title: Comparison of 2'-fluoro-arabinosyl pyrimidine nucleosides and 1-beta-D-arabinofuranosylcytosine on immunological parameters in vitro.
abstract: 1-beta-D-arabinofuranosylcytosine (ara C)3, 2'-fluoro-5-iodo-arabinofuranosyl-cytosine (FIAC) and 2'-fluoro-5-methyl-arabinofuranosyluracil (FMAU) were analyzed for immunosuppressive activity in vitro. In assay systems quantifying both humoral and cellular immune reactivity, FMAU and FIAC were less immunosuppressive than ara C by several orders of magnitude.
