Thermal denaturation studies (Tm values) of chimeric ODN with combination of LNA and MP linkages with complementary DNA or RNA and their half-lives towards induced SVPDE hydrolysis (once the modified nucleoside was reached)177.
| ODN (5′ → 3′)a | T m with DNA (°C) | T m with RNA (°C) | t 1/2 (min) |
|---|---|---|---|
| d(GTGATATGC) | 29 | 27 | <2 |
| d(GTLGATLATLGC) | 44 | 53 | <5 |
| d(GTGMPATAMPTGC) | 27 | 22 | 30 |
| d(GTLGMPATLAMPTLGC) | 39 | 47 | >60 |
L and MP refer to LNA residues and methylphosphonate internucleoside linkages respectively.
