DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention comprises novel substituted tetronic acid type compounds, 2,4-(3H,5H)-furandiones, that are useful for the inhibition of the HIV protease enzyme. The compounds may be useful for the treatment of a person with AIDS or AIDS related diseases. The compounds may be used in the attempt to retard the further replication of any retrovirus containing the aspartyl protease enzyme.
