SYNTHESIS AND BIOLOGICAL ACTIVITY OF 2-FLUORO ADENINE AND 6-METHYL PURINE NUCLEOSIDE ANALOGS AS PRODRUGS FOR SUICIDE GENE THERAPY OF CANCER |
| |
Abstract: | A novel series of 6-methylpurine nucleoside derivatives with substitutions at 5′-position have been synthesised. These compounds bear a 5′-heterocycle such as triazole or a imidazole with a two carbon chain, and an ether, thio ether or amine. To extend the SAR study of 2-fluoroadenine and 6-methyl purine nucleosides, their corresponding α–linker nucleosides with l-xylose and l-lyxose were also synthesized. All of these compounds have been evaluated for their substrate activity with E. coli PNP. |
