Abstract
Compounds of formula (I) or a pharmaceutically acceptable salt thereof; compositions comprising them, processes for preparing them and their use in medical therapy (for example modulating the glucocorticoid receptor in a warm blooded animal).
Description

The present invention relates to sulphonamide derivatives, to their use as medicaments (for example in the treatment of an inflammatory disease state), to pharmaceutical compositions comprising them and to processes for preparing them.


Sulphonamide derivatives are disclosed as anti-inflammatories in WO 2004/019935 and WO 2004/050631. Pharmaceutically active sulphonamides are also disclosed in Arch. Pharm. (1980) 313 166-173, J. Med. Chem. (2003) 46 64-73, J. Med. Chem. (1997) 40 996-1004, EP 0031954, EP 1190710 (WO 200124786), U.S. Pat. No. 5,861,401, U.S. Pat. No. 4,948,809, U.S. Pat. No. 3,992,441 and WO 99/33786.


It is known that certain non-steroidal compounds interact with the glucocorticoid receptor (GR) and, as a result of this interaction, produce a suppression of inflammation (see, for example, U.S. Pat. No. 6,323,199). Such compounds can show a clear dissociation between anti-inflammatory and metabolic actions making them superior to earlier reported steroidal and non-steroidal glucocorticoids. The present invention provides further non-steroidal compounds as modulators (for example agonists, antagonists, partial agonists or partial antagonists) of the glucocorticoid receptor capable of having a dissociation between their anti-inflammatory and metabolic actions.

As used herein the term “congestive heart failure” (CHF) or “congestive heart disease” refers to a disease state of the cardiovascular system whereby the heart is unable to efficiently pump an adequate volume of blood to meet the requirements of the body's tissues and organ systems. Typically, CHF is characterized by left ventricular failure (systolic dysfunction) and fluid accumulation in the lungs, with the underlying cause being attributed to one or more heart or cardiovascular disease states including coronary artery disease, myocardial infarction, hypertension, diabetes, valvular heart disease, and cardiomyopathy. The term “diastolic congestive heart failure” refers to a state of CHF characterized by impairment in the ability of the heart to properly relax and fill with blood. Conversely, the term “systolic congestive heart failure” refers to a state of CHF characterized by impairment in the ability of the heart to properly contract and eject blood.


As will be appreciated by one of skill in the art, physiological disorders may present as a “chronic” condition, or an “acute” episode. The term “chronic”, as used herein, means a condition of slow progress and long continuance. As such, a chronic condition is treated when it is diagnosed and treatment continued throughout the course of the disease. Conversely, the term “acute” means an exacerbated event or attack, of short course, followed by a period of remission. Thus, the treatment of physiological disorders contemplates both acute events and chronic conditions. In an acute event, compound is administered at the onset of symptoms and discontinued when the symptoms disappear.

A pharmaceutical composition of the present invention can be administered in a standard manner for the disease condition that it is desired to treat, for example by topical (such as to the lung and/or airways or to the skin), oral, rectal or parenteral administration. Thus, a the compound of formula (I), or a pharmaceutically acceptable salt thereof, may be formulated into the form of, for example, an aerosol, a powder (for example dry or dispersible), a tablet, a capsule, a syrup, a granule, an aqueous or oily solution or suspension, an (lipid) emulsion, a suppository, an ointment, a cream, drops, or a sterile injectable aqueous or oily solution or suspension.

EXAMPLE 195
Human Glucocorticoid Receptor (GR) Assay

The assay is based on a commercial kit from Panvera/Invitrogen (Part number P2893). The assay technology is fluorescence polarization. The kit utilises recombinant human GR (Panvera, Part number P2812), a Fluoromone™ labelled tracer (GS Red, Panvera, Part number P2894) and a Stabilizing Peptide 10X (Panvera, Part number P2815). The GR and Stabilizing Peptide reagents are stored at −70° C. while the GS Red is stored at −20° C. Also included in the kit are 1M DTT (Panvera, Part number P2325, stored at −20° C.) and GR Screening buffer 10X (Panvera, Part number P2814, stored at −70° C. initially but once thawed stored at room temperature). Avoid repeated freeze/thaws for all reagents. The GR Screening buffer 10X comprises 100 mM potassium phosphate, 200 mM sodium molybdate, 1 mM EDTA and 20% DMSO.


Test compounds (1 μL) and controls (1 μL) in 100% DMSO were added to black polystyrene 384-well plates (Greiner low volume black flat-bottom, part number 784076). % control was 100% DMSO and 100% control was 10 μM Dexamethasone. Background solution (8 μL; assay buffer 10X, Stabilizing Peptide, DTT and ice cold MQ water) was added to the background wells. GS Red solution (7 μL; assay buffer 10X, Stabilizing Peptide, DTT, GS Red and ice cold water) was added to all wells except background wells. GR solution (7 μL; assay buffer 10X, Stabilizing Peptide, DTT, GR and ice cold water) was added to all wells. The plate was sealed and incubated in a dark at room temperature for 2 hours. The plate was read in an Analyst plate reader (LJL Biosystems/Molecular Devices Corporation) or other similar plate reader capable of recording fluorescence polarization (excitation wavelength 530 nm, emission wavelength 590 nM and a dichroic mirror at 561 nm). The IC50 values were calculated using XLfit model 205.
