  Inhibition of N-acetylglucosaminyl transfer enzymes: chemical-enzymic synthesis of new five-membered acetamido azasugars

  摘要：

  Two new acetamido azasugars have been synthesized and tested as inhibitors of beta-N-acetylglucosaminase. Ozonolysis of enantiomerically pure N-(4-phenyl-2-azido-3-butenyl)acetamide, derived from cinnamic aldehyde, followed by lipase-catalyzed resolution of the amine intermediate 5, gave 2-azido-3-acetamidopropanal which was then condensed with dihydroxyacetone phosphate by using FDP-aldolase. The condensed product was dephosphorylated and hydrogenated to afford the five-membered acetamido azasugar analogous to N-acetylglucosamine. Compounds 1 and 2 prepared in this manner were new competitive inhibitors of a beta-N-acetylglucosaminidase with K(i) values of 1.9 and 3.6 muM, respectively, and could be useful for the synthesis of N-acetylglucosaminyltransferase inhibitors.

  A one-pot chemoenzymatic method for the synthesis of a variety of new iminocyclitols from readily available, non-phosphorylated donor substrates has been developed. The method utilizes the recently discovered fructose-6-phosphate aldolase (FSA), which is functionally distinct from known aldolases in its tolerance of different donor substrates as well as acceptor substrates. Kinetic studies were performed with dihydroxyacetone (DHA), the presumed endogenous substrate for FSA, as well as hydroxy acetone (HA) and 1-hydroxy-2-butanone (HB) as donor substrates, in each case using glyceraidehyde-3-phosphate as acceptor substrate. Remarkably, FSA used the three donor substrates with equal efficiency, with k(cat)/K-M-values of 33, 75, and 20 M-1 s(-1), respectively. This level of donor substrate tolerance is unprecedented for an aldolase. Furthermore, DHA, HA, and HB were accepted as donors in FSA-catalyzed aldol reactions with a variety of azido- and Cbz-amino aldehyde acceptors. The broad substrate tolerance of FSA and the ability to circumvent the need for phosphorylated substrates allowed for one-pot synthesis of a number of known and novel iminocyclitols in good yields, and in a very concise fashion. New iminocyclitols were assayed as inhibitors against a panel of glycosidases. Compounds 15 and 16 were specific alpha-mannosidase inhibitors, and 24 and 26 were potent and selective inhibitors of beta-N-acetylglucosaminidases in the submicromolar range. Facile access to these compounds makes them attractive core structures for further inhibitor optimization.
