Abstract
The treatment of HIV and AIDS was revolutionized by the introduction of peptidomimetic
aspartyl protease inhibitors. One of the major limitations of this type of therapy
is that higher therapeutic doses are necessary because of the presence of ‘peptide-like’
features in the drugs. Therefore, adequate supplies and cost effective syntheses of
these drugs are of utmost importance. To date, there are six protease inhibitors approved
by the United States Food and Drug Administration (FDA) for the treatment of HIV and
AIDS. This review focuses on the published syntheses of currently FDA approved HIV
protease inhibitor drugs, their isosteres and ligands.
