Synthesis and anticancer activity of 4-amino-5-oxo-8-(beta-D-xylofuranosyl)pyrido[2,3-d]pyrimidine.

4-Amino-5-oxo-8-(beta-D-xylofuranosyl)pyrido[2,3-d]pyrimidine (4) was recently synthesized and evaluated in our laboratories for anticancer activities. This compound showed potent in vitro inhibitory effects on the growth of HTB-81 prostate cancer cells and Daudi-lymphoma. In vivo studies showed that the compound could inhibit HTB-81 tumor growth in syngeneic mice by 93% at a daily dose of 8.5 mg/kg for 10 days.
