Description

Novel pyrrolidine derivatives as antagonists of the Chemokine receptor

THE FIELD OF THE INVENTION

The present invention relates to new compounds, to pharmaceutical composition containing said compounds and to the use of said compounds in therapy. The present invention further relates to processes for the preparation of said compounds and to new intermediates useful in the preparation thereof.

BACKGROUND OF THE INVENTION

Chemokines play an important role in immune and inflammatory responses in various diseases and disorders, including asthma, chronic obstructive pulmonary disease (COPD), allergic diseases, rheumatoid arthritis and atherosclerosis. These small secreted molecules are a growing superfamily of 8-14 kDa proteins characterised by a conserved four cysteine motif. The chemokine superfamily can be divided into two main groups exhibiting characteristic structural motifs, the Cys-X-Cys (C-X-C) and Cys-Cys (C-C) families. These are distinguished on the basis of a single amino acid insertion between the NH- proximal pair of cysteine residues and sequence similarity.

Chemokines are attractants and activators of monocytes, lymphocytes and neutrophils. The C-C chemokines include potent chemoattractants such as human monocyte chemotactic proteins 1-3 (MCP-I, MCP-2 and MCP-3), RANTES (Regulated on Activation, Normal T Expressed and Secreted), eotaxin and the macrophage inflammatory proteins lα and lβ (MIP- lα and MIP- lβ). The C-X-C chemokines include several potent chemoattractants such as interleukin-8 (IL-8) and neutrophil-activating peptide 2 (NAP-2).

Studies have demonstrated that the actions of the chemokines are mediated by subfamilies of G protein-coupled receptors, among which are the receptors designated CCRl, CCR2, CCR2A, CCR2B, CCR3, CCR4, CCR5, CCR6, CCR7, CCR8, CCR9, CCRlO, CXCRl, CXCR2, CXCR3 and CXCR4. Chemokine Receptor 1 (CCRl) is highly expressed in tissues affected in different autoimmune, inflammatory, proliferative, hyper proliferative and immunologically mediated diseases, e.g. asthma, chronic obstructive pulmonary disease, multiple sclerosis and rheumatoid arthritis. Therefore, inhibiting CCRl -mediated events is expected to be effective in the treatment of such conditions.

International publication numbers WOO 1/98273 and WO03/051839 describe benzyl - piperidines which modulate MIP- lα chemokine receptor activity.

A desirable property for a drug acting at the CCRl receptor is that it has high potency e.g. as determined by its ability to inhibit the activity of the CCRl receptor. It is also desirable for such drugs to possess good selectivity and pharmacokinetic properties in order to further enhance drug efficacy. As an example, it can be advantageous for such drugs to possess good metabolic stability and bioavailability.

It is also desirable for compounds to exhibit low activity against the human ether-a-go-go- related-gene (hERG)-encoded potassium channel. In this regard, low activity against hERG binding in vitro is indicative of low activity in vivo.

The present inventors have identified new compounds which modulate CCRl receptor activity and which have particularly beneficial potency, selectivity and/or pharmacokinetic properties.

The compounds of formula (I) - (VI) are capable of existing in stereoisomeric forms. It will be understood that the invention encompasses the use of all geometric and optical isomers of the compounds of formula (I) - (VI) and mixtures thereof including racemates. Thus, compounds can be prepared as an enantiomeric mixture of the (3R,4R and 3S,4S)- trans-4-(piperidin-4-yl]amino)pyrrolidin-3-ol or can be separated to provide both the (3R,4R) and (3S,4S) compounds.

It will be appreciated that the compounds of formula (I) - (VI) and salts may exist as zwitterions. Thus, whilst the compounds are drawn and referred to in the neutral form, they may also exist in internal salt (zwitterionic) form. The representation of formula (I) - (VI) and the examples of the present invention covers both neutral and zwitterionic forms and mixtures thereof in all proportions.

The compounds of formula (I) - (VI) may be used in the form of a pharmaceutically acceptable salt thereof, conceivably an acid addition salt such as a hydrochloride, hydrobromide, phosphate, sulfphate, acetate, ascorbate, benzoate, 2-fluorobenzoate, 2,6- difluorobenzoate, (hemi)fumarate, furoate, succinate, maleate, tartrate, citrate, oxalate, xinafoate, methanesulphonate or/?-toluenesulphonate. Pharmaceutically acceptable salts may also be formed together with metals such as calcium, magnesium, sodium, potassium or zinc or bases such as piperazine, 2-aminoethanol, choline, diethylamine or diethanol amine. Other pharmaceutically acceptable salt may include amino acid addition salts such as L-lysine, glycine, L-glutamine, L-asparagine or L-arganine. A pharmaceutically acceptable salt also includes internal salt (zwitterionic) forms. Any reference to compounds of formula (I) - (VI) or salts thereof also encompasses solvates of such compounds and solvates of such salts (e.g. hydrates). Process

Certain intermediates that are usefull for the making of the compounds of formula (I) - (VI) of this invention may be synthesised using the procedures set out in applications WO01/98273 and PCT/SE2006/001227.

(i) converting a compound of formula (I) - (VI) obtained to a different compound of formula (I) - (VI);

(ii) removing of any protecting groups; and

(iii) forming a pharmaceutically acceptable salt and/or polymorph of the compound of formula (I) - (VI).

As will be apparent to a person skilled in the art, following the epoxide opening of intermediates like compound of formula X or XV with an amine, will produce an enantiomeric mixture of trans (3R,4R) and (3S,4S) intermediates XI, XIII, XIV and final product, which can be separated to provide both the (3R,4R) and (3S,4S) compounds.

Process (a) - (i) may conveniently be carried out in a suitable solvent, for example an organic solvent selected from alcohol such as methanol or ethanol, a hydrocarbon, cyanides such as acetonitrile or butyronitrile, ethers such as THF or dioxane, NMP, DCM or DMF at a temperature of, for example 20 0C or above, such as a temperature in the range from 25-150 0C.

In processes (c), (e) and (h) the choice of a suitable leaving group L2 would be routine for a person skilled in the art. In the event of the leaving group being a bromine atom, Buchwald conditions may be applied, reacting intermediates in the presence OfPd2(DBA)3, BINAP and sodium t-butoxide. In the event of the leaving group being a chlorine or fluoride atom, SNAΓ conditions may be applied, reacting the intermediates in the presence of an organic base, such as DIPEA or DBU. It will be appreciated by those skilled in the art that in the processes of the present invention certain functional groups such as carboxyl, hydroxyl, or amino groups in the starting reagents or intermediate compounds my need to be protected by protecting groups. Thus, the preparation of the compounds of formula (I)-(VI) may involve, at an appropriate stage, the introduction c.q. removal of one or more protecting groups.

The protection and deprotection of functional groups is described in 'Protective Groups in Organic Chemistry', edited by J.W.F. McOmie, Plenum Press (1973) and 'Protective Groups in Organic Synthesis', 3rd edition, T. W. Greene and P. G. M. Wuts, Wiley- Interscience (1999).

The compounds of formula (I) or (Ia) or a pharmaceutically acceptable salt, solvate or solvated salt thereof, as defined above may also be prepared according to the preparation routes described in schemes 1 below.
