States of rosuvastatin calcium tablets in 5 mg, 10 mg, 20 mg, and 40 mg dosage strengths, which are generic versions of Plaintiffs' Crestor® Tablets in 5 mg, 10 mg, 20 mg, and 40 mg dosage strengths, respectively. 12. By letter dated October 31, 2007, Aurobindo Pharma notified Plaintiffs that it had

filed an ANDA seeking FDA approval to market rosuvastatin calcium tablets in 5 mg, 10 mg, 20 mg, and 40 mg dosage strengths (hereinafter referred to as "the Aurobindo Rosuvastatin Calcium Tablets"), and that it was providing information to Plaintiffs pursuant to 21 U.S.C. § 355(j)(2)(B)(ii) and 21 C.F.R. § 314.95. 13. On information and belief, Aurobindo Pharma is in the business of developing

and manufacturing generic pharmaceutical products. On information and belief, Aurobindo Pharma sells and delivers its pharmaceutical products to Aurobindo USA in New Jersey. On information and belief Aurobindo USA is the agent, affiliate, representative, and/or alter ego of, and/or acts in concert with, Aurobindo Pharma for the purposes of marketing, distributing, and selling generic pharmaceutical products within the United States, including the State of New Jersey. 14. On information and belief, Aurobindo USA, as the authorized agent of Aurobindo

States. On information and belief, that infrastructure includes Aurobindo USA. On information and belief, Aurobindo Pharma develops and manufactures generic drugs and, directly or indirectly through Aurobindo USA, markets, distributes, and sells its generic drugs throughout the United States, including the State of New Jersey. 17. Personal jurisdiction over Aurobindo Pharma is proper because it purposefully

avails itself of the privilege of selling its generic products in the state of New Jersey and can therefore reasonably expect to be subject to jurisdiction in Courts in New Jersey. Among other things, upon information and belief, Aurobindo Pharma, directly or through its subsidiary Aurobindo USA, places goods into the stream of commerce for distribution throughout the United States, including the State of New Jersey. In addition, Aurobindo Pharma maintains continuous and systematic contacts with its wholly owned subsidiary, Aurobindo USA, in the State of New Jersey. 18. Personal jurisdiction over Aurobindo USA is proper because Aurobindo USA's

principal place of business is in this judicial district and, thus, Aurobindo USA has purposely availed itself of the privilege of doing business in the State of New Jersey. Further, Aurobindo USA maintains continuous and systematic contacts with the State of New Jersey so as to reasonably allow jurisdiction to be exercised over it. 19. Venue is proper in this judicial district under 28 U.S.C. §§ 1391(c) and 1400(b). Count I Infringement of United States Patent No. RE37,314 Under 35 U.S.C. § 271(e)(2) 20.

Derivatives," was duly and legally reissued by the United States Patent and Trademark Office on August 7, 2001. Plaintiffs hold all substantial rights in the '314 patent and have the right to sue for infringement thereof. A true and correct copy of the '314 patent is attached as Exhibit A. 22. On information and belief, Aurobindo Pharma and Aurobindo USA filed ANDA

No. 79-170 in order to obtain approval to market the Aurobindo Rosuvastatin Calcium Tablets in the United States before the expiration of the '314 patent. On information and belief, Aurobindo Pharma and Aurobindo USA also filed with the FDA, pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(IV) and 21 C.F.R. § 314.94(a)(12)(i)(A)(4), a certification alleging that the claims of the '314 patent are invalid. 23. On information and belief, Aurobindo Pharma and Aurobindo USA do not assert

that Aurobindo Rosuvastatin Calcium Tablets are not covered by one or more claims of the '314 patent. 24. Under 35 U.S.C. § 271(e)(2)(A), the submission by Aurobindo Pharma and/or

Aurobindo USA to the FDA of ANDA No. 79-170 to obtain approval for the commercial manufacture, use, or sale of the Aurobindo Rosuvastatin Calcium Tablets before the expiration date of the '314 patent constitutes infringement of one or more claims of the '314 patent, either literally or under the doctrine of equivalents. 25. Plaintiffs will be substantially and irreparably harmed by the infringing activities

described above unless those activities are precluded by this Court. Plaintiffs have no adequate remedy at law. Count II Declaratory Judgment of Infringement of United States Patent No. RE37,314 Under 35 U.S.C. § 271(a) 26. Plaintiffs incorporate by reference paragraphs 1-25 of this Complaint as if fully

set forth herein. 27. Upon information and belief, Aurobindo Pharma and Aurobindo USA have made

substantial preparations to sell Aurobindo Rosuvastatin Calcium Tablets labeled for the same dosages as the Crestor® products. 28. Upon information and belief, Aurobindo Pharma and Aurobindo USA intend to

commence sale of Aurobindo Rosuvastatin Calcium Tablets immediately upon receiving approval from the FDA. 29. The manufacture, importation, sale, and offer for sale of Aurobindo Rosuvastatin

Calcium Tablets, once approved by the FDA, will directly infringe, induce and/or contribute to the infringement of one or more claims of the '314 patent under 35 U.S.C. § 271(a). 30. Plaintiffs will be substantially and irreparably harmed by the infringing activities

described above unless those activities are enjoined by this Court. Plaintiffs have no adequate remedy at law. 31. An actual controversy exists relating to Aurobindo Pharma and Aurobindo USA's

threatened infringement of the '314 patent. PRAYER FOR RELIEF WHEREFORE, Plaintiffs respectfully request that this Court enter judgment in its favor as follows: (1) (2) holding that the claims of the '314 patent are valid and enforceable; holding that the submission of ANDA No. 79-170 by Aurobindo Pharma and/or

Aurobindo USA infringes one or more claims of the '314 patent under 35 U.S.C. § 271(e)(2); (3) declaring that the manufacture, use, offering for sale, or sale of the Aurobindo

1. Field of the Invention The present invention relates to 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor. 2. Prior Art 15 As the first generation of drugs for the treatment of atherosclerosis by inhibiting the activity of HMG-CoA reductase, there are known Mevinolin (U.S. Pat. No. 4,231, 938), pravastatin sodium (U.S. Pat No. 4,346,227), and, simvastatin (U.S. Pat. No. 4,444,784), which are fungal 20 metabolites or of the chemical modifications. Recently, synthetic inhibitors of HMG-CoA reductase such as fluvastatin (F. G. Kathawala et al., 8th Int'l Symp. on Atherosclerosis, Abstract Papers, p. 445, Rome (1988)) and BMY 22089 (GB Pat. No. 2,202,846) are developed as the 25 second generation drugs.

SUMMARY OF THE INVENTION The compounds of the present invention inhibit the HMGCoA reductase, which plays a main role in the synthesis of cholesterol, and subsequently they suppress the biosynthesis of cholesterol. Therefore, they are useful in the treatment of hypercholesterolemia, hyperlipoproteinemia, and atherosclerosis. DETAILED DESCRIPTION The present invention relates to compounds of the formula (I):

Halogen means fluorine, chlorine, bromine and iodine. The term "aryl" refers to C 6 to C 12 aromatic group including phenyl, tolyl, xylyl, biphenyl, naphthyl, and the like. The aryl may have 1 to 3 substituents independently selected from the group consisting of lower alkyl, halogen, amino, and cyano. Preferred aryl is phenyl substituted by 1 to 3 halogens. The term "aralkyl" refers to C 1 to C 6 lower alkyl substituted by C 6 to C 12 aromatic aryl group defined above. Examples of them are benzyl, phenethyl, phenylpropyl and the like, each of which may have 1 to 3 substituents independently selected from the group consisting of lower alkyl halogen, amino, cyano, and the like. The term "a cation capable of forming a non-toxic pharmaceutically acceptable salt" refers to alkali metal ion, alkaline earth metal ion, and ammonium ion. Examples of alkali metal are lithium, sodium, potassium, and cesium, and examples of alkaline earth metal are beryllium, magnesium, and calcium. Especially, sodium and calcium are preferred. Examples of "acyl" are formyl acetyl, propionyl, butyryl, isobutyryl, valeryl, and isovaleryl. In the term "imino which may have a substituent", preferred substituents are acyl, optionally substituted amino, and substituted sulfonyl. The term "substituted amino as substituent" means amino group substituted by sulfonyl and alkylsulfonyl. Examples of them are sulfonyl amino and methanesulfonyl amino. The term "substituted sulfonyl as substituent" means sulfonyl group substituted by alkyl, amino, or alkylamino. Examples of them are methanesulfonyl, sulfamoyl, methylsulfamoyl, and N-methylsulfamoyl. The compounds of the present invention can be prepared by the following method. (1) The carboxylate group of the compound a is converted into the alcohol group by the reduction in an appropriate inactive solvent such as THF, ether, and toluene in the presence of the reductant such as LiAlH and DIBAL-H. The reaction is performed at _70° to 50° c., preferably at near room temperature, for 10 minutes to 10 hours, preferably for 30 minutes to 3 hours. Then the obtained alcohol is subjected to oxidation in an appropriate solvent such as methylene chloride in the presence of the oxidizing agent such as TPAP/4-methylmorpholin-N-oxide or pyridium chlorochromate to give aldehyde compound b. The reaction is performed at 0°_60° c., preferably at near room temperature, for 10 minutes to 10 hours, preferably 30 minutes to 3 hours.

Sprague-Dawley rats, which were in free access to ordinary dietes containing 2% cholestyramine and water for 2 weeks, were used for the preparation of rat liver microsome. The thus obtained microsome was the purified according to the manner by Juroda et al., Biochem. Biophys. Act, 486, 70 (1977). The microsomal fraction obtained by centrifugation at 105,000xg was washed once with a buffered solution containing 15 mM nicotinamide and 2 mM magnesium chloride (in a 100 mM potassium phosphate buffer, pH 7.4). It was homogenized with a buffer containing nicotinamide and magnesium chloride at the same weight as the liver employed. The thus obtained homogenate was cooled down and kept at _80° C.

The reaction mixture is stirred at the same temperature for 2 hours, and the resulting precipitate is collected, washed with

The rat liver microsome sample (100 ,ul), which was preserved at _80° c., was fused at 0° C. and diluted with 0.7 35 ml of a cold potassium phosphate buffer (100 mM, pH7.4). This was mixed with 0.8 ml of 50 mM EDTA(buffered with the aforementioned potassium phosphate buffer) and 0.4 ml of 100 mM dithiothreitol solution (buffered with the aforementioned potassium phosphate buffer), and the mixture 40 was kept at 0° C. The microsome solution (1.675 ml) was mixed with 670 ,ul of 25 mM NADPH (buffered with the aformentioned potassium phosphate buffer), and the solution was added to the solution of 0.5 mM [3- 1 4](HMG-CoA (3mCi/mmol). A solution (5 ,ul) of sodium salt of the test 45 compound dissolved in potassium phosphate buffer is added to 45,u1 of the mixture. The resulting mixture was incubated at 37° C. for 30 minutes and cooled. After termination of the reaction by addition of 10 ,ul of 2N·HCI, the mixture was incubated again at 37° C. for 15 minutes and then 30,u1 of 50 this mixture was applied to thin-layer chromatography of silica gel of 0.5 mm in thickness (MerckAG,Art 5744). The chromatograms were developed in toluene/acetone (1/1) and the spot, whose Rf value was between 0.45 to 0.60, were scraped. The obtained products were put into a vial contain55 ing 10 ml of scintillator to measure specific radio-activity with scintillation counter. The activities of the present compounds are shown in Table 4 as comparative ones based on the assumption that the activity of Mevinolin (sodium salt) as reference drug is 100.
