Novel 6,7-bisaryl-1-(beta-D-ribofuranosyl)pteridine-2,4( 1H,3H)-dione derivatives were synthesized by condensation of 5,6-diamino-2',3'-O-isopropylideneuridine, which was derived from uridine, with an appropriate alpha,beta-diketon, followed by acidic hydrolysis allowing removal of the isopropylidene group of the sugar moiety as a protecting group. Moreover, several N-3 alkyl derivatives of the 6,7-bisaryl-1-(beta-D-ribofuranosyl)pteridine-2,4(1H,3H)-diones were obtained by alkylation of the 6,7-bisaryl-l-(2',3'-O-isopropylidene-beta-D-ribofuranosyl)pteridine-2,4(1H,3H)-diones with alkyl halides and by their acidic hydrolysis for deprotection. The antitumor activities of all synthesized compounds against CCRF-HSB-2 and KB cell lines were also investigated in vitro and some of the compounds showed prospective antitumor activities.
