3',5'-cyclic pyrimidine nucleoside phosphorothioates
Description:
3',5'-cyclic pyrimidine nucleoside phosphate analogues, where a phosphate oxygen has been exchanged for sulphur generating a chiral phosphorothioate. In 3',5'-cyclic nucleoside phosphorothioate, the oxygen atoms at the 3'- and 5'-positions of the ribose are part of the phosphorothioate group.
