Kinetic spectrophotometric study of effect of triazolopyrazines on p-benzoquinone complexes.
The effect of adding triazolopyrazines to a p-benzoquinone-proline system and a p-benzoquinone-histamine system was studied by observing the kinetics of the spectral changes and analyzing the results using digital simulation methods. Below 35 degrees, the major effect was that the triazolopyrazine competed with the electron donors for the acceptors to form complexes. Above 35 degrees, there was predominantly a chemical interaction between the triazolopyrazine and the acceptors. A separate experiment showed that the triazolopyrazine interacted with p-benzoquinone to form a complex initially but that a chemical interaction took place later.
