Table 1. UV Thermal Melting Changes (ΔTm) for Small Compound-Quadruplex Complexes and a Control Duplex Sequencea.

  G4-hTERT, ΔTm(°C)(Tm= 67 °C) G4-HTR, ΔTm(°C)(Tm= 62 °C) Duplex DNA, ΔTm(°C)(Tm= 85 °C)
SOP1812 18 10 2
CM03 13 5 2
MM41 >16b 11 <2
a

The thermal melting results are averages of two independent trials and are reproducible within ±1 °C. Tm values of these sequences without compounds are listed above.

b

Thermal melting changes of MM41with G4-hTERT resulted in a nonstandard melting curve. We therefore predicted the ΔTm value based on the similarity in structures between MM41 and SOP1812.
