英文摘要 | the interaction thermodynamics of heptacarboxylporphyrin (hcp) and protoporhyrin (pp) with human serum albumin (hsa) was studied by affinity capillary electrophoresis (ace) over the temperature range of 25 - 50 degrees c, where hcp pp bound to hsa via 1:1 molecular association. the binding equilibrium constants (ph 7.4, phosphate buffer) for the binding of hcp with hsa were found to decrease wi ih an increase in temperature, whereas the binding constants of the pp/hsa system appeared to be independent of temperature changes over the range studied. the van't hoff relationship (25 - 50 degrees c) was found to be linear for the interaction of either hcp or pp with hsa. however, the interaction thermodynamics for both of these porphyrins with hsa were found to be quite different. in particular the interaction of hcp (a hydrophilic porphyrin) with hsa appeared to be based on an enthalpy-driven process, whereas the binding between pp (a hydrophobic porphyrin) and hsa driven by a favorable change in entropy. the ability of using ace to evaluate the interaction thermodynamics of serum proteins (e.g, hsa) with ligands (e.g., porphyrins and related compounds) should aid in the development of new and more effective photosensitizers in the photodynamic therapy of cancer. |
