Sulfonated amino acid derivatives and metalloproteinase inhibitors containing the same

TECHNICAL FIELD

This application relates to sulfonated amino acid derivatives and metalloproteinase inhibitors containing the same.

BACKGROUND ART

An extracellular matrix consists of collagen, proteoglycan, etc., has a function to support tissues, and plays a role in a maintaining of a cell functions, for example propagation, differentiation, adhesion, or the like. Matrix metalloproteinases (MMP) such as gelatinase, stromelysin, collagenase, and the like have an important role in degradation of an extracellular matrix, and these enzymes work for growth, tissue remodeling, etc. under physiological conditions. Therefore, it is considered that these enzymes participate in progression of various kind of diseases involving breakdown and fibrosis of tissues, such as osteoarthritis, rheumatoid arthritis, corneal ulceration, periodontitis, metastasis and invasion of tumor, and virus infection (for example, HIV infection). At the present time, it is not clear which enzyme participates in the above diseases seriously, but it is considered that these enzymes at least participate in tissue breakdown. As metalloproteinase inhibitors of amino acid derivatives, for example hydroxamic acid derivatives of amino acids (JP-A-6-2562939), carboxylic acid derivatives of amino acid and/or their hydroxamic acid derivatives (W095135276), etc. are disclosed.

DISCLOSURE OF INVENTION

If it is able to inhibit the activity of MMP, it is considered that MMP inhibitors contribute to an improvement and prevention of the above diseases caused by or related to its activity. Therefore, development of MMP inhibitors has long been desired.

In the above situation, the inventors of the present invention found that a kind of sulfonamide derivatives have strong activity to inhibit MMP.

The present invention relates to a composition for inhibiting metalloproteinase which contains a compound of the formula I:

Conversion of compound (XV) to compound (Ia-1) is sulfonation of an amino group of the compound (XV) (process 1). If necessary, after this reaction, N-alkylation, deprotection of a carboxyl protective group, etc. are carried out. Conversion of compound (Ia-1) to compound (Ib-1) is to obtain hydroxamic acid derivatives from carboxylic acid derivatives (process 2). To obtain compound (Ib-1) from compound (Ia-1), compound (Ia-1) may also be reacted with hydroxylamine having a hydroxyl protective group or its acidic salts to give compound (XVI) (process 3), followed by and deprotection (process 4). Conversion to sulfonyl derivatives and hydroxamic acid derivatives are able to be carried out according to an usual method.

(Process 1)

Some of amino acids represented by the formula (XV) or its acidic salts (e.g., hydrochloride, p-toluenesulfonate, and trifluoroacetate) which are starting materials are commercially available. The other are able to be synthesized in accordance with a method described in Zikkenkagakukoza, vol. 22, IV (nihonkagakukai), J. Med. Chem. 38, 1689-1700, 1995, Gary M. Ksander et. al., etc. some of sulfonating agents are commercially available and the other are synthesized in accordance with a method described Shin-zikkenkagakukoza, vol. 14, 1787, 1978, Synthesis 852-854, 1986, etc. A carboxyl protective group is exemplified by esters (e.g., methyl ester, tert-butyl ester and benzyl ester). Deprotection of this protective group may be carried out by hydrolysis with acid (e.g., hydrochloride and trifluoroacetic acid) or base (e.g., sodium hydroxide) depending on the type of the group, or by catalytic reduction, e.g., under 10% palladium-carbon catalyst condition. To obtain a compound (Ib-1), the esters may directly be converted to hydroxamic acid by the method of process 2. When a compound (XV) is an amino acid wherein R

15

is hydrogen atom, preferable solvents for this sulfonylation are dimethylformamide, tetrahydrofuran, dioxane, dimethylsulfoxide, acetonitrile, water, or mixed solvents thereof. When a compound (XV) is an amino acid wherein R

15

is a protective group such as an ester, a solvent for this sulfonylation is exemplified by the above solvents and mixed solvents of water-insoluble solvents (e.g., benzene and dichloromethane) and the above solvents. A base to be used in this sulfonylation is exemplified by organic bases such as triethylamine, N-methylmorpholine, etc. and inorganic bases such as sodium hydroxide, potassium hydroxide, potassium carbonate, and the like. Usually this reaction can be carried out at ice-cooling to room temperature. When R

of compound (Ia-1) contains a functional group(s) possibly interfering this sulfonylation (e.g., hydroxy, mercapto, amino, and guanidino), it can previously be protected in accordance with a method described in “Protective Groups in Organic Synthesis” (Theodora W. Green (John Wiley & Sons)) and then deprotected at an appropriate process. When R

2

is not hydrogen atom, compound (Ia-1) wherein R

2

is hydrogen atom is further reacted with haloalkyl (e.g., methyl iodide, and ethyl iodide) or haloaralkyl (e.g., benzyl chloride, and benzyl bromide) in dimethylformamide, tetrahydrofuran, dioxane, and the like at a temperature range of ice-cooling to 80° C., preferably ice-cooling to room temperature, for 3-10 hours, preferably 10-20 hours to give the desired N—R

derivative.

(Process 2)

A hydroxylamine is reacted with compound (Ia-1) or its reactive derivatives to give hydroxamic acid derivatives (Ib-1). A hydroxylamine is usually used as its acidic salts (e.g., hydrochloride, and phosphate, sulfate: commercially available) in the presence of a base. A base to be used in this reaction is exemplified by organic bases such as triethylamine, N, N-dimethylaniline, N-methylmorpholine, etc. and inorganic bases such as sodium hydroxide, potassium hydroxide, potassium carbonate, etc. When compound (Ia-1) is used as a starting material of conversion to hydroxamic acid, this reaction is carried out in the presence of a peptide condensing agent (e.g., dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, N,N′-carbonyldiimidazole, or a mixture of one of the above agents with 1-hydroxybenzotriazole, N-hydroxy sucinicimide, etc.). A solvent for this reaction may be dimethylformamide, tetrahydrofuran, dioxane, dimethylsulfoxide, acetonitrile, water, and mixed solvent thereof This reaction is carried out at −20° C. to 40° C., preferably ice-cooling to room temperature, for 1 to 16 hours.

Acid anhydrides (especially, mixed acid anhydrides), acid halides, acid azides, and esters can be utilized in this reaction as a reactive derivative of compound (Ia-1). These reactive derivatives are produced by usual methods. For example, the acid anhydride derivatives can be produced by a reaction of compound (Ia-1) with acid halide derivatives (e.g., ethyl chlorocarbonate) in the presence of a base (e.g., triethylamine), and acid halide derivatives can be produced by a reaction of compound (Ia-1) with a halogenation agent (e.g., oxalylchloride, and thionylchloride). Ester derivatives may be inactive or active. Sulfonyl derivatives converted from a compound (XV) wherein R

15

is a carboxyl protective groups (e.g., methyl, tert-butyl, and benzyl) at process 1 can be used as inactive esters without deprotection. Active esters can be produced by a reaction of compound (Ia-1), carbodiimide reagents (e.g., dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide), and hydroxy derivatives corresponding to the active ester residue such as 1-hydroxybenzotriazole, N-hydroxysuccinimide, or the like. A reaction condition of conversion of the reactive derivatives of compound (Ia-1) to hydroxamic acid may be the same as that of conversion of compound (Ia-1) itself to hydroxamic acid. The reactions of processes 1 and 2 are able to continuously be carried out in one-pot reaction.

(Process 3)

A protected hydroxylamine to be used in this reaction includes O-benzylhydroxylamine, O-(p-methoxybenzyl)hydroxylamine, O-(tert-butyl)hydroxylamine, or the like. This reaction condition may be in the same manner as that of process 2.

(Process 4)

This process for deprotection is carried out by catalytic reduction, treatment with conc. hydrochloric acid, or treatment with trifluoroacetic acid to give the desired compound (Ib-1). The compounds of this invention (Ia-1) and (Ib-1) can be isolated and purified by usual separation methods and purification methods (e.g., chromatography, crystallization, etc.).

EXAMPLE 209

(Method E)

Process 1

To a solution of 20.94 g (99.8 mmol) of D-valine tert-butyl ester hydrochloride (XV-3) in 200 ml of dichloromethane was added 22 ml (2×99.8 mmol) of N-methylmorpholine and 20.27 g (99.8 mmol) of p-styrenesulfonyl chloride under ice-cooling. After being stirred for 15 h at room temperature, the reaction mixture was washed with 2N HCl, 5% NaHCO

Test examples on the compounds of the present invention are described below. The test compounds are the ones described in the Examples and Tables.

Test example

(1) Isolation and purification of MMP-9 (92 kDa, gelatinase B)

Type IV collagenase (MMP-9) was purified according to the methods described in the following literature. Scott M. Wilhelm et al., J. Biol. Chem., 264, 17213-17221, (1989), SV40-transformed Human Lung Fibroblasts Secrete a 92-kDa Type IV Collagenase Which Is Identical to That Secreted by Normal Human Macrophages; Yasunori Okada et al., J. Biol. Chem., 267, 21712-21719, (1992), Matrix Metalloproteinase 9 (92-kDa Gelatinase/Type IV Collagenase) from HT 1080 Human Fibrosarcoma Cells; Robin V. Ward et al., Biochem. J., (1991) 278, 179-187, The purification of tissue inhibitor of metalloproteinase-2 from its 72 kDa progelatinase complex.

MMP-9 is secreted from human fibrosarcoma cell line ATCC HT 1080, into its culture medium when it is stimulated with 12-tetradecanoylphorbol-13-acetate (TPA). The production of MMP-9 in this culture was verified by the gelatin zymography as described in the following literature (Hidekazu Tanaka et al., (1993) Biochem. Biophys. Res. Commun., 190, 732-740, Molecular cloning and manifestation of mouse 105-kDa gelatinase cDNA). The condition medium of the stimulated HT 1080 was concentrated and was purified with gelatin-Sepharose 4B, concanavalin A-sepharose, and Sephacryl S-200. The purified pro-MMP-9 (92 kDa, gelatinase B) thus obtained gave a single positive band in the gelatin zymography. Subsequently, activated MMP-9 was obtained by treating the pro-MMP-9 with trypsin.

(2) Assay methods of type IV collagenase inhibitors

Collagenase assay was performed using the activated MMP-9 described above and the substrate supplied in the type IV collagenase activity kit (YAGAI, inc.), according to the manufacturer's protocol. The following 4 assays are performed per compound (inhibitor).

(A) substrate (type IV collagenase), enzyme (MMP-9), inhibitor

(B) substrate (type IV collagenase), inhibitor

(C) substrate (type IV collagenase), enzyme (MMP-9)

(D) substrate (type IV collagenase)

According to the manufacturer's protocol, fluorescent intensity was measured and percent inhibition was determined by the following equation.

Inhibition

(%)={1−(

A−B

)/(

C−D

))×100

IC

50

is a concentration at which the percent inhibition reaches 50%. The results are shown in Tables 47 to 54.
