  Specific Inhibitors of Puromycin-Sensitive Aminopeptidase with a 3-(Halogenated Phenyl)-2,4(1H,3H)-quinazolinedione Skeleton

  摘要：

  Specific puromycin-sensitive aminopeptidase (PSA) inhibitors with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton were prepared and their structure-activity relationships were investigated. The nature (F, Cl or Br), number and position(s) of the halogen atom(s) introduced into the 3-phenyl group were concluded to be critical determinants of the inhibitory activity.

  were efficiently synthesized by selenium-catalyzed carbonylation of o-nitrobenzamides under relatively mild conditions. In situ-generated carbonyl selenide (SeCO) is proposed to initiate the catalytic carbonylation. Thus, a concise transition metal and phosgene-free synthetic route to potentially bioactive-substituted 1H-quinazoline-2,4-dione derivatives has been developed.
