Application

Phthalocyanine tetrasulfonate hydrate has been used as a tau aggregation inhibitor (TAI) to study its effects on Tau secretion in neuroblastoma cells. It has also been used as an anionic phthalocyanine to study its effects on telomere G-quadruplex stabilization.

Biochem/physiol Actions

Inhibitor of protein aggregation, including α-synuclein, and the formation of protease-resistant prion protein.

Fluorescein, and derivatives of fluorescein, are often used as fluorescent probes and sensors. In systems where pH is a variable, protonation/deprotonation of the molecule can influence the pertinent photophysics. Fluorination of the xanthene moiety can alter the molecule's pKa such

The chemiluminescence (CL) signal immediately appeared when a hydrogen peroxide solution was injected into an iron-phthalocyanine tetrasulfonic acid (Fe-PTS) aqueous solution. Moreover, the CL intensity of Fe-PTS decreased by adding l-tyrosine. Based on these results, the determination of trace amounts

Tauopathies are characterized by cerebral accumulation of Tau protein aggregates that appear to spread throughout the brain via a cell-to-cell transmission process that includes secretion and uptake of pathological Tau, followed by templated misfolding of normal Tau in recipient cells.
