The present invention relates to mono- or bi-functional (per)fluoropolyethers comprising a linear (per)fluoropolyether chain having two ends, wherein one or two ends contain —CF(CF
3
)COF groups, to a process for preparing them and to their use as precursors in the preparation of further functionalised (per)fluoropolyethers. The invention also relates to these further functionalised (per)fluoropolyethers.
The invention relates to the inhibition of histone deacetylase. The invention provides compounds and methods for inhibiting histone deacetylase enzymatic activity. The invention also provides compositions and methods for treating cell proliferative diseases and conditions.
3-substituted-6-aryl pyridines of Formula I are provided:

, A and Ar are defined herein. Such compounds are ligands of C5a receptors. Preferred compounds of Formula I bind to C5a receptors with high affinity and exhibit neutral antagonist or inverse agonist activity at C5a receptors. The present invention also relates to pharmaceutical compositions comprising such compounds, and to the use of such compounds in treating a variety of inflammatory, cardiovascular, and immune system disorders. In addition, the present invention provides labeled 3-substituted-6-aryl pyridines, which are useful as probes for the localization of C5a receptors.
