    • PURPOSE: A manufacturing method of oxiracetam is provided, thereby manufacturing oxiracetam at room temperature under mild condition in higher yield. CONSTITUTION: A manufacturing method of oxiracetam comprises the steps of: condensation of vinyl acetyl chloride of the formula 1 with glycine ethyl ester to prepare 3-butenoylamino-acetic ethyl ester of the formula 2: epoxylation of 3-butenoylamino-acetic ethyl ester of the formula 2 using HO-X in which X is halogen or CH2Cl2 to prepare an epoxy compound of the formula 3 as an intermediate; adding a base to the epoxy compound of the formula 3 for cyclization of the epoxy compound to form 5-membered ring of the formula 4; and dissolving the 5-membered ring of the formula 4 in ammonia water to prepare oxiracetam of the formula 5.
    • 目的:提供一种奥拉西坦的制造方法,由此在室温下在温和条件下以较高的收率制造奥拉西坦。 构成:奥拉西坦的制造方法包括以下步骤:将式1的乙烯基乙酰氯与甘氨酸乙酯缩合制备式2的3-丁烯酰氨基 - 乙酸乙酯:将式2的3-丁烯酰氨基 - 乙酸乙酯环氧化 使用其中X是卤素或CH 2 Cl 2的HO-X来制备式3的环氧化合物作为中间体; 向式3的环氧化合物中加入碱以使环氧化合物环化形成式4的5元环; 并将式4的5元环溶于氨水中以制备式5的奥拉西坦。

    • PURPOSE: A bacteriocin produced by Bacillus polyfermenticus showing direct antibacterial action against Helicobacter Pylori as a causative agent of gastritis is provided. Therefore, it can be used in the treatment of acid peptic disease such as gastritis and duodenal ulcers by oral administration. CONSTITUTION: A bacteriocin as an antimicrobial substance produced by Bacillus polyfermenticus controls or eradicates Helicobacter pylori. For an example, Bacillus polyfermenticus is cultured in a TBS(Difco laboratories) medium, Helicobacter pylori(KCTC 2948) is cultured in a Mueller hinton medium added with 10% bovine calf serum at 37deg.C under anaerobic conditions. Helicobacter pylori in the amount of 10¬6 cfu/ml is smeared to a solid medium and cultured, Bacillus polyfermenticus(10 microliter) remaining in a logarithmic growth phase is spotted and cultured. In the test, the inhibiting effect on the growth of Helicobacter pylori is distinctly observed.
    • 目的:提供由芽孢杆菌(polyfermenticus)产生的细菌素,其显示对幽门螺杆菌作为胃炎致病因子的直接抗菌作用。 因此,可以通过口服治疗酸性消化性疾病如胃炎和十二指肠溃疡。 构成:作为抗菌物质的细菌素,由芽孢杆菌多毛属发酵菌控制或根除幽门螺杆菌。 例如,在TBS(Difco实验室)培养基中培养芽孢杆菌,在37℃,在厌氧条件下,在加入10%牛血清的Mueller hinton培养基中培养幽门螺杆菌(KCTC 2948)。 将10〜6cfu / ml的幽门螺旋杆菌涂抹于固体培养基中并培养,保留在对数生长期的培养物(10微升)的芽孢杆菌。 在试验中,幽门螺杆菌生长抑制作用明显。
