title: Antiviral compounds. 1. Structure-activity relationship of some antiviral enediones derived from aldehydo sugars.
abstract: A series of aldehydo sugars was subjected to condensation reactions with active methylene compounds. Acetylacetone was condensed with 2,4-O-benzylidene-3,5-O-dibenzoyl-D-ribose (1), 2,4:3,5-O-dibenzylidene-D-ribose (6), 2,3,4,5-tetraacetyl-D-ribose (7), and 2,3,4,5,6-pentaacetyl-D-glucose (9) to yield 3-ylidene-2,4-pentanedione derivatives 2, 11, 12, and 13, respectively. Sugar derivatives 1 and 6 were also condensed with benzoylacetone to give 14 and 18, with acetoacetanilide to give 16 and 19, with malononitrile to give 17 and 20, and with alpha-(gamma-butyrolactonylidene)triphenylphosphorane to give 21 and 22, respectively. Condensation of 1 with dibenzoylmethane gave 15. The double bond in compounds 2 and 11 was saturated by hydrogenation to give 23 and 24. All alpha, beta-unsaturated carbonyl compounds obtained exhibited antiviral activity and cytotoxicity. Compound 11 was found to have the most significant and selective antiviral activity against herpes simplex virus.
