  • Improvements to the Synthesis of Isofagomine, Noeuromycin, Azafagomine, and Isofagomine Lactam, and a Synthesis of Azanoeuromycin and 'Guanidine' Isofagomine
    作者:Peter J. Meloncelli、Robert V. Stick
    DOI:10.1071/ch06241
    日期:——

    Improvements in the preparation of a key imidazylate and the reduction of the derived nitrile have led to more efficient syntheses of isofagomine, noeuromycin, azafagomine, and isofagomine lactam. As well, a precursor of azafagomine has been converted into azanoeuromycin, and the nitrogen atom of isofagomine has been incorporated into a guanidine residue.

  • D-Glucosylated Derivatives of Isofagomine and Noeuromycin and Their Potential as Inhibitors of β-Glycoside Hydrolases

    While isofagomine and noeuromycin have previously been demonstrated to be effective inhibitors of a range of exo-acting glycosidases, they are usually only very weak inhibitors of endo-glycosidases. However, the disaccharide-like 3- and 4-O-β-d-glucopyranosylisofagomines have proven to be strong inhibitors of these endo-acting enzymes that utilize multiple sub-sites. In an attempt to emulate these successes, we have prepared 3- and 4-O-β-d-glucopyranosylnoeuromycin, the former by a selective glycosylation (at O2) of benzyl 4-C-cyano-4-deoxy-α-d-arabinoside (also leading to another synthesis of 3-O-β-d-glucopyranosylisofagomine), the latter by a non-selective glycosylation of benzyl 4-O-allyl-β-l-xyloside with subsequent introduction of the required nitrile group (also leading to another synthesis of 4-O-β-d-glucopyranosylisofagomine). 3-O-β-d-Glucopyranosylnoeuromycin was evaluated as an inhibitor of a family 26 lichenase from Clostridium thermocellum, and 4-O-β-d-glucopyranosylnoeuromycin as an inhibitor of both a family 5 endo-glucanase from Bacillus agaradhaerans and a family 10 endo-xylanase from Cellulomonas fimi. We also report X-ray structural investigations of 3- and 4-O-β-d-glucopyranosylnoeuromycin in complex with the family 26 and family 5 β-glycoside hydrolases, respectively. The two d-glucosylated noeuromycins were indeed able to harness the additional binding energy from the sub-sites of their endo-glycoside hydrolase targets, and were thus excellent inhibitors (in the nanomolar range), binding as expected in the –1 and –2 sub-sites of the enzymes.

    虽然异法哥明和新霉素以前已被证明是一系列外作用糖苷酶的有效抑制剂,但它们通常只是内作用糖苷酶的非常弱的抑制剂。然而,3-和 4-O-β-d-吡喃葡萄糖异抗淀粉样二糖已被证明是这些利用多个亚位点的内切酶的强抑制剂。为了效仿这些成功经验,我们制备了 3-和 4-O-β-d-吡喃葡萄糖基诺脲霉素,前者是通过对苄基 4-氰基-4-脱氧-α-d-阿拉伯糖苷进行选择性糖基化(在 O2 处)制备的(也导致了另一种 3-O-β-d-吡喃葡萄糖基异法哥明的合成)、后者是通过对苄基 4-O-烯丙基-β-l-木糖苷进行非选择性糖基化,然后引入所需的腈基(也可导致 4-O-β-d-glucopyranosylisofagomine 的另一种合成)。我们对 3-O-β-d-Glucopyranosylnoeuromycin 和 4-O-β-d-Glucopyranosylnoeuromycin 进行了评估,前者是热细胞梭菌(Clostridium thermocellum)26 族地衣酶的抑制剂,后者是琼脂芽孢杆菌(Bacillus agaradhaerans)5 族内切葡聚糖酶和纤维单胞菌(Cellulomonas fimi)10 族内切木聚糖酶的抑制剂。我们还报告了 3- 和 4-O-β-d-glucopyranosylnoeuromycin 分别与 26 族和 5 族 β-糖苷水解酶复合物的 X 射线结构研究。这两种 d-葡糖基化的新诺霉素确实能够利用其内糖苷水解酶目标亚位点的额外结合能,因此是极好的抑制剂(在纳摩尔范围内),如预期的那样与酶的-1 和-2 亚位点结合。
