Increased antiviral activity of cyclic urea HIV protease inhibitors by modifying the P1/P1′ substituents
摘要:
A series of alkyl substituted P1/P1' analogs was prepared in an attempt to increase translation of the 3-aminoindazole class of HIV protease inhibitors. Increasing the lipophilicity of the P1/P1' residues dramatically improved translation of enzyme activity to antiviral activity in the whole cell assay. (C) 1999 Published by Elsevier Science Ltd.

Cyclicureas containing 3-aminoindazole P2/P2' groups are extremely potentinhibitors of HIVprotease. The parent 3-aminoindazole 6 showed a Ki < 0.01 nM but poor translation of enzyme activity to antiviral activity was observed. A series of 3-alkylaminoindazoles revealed that translation improved with increasing lipophilicity. An X-ray crystal structure of 6 bound to HIVprotease was obtained.
