 AB    HIV encodes a novel aspartyl protease that represents an important
       virus-specific target for inhibitors. We have been studying a series of
       transition state analogue inhibitors designed and synthesised in
       Australia that have potent and specific activity against HIV replication
       in cell culture. (Note: the structure of these compounds will not be
       presented). The inhibitors are active against HIV-1 and HIV-2 in acutely
       and chronically infected cells, working through a mechanism involving
       inhibition of cleavage of p55 to its structural components. As a result,
       virions produced in the presence of these drugs are noninfectious. The
       inhibitors are also active against AZT-resistant HIV and the simian
       immunodeficiency virus, but fail to inhibit feline immunodeficiency
       virus. These results will be presented, along with preliminary details
       on the pharmacokinetics of selected inhibitors.
