Inactivation of S-adenosylhomocysteine hydrolase with haloethyl and dihalocyclopropyl esters derived from homoadenosine-6′-carboxylic acid
摘要:
In a search for new inhibitors that exploit 5'-6' `hydrolytic activity' of AdoHcy hydrolase, a new series of haloethyl and dihalocyclopropyl esters 2-3 were designed and their interaction with the enzyme studied. Incubation of the enzyme with 2-3 resulted in time- and concentration-dependent inactivation of AdoHcy hydrolase as well as almost total depletion of its NAD+ content. Further results indicated that the `oxidative' but not the `hydrolytic' activity was involved in the inactivation process. (C) 2004 Elsevier Ltd. All rights reserved.
