Product Introduction
Bioactivity


英文名: Procion Blue HB

描述: Procion Blue HB is an antagonist of purinergic.

体外活性: Reactive Blue 2 is used as an ATP receptor antagonist and induces Ca2+ oscillations in HeLa cells. Reactive Blue 2 enhances a Ca2+ response to histamine that is linked to the PLC cascade. Reactive Blue 2 may activate the PLC cascade in an extracellular Ca2+-dependent manner and induce Ca2+ oscillations [1]. The application of Reactive Blue 2 increases K+ secretion in a dose-dependent manner. Reactive Blue 2 has antagonistic activities at P2Y4, and the antagonist potency at P2Y4 paralleled the potency of K+ secretion [2]. The anthraquinone dye reactive blue 2 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 μM 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]. Reactive Blue 2 selectively inhibits responses mediated via the P2ypurinoceptor, at least within a limited concentration range. In preparations where the tone has been raised with ATP, noradrenaline, and 2-methylthio ATP, but not α,β-methylene ATP, produces relaxations of the vessel. These relaxations are inhibited in the presence of reactive blue 2 [4]. Reactive blue 2 (0.3-10 μM) blocks the ATP-induced oscillation in a concentration-dependent manner [5].
