The only substrates which appeared to resist enzymatic denitration totally were PE mononitrate and PE mononitrate glucuronide. The susceptibility of the other substrates decreased in the sequence: PE trinitrate > PE dinitrate, PE trinitrate glucuronide > PE dinitrate glucuronide. PE and its mono-, di-, and trinitrates were tested for ability to undergo glucuronidation by rat liver microsomes and uridine diphosphate glucuronic acid. The three PE nitrates were comparably amenable to glucuronidation, but PE did not undergo this conjugation. Copyright © 1974 by The American Society for Pharmacology and Experimental Therapeutics ER -
