Synthesis of 2',5'-oligoadenylate analogs possessing a linker moiety in the place of the second adenosine and their ability to activate human RNase L.

ABSTRACT

This paper describes the synthesis of 2',5'-oligoadenylate analogs possessing a linker moiety in the place of the second adenosine and their ability to activate human RNase L. Thus, 2-5A analogs (2a-c & 3a-c) possessing -O(CH(2)CH(2))nO- moieties (n = 1 approximately 3) or aromatic ring moieties were prepared. The EC(50) value of the 2-5A analog (2a) incorporating ethylene glycol showed 700 nM in RNase L activation activity.
