2‘,6‘-Dimethylphenoxyacetyl: A New Achiral High Affinity P3-P2 Ligand for Peptidomimetic-Based HIV Protease Inhibitors
摘要:
Starting from palinavir (1), our lead HIV protease inhibitor, we have discovered a new series of truncated analogues in which the P-3-P-2 quinaldic-valine portion of 1 was replaced by 2',6'-dimethylphenoxyacetyl. With EC50's in the 1-2 nM range, some of these compounds are among the most potent inhibitors of HIV replication in vitro, reported to date. One of the most promising members in this series (compound 27, BILA 2185 BS) exhibited a favorable overall pharmacokinetic profile, with 61% apparent oral bioavailability in rat. X-ray crystal structures and molecular modeling were used to rationalize the high potency resulting from incorporation of this structurally simple, achiral ligand into the P-3-P-2 position of hydroxyethylamine-based HIV protease inhibitors.
The present invention relates to a compound of formula (I), and to pharmaceutical compositions containing said compound and to the use of said compound in therapy, for instance in treating cognitive disorders, as well as to intermediates useful in the preparation thereof.

The HIV protease inhibitor ABT-378 (Lopinavir) has a 2,6-dimethylphenoxyacetyl group in the P-2' position. Analogues in which this group is replaced with various substituted phenyl or heteroaryl groups were synthesized and the Structure-activity relationships explored. (C) 2002 Elsevier Science Ltd.
