Quinoline derivatives and quinazoline derivatives

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to quinoline derivatives and quinazoline derivatives having antitumor activity. More particularly, the present invention relates to quinoline derivatives and quinazoline derivatives that are useful for the treatment of diseases such as tumor, diabetic retinopathy, chronic rheumatism, psoriasis, atherosclerosis, and Kaposi's sarcoma.

2. Background Art

WO 97/17329 describes quinoline derivatives and quinazoline derivatives having antitumor activity. WO 97/17329, however, discloses neither the effects of these quinoline derivatives and quinazoline derivatives on cytomorphosis nor the compounds according to the present invention.

SUMMARY OF THE INVENTION

The present inventors have found that a group of quinoline derivatives and quinazoline derivatives has antitumor activity and, at the same time, has no significant effect on cytomorphosis. The activity of increasing the cell size may be regarded as activity of inducing tissue disorders.

An object of the present invention is to provide compounds which have antitumor activity and, at the same time, have no significant effect on cytomorphosis.

Further, the compounds according to the present invention may form solvates (for example, hydrates).

Production of Compounds

The compounds according to the present invention may be produced, for example, according to scheme 1 and scheme 2.

Starting compounds necessary for the synthesis of the compounds according to the present invention may be commercially available, or alternatively may be produced according to a conventional process. For example, a 4-chloroquinoline derivative may be synthesized by a conventional process as described in Org. Synth. Col. Vol. 3, 272 (1955), Acta Chim. Hung., 112, 241 (1983) or WO 98/47873. A 4-chloroquinazoline derivative may be synthesized by a conventional process as described in J. Am. Chem. Soc., 68, 1299 (1946) or J. Am. Chem. Soc., 68, 1305 (1946).

Alternatively, the 4-chloroquinazoline derivative may be produced by a process which comprises the steps of: (1) first reacting a benzoic ester with formamide to prepare a quinazolone derivative (see Production Example 34) and (2) then heating the 4-quinazolone derivative using toluene or sulfolane as a solvent in the presence of phosphorus oxychloride (see Production Examples 35 and 36). The quinazolone derivative is generally synthesized in the presence of a benzoic ester, sodium methoxide, formamide, and a solvent such as DMF or methanol. In the step (1), the reaction proceeds in a system where only the benzoic ester and formaldehyde are present. This is advantageous in that the synthesis can be carried out using a small number of starting compounds. The 4-quinazolone derivative is generally halogenated by heating the quinazolone derivative and phosphorus oxychloride. In this case, in many cases, due to high reactivity of the quinazoline derivative, the influence of the solvent has caused the quinazoline derivative to be returned to the starting compound and consequently made it impossible to complete the reaction. In the step (2), the reaction is completed in the presence of toluene or sulfolane, and, thus, this is advantageous from the viewpoint of an increase in yield.

Next, 4-chloroquinoline derivative or a corresponding quinazoline derivative is allowed to act on nitrophenol in the presence of a suitable solvent or in the absence of a solvent to synthesize a 4-(nitrophenoxy)quinoline derivative or a corresponding quinazoline derivative which is then stirred in a suitable solvent, for example, N,N-dimethylformamide, in the presence of a catalyst, for example, palladium hydroxide-carbon or palladium-carbon, in a hydrogen atmosphere to give a 4-(aminophenoxy)quinoline derivative or a corresponding quinazoline derivative. Alternatively, a 4-chloroquinoline derivative or a corresponding quinazoline derivative may be allowed to act on aminophenol in the presence of a base, for example, sodium hydride, to give a 4-(aminophenoxy)quinoline derivative or a corresponding quinazoline derivative.

Alternatively, the 4-(aminophenoxy)quinoline derivative or the corresponding quinazoline derivative may also be produced by dissolving aminophenol in an aqueous sodium hydroxide solution and then subjecting the solution to a two-phase reaction with a solution of a 4-chloroquinazoline derivative or a corresponding quinazoline derivative in an organic solvent in the presence of a phase transfer catalyst or in the absence of a catalyst (see Production Examples 37 and 38). In this reaction, for example, phenol remaining unreacted and a decomposition product of 4-chloroquinazoline are left in the aqueous layer, while the target product is present in the organic layer. That is, the organic layer contains only the target product. Therefore, the post-treatment is advantageously simple. Further, the production of N-alkylaminophenoxy-quinazoline as a by-product can be advantageously suppressed.

The 4-(aminophenoxy)quinoline derivative or the corresponding quinazoline derivative thus obtained may be reacted with an acid chloride or an acid anhydride in the presence of a base, followed by reduction, for example, with lithium aluminum hydride to introduce a substituent into R

9

(step 1A).

Alternatively, the 4-(aminophenoxy)quinoline derivative or the corresponding quinazoline derivative may be reacted with an aldehyde or a ketone to produce an imine, followed by reduction, for example, with sodiumboroncyanohydride to introduce a substituent into R

9

(step 1B).

The derivative with a substituent introduced into R

9

is allowed to act on an isocyanate derivative (O═C═N—R

11

) by a conventional method (step 2), and a suitable alkylating agent (R

10

Hal) is allowed to act in the presence of a base, for example, sodium hydride (step 3) to produce the compound of formula (I).

Alternatively, R

9

and R

10

may also be introduced by allowing a suitable alkylating agent (R

9

Hal, R

10

Hal) to act on a urea derivative, wherein R

9

and/or R

10

represent a hydrogen atom, in the presence of a base, for example, sodium hydride (steps 5 and 7).

The urea derivative, wherein R

9

and/or R

10

represent a hydrogen atom, may be produced by allowing an isocyanate derivative to act on the 4-(aminophenoxy)quinoline derivative or the corresponding quinazoline derivative, produced in scheme 1, according to a conventional method, or by adding a triphosgene to the 4-(aminophenoxy)quinoline derivative or the corresponding quinazoline derivative in the presence of a base, for example, triethylamine, and then reacting the mixture with a suitable alkylamine (R

11

NH

, R

R

11

NH) (steps 4 and 6).

The derivative having a specific substituent at the 7-position of the quinoline ring may be produced, for example, according to scheme 3.

A suitable substituent (for example, benzyl) may be allowed to act on a commercially available 4′-hydroxyacetophenone derivative to protect the hydroxyl group, followed by action of a nitrating agent (for example, nitric acid-acetic acid) to introduce a nitro group.

The nitro group may be then reduced to an amino group which is then reacted with a formic ester in the presence of a base to form a quinolone ring, followed by action of a chlorinating agent, for example, phosphorus oxychloride, to produce a 4-chloroquinoline derivative.

The 4-chloroquinoline derivative thus obtained may be allowed to act on aminophenol in the presence of a base, for example, sodium hydride, to produce a 4-(aminophenoxy)quinoline derivative.

The urea portion may be synthesized by allowing an isocyanate derivative (O═C═N—R

29

) to act on the derivative thus obtained according to a conventional method, or by treating the derivative with triphosgene and then allowing an aromatic amine or alkylamine (R

29

NH

2

) to act on the treated derivative.

Next, the protective group (PG) for the hydroxyl group at the 7-position of the quinoline ring may be removed, followed by action of an alkyl halide (R

22′

Hal wherein R

22′

represents an alkyl portion when R

22

represents alkoxy) in the presence of a base, or by action of an alcohol derivative (R

22′

OH) according to a conventional method, for example, Mitsunobu reaction, to produce a compound, according to the present invention, having an alkoxy group at the 7-position of the quinoline ring.

The alkyl halide used in the substitution reaction may be commercially available or produced according to a process described, for example, in J. Am. Chem. Soc., 1945, 67, 736.

The alcohol derivative used in the substitution reaction may be commercially available or produced according to a process described, for example, in J. Antibiot. (1993), 46(1), 177 and Ann. Pharm. Fr. 1977, 35, 503.

The derivative having a specific substituent at the 6-position of the quinoline ring may be produced using 3′-hydroxyacetophenone derivative as the starting compound according to scheme 3.

The derivative having a specific substituent at the 7-position of the quinazoline ring may be produced according to scheme 4.

The 2-amino-benzoic ester derivative may be produced by esterifying a 2-nitro-benzoic acid derivative synthesized according to a method described, for example, in J. Med. Chem. 1977, 20, 146, for example, with dimethylsulfuric acid in the presence of a base, for example, potassium carbonate and then reducing the nitro group, for example, with iron/acetic acid.

Next, the compound thus obtained may be allowed to act on formamide in the presence of a base to form a 4-quinazolone ring, followed by action of a chlorinating agent, for example, phosphorus oxychloride, to produce a 4-chloroquinazoline derivative.

The 4-chloroquinazoline derivative thus obtained may be allowed to act on an aminophenol derivative in the presence of a base, for example, sodium hydride, to produce a 4-(aminophenoxy)quinazoline derivative.

The urea portion may be synthesized by allowing an isocyanate derivative (O=C=N—R

29

) to act on the derivative thus obtained according to a conventional method, or by treating the derivative with triphosgene and then allowing an aromatic amine or alkylamine (R

29

NH

2

) to act on the treated derivative.

Next, the protective group (PG) for the hydroxyl group at the 7-position of the quinazoline ring may be removed, followed by action of an alkyl halide (R

22′

Hal wherein R

22′

represents an alkyl portion when R

22

represents alkoxy) in the presence of a base, or by action of an alcohol derivative (R

22′

OH) according to a conventional method, for example, Mitsunobu reaction, to produce a compound, according to the present invention, having an alkoxy group at the 7-position of the quinazoline ring.

The alkyl halide and the alcohol derivative used in the substitution reaction may be commercially available or produced according to a process described in the literature referred to in the description of scheme 3.

The derivative having a specific substituent at the 6-position of the quinazoline ring may be produced using 3-hydroxybenzaldehyde derivative as the starting compound according to scheme 4.

Use of Compounds/pharmaceutical Composition

Further, the compounds according to the present invention inhibit in vitro the activation of MAPK (mitogen-activated protein kinase) caused by stimulation of vascular endothelial cells with VEGF (vascular endothelial growth factor) (see Pharmacological Test Examples 1 and 2). Upon the stimulation of vascular endothelial cells with VEGF, MAPK is activated by a signal transmission system downstream of the receptor, and, consequently, an increase in phosphorylated MAPK is lo recognized (Abedi, H. and Zachary, I., J. Biol. Chem., 272, 15442-15451 (1997)). The activation of MAPK is known to play an important role in the growth of vascular endothelial cells in angiogenesis (Merenmies, J. et al., Cell Growth & Differ., 83-10 (1997); and Ferrara, N. and Davis-Smyth, T., Endocr. Rev., 18, 4-25 (1997)). Therefore, the compounds according to the present invention have angiogenesis inhibitory activity.

Angiogenesis at pathologic sites is deeply involved mainly in diseases, such as tumor, diabetic retinopathy, chronic rheumatism, psoriasis, atherosclerosis, and Kaposi's sarcoma, and metastasis of solid tumors (Forkman, J. Nature Med. 1: 27-31 (1995); Bicknell, R., Harris, A. L. Curr. Opin. Oncol. 8: 60-65 (1996)).

Binders include, for example, dimethylcellulose, polyvinyl alcohol, polyvinyl ether, methylcellulose, ethylcellulose, gum arabic, gelatin, hydroxypropylcellulose, and polyvinyl pyrrolidone. Lubricants include, for example, talc, magnesium stearate, polyethylene glycol, and hydrogenated vegetable oils.

In preparing injections, if necessary, for example, buffers, pH adjustors, stabilizers, tonicity agents, and preservatives may be added.

The content of the compound according to the present invention in the pharmaceutical composition according to the present invention may vary according to the dosage form. In general, however, the content is 0.5 to 50% by weight, preferably 1 to 20% by weight, based on the whole composition.

The dose may be appropriately determined in consideration of, for example, the age, weight, sex, difference in diseases, and severity of condition of patients, and the preparation may be administered, for example, in an amount of 0.1 to 100 mg/kg, preferably 1 to 50 mg/kg. This dose is administered at a time daily or divided doses of several times daily.

The compound according to the present invention may be administered in combination with other medicament(s). In this case, the compound according to the present invention may be administered simultaneously with or after or before the administration of other medicament(s). For example, when the object disease is malignant tumor, the compound according to the present invention can be allowed to act on target vascular endothelial cells to allow the tumor to regress, followed by the administration of a carcinostatic agent to effectively eliminate the tumor.
