Novel lopinavir analogues incorporating heterocyclic replacements of six-member cyclic urea––synthesis and structure–activity relationships
摘要:
The HIV protease inhibitor ABT-378 (lopinavir) has a six-member cyclic urea in the P-2 position. A series of analogues in which the six-member cyclic urea is replaced by various heterocycles was synthesized and the structure-activity relationships explored. (C) 2004 Elsevier Ltd.

A compound comprising a substituent of the formula (II) is disclosed as an HIV protease inhibitor. Intermediates for making such compounds and processes for making such intermediates are also disclosed.

The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side-effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.
