• Regioselective Metalation of 6-Methylpurines: Synthesis of Fluoromethyl Purines and Related Nucleosides for Suicide Gene Therapy of Cancer

  Metalation of 6-methyl-9-(tetrahydro-2H-pyran-2-yl)purine (10) with lithiating agents of varying basicities such as n-BuLi and LiHMDS in THF at - 78 degrees C resulted in metalation at both of the 6-CH3 moiety and the 8-CH position, irrespective of the molar equivalence of the base. On the other hand, a regioselective metalation at the 6-CH3 moiety of 10 was observed with NaHMDS or KHMDS, under similar conditions. Treatment of the potassium salts of 10 and of the protected riboside derivative 6-methyl-9-(beta-D-2,3,5-tri-O-tert-butyldimethylsilylribofuranosyl)purine (22) with N-fluorobenzenesulfonamide (NFSI) at - 78 degrees C gave the corresponding 6-fluoromethylpurine derivatives 11 and 23, respectively, in good yields. Deprotection of 11 and 23 under standard conditions gave 6-fluoromethylpurine (6-FMeP, 3) and 6-fluoromethyl-9-(beta-D-ribofuranosyl)purine (6-FMePR, 4), respectively, in high yield. Both 3 and 4 demonstrated cytotoxic activity against CCRF-CEM cells in culture. 6-FMePR is a good substrate for E. coli purine nucleoside phosphorylase (E. coli PNP) with a comparable substrate activity to that of the parent nucleoside, 6-methyl-9-(beta-D-ribofuranosyl)purine (&MePA 21). The cytotoxic activity of 6-FMeP along with the substrate activity of 6-FMePR with E. coli PNP meet the fundamental requirements for using 6-FMeP as a Potential toxin in PAT/prodrug based cancer gene therapy.

  A selective metalation at the 6-CH3 over C-8 of 6-methylpurine derivative 6 was observed with softer counter cation (Na+ or K+) of the base, while the harder Li+ showed no selectivity. In the presence of N-fluorobenzenesulfonamide (NFSI), this property was utilized for the synthesis of 6-fluoromethylpurine derivatives 4 and 5 as potential toxins for suicide gene therapy.

  Two alternative approaches to the synthesis of novel 6-(fluoromethyl)purine bases and nucleosides are described either by direct deoxyfluorination or by multistep functional group transformations starting from 6-(hydroxymethyl)purines. 6-(Fluoromethyl)purine ribonucleoside displayed significant cytostatic effects.
