Abstract

The interaction of water-soluble porphyrins with the bovine serum albumin in borate buffer at pH 8.6 has been studied. The localization of porphyrins in the protein globule has been determined. It was established that the native conformation of albumin upon binding with the porphyrins is preserved, however, the anionic porphyrins are exhibit wedging effect on the albumin domains. The binding constants were obtained from fluorescence spectroscopy data.

Abstract

Molecular complex formation of zinc(II)tetraphenylporphyrin with the ligands—diamino compounds in toluene was studied using calorimetric and spectroscopy titration. The structure of the complexes has been confirmed using 1H NMR and fluorescence spectroscopy. Nature of the interaction between the ligand and the solvent was established using TGA of solvates.
