Description

Field of the Invention



[0001] The present invention relates to a novel substituted bicyclic derivative. More specifically, the present invention relates to a substituted bicyclic derivative useful as an active ingredient of medicaments.

Background Art



[0002] Various kinds of prostaglandins and various kinds of leukotrienes are produced in the bodies of mammals in response to variety of stimuli such as inflammatory stimuli and physical stimuli.
Both of prostaglandins and leukotrienes are metabolites of arachidonic acid, and they are physiologically active substances referred to as lipid mediators, and they cause various physiological responses of mammals by binding to receptors expressed on surfaces of various cells or in the cells.
Arachidonic acid is produced from a phospholipid as a substrate, such as phosphatidylcholine which is a cell membrane component, with the aid of an enzymatic activity of phospholipase A2 (PLA2).

[0003] Arachidonic acid produced by the action of PLA2 is converted into prostaglandin (PG) H2 with the aid of an enzymatic activity of constitutive type cyclooxygenase (COX) 1 or inducible type COX-2, and further converted into PGE2, PGD2, PGF2α, PGI2, thromboxane (TX) A2 and the like with the aid of each synthetic enzyme. Further, arachidonic acid is also metabolized by the action of 5-lipoxygenase (5-LO) and thereby converted to leukotriene (LT) A4, and further converted to LTB4, LTC4, LTD4, LTE4 and the like by the enzymatic activities of LTA4 hydrolase, LTC4 synthase, glutathione S-transferase and the like [Goodman & Gilman, Pharmacological Basis of Therapeutics, 9th edition, p.801, 1999 (Hirokawa Shoten); Funk, C.D., SCIENCE, vol. 294, p.1871, 2001].

[0004] Prostaglandins bind to each specific receptor to cause inflammatory reactions such as fervescence, enhancement of vascular permeability, vasodilation, swelling and pain, bronchial smooth muscle contraction, platelet aggregation, tumor cell proliferation, enhancement of bone resorption, nerve cell degeneration and the like, and thus play important roles in expression of symptoms or pathological formation for various diseases.
Leukotrienes are physiologically active substances which bind to each specific receptor to cause inflammatory reactions such as excessive accumulation of leucocytes and enhancement of vascular permeability, smooth muscle contraction, mucus secretion, proliferation of tumor cells and the like, and thus play important roles in expression of symptoms or pathological formation for various diseases.

[0005] Although inflammatory reactions themselves are essential reactions for living bodies to survive when they face pathogenic substances and affections, they are sometimes excessively caused or continue without any reason for providing evident benefit under certain situations or in certain diseases [Goodman & Gilman, Pharmacological Basis of Therapeutics, 9th edition, p.827, 1999 (Hirokawa Shoten)]. The condition of living body referred to in this specification wherein an acute or chronic inflammatory reaction is observed means a condition that an excessive or unbeneficial acute or temporary inflammatory reaction or chronic and persistent inflammatory reaction is caused. Further, an inflammatory reaction refers to a series of events caused by stimuli, for example, physical hazards such as heat, infective substances, ischemia, antigen/antibody reaction and the like, and it is accompanied by flare, swelling, hyperalgesia, algesic onset and the like as well-known macroscopic clinical symptoms. It is known that, as histological mechanisms for these reactions, vasodilation, enhancement of vascular permeability, infiltration of leucocytes and phagocytes, histological decomposition and fibrosing and the like are caused [Goodman & Gilman, Pharmacological Basis of Therapeutics, 9th edition, p.827, 1999 (Hirokawa Shoten)]. It is known that many of these histological reactions are caused by prostaglandins and/or leukotrienes, and prostaglandins and/or leukotrienes plays important roles in inflammatory reactions.

[0006] For example, it was reported that, in a pathological tissue of rheumatoid arthritis, which is an autoimmune and chronic inflammatory disease, expression of COX-2 and production of PGE2 and TXA2 as well as expression of 5-LO and production of LTB4 were observed (Bonnet et al., Prostaglandins, 1995, vol. 50, p.127), and in a mouse deficient in FLAP, which is a protein required for activation of 5-LO, symptom of collagen-induced arthritis, which is a pathological model of chronic rheumatoid arthritis, was milder compared with that in a wild-type mouse (Griffiths et al., J. Exp. Med., 1997, vol. 185, p.1123), and thus it has been suggested that prostaglandins and leukotrienes play important roles in the pathological formation of chronic rheumatoid arthritis.

[0007] It was reported that, in a pathological tissue of bronchial asthma, one of chronic allergic diseases, excessive production of PGD2 and TXA2 as well as excessive production of LTC4 and LTD4 were observed (Wenzel et al., Am Rev. Respir. Dis., 1990, vol. 142, p.112), and an airway hypersensitive reaction, which is a pathological model of bronchial asthma, was unlikely to occur in a PGD2 receptor-deficient mouse (Matsuoka et al., SCIENCE, vol. 287, p.2013, 2000). Thus, it has been demonstrated that roles of prostaglandins and leukotrienes are important in bronchial asthma.

[0008] In a cerebral tissue after ischemic reperfusion, expression of COX-2 increased, and concentrations of PGE2 and TXA2 increased, whereas activity of 5-LO increased, and production amount of LTC4 increased (Ohtsuki et al., Am. J. Physiol., 1995, vol. 268, p.1249). Thus, it is known that prostaglandins and leukotrienes play important roles in formation of infarct that is accepted as an ischemic reperfusion injury.
It has been revealed that, in a pathological tissue of Alzheimer's disease, one of the diseases with neurodegeneration, the COX activity and 5-LO activity increased, prostaglandins and leukotrienes cause formation of the β-amyloid protein, one of the pathogenic substances of Alzheimer's disease, and further cause degeneration of nerve cells (Sugaya et al., Jpn. J. Pharmacol., 2000, vol. 82, p.85), and thus it is believed that prostaglandins and leukotrienes play important roles in the formation of neurodegenerative diseases such as Alzheimer's disease.

[0009] Furthermore, for example, it was reported that, in a pathological tissue of colon cancer, COX and 5-LO were expressed, and amounts of production of prostaglandins and leukotrienes were increased (Dreyling et al., Biochim. Biophys. Acta., 1986, vol. 878, p. 184), and leukotriene caused increase in colon cancer cells (Qiao et al., Biochim. Biophys. Acta, 1995, vol. 1258, p.215; Hong et al., Cancer Res., 1999, vol. 59, p.2223). Thus, it is believed that prostaglandins and leukotrienes play important roles also in tissues of large bowel cancer.
Involvement of prostaglandins and/or leukotrienes in diseases and pathological conditions is not limited to those diseases exemplified above, and it has been demonstrated that prostaglandins and/or leukotrienes are involved in variety of conditions, various diseases, or various pathological conditions where acute or chronic inflammatory reactions are observed and their roles are important.

[0010] For the above reason, various prostaglandin production suppressors or leukotriene production suppressors are used as agents for prophylactic or therapeutic treatment of conditions, various diseases or pathological conditions where an acute or chronic inflammatory reaction is recognized. Various non-steroidal antiinflammatory drugs (NSAIDS) as medicaments having a prostaglandin production-suppressing action are available and used as therapeutic agents for chronic rheumatoid arthritis and osteoarthritis, antiphlogistic- analgesic agents for injury and the like, prophylactic agents for cerebral infarction or myocardial infarction, prophylactic agents for colon polyposis and the like. However, the class of NSAIDS suppress only production of prostaglandins, and as a result, they increase amounts of production of leukotrienes, and exhibit side effects such as asthmatic attack and gastrointestinal injury as well as side effects such as renal disturbance.
Furthermore, a difference between an effective dose and a dose inducing the side effects is small in these NSAIDS, and no satisfactory agent is available from a viewpoint of therapeutic effect. A 5-LO inhibitor is available which is described in European Patent No. 279263 as a medicament having a leukotriene production-suppressing action, and the inhibitor is known as a prophylactic agent for asthma. However, since the agent causes side effects such as hepatic disorder, its dosage is limited, and the agent is not satisfactory also from a viewpoint of therapeutic effect. Since steroid agents suppress production of both of prostaglandins and leukotrienes, they are used as prophylactic agents or therapeutic agents for conditions of living bodies, various diseases and pathological conditions where various acute or chronic inflammatory reactions are observed. However, their actions are not limited to the lipid mediator production-suppressing action, and they exhibit severe side effects such as induction and exacerbation of infectious diseases due to the immunosuppression action, growth retardation due to normal cell antiproliferative activity, anetoderma and peptic ulcer. Therefore, their uses are limited.

[0011] Furthermore, for the above reasons, it is considered that compounds, that suppress the production of both of prostaglandins and leukotrienes and have reduced side effect, are effective as therapeutic agents or prophylactic agents for such conditions of living bodies, diseases or pathological conditions in mammals as described above, and methods of using such compounds together with medicaments available at present are more effective therapeutic or prophylactic methods. Therefore, development of compounds suppressing the production of both of prostaglandins and leukotrienes, and manufacture of pharmaceutical preparations thereof are strongly desired.

[0012] As compounds structurally similar to the compounds of the present invention, for example, biphenyl-5-alkanoic acid derivatives and use thereof are reported in WO99/19291. However, the moieties of these compounds that correspond to the ring (E) and "AR" included in the formula (I) of the compounds of the present invention are phenyl groups, and thus structural features of the above compounds are different. Further, biaryl phospholipase A2 inhibitors are described in U.S. Patent No. 5,391,817 [Japanese Patent Unexamined Publication (Kokai) No. 7-22399]. However, the moieties of these compounds that correspond to the ring (E) and "AR" included in the formula (I) of the compounds of the present invention are defined only to be phenyl group, and thus the structural features of the above compounds are different.
Bicyclic heterocyclic compounds are reported in WO00/35886 as protease inhibitors. However, the moieties of these compounds that correspond to the ring (E) and the substituents on "AR" included in the formula (I) of the compounds of the present invention are different, and further, the publication is completely silent about whether or not the compounds disclosed in the above patent document have any prostaglandin production-suppressing action or leukotriene production-suppressing action. Indanacetic acid derivatives are reported in WO03/011842, and indane-, dihydrobenzofuran-, and tetrahydronaphthalene-carboxylic acid derivatives are reported in WO04/011446. However, the moieties of these compounds that correspond to "AR" included in the formula (I) of the compounds of the present invention are different, and further, the publication is completely silent about whether or not the compounds disclosed in the above patent specifications have any prostaglandin production-suppressing action or leukotriene production-suppressing action. Moreover, substituted phenylalkanoic acid derivatives and uses thereof are reported in WO03/07686. However, the moieties of these compounds that correspond to the ring (E) included in the formula (I) of the compounds of the present invention are limited to benzene ring, and thus structural features thereof are different. Substituted arylalkanoic acid derivatives and uses thereof are reported in WO05/016862. However, the moieties of these compounds that correspond to the ring (E) included in the formula (I) of the compounds of the present invention are limited to benzene ring and pyridine ring, and thus structural features thereof are different.

Best Mode for Carrying out the Invention



[0020] This application is a patent application filed with claiming a conventional priority based on Japanese Patent Application No. 2006-095008 filed in Japan on March 30, 2006. The entire disclosures of Japanese Patent Application No. 2006-095008 including those of the specification and the claims are incorporated herein by reference.
In the present specification, carbon atom may sometimes be represented simply by "C", hydrogen atom by "H", oxygen atom by "O", sulfur atom by "S", and nitrogen atom by "N".
- - - - in the aforementioned formula (I) represents a single bond, or a double bond. However, both the bond between the ring-constituting carbon atom at the 1-position of the ring (E) and the ring-constituting carbon atom at the 2-position of the ring (E), and the bond between the ring-constituting carbon atom at the 1-position of the ring (E) and the Link moiety do not simultaneously represent a double bond, and when Link represents a single bond, the bond between the ring-constituting carbon atom at the 1-position of the ring (E) and the Link moiety represents a single bond.
When the bond between the ring-constituting carbon atom at the 1-positi on of the ring (E) and the ring-constituting carbon atom at the 2-position of the ring (E), and the bond between the ring-constituting carbon atom at the 1-posit ion of the ring (E) and the Link moiety in the formula (I) both represent a sing le bond, the ring-constituting carbon atom at the 1-position of the ring (E) is an asymmetric carbon atom, and at least two kinds of optical isomers exist. Stere oisomers such as the aforementioned optical isomers and diastereomers occurring due to an asymmetric carbon existing in a substituent other than the aforemen tioned asymmetric carbon in pure forms, arbitrary mixtures of such stereoisomer s, racemates and the like all fall within the scope of the present invention.

[0021] Examples of Link in the aforementioned formula (I) include a single bond, and a saturated or unsaturated straight hydrocarbon chain having 1 or 2 carbon atoms.
When Link represents a single bond, it is meant that the ring-constituting carbon atom at the 1-position of the ring (E) and COOY in the formula (I) are directly bound, and in such case, the ring-constituting carbon atom at the 1-position of the ring (E) and COOY are bound with a single bond.
As the saturated straight hydrocarbon chain having 1 or 2 carbon atoms, CH2 or CH2CH2 is preferred, CH2 is particularly preferred. When Link represents any one of these saturated hydrocarbon chains, the bond between the ring-constituting carbon atom at the 1-position of the ring (E) and the Link moiety are bound with a single bond.
The unsaturated hydrocarbon chain having 1 or 2 carbon atoms means a hydrocarbon chain in which the carbon-carbon bonds including the bond with the ring-constituting carbon atom at the 1-position of the ring (E) include an unsaturated bond which is a double bond or a triple bond. Specific examples of the unsaturated hydrocarbon chain including bond between the ring-constituting carbon atom at the 1-position of the ring (E) and COOY include:

the ring-constituting carbon atom at the 1-position of the ring (E)(double bond)CH-COOY;

the ring-constituting carbon atom at the 1-position of the ring (E)(double bond)CHCH2-COOY;

the ring-constituting carbon atom at the 1-position of the ring (E)-CH(double bond)CH-COOY;

the ring-constituting carbon atom at the 1-position of the ring (E)(double bond)C-(double bond)CH-COOY;

the ring-constituting carbon atom at the 1-position of the ring (E)-C(triple bond)C-COOY;

and the like. Among them,

the ring-constituting carbon atom at the 1-position of the ring (E)(double bond)CH-COOY;

is a particularly preferred example.

As Link, CH, CH2, and CH2CH2 are preferred examples, CH, and CH2 are particularly preferred examples, and CH2 is an extremely preferred example.

[0022] W in the aforementioned formula (I) represents a single bond, methylene group, oxygen atom, sulfur atom, or N(Rw). Specifically, when W represents a single bond, the ring (E) represents benzocyclobutane ring or benzocyclobutene ring, when W represents methylene group, the ring (E) represents indan ring or indene ring, when W represents oxygen atom, the ring (E) represents dihydrobenzofuran ring or benzofuran ring, when W represents sulfur atom, the ring (E) represents dihydrobenzothiophene ring or benzothiophenering, and when W represents N(Rw), the ring (E) represents indoline ring or indole ring. Preferred examples of W include methylene group, oxygen atom, N(Rw) and the like, and methylene group is a particularly preferred example.
Rw in N(Rw) as W represents hydrogen atom, an alkyl group having 1 to 8 carbon atoms or -A6-Qp. The alkyl group having 1 to 8 carbon atoms represents such a linear or branched saturated alkyl group, linear or branched alkyl group partially containing unsaturated bond, or alkyl group which may contain a cycloalkyl group having 3 to 7 carbon atoms, and examples include, for example, methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, t-butyl group, pentyl group, isopentyl group, 2-methylbutyl group, 2,2-dimethylpropyl group, hexyl group, 4-methylpentyl group, 2,3-dimethylbutyl group, 2-ethylbutyl group, heptyl group, octyl group, cyclopropyl group, cyclobutyl group, cyclopentyl group, cyclohexyl group, cycloheptyl group, cyclopropylmethyl group, cyclobutylmethyl group, cyclopentylmethyl group, cyclohexylmethyl group, cycloheptylmethyl group, 2-cyclopentylethyl group, 2-cyclohexylethyl group, 2-methylcyclopentyl group, 3-methylcyclopentyl group, 3,4-dimethylcyclopentyl group, 4-methylcyclohexyl group, 4,4-dimethylcyclohexyl group, 4-ethylcyclohexyl group, 4-methylcyclohexylmethyl group, and the like. As Rw, hydrogen atom, methyl group and the like are preferred examples.

[0023] A6 in the substituent -A6-Qp represents a single bond or methylene group, and Qp represents a phenyl group which may be substituted with one of T1 or two or more of the same or different T1. The substituent T1 is a linear or branched saturated alkyl group having 1 to 4 carbon atoms, hydroxyl group, fluorine atom, chlorine atom, bromine atom, trifluoromethyl group, nitro group, an alkoxy group having 1 to 4 carbon atoms, or a mono- or dialkylamino group having 1 to 4 carbon atoms. Specific examples of -A6-Qp include phenyl group, methylphenyl group, chlorophenyl group, benzyl group, methylbenzyl group, chlorobenzyl group, dichlorobenzyl group, fluorobenzyl group, trifluoromethylbenzyl group, nitrobenzyl group, methoxyphenyl group, N-methylaminobenzyl group, N,N-dimethylaminobenzyl group, and the like.
In this specification, as represented by A6, Qp and T1, for example, the same symbols may sometimes be used simultaneously at different positions. These symbols are used to mean the same class of groups of substituents. However, because each substituent is independently chosen from each other, the same symbols do not mean that an identical substituent should be necessarily chosen, and as a result, selection of the same or different kind of substituent is not prohibited.

[0094] By removing these protective groups simultaneously with the preparation or stepwise during the preparation process or at the final step, protected compounds can be converted into objective compounds.

These methods are specifically performed as follows.
  1. (1) The deprotection reaction by alkali hydrolysis is performed by, for example, reacting a protected compound with a base in a polar solvent. Examples of the base used in this reaction include, for example, alkali metal bases such as sodium hydroxide, potassium hydroxide, lithium hydroxide, barium hydroxide, calcium hydroxide, sodium carbonate, potassium carbonate, sodium methoxide, and potassium t-butoxide, and organic bases such as triethylamine. They are usually used in an amount of 1 to 20 moles, preferably 1 to 10 moles, based on the reactant, when an alkali metal base is used, or 1 fold mole to a large excess amount, when an organic base is used. As for the reaction solvent, it is usually preferred that the reaction is performed in an inactive medium that does not inhibit the reaction, preferably a polar solvent. Examples of the polar solvent include water, methanol, ethanol, tetrahydrofuran, dioxane, and the like, and these can be used as a mixture as required. As the reaction temperature, a suitable temperature, for example, from - 10°C to the reflux temperature of the solvent, is chosen. The reaction time is, for example, usually 0.5 to 72 hours, preferably 1 to 48 hours, when an alkali metal base is used, or 5 hours to 14 days, when an organic base is used. However, since the progress of the reaction can be monitored by thin layer chromatography (TLC), high performance liquid chromatography (HPLC), or the like, it is usually preferred that the reaction is terminated when the maximum yield of the objective compound is obtained.

(2) The deprotection reaction under an acidic condition is performed, for example, in an organic solvent (dichloromethane, chloroform, dioxane, ethyl acetate, anisole and the like) in the presence of an organic acid (acetic acid, trifluoroacetic acid, methanesulfonic acid, p-toluenesulfonic acid and the like), a Lewis acid (boron tribromide, boron trifluoride, aluminum bromide, aluminum chloride and the like), or an inorganic acid (hydrochloric acid, sulfuric acid and the like), or a mixture thereof (hydrogen bromide/acetic acid and the like) at a temperature of -10 to 100°C. There is also a method of adding ethanethiol, 1,2-ethanedithiol, or the like as an additive.

(4) The deprotection reaction of silyl group is performed, for example, by using tetra-n-butylammonium fluoride or the like in a water-miscible organic solvent (tetrahydrofuran, acetonitrile and the like) at a temperature of -10 to 60°C.

(5) The deprotection reaction using a metal is performed, for example, in an acidic solvent (acetic acid, buffer of pH 4.2 to 7.2, a mixture of such a solution and an organic solvent such as tetrahydrofuran) in the presence of zinc powder with or without ultrasonication at a temperature of -10 to 60°C.

(6) The deprotection reaction using a metal complex is performed, for example, in an organic solvent (dichloromethane, dimethylformamide, tetrahydrofuran, ethyl acetate, acetonitrile, dioxane, ethanol and the like), water, or a mixture thereof in the presence of a trap reagent (tributyltin hydride, triethylsilane, dimedone, morpholine, diethylamine, pyrrolidine and the like), an organic acid (acetic acid, formic acid, 2-ethylhexanoic acid and the like) and/or an organic acid salt (sodium 2-ethylhexanoate, potassium 2-ethylhexanoate and the like) in the presence or absence of a phosphine type regent (triphenylphosphine and the like) by using a metal complex [tetrakistriphenylphosphine palladium(0), bis(triphenylphosphine) palladium(II) dichloride, palladium(II) acetate, tris(triphenylphosphine) rhodium(I) chloride and the like] at a temperature of -10 to 60°C.

Further, besides the aforementioned methods, the deprotection reaction can be performed by referring to and examining ordinary chemical literatures, for example, Protective Groups In Organic Synthesis, mentioned above, references cited in the literatures, and the like.
As readily understood by those skilled in the art, protected compounds can be easily derived into the desired compounds of the present invention or synthetic intermediates thereof by using a combination of these protection/deprotection reactions, or appropriately choosing and using the reactions.

In the tables mentioned below, data indicated by "LCMS" mean data of liquid chromatography-mass spectrometry spectra. In the columns of "Mass", data of mass spectrometry were shown (the indication "N.D" means that no molecular ion peak was detected). In the columns of "method", elution conditions of the liquid chromatography are described. In the columns of "RTime", retention times in the liquid chromatography are shown. For the indication of retention time in the liquid chromatography, the indication "A" for elution condition means that measurement was performed by elution with a linear gradient of 5 to 100% (v/v) Solution B from 0 minute to 5 minutes and then with 98% Solution B until 9 minutes. Similarly, the indication "B" for elution condition means that measurement was performed by elution with a linear gradient of 5 to 98% (v/v) Solution B from 0 minute to 4 minutes, and then with 98% Solution B until 6 minutes. For the compounds with the indication C in the columns of elution conditions, data of mass spectrometry measured by fast atomic bombardment mass spectrometry (FAB-MS) using JEOL-JMS-SX102 (produced by JEOL Co., Ltd.) were mentioned in the columns of "Mass". Further, for the compounds with the indication D in the elution conditions, an apparatus manufactured by Waters Ltd. was used as a liquid chromatography apparatus. As a column for separation, Develosil C30-UG-5 (50 x 4.6 mm, Nomura Kagaku Co., Ltd.) was used. Measurement was performed under elution condition with a linear gradient of 5 to 98% (v/v) Solution B from 0 minute to 4 minutes and then with 98% Solution B until 6 minutes.

Synthesis of ethyl 2-[4-chloro-5-hydroxy-6-(naphthalen-2-yl)-2,3-dihydro-1H-inden-1-yl]acetate (Intermediate A-30) (Preparation Method 4, Step h-1)



[0194] A solution of Intermediate A-22 (117.7 mg) in chloroform (3 ml) was added with sulfuryl chloride (41 µl, Ald) under ice cooling, and then the mixture was stirred for 10 minutes and stirred at room temperature for 17 hours. The mixture was concentrated under reduced pressure, and then added with water (10 ml) and chloroform (20 ml) for extraction, and then the organic layer was successively washed with saturated aqueous ammonium chloride, saturated aqueous sodium hydrogencarbonate and saturated brine. The organic layer was dried, and then the solvent was evaporated under reduced pressure to obtain the title compound (Intermediate A-30, 119.2 mg). Mass (LCMS): 381 (M++1), Retention time: N.D (Elution condition: C).

Reference Example 5


Synthesis of ethyl 2-[4-bromo-5-hydroxy-6-(naphthalen-2-yl)-2,3-dihydro-1H-inden-1-yl]acetate (Intermediate A-34) (Preparation Method 4, Step h-2)



[0195] A solution of Intermediate A-22 (702.3 mg) in acetonitrile (10 ml) was added with NBS (370.6 mg) under ice cooling, and then the mixture was stirred for 10 minutes and stirred at room temperature 17 hours. The mixture was concentrated under reduced pressure, and then added with water (30 ml) and ethyl acetate (50 ml) for extraction, and then the organic layer was successively washed with saturated aqueous ammonium chloride, 5% aqueous sodium sulfite, saturated aqueous sodium hydrogencarbonate and saturated brine. The organic layer was dried, and then the solvent was evaporated under reduced pressure. The residue was purified by column chromatography (Quad, hexane:ethyl acetate = 8:1) to obtain the title compound (Intermediate A-34, 813.3 mg). Mass (LCMS): 425 (M+), Retention time: N.D (Elution condition: C).
