title: Synthesis and biological evaluation of some 4-substituted 1-[1-(4-hydroxybutyl)-1,2,3-triazol-(4 &5)-ylmethyl]-1H-pyrazolo- 13,4-dipyrimidines.
abstract: The synthesis of 1-[1-(4-hydroxybutyl)-1,2,3-triazol-(4 and 5)-ylmethyl]-1H-pyrazolo[3,4-d]pyrimidines 11a,b, 12a,b and 13-17 as carboacyclic nucleosides is described. The compounds 8a,b were condensed, separately, with compound 7 via 1,3-dipolar cycloaddition reaction to afford, after separation and deprotection. 1,4-regioisomers 11a,b and 1,5-regioisomers 12a,b. The deprotected carboacyclic nucleosides 11a served as precursor for the preparation of 4-amino 13. 4-methylamino 14, 4-benzylamino 15, 4-methoxy 16 and 4-hydroxy 17 analogues. All deprotected carboacyclic nucleosides were evaluated for their inhibitory effects against the replication of HIV-1(III), HIV-2(ROD), various DNA viruses, a variety of tumor-cell lines and tuberculosis. No marked biological activity was found.
