Abstract

The present invention relates to respiratory formulations comprising a compound of formula (I):

and use of said compounds and compositions in treatment, for example in the treatment of an inflammatory disease or a respiratory disorder, in particular an inflammatory mediated and/or virally mediated respiratory disorder such as asthma and COPD or the treatment or prevention of viral infection, for example infection by influenza virus, rhinovirus or RSV. The invention also extends to certain novel compounds of formula (I).

First claim

The invention claimed is:

1. An inhaler device comprising a formulation of compound of formula (I):

J represents:

Q is N or —CH—;
X is O or O—CH 2 —;
Y is —CH═ or N;
Z is O, NR 4 , —CR 4a ═N— or —N═CR 4a — whereby the latter two groups, together with the atoms to which they are attached, form a 6 membered ring;
R 1 is C 1-6 alkyl, branched or unbranched, or C 3-6 cycloalkyl, each optionally substituted by a hydroxyl group;
R 2a is H, halo, saturated or unsaturated branched or unbranched C 1-8 alkylene chain, wherein one or more carbons are optionally replaced by a heteroatom(s) independently selected from —O—, —N— and/or S(O) m and the chain is optionally substituted by one or more halogen atoms;
R 2b is H, halo, C 1-6 alkoxy or C 1-6 alkyl optionally substituted by OH;
R 2 and R 3 each independently represent H, C 1-4 alkyl, halogen; C 1-4 haloalkyl, O(C 1-4 alkyl), O(C 1-4 haloalkyl), CN, SO 2 R 5 , C(O)OR 6 with the proviso that R 2 and R 3 do not both represent H concomitantly, or
R 2 and R 3 together with the carbons to which they are attached form a six membered aromatic ring or a heteroaromatic ring comprising a nitrogen atom;
R 4 is H, C 1-5 alkyl, C 2-5 alkenyl, C 2-5 alkynyl, C 3-6 cycloalkyl, C 3-6 cycloalkenyl, C 6 aryl, a 5 or 6 membered heteroaryl or a 5 or 6 membered heterocyclic group, wherein said aryl, heteroaryl or heterocyclic group is substituted with 0 to 3 substituents selected from halogen, hydroxyl, C 1-6 alkyl, C 1-6 alkoxy, C 1-6 haloalkyl, amino, C 1-4 mono or di-alkyl amino, C 1-4 mono or di-acyl amino, S(O) q C 1-6 alkyl, C 0-6 alkylC(O)C 1-6 alkyl or C 0-6 alkylC(O)C 1-6 heteroalkyl;
R 4a is H or C 1-3 alkyl;
R 5 is H or C 1-4 alkyl;
R 6 is H or C 1-4 alkyl;
m is 0, 1 or 2;
q is 0, 1 or 2;
a pharmaceutically acceptable salt thereof, including all stereoisomers, tautomers and isotopic derivatives thereof in particulate form, wherein the mass mean aerodynamic diameter (MMAD) of the population of particles is in the range 1 to 20 microns.
