== Publication Abstract from PubMed == | |||
Analysis of the recently solved X-ray crystal structures of Saccharomyces cerevisiae ribonucleotide reductase I (ScRnr1) in complex with effectors and substrates led to the discovery of a conserved water molecule located at the active site that interacted with the 2'-hydroxy group of the nucleoside ribose. In this study 2'-(2-hydroxyethyl)-2'-deoxyadenosine 1 and the 5'-diphosphate derivative 2 were designed and synthesized to see if the conserved water molecule could be displaced by a hydroxymethylene group, to generate novel RNR inhibitors as potential antitumor agents. Herein we report the synthesis of analogues 1 and 2, and the co-crystal structure of adenosine diphosphate analogue 2 bound to ScRnr1, which shows the conserved water molecule is displaced as hypothesized. | |||
