Abstract

The Suzuki-Miyaura reaction of protected 6-chloropurine and 2-amino-6-chloropurine bases and nucleosides with substituted phenylboronic acids led to the corresponding protected 6-(substituted phenyl)purine derivatives 6-9. Their deprotection yielded a series of substituted 6-phenylpurine bases and nucleosides 10-13. Significant cytostatic activity (IC(50) 0.25-20 micromol/L) in CCRF-CEM, HeLa, and L1210 cell lines was found for several 6-(4-X-substituted phenyl)purine ribonucleosides 12 (X = H, F, Cl, and OR), while the 6-phenylpurine and 2-amino-6-phenylpurine bases 10 and 11, as well as 2-amino-6-phenylpurine ribosides 13, were entirely inactive against these cell lines.
