Abstract

Six new carbocyclic nucleosides were prepared by mounting a purine (compounds 5-7), 8-azapurine (compounds 9 and 10) or pyrimidine (compound 13) base on the amino group of (1R,cis)-3-(aminomethyl)-1,2,2-trimethylcyclopentylmethanol (2). The antiviral activity of compounds 5-7, 10 and 13, and their cytostatic activity, were evaluated. At subtoxic concentrations, the compounds showed no or marginal antiviral activity. Compound 5 showed moderate inhibition on tumor cell proliferation.
