Abstract

Small-molecule peptidomimetic inhibitors that already showed activity towards Secreted aspartic protease 2 as anti-Candida agents are herein presented as candidate HIV protease inhibitors. A library of 6,8-dioxa-3-azabicyclo[3.2.1]-octane peptidomimetic scaffolds was screened towards HIV protease, resulting in the identification of hit compounds possessing IC50 in the sub-micromolar range, and showing the bicyclic acetal portion as a potential transition state analogue in the interaction with catalytic aspartic acid residues.
