A compound of formula (I) wherein: R1 is hydrogen, halo or methoxy; R2 is hydrogen, halo, methyl, ethyl or methoxy; R3 is a halo group or a trifluoromethyl group; R4 is a halo group or a trifluoromethyl group; R5 is hydrogen or halo; R6 is hydrogen or halo; provided that when R5 and R6 are both hydrogen, and one of R3 or R4 is chloro or fluoro, then the other is not chloro or fluoro; or a pharmaceutically acceptable salt or prodrug thereof. These compounds have useful activity for the treatment of inflammatory disease, specifically in antagonising an MCP-1 mediated effect in a warm-blooded animal such as a human being.

2-Fluoro-, 4-fluoro-, and 6-fluorophenylephrine (6-FPE) were synthesized from the corresponding fluorinated 3-hydroxybenzaldehydes.New routes to 2-fluoro- and 6-fluoro-3-hydroxybenzaldehydes were developed based on regioselective lithiation of 2- and 4-fluorobenzene ortho to fluorine.As with norepinephrine and isoproterenol analogues, the adrenergic properties of phenylephrine were markedly altered by ring fluorination.The order of potency of the fluoro analogues as α1-adrenergic agonists in the stimulation of contraction of aorticstrips and of phosphatidylinositol turnover and potentiation of cyclic AMP accumulation in guinea pig synaptoneurosomes was 6-FPE > PE > 4-FPE > 2-FPE.The same pattern was observed for the displacement of radioligands specific for α1- and α2-adrenergic receptors on brain membranes.The order of potency for the displacement of 3H>dihydroalprenolol, a β-specific adrenergic ligand from brain membranes, was 2-FPE > 4-FPE = PE >> 6-FPE. 6-FPE was much more selective for α-adrenergic receptors compared to β-receptors than was phenylephrine.A rationale for the observed fluorine-induced alterations in potency and selectivity of the FPEs for α- and β-adrenergic systems is presented based on fluorine-induced conformations due to electrostatic repulsion of fluorine and the benzyl hydroxyl group.
