  Structure−Activity Relationships of N-Hydroxyurea 5-Lipoxygenase Inhibitors

  摘要：

  The discovery of second generation N-hydroxyurea 5-lipoxygenase inhibitors was accomplished through the development of a broad structure-activity relationship (SAR) study. This study identified requirements for improving potency and also extending duration by limiting metabolism. Potency could be maintained by the incorporation of heterocyclic templates substituted with selected lipophilic substituents. Duration of inhibition after oral administration was optimized by identification of structural features in the proximity of the N-hydroxyurea which correlated to low in vitro glucuronidation rates. Furthermore, the rate of in vitro glucuronidation was shown to be stereoselective for certain analogs. (R)-N-[3-[5-(4-Fluorophenoxy)-2-furyl]-1-methyl-2-propynyl]-N-hy- droxyurea (17c) was identified and selected for clinical development.

  日期：2001.1

  A highly efficient synthesis of Zileuton is described in which the key step involves a site-specific alkylation of hydroxyurea under acid catalysis. Various aryl alcohol electrophiles were tested and the reaction was found to be highly substrate-specific, favoring benzothiophene and benzofuran-based alcohols.
