN. We synthesized these bioactive metabolites as reference compounds for pharmacokinetic studies. The use of HPLC-methods for monitoring the stepwise reduction of PETN to lower nitrates and the syntheses of the glyceryl dinitrates proved advantageous. Furthermore, we measured the vasorelaxant properties of all metabolites by performing organ bath experiments with porcine pulmonary arteries. In general, the vasodilator potency increases with the number of nitrate moieties in the compound. (C) 2009 Published by Elsevier Ltd.

Additive for Cetane Number Increase of Diesel Fuels or Bio-Diesel Fuels The essence of the additive increasing the diesel or bio-diesel fuels cetane number consists in the additive constituted glycerol mono- and diesters nitrates containing the isomers of glycerol dialkyl ester mononitrate and/or isomers of glycerol monoalkyl ester dinitrate with between 1 and 20 carbons in the ester alkyl group and their addition in concentrations between 1 and 5,000 mg/kg to the total fuel amount. The additive is added either directly or diluted in fatty acids alkyl esters having from 1 to 20 carbons in the acid and/or alcohol relevant group contained in the esters.
