title: Synthesis and in vitro cytostatic activity of new beta-D-arabino furan[1',2':4,5]oxazolo- and arabino-pyrimidinone derivatives.
abstract: A series of nucleoside derivatives was obtained via heteroatom annulation of the amino oxazoline of D-(-)-arabinose. Unequivocal proofs for the stereostructure of some new arabinosyl pyrimidinone derivatives were obtained by X-ray structure analysis. These newly synthesized compounds were then evaluated for their cytostatic activity against murine leukemia (L1210), and human T-lymphocytes (Molt 4/C8 and CEM). Of all the compounds in the series, the protected silylated tricyclic fused pyrimidinone 10 showed the most significant antitumor activity against murine leukemia L1210 (IC(50)=6 microM), and human T-lymphocytes cells Molt 4/C8 (IC(50)=7.9 microM) and CEM/0 cell lines (IC(50)=7.5 microM). None of the compounds exhibited significant antiviral inhibitory activities.
