  Enasidenib glycosides and methods of making enasidenib glycosides are disclosed. Glycosyl transferases catalyze addition of one or more monosaccharides to enasidenib to yield enasidenib glycosides. Suitable monosaccharides can be in the L- or D- configuration and typically have 5, 6, or 7 carbons. Suitable monosaccharides include allose, apiose, arabinose, fructose, fucitol, fucose, galactose, galacturonate, glucose, glucuronic acid, mannose, N-acetylglucosamine, rhamnose, or xylose. Uridine diphosphate glycosyl transferases can catalyze formation of either an alpha or beta glycosidic bond.

  本文介绍了Enasidenib糖苷及其制备方法。糖基转移酶催化将一个或多个单糖添加到Enasidenib中，形成Enasidenib糖苷。适宜的单糖可以是L-或D-构型，并且通常具有5、6或7个碳。适宜的单糖包括阿洛糖、芹糖、阿拉伯糖、果糖、甘露醇、岩藻糖、半乳糖、半乳糖醛酸酯、葡萄糖、葡萄糖醛酸、甘露糖、N-乙酰葡萄糖胺、鼠李糖或木糖。尿苷二磷酸糖基转移酶可以催化α或β糖苷键的形成。

  The present invention aims to provide a method for producing a polysaccharide with high efficiency using a polysaccharide synthase. The present invention provides a method for producing a polysaccharide, including allowing polysaccharide synthase (B) to act on ribonucleoside diphosphate-monosaccharide (A) shown below to produce a polysaccharide, wherein in 10 to 100% of the duration in which (B) acts on (A), the concentration of ribonucleoside diphosphate in a reaction solution is lower than 100 times an inhibitory concentration IC50 described below against polysaccharide synthase (B). Inhibitory concentration IC50: a concentration of ribonucleoside diphosphate at which an enzyme activity of polysaccharide synthase (B) is reduced by half while under a condition where (B) has a concentration at which (B) acts on ribonucleoside diphosphate-monosaccharide (A), wherein ribonucleoside diphosphate-monosaccharide (A) is used as a substrate and ribonucleoside diphosphate is used as an inhibitor. Ribonucleoside diphosphate-monosaccharide (A): a sugar nucleotide in which a proton of at least one hydroxyl group of at least one monosaccharide (a) selected from the group consisting of triose (a-1), tetrose (a-2), pentose (a-3), hexose (a-4), heptose (a-5), and monosaccharide (a-6) described below is substituted with a functional group represented by any one of chemical formulae (1) to (5) below. Monosaccharide (a-6) : a monosaccharide selected from the group consisting of (a-1), (a-2), (a-3), (a-4), and (a-5), in which at least one member selected from the group consisting of a proton, a hydroxyl group, and a hydroxymethyl group of the monosaccharide is substituted with substituent (E) described below. Substituent (E) is at least one substituent selected from the group consisting of carboxyl, amino, N-acetylamino, sulfate, methylester, N-glycolyl, methyl, 1,2,3-trihydroxypropyl, phosphate, and 2-carboxy-2-hydroxyethyl groups.

  本发明旨在提供一种利用多糖合成酶高效生产多糖的方法。本发明提供了一种生产多糖的方法，包括让多糖合成酶（B）作用于下图所示的核糖核苷二磷酸-单糖（A）以生产多糖，其中在（B）作用于（A）的10至100%的持续时间内，反应溶液中核糖核苷二磷酸的浓度低于下述对多糖合成酶（B）的抑制浓度IC50的100倍。 抑制浓度 IC50：在(B)对核糖核苷二磷酸单糖(A)起作用的浓度条件下，多糖合成酶(B)的酶活性降低一半的核糖核苷二磷酸浓度，其中核糖核苷二磷酸单糖(A)用作底物，核糖核苷二磷酸用作抑制剂。 核糖核苷二磷酸-单糖 (A)：一种糖核苷酸，其中至少一种单糖 (a) 的至少一个羟基的质子被下述化学式 (1) 至 (5) 中任一个所代表的官能团取代，该单糖选自三糖 (a-1)、四糖 (a-2)、戊糖 (a-3)、己糖 (a-4)、庚糖 (a-5) 和下述单糖 (a-6)。 单糖(a-6)：选自(a-1)、(a-2)、(a-3)、(a-4)和(a-5)组成的组的单糖，其中至少一个选自质子、羟基和羟甲基组成的组的成员被下述取代基(E)取代。 取代基(E)是选自羧基、氨基、N-乙酰氨基、硫酸基、甲基酯、N-甘氨酰、甲基、1,2,3-三羟基丙基、磷酸基和 2-羧基-2-羟乙基组成的组中的至少一个取代基。
