A method of inhibiting or effecting the activity of protein kinase activity which comprises contacting a protein kinase with a compound of formula (I) being a derivative of a furanose or pyranose form of a monosaccharide, or a pharmaceutically acceptable salt thereof.

Treatment of the readily available di-N-oxide- of 2-thiopyridine disulfide 6 with tributylphosphine in the presence of a carboxylic acid provides a convenient and high yielding synthesis of the acyl derivatives 2 of N-hydroxy-2-thio-pyridone. Application of this procedure to the acids 17 and 18 gave, after irradiation in the presence of t-butylthiol, the desired decarboxylated derivatives in high (>90%)

Photolysis of N-hydroxy-2-thiopyridone esters derived from uronic acids or α-amino acids in presence of vinyl phosphonate affords the corresponding phosphonate derivatives. A convenient route for the synthesis of the isostere of AZT-5′ monophosphate is described.
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.
