A seriesof twenty four acyclic unsaturated 2,6-substututed purines 5a-20b were synthesized. These compounds were evaluated for cytotoxic activity against NCI-60 DTP human tumor cell line screen at 10?Mconcentration. N 9-[(Z)-4′-chloro-2′-butenyl-1′-yl]-2, 6-dichloropurine(5a), N9-[4′-chloro-2′-butynyl-1′- yl]-2,6-dichloropurine(10a), N9-[(E)-2′,3′-dibromo- 4′-chloro-2′-butenyl-1′-yl]-6-methoxypurine(14)and N 9-[4′-chloro-2′-butynyl-1′-yl]-6-(4-methoxyphenyl) -purine(19)exhibited highly potent cytotoxic activity with GI50 values in the 1-5 μM range for most human tumor cell lines. Other compounds exhibited moderate activity.
Cytostatic 6-arylpurine nucleosides II. Synthesis of sugar-modified derivatives: 9-(2-deoxy-β-D-erythro-pentofuranosyl)-, 9-(5-deoxy-β-D-ribofuranosyl)- and 9-(2,3-dihydroxypropyl)-6-phenylpurines

9-(2-Deoxy-β-D-erythro-pentofuranosyl)-6-(4-substituted phenyl)purines, 9-(5-deoxy-β-D-ribofuranosyl)-6-(4-substituted phenyl)purines and 9-(2,3-dihydroxypropyl)-6-(4-substituted phenyl)purines were prepared by the Suzuki-Miyaura cross-coupling reactions of the corresponding protected 9-substituted 6-chloropurines with substituted phenylboronic acids followed by MeONa mediated deprotection. In contrast to the highly active 6-phenylpurine ribonucleosides, the title compounds did not show any considerable cytostatic activity.
