A study of solvent effects on the phosphorescence properties of flavins was written by Brunk, G. R.;Martin, K. A.;Nishimura, A. M.. And the article was included in Biophysical Journal in 1976.SDS of cas: 322-46-3 This article mentions the following:
A combination of zero-field triplet-state techniques was used to study the excited electronic states of a series of flavin and flavin related mols. both in single crystals and glass matrixes. Particular attention was given to the effects of solvent interaction on the triplet-state properties of the flavin mols. The total phosphorescence decay rate constants at 1.4 K are reported for the flavin mols. in polar and nonpolar solvents. The rate constants were correlated to the degree of solvent interaction. Results indicated possible complex formation between the isoalloxazine and adenine groups in FAD. The results and possible interpretation on the flavoenzyme, L-amino acid oxidase, are presented. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3SDS of cas: 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine is an N-heterocyclic moiety, and it can be easily prepared from ethylenediamine and 1,2-diketone, 浼?hydroxyketone, 浼?methyl ketone. Pyrazine-based skeletons were incorporated into agents targeting a range of ailments. Many derivatives were synthesized and evaluated as potential cancer treatments.SDS of cas: 322-46-3
