Biological Activity
Procion Blue HB is used as an ATP receptor antagonist and induces Ca2+ oscillations in HeLa cells. Procion Blue HB enhances a Ca2+ response to histamine that is linked to the PLC cascade. Procion Blue HB may activate the PLC cascade in an extracellular Ca2+-dependent manner and induce Ca2+ oscillations[1].
The application of Procion Blue HB increases K+ secretion in a dose-dependent manner, and this increase is characterized as a peak followed by a partial relaxation to a steady-state. Procion Blue HB has antagonistic activities at P2Y4, and the antagonist potency at P2Y4 paralleled the potency of K+ secretion[2].
The anthraquinone dye Procion Blue HB is found to be a potent inhibitor of a protein kinase isolated and purified from thylakoids. The mode of inhibition is noncompetitive, with a Ki of 8 μM for the membrane-bound kinase, and 6 microM for the purified kinase. The inhibitor does not modify the substrate preference of the endogenous kinase and could be removed from the membrane by washing[3].
Procion Blue HB selectively inhibits responses mediated via the P2ypurinoceptor, at least within a limited concentration range. In preparations where the tone has been raised with noradrenaline, ATP and 2-methylthio ATP, but not α,β-methylene ATP, produce relaxations of the vessel. These relaxations are inhibited in the presence of Procion Blue HB[4].
Procion Blue HB, at concentrations of 0.3-10 μM blocks the ATP-induced oscillation in a concentration-dependent manner[5].
