Photochemistry and DNA-affinity of some pyrimidine-substituted styryl-azinium iodides
Photochemical & Photobiological Sciences, 2011The relaxation properties of the excited states of three iodides of trans-1,2-diarylethene analogues (where one aryl group is a methylpyridinium, methylquinolinium or dimethylimidazolium group and the other one is a phenyl ring para-substituted by a pyrimidine ring) have been investigated in buffered (pH = 7) aqueous solution.

Impact of sulfur substitution on biotin binding affinity to streptavidin
Bioorganic ChemistryIn this study, we investigated how the replacement of the tetrahydrothiophene ring of biotin with either an oxolane or (methyl)pyrrolidine moiety may affect its molecular interactions, in an effort to identify alternative affinity ligands suitable for in vitro and in vivo applications in synthetic biology.
