Description

PHARMACEUTICAL USE

The present invention relates to the use of unsaturated quinoline or naphthalene derivatives as medicaments (for example in the treatment of an inflammatory disease state), to a method of using such derivatives and to pharmaceutical compositions comprising such derivatives.

Hydroquinoline derivatives are disclosed in EP-A1-0347960. 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, US6323199). 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.

The present invention provides a compound of formula (I):

wherein:

T is CH or N; W, X, Y and Z are, independently, hydrogen, halo, C_1-4 alkyl, C_1-4 alkoxy, C_1-4 alkylthio, CF₃,

OCF₃, benzyloxy, nitro, cyano, S(O)₂NH₂, C(O)(C_1-4 alkyl), C(O)NH₂, NHC(O)(C_1-4 alkyl) or

NR¹⁰R¹¹; and W and X and/or Y and Z may join to form a fused benzene or pyridine ring;

R¹⁰ and R¹¹ are, independently hydrogen, C_1-4 alkyl or C_3-7 cycloalkyl;

R¹, R² and R³ are, independently, hydrogen or C_1-4 alkyl; L is CH₂ or C(O); the bond A is a single or a double bond; or a pharmaceutically acceptable salt thereof; for use as a medicament.

Compounds of of formula (I) can exist in different isomeric forms (such as enantiomers, diastereomers, geometric isomers or tautomers). The present invention covers the use of all such isomers, and the use of all mixtures of isomers in all proportions. Suitable salts include acid addition salts such as a hydrochloride, hydrobromide, phosphate, acetate, fumarate, maleate, tartrate, citrate, oxalate, methanesulphonate,/*- toluenesulphonate, succinate, glutarate or malonate.

The compounds of formula (I) may exist as solvates (such as hydrates) and the present invention covers the use of all such solvates. Alkyl groups and moieties are straight or branched chain and are, for example, methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl or tert-butyl.

Cycloalkyl is for example, cyclopropyl, cyclopentyl or cyclohexyl.

In one particular aspect the present invention provides a compound of formula (I) wherein: W and X are both hydrogen; Y and Z are, independently, hydrogen or halo (such as fluoro or chloro); R¹, R² and R³ are, independently, C_1-4 alkyl; L is CH₂ or C(O); the bond A is a single or a double bond; or a pharmaceutically acceptable salt thereof; for use as a medicament.

The compounds of formula (I) can be prepared using or adapting methods disclosed in the art. Starting materials for the preparative methods are either commercially available or can be prepared by literature methods, adapting literature methods.

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.
