  Development of Orally Active Nonpeptidic Inhibitors of Human Neutrophil Elastase

  摘要：

  5-Amino-2-phenylpyrimidin-6-ones, some of their desamino derivatives, and miscellaneous derivatives were synthesized and biologically evaluated on both in vitro activity and oral activity in an acute hemorrhagic assay. These compounds contained an alpha -keto-1,3,4-oxadiazole moiety to bind covalently to the Ser-195 hydroxy group of human neutrophil elastase (HNE). Among those tested, compounds 11a-c,e,i-1(F), 11d,e,k(H), ald,e,k(F), and ald,e(H) showed a good oral profile. RS-Mixture 3(H) was selected for clinical evaluation based on its oral potency, duration of action, enzyme selectivity, safety profile, and ease of synthesis. Structure-activity relationships (SARs) are discussed.

  Transition-Metal-Free Oxidative Iodination of 1,3,4-Oxadiazoles

  摘要：

  AbstractTransition‐metal‐free oxidative iodination of 2‐substituted 1,3,4‐oxadiazoles was achieved by using sodium iodide as the halide source and Selectfluor as the oxidant. Variously substituted products were obtained in moderate to good yields under operationally straightforward conditions. Compared to existing methods for analogous conversions, the newly developed protocol appears synthetically attractive.
