L. CASEI THYMIDYLATE SYNTHASE WITH SPECIES SPECIFIC INHIBITOR
OverviewOverview
Thymidylate synthase is an attractive target for antiproliferative drug, design because of its key role in the synthesis of DNA. As such, the, enzyme has been widely targeted for anticancer applications. In principle, TS should also be a good target for drugs used to fight infectious, disease. In practice, TS is highly conserved across species, and it has, proven to be difficult to develop inhibitors that are selective for, microbial TS enzymes over the human enzyme. Using the structure of TS from, Lactobacillus casei in complex with the nonsubstrate analogue, phenolphthalein, inhibitors were designed to take advantage of features of, the bacterial enzyme that differ from those of the human enzyme. Upon, synthesis and testing, these inhibitors were found to be up to 40-fold, selective for ... [(full description)]
