The Structure of M-Gtfi,An Inhibitor of Glucosyltransferase from S. Mutans,And Its Inhibitory Relationship with Other Sulfate Ester-Containing Inhibitors |
| |
Abstract: | AbstractM-GTFI, an inhibitor of glucosyltransferase from S. mutans was produced by Micromonospora narashinoensis strain No. 731. The isolation procedure for M-GTFI was improved and established for spectro-scopic analyses, and some properties of the inhibitor were investigated. The structure of M-GTFI was shown to be trisodium [2-sulphonato-9-undecenyll-oxacyclotriacont-3-en-2-one, 16, 18-his sulp-honate. The chemical structure of M-GTFI was therefore similar to that of izumenolide which is a β-lactamase inhibitor containing sulfate ester groups in its molecule.The inhibitory characteristics of M-GTFI were parallel to that of other inhibitory compounds containing sulphate esters but the spectrum of activity was wider. |
