The inhibition of ribonuclease Bi by 3'-N-hydroxyurea-3'-deoxythymidine 5'-phosphate is enhanced by 30-fold in the presence of Zn2+. Thus, an N-hydroxyurea nucleotide can recruit Zn2+ to inhibit the enzymatic activity of a ribonuclease. This result engenders a general strategy for the inhibition of non-metalloenzymes by metal complexes. (C) 2002 Elsevier Science Ltd. All rights reserved.

Synthesis of 3′-BODIPY-Labeled Active Esters of Nucleotides and a Chemical Primer Extension Assay on Beads
A solution-phase synthesis of activeesters of 3′-fluorophore-labeled deoxynucleoside 5′-monophosphates was developed for thymine and cytosine as nucleobases by using two different BODIPY dyes. Starting from the respective 2′-amino-2′,3′-dideoxynucleoside-5′-monophosphate, the fluorescent oxyazabenzotriazolides can be prepared in one-pot procedures involving labeling and activation.
