    • The present invention relates to a novel phenazine group antibacterial substance having an antibacterial effect against plant pathogens produced by Burkholderia glumae 411gr-6 and, more specifically, to 5, 10-dihydro-4, 9-dihydroxyphencomycin methyl ester represented by chemical formula 1, phencomycin (CAS# 146615-53-4), 4-hydroxyphencomycin, and 4-hydroxyphencomycin methyl ester (CAS# 79417-76-8) represented by chemical formula 3, and to a method for producing the same. The novel phenazine group antibacterial substance is able to inhibit the spore germination and hypha growth of the plant pathogens, including Phythophthora capsici, Colletotrichum orbiculare, Botrytis cinerea, and Magnaporthe oryzae, causing serious financial damage with regards to fruit trees and agricultural products, at low doses, thereby providing a low-toxic and eco-friendly new pest control agent against plant diseases.
    • 本发明涉及一种对由伯克霍尔德氏菌411gr-6产生的植物病原体具有抗菌作用的新型吩嗪基抗菌物质,更具体地说,涉及由化学式1表示的5,10-二氢-4,9-二羟基顺铂霉素甲酯, 苯甲霉素(CAS#146615-53-4),4-羟基辛青霉素和由化学式3表示的4-羟基辛羟霉素甲酯(CAS#79417-76-8)及其制备方法。 新颖的吩嗪类抗菌物质能够抑制植物病原体的孢子萌发和菌丝生长,包括辣椒疫霉(Colphtotrichum orbiculare),灰葡萄孢(Botrytis cinerea)和稻米谷(Magnaporthe oryzae),对果树和农产品造成严重的财务损失 从而为植物疾病提供一种低毒,环保的新型有害生物防治剂。

    • PURPOSE: Provided are the nerve cell protectants produced from Streptomyces sp. and preparation method thereof. In vitro test, their pharmaceutically acceptable organic and inorganic salts, hydrates and isomers show strong inhibition of the cell toxicity and thereby protect the nerve cells. CONSTITUTION: The derivatives isolated from the growth medium of Streptomyces sp. genus 833 (KCTC 8796 P), are represented by the chemical structure 1, 2, 3. These phenazostatin structures are identified by the instrumental analysis. These compounds are separated from the organic solvents extracts of the growth medium through column chromatography and final 3 active fractions are recrystallized from methanol. In screening, N18-RE-105 cell has been used as the vitro model to examine the compounds. In the test, the compounds show inhibitory activity against the active oxygens such as superoxide, hydrogen peroxide and hydroxyl radical. These phenazostatin compounds show strong inhibition activity of L-glutamate cell toxicity of the above model cell.
    • 目的:提供由链霉菌属(Streptomyces sp。)生产的神经细胞保护剂。 及其制备方法。 体外试验中,其药学上可接受的有机和无机盐,水合物和异构体显示出对细胞毒性的强烈抑制,从而保护神经细胞。 构成:从链霉菌属生长培养基中分离得到的衍生物 属833(KCTC 8796 P)由化学结构1,2,3表示。这些吩噻嗪类结构通过仪器分析鉴定。 通过柱层析将这些化合物与生长培养基的有机溶剂提取物分离,最后的3个活性级分用甲醇重结晶。 在筛选中,已经使用N18-RE-105细胞作为体外模型来检查化合物。 在试验中,化合物显示出对超氧化物,过氧化氢和羟​​基自由基等活性氧的抑制活性。 这些吩噻嗪化合物对上述模型细胞的L-谷氨酸盐细胞毒性具有强烈的抑制活性。
