Derivatives Of

The structures of two derivatives of the bisdioxine diisocyanate 1, the bisurea 4 and the biscarbamate 5, are established by X-ray crystallography and DFT calculations. These compounds possess endo,endo structures, in the case of the bisurea 4 with two nearly parallel pendant chains. The X-ray structures are reproduced very well by DFT calculations. Similar endo,endo conformations are calculated for the bisamide crown ether derivatives 7, where two proximate and nearly parallel crown ether units endow the molecules with a claw-like molecular cleft or tweezer structure as evidenced by an enhanced ability to extract some alkali, alkaline earth and rare earth metal ions.

The Difference

The structural transition of DNA double-stranded induced by Ce3+ or Mg2+ ions was investigated in this paper. By atomic force microscopy, different types of condensed DNA structures were observed at the presence of Ce3+ or Mg2+ ions. The results show that there are some differences between rare earth ions and alkaline earth metal ions in the DNA condensation process.
