Synthesis and SAR of novel CXCR4 antagonists that are potent inhibitors of T tropic (X4) HIV-1 replication
摘要:
An early lead from the AMD070 program was optimized and a structure-activity relationship was developed for a novel series of heterocyclic containing compounds. Potent CXCR4 antagonists were identified based on anti-HIV-1 activity and Ca(2+) flux inhibition that displayed good pharmacokinetics in rat and dog. (C) 2010 Elsevier Ltd. All rights reserved.
Methods to elevate progenitor and stem cell counts in animal subjects using compounds which bind to the chemokine receptor CXCR4 are disclosed. Preferred embodiments of such compounds are of the formula
Z-linker-Z′ (1)
or pharmaceutically acceptable salt thereof
wherein Z is of the formula
wherein A comprises a monocyclic or bicyclic fused ring system containing at least one N and B is H or an organic moiety of 1-20 atoms, Z′ is of the formula
—Ar(Y)
j
;
wherein Ar is an aromatic or heteroaromatic moiety, and each Y is independently a non-interfering substituent and j is 0-3; and “linker” represents a bond, alkylene (1-6C) or may comprise aryl, fused aryl, oxygen atoms contained in an alkylene chain, or may contain keto groups or nitrogen or sulfur atoms.
Compounds which modulate chemokine receptor activities are disclosed. These compounds are preferably tertiary amines comprising tetrahydroquinoline and benzimidazole.
