In the present work we studied the interactions of a newly synthesized drug candidate, 2-(2-hydroxy-4-methoxybenzylidene)-1-(1H-benzimidazol-2-yl)hydrazine (2H4MBBH), with human serum albumin (HSA) by fluorescence spectroscopy. 2H4MBBH-HSA binding pa

The photosynthetic light-harvesting systems of purple bacteria and plants both utilize specific carotenoids as quenchers of the harmful (bacterio)chlorophyll triplet states via triplet-triplet energy transfer. Here, we explore how the binding of caro
