Description
| - The effect of the location of the interstrand cross-link formed by trans-diamminedichloroplatinum(H) (transplatin) on the thermal stability and energetics of 15-mer DNA duplex has been investigated. The duplex containing single, site-specific cross-link, thermodynamically equivalent model structures (hairpins) and nonmodified duplexes were characterized by differential scanning calorimetry, temperature-dependent uv absorption, and circular dichroism. The results demonstrate that the formation of the interstrand cross-link of transplatin does not affect pronouncedly thermodynamic stability of DNA: the cross-link induces no marked changes not only in enthalpy, but also in %22reduced%22 (concentration independent) monomolecular transition entropy. These results are consistent with the previous observations that interstrand cross-links of transplatin structurally perturb DNA only to a relatively small extent.

- Byl studován vliv polohy meziřetězcového můstku vytvořeného trans-dimmindichloroplatnatým komplexem (transplatinou) na tepelnou a termodynamickou stabilitu DNA pomocí diferenční skenovací kalorimetrie. Bylo zjištěno, že poloha můstku v duplexu DNA moduluje kooperativitu procesu tání duplexu a následně také tepelnou stabilitu. (cs)
