Formation of 3′-O-β-Galactosyl Compounds of 5-Bromouridine by Sporobolomyces singularis

抄録

  Two new compounds of 5-bromouridine, 3′-O-(β-D- galactopyranosyl)-5-bromouridine and 3′-O-[β-D-galactopyranosyl-(1→4)-β-D-galactopyranosyl]-5-bromouridine, were found to be selectively formed in a high yield in a culture filtrate of Sporobolomyces singularis, when grown on a medium containing lactose and 5-bromouridine.
