title: Enzymatic synthesis and anti-coagulant effect of salicin analogs by using the Leuconostoc mesenteroides glucansucrase acceptor reaction.
abstract: Glucansucrases from Leuconostoc mesenteroides catalyze the transfer of glucosyl units from sucrose to other carbohydrates by acceptor reaction. We modified salicyl alcohol, phenol and salicin by using various glucansucrases and with sucrose as a donor of glucosyl residues. Salicin, phenyl glucose, isosalicin, isomaltosyl salicyl alcohol, and a homologous series of oligosaccharides, connected to the acceptors and differing from one another by one or more glucose residues, were produced as major reaction products. By using salicin and salicyl alcohol as acceptors, B-1355C2 and B-1299CB-BF563 dextransucrases synthesized most widely diverse products, producing more than 12 and 9 different kinds of saccharides, respectively. With phenol, two acceptor products and oligosaccharides were synthesized by using the B-1299CB-BF563 dextransucrase. Salicyl derivatives, as acceptor products, showed higher anti-coagulation activity compared with that of salicin or salicyl alcohol that were used as acceptors.
