Coformational Switch of Oligonucleotide Induced by Spermine [PDF]
Conformational change of nucleic acids induced by a small molecule is essential for many biological reactions and useful for biotechnology. To construct a spermine-responsive nucleic acid, we designed DNA sequences which can potentially form a unimolecular hairpin loop structure and a bimolecular duplex by itself.

Differences in Coformer Interactions of the 2,4-Diaminopyrimidines Pyrimethamine and Trimethoprim
The identification and study of supramolecular synthons is a fundamental task in the design of pharmaceutical cocrystals. The malaria drug pyrimethamine (pyr) and the antibiotic trimethoprim (tmp) are both 2,4-diaminopyrimidine derivatives, providing the same C–NH2/N═C/C–NH2 and C–NH2/N═C interaction sites.
