S-GLUCOSYLATED HYDANTOINS AS NEW ANTIVIRAL AGENTS

S-Glycosylation took place on reaction of 5-alkylidene- and 5-aryliden e-3-aryl-2-thiohydantoins with glycosyl halides under alkaline conditi ons. Bisglucosylation also took place when N-3 unsubstituted hydantoin s were reacted. The bisglucosylated hydantoins produced N-3 glucosylat ed hydantoins on treatment with ammonia in methanol. In antiviral stud ies the most active compounds against both HSV-1 and HSV-2 were 5- (2- thienylmethylene) -3-phenyl-2-(2,3 4,6-tetra-O-acetyl-beta-D-glucopyra nosyl) -2-thiohydantoin and 5-(2-thienylmethylene)-3-(4-chlorophenyl) -2- (2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl) -2-thiohydantoin.
