✦ Synopsis

By a mixed condensation of 1,3-bis(3″,4″-dicyanophenoxy)-2-ethyl-2-methylpropane with a large amount of 4,5-bis(3,3-dimethyl-1-butynyl)phthalonitrile, 1,3-bis-2″-(9″,10″,16″,17″,23″,24″-hexakis(3″,3″-dimethyl-1″-butynyl)phthalocyaninoxyl)-2-ethyl-2-methylpropane, was synthesized as a binuclear phthalocyanine having a single isomer. NMR studies at various temperatures and concentrations suggested that the interactions between the phthalocyanine macrocycles were dominated by intermolecular aggregation at lower temperatures or high concentrations whereas intramolecular aggregation was predominant at higher temperatures or lower concentrations.

Covalent linkages such as disulfide bonds are important for the stabilization of proteins. In the present NMR study we compare the structure and the dynamics of the single disulfide-deficient variant C45A/C73A of the ␣-amylase inhibitor tendamistat and the wild-type protein, which contains two disul
