  Profiling of Glycosidase Activities Using Coumarin-Conjugated Glycoside Cocktails

  摘要：

  Glycosidases are a large subgroup of carbohydrate-processing enzymes that hydrolytically cleave the glycosidic bond. Glycans formed by the action of glycosidases are involved in various biological processes. Genetic abnormalities in glycosidases are associated with inherited diseases. Thus, characterization of the catalytic activities of glycosidases is of great importance. Herein, we describe a simple and rapid approach for determining glycosidase activity profiles using coumarin-conjugated glycoside cocktails.

  An improved Helferich method is presented. It involves the glycosylation of 4-methyl-umbelliferone with glycosyl acetates in the presence of boron trifluoride etherate combined with triethylamine, pyridine, or 4-dimethylaminopyridine under mild conditions, followed by deprotection to give fluorogenic 4-methylumbelliferyl glycoside substrates. Due to the use of base, the glycosylation reaction proceeds more easily, is uncommonly α- or β-stereoselective, and affords the corresponding products in moderate to excellent yields (51%–94%) under appropriate conditions.

  提出了一种改进的Helferich方法，涉及在温和条件下，将4-甲基伞形酮与糖基乙酸酯在三氟化硼乙醷存在下与三乙胺、吡啶或4-二甲氨基吡啶联合使用进行糖基化，随后脱保护得到荧光4-甲基伞形酰基糖苷底物。由于使用碱基，糖基化反应更容易进行，具有不寻常的α或β立体选择性，并在适当条件下获得中等至优异的产率（51%至94%）。

  inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). These coumarins were very weak or ineffective as inhibitors of the housekeeping, offtarget isoforms CA I and II, but some of them inhibited tumor-associated CA IX and XII in the low nanomolar range. They also significantly inhibited the growth of primary tumors by the highly aggressive 4T1 syngeneic mouse mammary tumor cells at 30 mg/kg, constituting

  合成了一系列结合了各种糖基部分的7-取代香豆素，并研究了其对锌酶碳酸酐酶的抑制作用（CA，EC 4.2.1.1）。这些香豆素作为管家抑制剂，脱靶亚型CA I和II非常弱或无效，但其中一些在低纳摩尔范围内抑制与肿瘤相关的CA IX和XII。它们还以30 mg / kg的高侵袭性4T1同系小鼠乳腺肿瘤细胞显着抑制了原发性肿瘤的生长，构成了开发概念上新颖的抗癌药物的有趣候选物。由于CA IX在低氧性肿瘤中过表达，并且在正常组织中的表达非常有限，因此此类化合物可用于治疗对经典化学疗法和放射疗法无反应的癌症。

  Compositions for the treatment of cancer comprising coumarin and thiocoumarin derivatives of Formulas I- XII are disclosed. Said derivatives preferentially inhibit carbonic anhydrase IX and XII (which are associated with hypoxic and metastatic tumours) over inhibiting carbonic anhydrase I and II activity. The compositions therefore are suited for treatment of hypoxic or metastatic cancers due to this selective mechanism of action.
