title: Synthesis and biological activities of 8-substituted 2-5A analogues.
abstract: The 8-(2-hydroxypropyl)-adenosine and 8-hydroxy adenosine-substituted analogues of 2-5A and it's derivatives were synthesized and their biological activity was evaluated in mouse L cell extracts. The 8-hydroxy adenosine-substituted analogues (i.e. pppAOH2'p5AOH2'p5'AOH, pAOH2'p5'AOH2'p5'AOH, pppA2'p5'A2'p5'AOH, pA2'p5'A2'p5'AOH) inhibited protein synthesis with a relative activity compared to the parent 2-5A. Further, the greater interest is the observation that the corresponding 5'-monophosphate had to inhibitory activity. However, 8-(2-hydroxypropyl)-adenosine substituted analogue (pAHPr2'p5'AHPr2'p5'AHPr) can not about bound as well as parent 2-5A.
