【배경 기술】 [Background technology]
D-카이로-이노시틀 (D-chi ro-inositol, c i s— 1, 2 , 4_t rans-3 ,5,6- cyclohexol)은 마이오一이노시를 (myo— inositol , cis一 l,2,3,5—trans— 4,6一 cyclohexanehexol)의 스테레오이소머로서 3 번 하이드록실 그룹이 에피머화 된 형태이다 (도 1). D-카이로ᅳ이노시를은 이노시를 포스포글리칸 (IPG)의 주요 구성성분으로 인슐린 신호전달의 증요한 매개체로 보고되어 있으며, 제 2 형 당뇨의 치료에 효과가 있다고 알려져 있다. D-카이로 -이노시를은 주로 진핵생물에서 발견되며, 마이오 -이노시틀의 에피머화에 의해 생합성된다. D-카이로 -이노시를은 주로 피니를 (D— pinitol)이나 카스가마이신 (kasugamycin)의 염산 가수분해에 의해 생산하고 있다 (U.S. Pat No. 5827896, U.S. Pat No. 5091596, U.S. Pat No. 5463142, U.S. Pat No.5714643). 그러나, 원료인 피니를이나 카스가마이신이 고가이며, 유기합성법 (U.S. Pat No. 5406005, W0 96/25381)도 알려져 있으나, 부산물의 분리가 용이하지 않아 경제성이 낮다. D-카이로ᅳ이노시를은 마이오-이노시를로부터 이노시를 디하이드로게나아제 (inositol dehydrogenase) 및 이노소스 이소머라아제 ( inosose isomerase) 효소의 연속작용에 의해 생성될 수 있으며, 상기 효소를 마이오 -이노시를에 직접 반웅시키거나, 상기 효소를 발현하도록 형질전환된 재조합 세포를 이용한 발효 방법에 의해 생산될 수 있다. 그러나, 상기 발효방법 또는 효소반응법을 통해 생산된 반웅생성물에는 마이오—이노시를과 D-카이로- 이노시를이 흔합되어 있고, 흔합용액중에는 마이오ᅳ이노시를에 비해 D- 카이로 -이노시를의 농도가 상대적으로 낮다. 따라서, 마이오 -이노시를과D-chiro-inositol (cis— 1, 2, 4_t rans-3, 5,6-cyclohexol) is used for myo-inositol, cis 一 l, 2, 3,5—trans — 4,6 cyclo cyclohexanehexol) is a stereoisomer of the 3 hydroxyl group is epimerized (Fig. 1). D-Cyrropyinosinos is reported to be an important mediator of insulin signaling as an important component of phosphoglycans (IPG) and is known to be effective in the treatment of type 2 diabetes. D-Cyro-inosyl is primarily found in eukaryotes and is biosynthesized by epimerization of myo-inositol. D-Cyro-inosyl is mainly produced by hydrochloric acid hydrolysis of D-pinitol or kasugamycin (US Pat No. 5827896, US Pat No. 5091596, US Pat No. 5463142). , US Pat No. 5714643). However, although raw materials such as pinir and kasugamycin are expensive, and organic synthesis method (US Pat No. 5406005, WO 96/25381) is known, it is not easy to separate by-products and thus it is economically low. D-chiroybinosinos may be produced from myo-inosyl by the continuous action of inositol dehydrogenase and inosose isomerase enzymes. It can be produced by fermentation methods using recombinant cells transformed directly with Myo-Inosi, or transformed to express the enzyme. However, in the reaction product produced by the fermentation method or the enzyme reaction method, myo-inosino and D-chiro-inosino are mixed, and the mixed solution contains myo-inosino-D. The concentration of Cairo-inos is relatively low. Thus, with the Maio-Inoshi

Precipitation of myo-inos and D-chiro-inos is induced by the addition of the organic solvent. The precipitation rate of myo-inos and D-chiro-inos is increased by the addition of organic solvent, but compared to D-chiro-inos The precipitation rate of myo-inos is much greater (see Figure 5). Therefore, by adding an organic solvent to the mixed solution of myo-inosino and D-chiro-inosino, D-chiro-inosio is precipitated in a higher amount than that of D-chiro-inosio. Can increase the concentration of D-Cairo-Inosino.

■ 이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하고자 한다. 이들 실시예는 오로지 본 발명을 보다 구체적으로 설명하기 위한 것으로, 본 발명의 요지에 따라 본 발명의 범위가 이들 실시예에 의해 제한되지 않는다는 것은 당업계에서 통상의 지식을 가진 자에 있어서 자명할 것이다. 실시예 실시예 1: 마이오 -이노시를과 D-카이로 -이노시를의 용해도 측정 마이오-이노시를 (myo-inositol, Ml)과 D-카이로-이노시를 (D-chiro- inositol, DCI)의 용해도를 측정하였다. 먼저 마이오 -이노시를과 D- 카이로 -이노시를올 상온 (약 25°C)에서 1차 증류수에 각각 59 (w/v) 내지 80%(w/v)의 농도가 되도록 용해시켰다. 각 용액에서 용해되지 않고 침전된 부분을 원심분리를 통하여 분리하고 이노시를이 완전히 용해된 상층액 부분을 취하여 각각의 농도를 HPLC로 분석하였다. 분석조건은 HPLC(Shimadzu LClOAvp)를 이용하여 , Kromasil 5NH2 칼럼 (4.6 麵 X 250瞧), 이동상 75% 아세토니트릴, 칼럼 온도 40°C, RI 검출기를 이용하였다. 그 결과는 도 3에 나타내었다. 마이오-이노시를 (Ml)의 용해도는 25°C에서 약 15%(w/v)로 나타났으며, D—카이로—이노시를 (DCI)의 경우 약 55%(w/v) 전후로 나타나, 마이오 -이노시를과 D-카이로 -이노시를의 용해도 차이가 매우 큰 것으로 확인하였다. 실시예 2: D-카이로-이노시를의 고순도 정제를 위한 1차 에탄올 처리 마이오 -이노시를과 D-카이로 -이노시틀의 흔합액은 마이오 -이노시를을 기질로하여 D-카이로 -이노시를을 생산하는 다양한 방법을 통해 얻어진다. 예를 들어, 마이오-이노시를 트랜스포터 (myo-inositol transporter), 이노시를 디하이드로게나아제 (inositol dehydrogenase) 및 이노소스 이소머라아제 (inosose isomerase)를 발현하도록 형질전환된 재조합 세포를 기질인 마이오 -이노시를을 포함하는 배지에서 배양하는 경우 배양한 배지에는 반웅하고 남은 마이오 -이노시를과 반웅 생성물인 D—카이로- 이노시를이 흔합된 이노시를 흔합용액이 만들어진다. 또한, 상기 효소를 발현하도록 형질전환된 재조합 세포의 휴면세포를 마이오 -이노시를을 포함하는 최소배지에서 접종하여 마이오 -이노시를을 으카아로 -이노시를로 전환하는 방법의 경우에도 배양한 최종 배양 산물에 반웅하고 남은 마이오- 이노시를과 반웅 생성물인 D-카이로 -이노시틀의 이노시를 흔합물이 만들어진다. 또한, 마이오-이노시를 트랜스포터, 이노시를 디하이드로게나아제 및 이노소스 이소머라아제의 효소를 사용하여 기질인 마이오-이노시를로부터 D-카이로 -이노시를을 생성시키는 효소 반응방법의 반웅을 완료한 최종 반웅산물에 반웅하고 남은 마이오—이노시를과 D- 카이로 -이노시를이 흔합된 흔합 용액이 만들어진다. 상기 D—카이로- 이노시를의 제조방법에서 반웅 생성물내의 생성물인 으카이로 -이노시를의 최종 평형 농도는 약 14%이므로, 마이오—이노시를과 D-카이로—이노시를의 최종 반응 흔합물에서 마이오 -이노시를과 D-카이로 -이노시를은 약 86 :14의 비율로 존재한다. 마이오-이노시를로부터 으카이로 -이노시를을 생성하는 반응전의 반웅액 내에서 기질인 마이오 -이노시를은 물에 대한 용해도를 고려할 때 약 150 g/L의 농도로 포함되며, 반응 완료후 반응 생성물에는 129g/L의 마이오 -이노시를과 21g/L의 D-카이로 -이노시를이 포함되어 있다. 이노시를의 흔합액은 재조합 세포를 사용한 발효방법인 경우 발효가 완료된 완전배지, 예를 들어 TB (terrific broth)일 수 있으며, 휴면세포를 이용한 전환법인 경우 M9 최소배지 또는 식염수일 수 있으며 , 효소반웅법인 경우 효소반응의 완충액이 될 수 있다. 이와 같은 다양한 반웅액의 조성에서 에탄올을 첨가하여 마이오-이노시를 (Ml)과 D-카이로-이노시를 (DCI)의 분리를 시험하였다. 발효방법의 경우를 실험하기 위해서 0.5%(w/v) 락토오스, 12.9%(w/v) 마이오 -이노시를, 2.1%(w/v) D-카이로ᅳ이노시를을 첨가한 TB 배지 [terrific broth, 1.2% (w/v) 트립톤, 2.4% 효모추출물, 0.4% 글리세롤, 0.Γ7Μ K2HP04, 0.72M H2P04]를 사용하였다. 휴면세포 전환법의 경우를 실험하기 위해서 0.5% (w/v) 락토오스, 12.9% (w/v) 마이오 -이노시를, 2.1% (w/v) D-카이로 -이노시를을 첨가한 M9 최소배지 [6.4%(w/v) Na2HP04.7H20, 1.5% (w/v) KH2P04 , 0.25% (w/v) NaCl , 0.5% (w/v) NH4C1 , 2 mM MgS04, 0.1 mM CaCl2]와, 0.5% (w/v) 락토오스, 12.9% (w/v) 마이오 -이노시를, 2.1% (w/v) D-카이로—이노시를을 첨가한 식염수 (0.85% NaCl)를 사용하였다. 효소반웅법의 경우를 실험하기 위해서 50 mM Tris-HCl (pH8.0), 1 mM MgS04, 0.1 mM MnS04, 0.5 mM NAD의 조성의 반웅 완충액에 12.9% (w/v) 마이오 -이노시를, 2.1% (w/v) D-카이로- 이노시를을 첨가하여 사용하였다. 대조구로서는 12.9%(w/v) 마이오- 이노시를, 2.1%(w/v) D-카이로 -이노시를이 포함된 증류수를 사용하였다. 상기 제조한 이노시를 흔합액에 에탄올을 가하여, 이노시를 흔합액:에탄올의 비율이 각각 10:0, 9:1(0.11배), 8:2(0.25배), 7:3(0.43배), 6:4(0.67배), 5:5(1배), 4:6(1.5배), 3:7(2.33배), 2:8(4배), 1:9(9배)로 되도록 하여 완전히 흔합한 후 실온 (약 25°C)에서 1시간 동안 진탕하였다. 이를 3,500 rpm 에서 30분간 원심분리한 후 상층액을 취하여 HPLC로 마이오 -이노시를과 으카이로 -이노시를의 농도를 분석하였다. HPLC분석 방법은 실시예 1에서 설명된 방법과 같다. 분석한 결과는 도 4, 도 5 및 도 6에 나타내었다. ■ Hereinafter, the present invention will be described in more detail with reference to the following examples. These examples are only for illustrating the present invention more specifically, it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples in accordance with the gist of the present invention. . EXAMPLES Example 1 Determination of Solubility of Myo-inosyl and D-Cyro-inosyl Myo-inositol (Mo) and D-chiro-inositol (D-chiro-inositol) , Solubility of DCI) was measured. First, myo-inosino and D-chiro-inosiol were dissolved in primary distilled water at room temperature (about 25 ° C.) to a concentration of 59 (w / v) to 80% (w / v), respectively. The undissolved portions in each solution were separated by centrifugation and each concentration was analyzed by HPLC, taking the supernatant portion in which the inos were completely dissolved. Analytical conditions were performed using HPLC (Shimadzu LClOAvp), Kromasil 5NH2 column (4.6 x 250 cc), mobile phase 75% acetonitrile, column temperature 40 ° C, RI detector. That The results are shown in FIG. The solubility of myo-inosyl (Ml) was found to be about 15% (w / v) at 25 ° C, and D-chiro-inosyl was about 55% (w / v) for (DCI). It was confirmed that the difference in solubility between myo-inos and D-chiro-inosio was very large. Example 2 Primary Ethanol Treatment for High Purity Purification of D-Cyro-Inosyl A mixture of Myo-Inosyl and D-Cairo-Inosyl was prepared using D-Cyro-Inosio as a substrate. It is obtained through various methods of producing Cairo-Inosi. For example, substrates of recombinant cells transformed to express myo-inositol transporter, inosi dehydrogenase and inosose isomerase When culturing in a medium containing phosphorus myo-inosity, a mixed solution is prepared in which the ino-sidium mixed with the remaining myo-inosine and the reaction product D—Cairo-inosino are mixed. In addition, in the case of the method of inoculating the dormant cells of the recombinant cells transformed to express the enzyme in a minimal medium containing myo-inosi to convert myo-inosi to ekaa-inosi A mixture is formed between the remaining myo-inos and the inos of D-Cairo-inositite, the reaction product of the final culture product. In addition, an enzyme reaction for generating D-chiro-inosine from myo-inosity, which is a substrate, by using a myo-inosity transporter, an inosine dehydrogenase, and an enzyme of inososomerase After the reaction of the method was completed, the resultant reaction product was produced by mixing the remaining Maio-Inos and D-Cairo-Inos. Since the final equilibrium concentration of the product in the reaction product of the Cairo-Inosyl D-Cairo-Inosyl is about 14%, the final reaction of the Myo-Inosyl and D-Cairo-Inosyl In the mixture, myo-inos and D-chiro-inos are present at a ratio of about 86:14. Myo-inosyl substrate, which is a substrate in the reaction solution to generate E. coli-Inosio from myo-inosyl, is included at a concentration of about 150 g / L, considering the solubility in water. Upon completion the reaction product contains 129 g / L of myo-inosyl and 21 g / L of D-chiro-inosyl. The mixture of Inosul is a fermentation method using a recombinant cell. It may be complete medium, for example TB (terrific broth), in the case of dormant cell conversion method may be M9 minimal medium or saline, in the case of enzyme reaction method may be a buffer of the enzyme reaction. The separation of myo-inosyl (Ml) and D-chiro-inosy (DCI) was tested by adding ethanol in the composition of these various reaction solutions. TB medium containing 0.5% (w / v) lactose, 12.9% (w / v) myo-inosity, and 2.1% (w / v) D-chirobinosinos for the fermentation method. [terrific broth, 1.2% (w / v) tryptone, 2.4% yeast extract, 0.4% glycerol, 0.Γ 7Μ K 2 HP0 4 , 0.72MH 2 P0 4 ] was used. To test the case of dormant cell conversion, 0.5% (w / v) lactose, 12.9% (w / v) myo-inosity and 2.1% (w / v) D-chiro-inosity were added. M9 minimal medium [6.4% (w / v) Na 2 HP0 4 .7H 2 0, 1.5% (w / v) KH 2 P0 4, 0.25% (w / v) NaCl, 0.5% (w / v) NH 4 C1, 2 mM MgS0 4 , 0.1 mM CaCl 2 ], 0.5% (w / v) lactose, 12.9% (w / v) myo-inos, 2.1% (w / v) D-Cairo-inos Saline (0.85% NaCl) to which was added was used. To test the case of enzyme reaction, 12.9% (w / v) myo-ino in reaction mixture of 50 mM Tris-HCl (pH8.0), 1 mM MgSO 4 , 0.1 mM MnSO 4 , 0.5 mM NAD The city was used with the addition of 2.1% (w / v) D-Cyro-inosi. Distilled water containing 12.9% (w / v) myo-inosi and 2.1% (w / v) D-chiro-inosi was used as a control. Ethanol was added to the prepared inosin mixture, and the inosin mixture was 10: 0, 9: 1 (0.11 times), 8: 2 (0.25 times), 7: 3 (0.43 times), respectively. ), 6: 4 (0.67x), 5: 5 (1x), 4: 6 (1.5x), 3: 7 (2.33x), 2: 8 (4x), 1: 9 (9x) After complete mixing it was shaken for 1 hour at room temperature (about 25 ° C). After centrifugation at 3,500 rpm for 30 minutes, the supernatant was collected, and the concentrations of myo-inosyl and eucairo-inosyl were analyzed by HPLC. HPLC analysis method is the same as described in Example 1. The analysis results are shown in FIGS. 4, 5, and 6.
도 4는 각 이노시를 흔합액에 에탄을 첨가한 후 생성된 침전물을 제거하여 얻은 상층액내에 남아있는 마이오 -이노시를과 D-카이로ᅳ 이노시틀의 농도를 나타낸 것이다. 마이오 -이노시를의 경우, 모든 배지 조건에서 에탄올 첨가량에 따라 농도가 빠르게 감소하여, 약 1 배수의 에탄을을 첨가한 경우 마이오 -이노시를은 초기 126 g/L 농도로부터 약 99 g/L이 침전되어 약 27 g/L의 마이오 -이노시를이 남아 있는 것으로 나타났다. 이에 비해, D-카이로 -이노시를의 감소량은 매우 낮아서 약 1 배수의 에탄을을 첨가하면 초기 17 g/L의 농도에서 15 g/L으로 감소되어 약 2 g/L만이 침전되는 것으로 나타났다. FIG. 4 shows the concentrations of myo-inosyl and D-chirojan inositol remaining in the supernatant obtained by adding ethane to the respective mixtures of ethane. In the case of myo-inosyl, the concentration decreased rapidly according to the amount of ethanol added under all medium conditions, and the myo-inosine was approximately 99 from the initial 126 g / L concentration when about 1 multiple of ethane was added. g / L precipitated, leaving about 27 g / L of myo-inosyl. In comparison, the decrease in D-Cyro-Inosi was very low, and the addition of about 1 multiple of ethane reduced to 15 g / L at the initial concentration of 17 g / L, leaving only about 2 g / L of precipitation.
상기 도 4에 나타난 결과를 침전율로 환산하여 도 5에 나타내었다. 마이오 -이노시를의 침전율은 에탄올 첨가량에 따라 급격히 증가하였으며 , 1 배수의 에탄올을 첨가하였을 때 모든 반응액 조건에서 비교적 유사하게 70- 80%의 침전율올 보였고, 약 2.5 배 이상의 에탄을 첨가 조건에서는 대부분의 마이오 -이노시를이 침전되는 것을 확인하였다. 이에 반하여 D- 카이로 -이노시를의 침전율은 배지조건에 따라서 약간 다르게 나타났다. 약 1 배의 에탄을을 첨가할 때까지는 비교적 유사하게 전체적으로 약 15% 이하의 침전율을 보였으나, 1.5 배 이상의 에탄올을 첨가한 경우 물, 식염수, 효소반웅 완층액의 경우보다 M9 배지와 TB 배지에서 침전율이 급격하게 증가하는 양상을 보였다. 이러한 양상은 각 용액에 포함된 염 (salt)의 양이 다르기 때문인 것으로 판단되는데 , 물, 식염수, 효소반웅 완충액에 함유되어있는 염의 양에 비해 M9 배지와 TB 배지에 함유된 염의 양이 더 많기 때문인 것으로 보인다. The result shown in FIG. 4 is shown in FIG. 5 in terms of precipitation rate. The precipitation rate of myo-inosi increased rapidly with the amount of ethanol, and when 1-fold ethanol was added, the precipitation rate of 70-80% was relatively similar in all reaction conditions. In most of the myo-inosity was confirmed to precipitate. In contrast, the precipitation rate of D-Cairo-inosyl was slightly different depending on the medium conditions. Until the addition of about 1-fold ethane, the sedimentation rate was about 15% or less in total.However, when 1.5-fold or more ethanol was added, it was found in M9 and TB media more than water, saline, and enzyme reaction complete solution. The precipitation rate increased rapidly. This may be due to the different amounts of salt in each solution, since the amount of salt in M9 and TB medium is higher than in water, saline and enzyme reaction buffer. Seems to be.
상기 도 4 및 도 5에 나타난 실험 결과를 토대로 D-카이로- 이노시를의 순도를 계산하여 도 6에 나타내었다. D-카이로 -이노시를의 순도는 1 배수의 에탄올을 첨가하였을 경우 모든 종류의 배양액에서 35- 40% 정도로 나타났으며, 그 이상의 양의 에탄을을 첨가하면 순도가 증가하지만, D-카이로 -이노시틀의 손실율이 커지게 된다. 이상의 결과를 종합하면 약 1 배수의 에탄올을 첨가할 경우 모든 종류의 배양액 조건에서 약 80%의 마이오 -이노시톨이 침전되고, 이때 D-카이로 -이노시를의 침전율, 즉 손실율은 15% 이하로 나타났으몌 초기 14% 정도이었던 D-카이로- 이노시를의 순도를 약 3으40%로 증가시킬 수 있었다. 에탄을 첨가량이 1 배수를 초과할 경우 D-카이로 -이노시를의 침전율 (손실율)이 급격히 증가므로, 약 1 배수의 에탄올을 첨가하는 경우 D—카이로 -이노시를의 손실율을 최소로 하면서 마이오 -이노시를을 침전시켜 분리 및 제거할 수 있을 것으로 기대된다. 상기한 실험에서 이노시를이 흔합된 배양액에 대하여 약 1 배수의 에탄올을 첨가하여 침전시켰을 경우 마이오 -이노시를과 D-카이로 -이노시틀의 비율은 약 63:37 정도인 것으로 나타났다. 실시예 3: 1차 에탄을 처리 후 상층액의 농축 건조 및 재용해 상기 실시예 2에서 설명된 방법과 같이, 이노시틀 흔합액에 동량 (1:1)의 에탄올을 흔합한 후 침전물을 제거하여 얻은 상층액을 8(rc로 가열하고' 진공 상태에서 농축 및 건조하였다. 건조후 얻은 이노시를의 건조 분말 (마이오ᅳ이노시를과 D-카아로 -이노시를의 흔합 분말)을 15% - 70%의 다양한 농도로 증류수에 용해시켜 각 농도에서의 마이오 -이노시를과 D-카이로 -이노시를의 용해 특성을 관찰하였다. HPLC를 아용한 이노시를의 분석 방법은 실시예 1에서 설명된 내용과 동일하다. 마이오 -이노시를과 D- 카이로 -이노시를의 용해특성을 분석한 결과는 도 7에 나타내었다. Based on the experimental results shown in FIGS. 4 and 5, the purity of D-Cairo-Inosyl is calculated and shown in FIG. 6. The purity of D-Cyro-Inosyl was found to be about 35-40% in all cultures when 1-fold ethanol was added. The loss ratio of the ino-seattle will increase. Taken together, about 1% of ethanol is added and about 80% of myo-inositol is precipitated under all kinds of culture conditions. It was found that the initial purity of D-Cairo-Inoshil, which was about 14%, could be increased to about 3-40%. If the amount of ethane added exceeds 1, the precipitation rate (loss rate) of D-Cyro-Inosyl is rapidly increased, and when about 1 multiple of ethanol is added, the loss of D-Cyro-Inosyl is minimized. It is expected that OH-Inosi can be separated and removed by precipitation. In the above experiments, when Inosi was precipitated by adding about 1 multiple of ethanol to the mixed culture solution, The ratio of D-Cairo-inositole was found to be about 63:37. Example 3: Concentration drying and re-dissolution of the supernatant after treatment with primary ethane, the same amount (1: 1) of ethanol was mixed in the inositol mixture as described in Example 2, and then the precipitate was removed. the supernatant obtained was heated at 8 (rc, concentrated and dried in a "vacuum-dried powder of the Inno when obtained after drying (Maio the eu Ino when a D- and Carr-heunhap the powder of the Inno-shi) The dissolution characteristics of myo-inosyl and D-chiro-inosyl were observed at each concentration by dissolving in distilled water at various concentrations of 15% to 70%. Same as described in Example 1. The results of analyzing the dissolution characteristics of myo-inosyl and D-chiro-inosyl are shown in FIG.
도 7의 패널 A는 각 농도별 용액의 상층액 농도, 즉 용해도를 나타낸 것으로 마이오 -이노시를의 용해도의 경우 상기 실시예 2에서 나타난 바와 같이 약 15% 이상으로는 더 증가하지 않는 것을 확인할 수 있었다. 한편, D-카이로 -이노시를의 경우 용해도가 약 55%이므로 건조분말을 70% 농도로 용해시킨 경우에서도 모든 D-카이로—이노시를이 용해된 것을 확인할 수 있었다. 마이오 -이노시를과 D-카이로 -이노시를의 용해특성을 용해도와 침전율로 표시한 결과는 각각 도 7의 패널 B와 패널 C에 나타내었다. 마이오 -이노시를은 약 20% 용액부터 용해도가 감소하기 시작하여 용액의 농도가 증가할수록 계속적으로 감소하였고, 침전율은 용액의 농도가 증가함에 따라 증가하였다ᅳ D-카이로 -이노시를의 경우 용해도는 용액의 농도가 70%인 경우에 이르기까지 100%을 유지하였으며, 이에 따라 침전율도 0%로서 전혀 침전되지 않는 것으로 나타났다. 결론적으로 최대 70% 용액올 제조하는 경우 마이오 -이노시를은 약 13% 만이 용해되었고, D-카이로 -이노시를은 모두 용해되었다. 이때 D—카이로 -이노시를의 경우 순도는 약 73% 정도인 것으로 측정되었다 (도 7의 패널 D). 실시예 4: 2차 에탄올 처리에 따른 정제 특성 Panel A of FIG. 7 shows the supernatant concentration, that is, the solubility of the solution at each concentration, and it was confirmed that the solubility of the myo-inosi did not increase more than about 15% as shown in Example 2 above. Could. On the other hand, in the case of D-Cyro-Inosyl, solubility is about 55%, even when the dry powder was dissolved at a concentration of 70%, all of the D-Cyro-Inosy was dissolved. The solubility and precipitation rate of the myo-inosino and D-chiro-inosino are shown in panel B and panel C of FIG. The solubility of myo-inosine began to decrease from about 20% of the solution, and then decreased as the concentration of the solution increased, and the precipitation rate increased with increasing concentration of the solution. The solubility was maintained at 100% until the concentration of the solution was 70%, so that the precipitation rate was 0%, indicating no precipitation at all. In conclusion, only about 13% of myo-inosity was dissolved and all of D-Cyro-inosity was dissolved when up to 70% solution was prepared. In this case, the purity of the D—Cairo-Inoshiro was measured to be about 73% (Panel D of FIG. 7). Example 4: Purification Characteristics by Secondary Ethanol Treatment
실시예 3에서 제조한 각 농도별 흔합용액에서 마이오 -이노시를에 대한 포화용액, 즉, 마이오 -이노시를이 충분히 침전되기 시작하는 농도인 35% 이상이 되는 농도의 각 용액에 에탄올을 첨가량을 달리하여 첨가하였다. 에탄을 첨가 후 침전물은 원심분리를 통하여 제거하고 상층액에 존재하는 이노시를을 HPLC를 이용하여 분석하였다. HPLC를 이용한 분석 방법은 실시예 1의 방법과 동일하였다. 이노시를 농도를 분석한 결과는 도 8에 나타내었다. Ethanol was added to each solution having a concentration of 35% or more, which was a concentration at which the saturated solution for myo-inosine, that is, the myo-inosine, began to sufficiently precipitate in the mixed solution for each concentration prepared in Example 3. By varying the amount Added. After addition of ethane, the precipitate was removed by centrifugation and the inos present in the supernatant were analyzed by HPLC. The analysis method using HPLC was the same as that of Example 1. The results of analyzing the concentration of inos are shown in FIG. 8.
도 8의 패널 A는 상층액 중의 마이오-이노시를 농도를 나타낸 것이며, 마이오 -이노시를의 용해도가 15%를 넘지 않으므로 에탄올을 첨가함에 따라 마이오 -이노시를이 침전되는 양상을 보여주고 있다. 에탄을을 첨가함에 따라 마이오 -이노시를의 농도가 급격히 감소하며, 2 배수의 에탄을 첨가시 많은 양의 마이오 -이노시를이 제거된 것을 확인할 수 있었다. 65% 및 70% 농도 용액의 경우 1 배수의 에탄을을 첨가한 경우 마이오ᅳ이노시를이 제거되기 시작하였고, 이보다 낮은 농도의 용액의 경우에도 1.5 배의 에탄올을 첨가함에 따라 마이오 -이노시를이 제거되기 시작함을 확인하였다. 도 8의 패널 B은 D-카이로ᅳ이노시를의 상층액내의 농도를 나타낸 것이며, D-카이로—이노시를의 경우에도 적은 양의 에탄을이 첨가되면서 급격히 침전되는 것으로 나타났다. 마이오ᅳ이노시를에서와 마찬가지로 65% 및 70% 농도 용액의 경우 1 배수의 에탄을부터 D-카이로 -이노시를이 침전되기 시작하였고, 1.5 배수의 에탄을에서 대부분의 침전이 일어났다. 용액의 농도가 낮을 경우, 즉 35% 또는 40%에서는 침전의 정도가 미약하였으나, 약 2 배의 에탄올을 첨가하면서부터는 고농도의 용액에서와 비슷한 수준으로 침전이 일어남을 확인하였다. Panel A of FIG. 8 shows the concentration of myo-inosity in the supernatant, and the solubility of myo-inosine does not exceed 15%. Is showing. As the ethane was added, the concentration of myo-inosine decreased drastically, and it was confirmed that a large amount of myo-inosine was removed when 2 ethane was added. In the case of 65% and 70% solutions, the addition of 1-fold of ethane started to remove myoininosi. It was confirmed that the poem began to be removed. Panel B of FIG. 8 shows the concentration in the supernatant of D-chiro-inosino, and even in the case of D-chiro-inosino, a small amount of ethane was added to precipitate rapidly. As with myoininosity, D-Cyro-Inosi began to precipitate from 1-fold ethane for 65% and 70% -concentration solutions, and most precipitation occurred from 1.5-fold ethane. When the concentration of the solution was low, that is, the degree of precipitation was weak at 35% or 40%, but it was confirmed that precipitation occurred at a level similar to that of the high concentration solution from the addition of about 2 times of ethanol.
상기 실험결과로부터 마이오 -이노시를과 D-카이로—이노시를이 함께 고농도로 존재하는 경우에는 에탄올을 첨가하여 마이오-이노시를로부터 D- 카이로 -이노시를을 분리하는 것이 용이하지 않다는 것을 알 수 있었다.

Therefore, it was confirmed that the purity of D-Cyro-inosity was increased to about 73% (see panel D of FIG. 7). Next, the dry inos obtained after primary ethanol treatment was dissolved in the powder at about 70% concentration. The supernatant of the solution was dried again to obtain a dry mixture of inos with an increase in the ratio (purity) of D-chiropy Inosine to 70% or more, which was dissolved again in distilled water at a concentration of 10% to 50%. . Secondary ethane was added to this aqueous solution in various amounts to confirm the purification characteristics. This experiment is to confirm the precipitation of ethanol treatment when the purity of D-Cyro-Inosyl is high. The experimental results are shown in FIG. 10. Panels A and B of FIG. 10 show the concentration of myo-inosine in the supernatant when the amount of D-Cyro-inosine is higher than 70% and the amount of ethanol added is 0.5--4 times. The result of having measured the concentration of acro uroinosinolol is shown. The higher the concentration of the inosi, the more precipitated the ethanol was, and the difference in the amount of ethanol added was not different between myo-inosyl and D-chiro-inosirole. Each inos is shown in Panel C and Panel D of FIG. 10 in terms of precipitation rates for the compounds. But it did receive the Maio aspect J is a little precipitate during eu Ino at least about 3-fold amount of ethanol, as the ratio is less than 20% of the actual D- Cairo-effect on the purity of the Inno when appeared to be insignificant.

After treatment with primary ethane, the dry powder of supernatant was dissolved in the amount of completely dissolved water. At this time, the total amount of inos was about 11.5%, and each concentration was 75 g / ml of myo-inos. L and D-Cairo-inosity was 40 g / L. Precipitation and separation were confirmed by adding up to 19-fold ethanol to the mixed solution. The results are shown in FIG. Panel A of FIG. 11 shows the concentration of the supernatant after the addition of ethanol, and in the case of myo-inosity, there was no significant change until about one-fold ethanol was added, but when 1.5 times of ethane was added, More than myo-inos appeared to precipitate. In contrast, D-Cyro-Inosi was found to precipitate slightly in 1.5-fold ethanol, after which the precipitation did not increase significantly. Panel B of FIG. 11 shows the precipitation rate, and in the case of myo-inosine, when about 9 times of ethanol was added, 90% or more of the precipitates were precipitated, and the precipitation rate of D-chiro-inosine was about 20%. appear.

상기 실시예 1 내지 6의 실험결과에서 마이오—이노시를과 D-카이로- 이노시를의 큰 용해도 차이에 의해 에탄올을 이용한 분리가 가능함을 확인하였다. 2개의 탄소를 갖는 에탄올 이외의 다른 유기용매에 의해서도 이러한 분리가 가능한지 확인하기 위해 탄소수 3개의 알코을인 이소프로판올과 케톤인 아세톤을 이용하여 분리를 시도하였다. 마이오ᅳ 이노시틀과 D_카이로 -이노시를의 흔합용액 제조 시, 마이오 -이노시를 및 으 카이로 -이노시를의 비율은 일반적인 반응평형 도달 농도인 약 13 :2로 하였으며ᅳ M9 최소배지 조건으로 전체 농도가 약 15%가 되도록 제조하였다. 제조한 이노시를의 흔합용액에 동일부피의 에탄올, 이소프로판올, 아세톤을 첨가하여 실은에서 1시간 동안 진탕한 후 원심분리하고, 그 상층액을 HPLC로 분석하였다. 결과는 도 12에 나타내었다. 도 12의 패널 A는 실제 상층액에 존재하는 이노시를의 농도를 나타낸 것이다. 마이오 -이노시를의 경우 에탄을과 이소프로판을은 그 농도가 크게 차이나지 않았으나, 아세톤에서는 약간 낮게 나타났다. 으카이로—이노시를의 경우, 이소프로판을에서 에탄을에 비해 농도가 낮았던 반면, 아세톤의 경우에는 유기용매를 처리하지 않았던 농도와 같게 나타나 전혀 침전되지 않은 것으로 나타났다 . 즉, 이소프로판을은 에탄을과 비교할 때 마이오- 이노시를 침전율은 비슷하고, D-카이로 -이노시를의 침전율 (손실율)이 더 높았던 반면, 아세톤은 마이오 -이노시를에 대한 침전율이 더 높고, D- 카이로 -이노시를의 손실율이 적은 것으로 보인다. 이는 에탄을의 침전율에 대한 상대값을 나타낸 도 12의 패널 B에서 쉽게 볼 수 있다. 이소프로판을은 에탄올에 대하여 마이오 -이노시를의 침전율은 동일하고, D- 카이로—이노시를의 침전율은 약 0.7 수준으로 높다. 반면 아세톤의 경우는 마이오 -이노시를의 침전율이 약 0.1배 높으며, D-카이로 -이노시틀에 대해서는 약 1배 수준이 낮은 것으로 나타났다. 따라서 에탄을 이외의 유기용매가 에탄을과 같이 마이오ᅳ이노시롤과 D-카이로 -이노시를의 분리에 사용할 수 있는 것을 확인하였으며, 아세톤의 경우 에탄을에 비해 그 분리 특성이 유리할 수도 있다는 사실을 확인하였다. 본 발명의 실험 결과를 요약하면 다음과 같다. In the experimental results of Examples 1 to 6 it was confirmed that the separation using ethanol due to the large difference in solubility between myo-inosino and D-chiro-inosino. In order to confirm that such separation is possible by an organic solvent other than ethanol having two carbons, separation was attempted using isopropanol having 3 carbon atoms and acetone having ketone. In the preparation of the mixed solution of Myo Ino-Shittle and D_Cairo-Ino City, the ratio of Myo-Ino City and U-Cairo-Ino City was about 13: 2, which is a typical reaction equilibrium concentration. It was prepared such that the total concentration was about 15% under the minimum medium conditions. The same volume of ethanol, isopropanol, and acetone was added to the prepared solution of Inosi, and the mixture was shaken at room temperature for 1 hour, followed by centrifugation. Analyzed by HPLC. The results are shown in FIG. Panel A of FIG. 12 shows the concentration of inosyl in the actual supernatant. The concentrations of ethane and isopropane in myo-inosity were not significantly different, but slightly lower in acetone. In the case of Eucairo-Inosyl, the concentration of isopropane was lower than that of ethane, whereas in the case of acetone, it was the same as the concentration without the organic solvent and did not precipitate at all. That is, isopropane was similar in precipitation rate to myo-inosine and higher in precipitation rate (loss rate) of D-Cairo-inosine, while acetone was higher in precipitation rate for myo-inosine. This is higher, and the loss rate of D-Cairo-Inosi seems to be less. This can be easily seen in panel B of FIG. 12 which shows the relative value for the precipitation rate of ethane. For isopropane, the precipitation rate of myo-inosyl is the same with respect to ethanol, and the precipitation rate of D-chiro-inosyl is as high as about 0.7. On the other hand, in the case of acetone, the precipitation rate of myo-inosyl is about 0.1 times higher, and that of D-Cairo-inositol is about 1 times lower. Therefore, it was confirmed that organic solvents other than ethane can be used to separate myopium inosylol and D-chiro-inosi as ethane, and that acetone may have advantageous separation properties compared to ethane. I confirmed the fact. The experimental results of the present invention are summarized as follows.
