title: Inhibition of protein synthesis by the cordycepin analog of (2'-5')ppp(Ap)nA, (2'-5')ppp(3'dAp)n3'dA, in intact mammalian cells.
abstract: The introduction of the cordycepin analog of (2'-5')An, (2'-5')ppp(3'dAp)n3'dA [referred to as (2'-5')p33'dAn], into mouse L929 cells and cultured human fibroblasts resulted in a dose-dependent inhibition of protein synthesis which was comparable to the inhibition observed by (2'-5')ppp(Ap)nA [referred to as (2'-5')p3An]. The inhibition of protein synthesis by (2'-5')p33'dAn was much more persistent than that of the naturally occurring (2'-5')p3An following prolonged incubation of cells. Furthermore, the (2'-5')p3An was cytotoxic to mammalian cells in culture, whereas the (2'-5')p33'dAn was not.
