See our recent study about the interactions of ESIPT fluorescent lipophile-based benzazoles with bovine serum albumin (BSA) where their binding affinity was evaluated. The spectral quenching of BSA indicated that these compounds could bind to BSA through a strong binding affinity afforded by a static quenching mechanism. Molecules, 2021, 26(21), 6728. #bsa #ESIPT #benzazoles #fluorescence
