제1도 및 제2도는 각각 본 발명에 따르는 구조식(1)의 결정성 세프타지딤 비스하이드로요오다이드 모노하이드레이트 화합물의 X-선 분말회절 스펙트럼 및 IR 스펙트럼을 나타낸다.1 and 2 respectively show the X-ray powder diffraction spectrum and the IR spectrum of the crystalline ceftazidime bishydroiodide monohydrate compound of formula (1) according to the present invention.

본 발명은 다음 구조식(1)로 표시되는 신규한 결정성 세팔로스포린 화합물인 세프타지딤 비스하이드로요오다이드 모노하이드레이트 및 그의 제조 방법에 관한 것이다.The present invention relates to a ceftazidime bishydroiodide monohydrate, which is a novel crystalline cephalosporin compound represented by the following structural formula (1), and a preparation method thereof.

세프타지딤은 화학명이 (6R,7R)-7-[(Z)-2-(2-아미노티아졸-4-일)-2-(2-카르복시프로프-2-옥시이미노)아세트아미도]-3-(1-피리디늄메틸)세프-3-엠-4-카르복실레이트인 공지의 항생물질로서 영국특허 명세서 제2025398호에 기술되어 있는 바와같이, 광범위한 항균활성, 특히 녹농균(Pseudomonas)균주를 포함한 그람 음성균엔 대해 탁월하게 높은 항균 활성을 나타내는 것으로 알려져 있다.Ceftazidime has the chemical name (6R, 7R) -7-[(Z) -2- (2-aminothiazol-4-yl) -2- (2-carboxyprop-2-oxyimino) acetamido ] -3- (1-pyridiniummethyl) sef-3-m-4-carboxylate, as described in British Patent No. 2025398 as a known antibiotic, a broad spectrum of antimicrobial activity, in particular Pseudomonas Gram-negative bacteria, including strains, are known to exhibit exceptionally high antimicrobial activity.

이러한 세프타지딤 항생물질의 유도체중의 하나로, 영국특허 명세서 제2063871A호에 기술돈 결정성 세프타지딤 펜타하이드레이트는 저장안정성이 우수하여 주사제로서의 제형하에 이용되고 있다. 이러한 안정한 결정성 세프타지딤 펜타하이드레이트의 제조에는 지금까지 주로 비스하이드로클로라이드나 비스하이드로브로마이드 중간체를 경유하는 다수의 방법이 이용되어 왔다.As one of such derivatives of ceftazidime antibiotics, crystalline ceftazidime pentahydrate described in British Patent No. 2063871A is used in a dosage form as an injection because of its excellent storage stability. Many methods have been used to prepare such stable crystalline ceftazidime pentahydrates, mainly via bishydrochloride or bishydrobromide intermediates.

예를들어, 영국특허 명세서 제2,063,871A호에는 이중차단된 세프타지딤 용매화물에 포름산 및 염산을 반응시켜 세프타지딤 비스하이드로클로라이드를 제조하고, 여기에 염기를 반응시켜 pH 3.5 내지 4.2로 조절 하여 세프타지딤 펜타히이드레이트를 제조하는 방법이 기술되어 있다.For example, British Patent Specification No. 2,063,871A prepares ceftazidime bishydrochloride by reacting double-blocked ceftazidime solvate with formic acid and hydrochloric acid, and reacts with a base to adjust pH to 3.5 to 4.2. A method for preparing ceftazidime pentahydrate is described.

한편, 대한민국 특허 공보 제87-829호에는 이중차단된 세프타지딤을 포름산 및 HBr과 반응시켜 세프타지딤 비스하이드로브로마이드 α-모노하이드레이트를 얻고 염기와 반응시켜 pH 3.5 내지 4.0으로 조절하여 세프타지딤 펜타하이드레이트를 제조하는 방법이 기술되어 있다.Meanwhile, Korean Patent Publication No. 87-829 discloses a ceftazidime bishydrobromide α-monohydrate by reacting a double-blocked ceftazidime with formic acid and HBr, and reacted with a base to adjust the pH to 3.5 to 4.0 ceftazidime. A method of making pentahydrate is described.

또 다른 방법으로 유럽특허 명세서 제1079546A2호에는 이중 차단된 세프타지딤을 포름산 및 염산과 반응시키고 2상계를 형성시킨 다음 중간체를 분리하지 않고 수성층의 pH를 약 3.5 내지 4.5로 조절하여 세프티지딤 펜타하이드레이트를 결정화시키는 방법이 기술되어 있다.In another method, EP 1079546A 2 discloses a ceftazidime by reacting a double blocked ceftazidime with formic acid and hydrochloric acid, forming a biphasic system, and adjusting the pH of the aqueous layer to about 3.5 to 4.5 without separating intermediates. A method of crystallizing pentahydrate is described.

또한 유럽특허 명세서 제0267427A1호 및 WO 제88-02752호에도 세프타지딤 펜타하이드레이트의 제조방법이 기술되어 있는데, 이에 따르면 단일 차단된 세프타지딤에 염산을 작용시켜 용액을 형성시킨 다음 직접 염기를 작용시켜 세프타지딤 펜타하이드레이트를 형성시키기거나, 중간체로서 결정성 세프타지딤 비스하이드로클로라이드를 단리해낸 후 여기에 염기를 반응시켜 결정화시킴으로써 세프타지딤 펜타하이드레이트를 제조한다.European Patent Specification No. 0267427A 1 and WO 88-02752 also describe a process for the preparation of ceftazidime pentahydrate, whereby a single blocked ceftazidime is reacted with hydrochloric acid to form a solution and then directly The ceftazidime pentahydrate is prepared by acting to form ceftazidime pentahydrate or by isolating crystalline ceftazidime bishydrochloride as an intermediate and then reacting it with a base to crystallize.

한편, 유럽특허 명세서 제0187450A2에는 불순물을 함유하고 있는 세프타지딤의 정제방법으로 세프타지딤 함유 용액 pH를 5.5 내지 6.5로 조절한 다음에 산을 가하여 pH 4.0 내지 4.7로 조절함으로써 결정성 세프타지딤 펜타하이드레이트를 얻는 방법도 기술되어 있다.On the other hand, European Patent Specification No. 087450A 2 is a method for purifying ceftazidime containing impurities to adjust the pH of the ceftazidime solution to 5.5 to 6.5 and then to the pH to 4.0 to 4.7 by the addition of crystalline ceftage A method of obtaining dim pentahydrate is also described.

즉, 상기방법들에 따르면 세프타디딤 펜타하이드레이트를 제조하기 위해서는 이중 또는 단일 차단된 세프타지딤을 탈차단 시켜서 중간체로서 세프타지딤 비스하이드로클로라이드나 세프타지딤 비스하이드로브로마이드를 제조한 다음 여기에 염기를 작용시키거나, 탈차단된 반응 용액에 직접 염기를 가하여 결정화 시키는 방법을 사용하였다.That is, according to the above methods to prepare ceftadidim pentahydrate by deblocking double or single blocked ceftazidime to prepare ceftazidime bishydrochloride or ceftazidime bishydrobromide as intermediate, Or crystallization by adding a base directly to the deblocked reaction solution.

그라나 상기 방법들에 따라 비스하이드로클로라이드나 비스하이드로브로마이드를 경유하여 세프타지딤 펜타하이드레이트를 제조하는 경우에는 차단 및 탈차단 반응이 필요하고 전체적인 반응공정이 길어지므로 인해 목적물인 펜타하이드레이트의 수율이 저조한 단점이 있었으며, 중간체로서 세프타지딤 비스하이드로클로라이드나 세프타지딤 비스하이드로브로마이드는 저장안정성 면에서 만족할만한 결과를 제공하지 못하였다.However, in the case of preparing ceftazidime pentahydrate via bishydrochloride or bishydrobromide according to the above methods, blocking and deblocking reactions are required, and the overall reaction process is lengthened. Ceftazidime bishydrochloride or ceftazidime bishydrobromide as intermediates did not provide satisfactory results in terms of storage stability.
