Background:

Pseudothymidine is a C-nucleoside analog of thymidine.

Pseudothymidine is a C-nucleoside analog of thymidine[1]. The calculated δδG°50/mod is -0.5 kcal/mol, with a δTm/mod of 0.82°C. For the duplexes containing nine dA-T/ψT pairs, the δTm/mod is -0.9°C and a δδG°50/mod is +1.1 kcal/mol. The modification of the duplex containing 12 consecutive dA-T/ψT base pairs produces a δTm/mod of -0.9°C and a δδG°50/mod of +1.2 kcal/mol[2].
