Abstract

3-Aminopyridine derivatives of formula 1, wherein W is a group of general formula 2 or general formula 3, are inhibitors of T-cell proliferation and protein farnesyl transferase. They are useful as pharmaceutical agents for the treatment of inflammatory and malignant diseases.

Description

r 1 1 2323842
BACKGROUND
The immune response is essential for the defense of the body against invading pathogens. However, an inappropriate activation of the immune system has been implicated in the etiology of some serious disease states. These are characterised by progressive tissue damage with inflammation and invasion of the lesion by leukocytes. Examples of such diseases include inflammatory bowel disease, asthma, psoriasis and rheumatoid arthritis. Current therapeutic regimens for these conditions are often inadequate, and new approaches are required. One aspect of-the present invention is a series of compounds that inhibit the proliferation of T lymphocytes. Because T lymphocytes play a central role in the immune response it is reasonable to suppose that such compounds will prove to be of value in the treatment of irnmunoinflammatory conditions.
Another property exhibited by the compounds of the present invention is the ability to inhibit the enzyme farnesyl protein transferase (EC 2.5.1 p21RAs farnesyl transferase; Mase). Inhibitors of this enzyme have shown promise as agents for the treatment of rumours, particularly those which express variants of the oncogenic protein ras that are constituitively active. Therefore a second use for the compounds of this invention is the treatment of neoplastic: diseases.

The compounds of general formula 1 have at least one stereogenic centre and so can exist as stereoisomers (enantiomers and diastereomers). These isomers, as single compounds or as mixtures, are included within the scope of this invention. The compounds also have at least one basic site and so can form salts with acids. These 3 salts, and particularly those salts formed by pharmaceutically acceptable acids (including, but not limited to, acetic acid, citric acid, lactic acid, tartaric acid, hydrochloric acid, sulphuric acid, trifluoroacetic acid) are also included in the scope of the invention. Certain embodiments of general formula I also include acidic sites.
Ilese compounds can form s?lts with bases. Again, these salts (for example the sodium, potassium and ammonium salts) are included within the scope of the invention.
A prefered embodiment of the invention is a compound of formula 1 in which R' is an optionally substituted phenyl group, X is a covalent bond and Y is an oxygen atom, all the other groups being as defined above.
A most prefered embodiment of the invention is a compound selected from:

Such formulations will have as other ingredients 22 such materials as bulking and binding agents and preservatives as are well known in the art. Ibe formulation may be a tablet solution, suspension, cream, suppository or any other form appropriate for the administratiod of the active principal. The administration can be topical, by intravenous, subcutaneous or intramuscular injection, or via the oral, nasal, bucal, rectal or vaginal routes.
The invention includes equally the use of these formulations for the treatment of a pathological condition in a human or other mammal, wherein the pathological condition is either an inflammatory or autoimmune disease such as (but not limited to) ulcerative colitis, Crohn's disease, allergic rhinitis, graft-vs-host disease, conjuncdAtis, asthma, rheumatoid arthritis, osteoarthritis, ARDS, Behcet's disease, transplant rejection, uticaria, allergic dermatitis, allopecia areata, scleroderma, exanthem, eczema, dermatomyositis, acne, diabetes, systemic lupus erythematosis, Kawasaki's disease, multiple sclerosis, emphysema, cystic fibrosis, chronic bronchitis or psoriasis, or a proliferative disease such as cancer, for example colon, prostate or mammary carcinoma or leukaemia, or neurofibromatosis.
When used to treat these conditions the amount of formulation (and hence the amount of active principal) will be chosen by the treating physician taking into account the age, weight and state of health of the patient as well as any other factors he considers to be relevant. The amount of active principal used will generally be between 0.1mg and 10g per day in a single dose or in divided doses. Preferably the amount will be between 1mg and lg.
The general methods for the synthesis of the compounds of the invention is outlined below. For simplicity, the structural formulae show the case where p=1. The analogues in which p=2 can be prepared in the same way but starting with the appropriate homocysteine derivative in place of cysteine.
The compounds of general formula 1 are prepared from a precursor (formula 4) in which the potentially reactive amino (NH2) and mercapto (SH) groups are masked. Suitable masking groups are well Imown to practitioners of the art- Conveniently, the amino group is protected as its tert-butyl carbamate (BOC) derivative and the 23 mercapto group is protected as its triphenylmethyl (trityl) thioether. In this case both protecting groups can be removed by treating the compound with a strong acid (for example trifluoroacetic acid) in a solvent such as dichloromethane in the presence of a cation scavenger such as triethylsilane.

For example, W may include a carboxylic acid f1mcdonal group or a second amine. Either of these would lead to a mixture of products arising from competition between altemative reaction centres. In these cases 24 it will be necessary to use an amine H-W' in which the competing functional group is modified. Such a modification will generally involve the use of a protecting group, and it will often be most convenient if the protecitmig group is cleaved under the same conditions as are used to effect the final deprotetion (formula 4 -+ formula 1). Ocasionally it may be preferable to deprotect W' in a separate operation. The choice of protection strategy for W' will reflect these considerations.
The acid of formula 5 is generally prepared from a suitable ester (formula 6). Conveniently, this will, be a lower allV1 ester such as the methyl or ethyl ester. In this case the acid is released by allcaline hydrolysis using, for example, lithium hydroxide in a mixed waterldioxan solvent systern.

When X is a heteroatom, (oxygen, nitrogen or sulphur) the second component in the reaction is R'XR and the reaction requires a basic catalyst such as potassium fluoride or sodium carbonate. When X is CH2 or a covalent bond then the reaction is best achieved by a Suzuki coupling. This involves the reaction of the chloropyridine with a boronic acid R'XB(OH)-2(or a boronate ester) in the presence of a palladium catalyst.

Otherwise they can be prepared by methods analogous to those described for si compounds.
A variation of this pyridone route starts with a pyridonenitrile of formula 17. For some combinations of R' and X, the nitrile may be more accessible than the nitropyridine. The nitrile can be hydrolysed to the corresponding acid (formula 18) in the presence of strong acids. Ile acid is then subjected to a Curtius rearrangement 29 using diphenylphosphoryl azide and benzyl alcohol to give a protected an- linopyridine of formula 19.

When this is incompatible with the chemistry necessary for the further elaboration of this intermediate to the target compound a different alcohol may be used. The resulting carbamate will be chosen to have the appropriate compatibility with the conditions to be used and to require deprotection conditions which will be compatible with the functionality present when the amine is liberated.
This pyridone can then be allcylated as described above with the fragment of formula 16 to give the pyridine of formula 20.
