In this work, the interaction between chelerythrine (CHE) and guanosine is studied using UV-vis and fluorescence measurements at various temperatures. The UV-vis spectra show that the increasing guanosine concentrations result in the decreasing absorption intensity and red shift of CHE E absorption band (267 nm). The fluorescence spectra are fitted to linear analysis, yielding a binding constant of 1.04×104 L/mol at 298.15 K of CHE with guanosine. Besides, with △rHΘm =-8.26 kJ/mol, △rGmΘ = -22.90 kJ/mol,and △rSmΘ = 49.38 J/(mol K) the interaction should be entropy-driven and exterothermic.
