AB With the goal of obtaining inexpensive yet potent anti-AIDS drugs,
simple inhibitors of HIV-1 protease were synthesised. The C2-symmetrical
pseudopeptidic substrate analogues can be prepared as inhibitors for
HIV-1 protease starting from symmetrical ketones 3a-d by a facile
four-step synthesis. After bromination of 3a-d to
alpha,alpha'-dibromoketones 4a-d, we synthesised the diamino compounds
6a-c by Gabriel synthesis, which were then coupled with Z-valine to
yield inhibitors including a central hydroxy group 8a-d a-i by
azidation, reduction with LiAlH4 and coupling of the
beta,beta'-diaminohydroxy compounds with appropriate peptides. The first
set of compounds showed only weak inhibition whereas the latter reach Ki
values of up to 3.0 microM.
