Self-association of violamycin (VBI)

Self-association of violamycin (VBI)

Violamycin (VBI) self-associates in aqueous solution at concentration greater than 7 X 10 −5 M. We report in this paper visible spectrophotometric and kinetic experiments that characterize this self-association. We started from a simple dimerization model supported by our experimental data, and we u...

Zusammenfassung:Violamycin (VBI) self-associates in aqueous solution at concentration greater than 7 X 10 −5 M. We report in this paper visible spectrophotometric and kinetic experiments that characterize this self-association. We started from a simple dimerization model supported by our experimental data, and we used different methods described in literature for the computation of the dimeric extinction coefficient Ed at various wavelengths and the dimerization constant K d = 9300 M −1.
