Independent Property

In the search for new carriers capable of transporting toxic drugs to a target, particular attention has been devoted to supramolecular systems with a ribbon-like micellar structure of which Congo red is an example. A special promise of the possible use of such systems for directing drugs to a target emerges from their particular affinity to immune complexes and as an independent property, binding many organic compounds including drugs by intercalation. Serum albumin also appeared able to bind micellar particles of such systems. It may protect them against dilution in transport. The mathematical tool, which relies on analysis of the distribution of polarity and hydrophobicity in protein molecules (fuzzy oil drop model), has been used to find the location of binding area in albumin as well as anchorage site for Congo red in heated IgG light chain used as a model presenting immunoglobulin-like structures. Results confirm the suggested formerly binding site of Congo red in V domain of IgG light chain and indicated the cleft between pseudo-symmetric domains of albumin as the area of attachment for the dye.

H-atom scrambling and cis–trans isomerization of dideuteroethylene have been observed with various photosensitizers: benzene, toluene, p-xylene, o-xylene, m-xylene, mesitylene, fluorobenzene, and benzotrifluoride. The pressure dependences are satisfactorily explained in terms of the two excited state mechanism previously proposed.Using Kassel's equation for the rate of unimolecular reactions, the energies of the triplet states of the sensitizers have been estimated. The values obtained coincide with the spectroscopic values.
