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.
The present invention relates to compounds that bind to chemokine receptors, and having the formula

are substituents. The present invention also relates to methods of using such compounds, such as in treating HIV infection and inflammatory conditions such as rheumatoid arthritis. Furthermore, the present invention relates to methods to elevate progenitor and stem cell counts, as well as methods to elevate white blood cell counts, using such compounds.
A protocol for highly enantioselectivehydrogenation of racemic α-arylamino lactones with catalysis by site-specifically modified chiral spiro iridium complexes has been developed. With the optimized catalyst, racemic α-arylamino-γ-lactones and α-arylamino-δ-lactones could be hydrogenated to the corresponding chiral 2-amino diols with good to excellent enantioselectivities.
