Design of novel CXCR4 antagonists that are potent inhibitors of T-tropic (X4) HIV-1 replication
摘要:
A novel series of CXCR4 antagonists were identified based on the substantial redesign of AMD070. These compounds possessed potent anti-HIV-1 activity and showed excellent pharmacokinetics in rat and dog. (C) 2011 Elsevier Ltd. All rights reserved.

Using AMD070 as a starting point for structural modification, a novel series of isoquinoline CXCR4 antagonists was developed. A structure-activity scan of alternate lower heterocycles led to the 3-isoquinolinyl moiety as an attractive replacement for benzimidazole. Side chain optimization in the isoquinoline series led to a number of compounds with low nanomolar anti-HIV activities and promising rat PK properties. (C) 2010 Elsevier Ltd. All rights reserved.
