Herg Activator (NS1643, 1,3-bis-(2-hydroxy-5-trifluoromethyl-phenyl)-urea, Human ether-a-go-go related gene (hERG) K+ channel activator, KV11.1 Channel Activator)
A diphenolurea compound that selectively activates human ether-a-go-go-related gene (hERG) K+-channel (EC50=10.5uM). Shown to significantly increase both steady-state and peak tail currents of hERG channels, but exhibits only a trivial effect on Kv4.3 and Kv1.5 channels. Causes a significant reduction in action potential duration (APD90) in patch clamp assays in Xenopus oocytes, HEK293 cells, and guinea pig cardiamyocyes that can be reversed by the addition of E-4031, a specific blocker of hERG channels. Also shown to activate IKr channel in cardiomyocytes and increase post-repolarization refractory time thereby alleviating hyper-excitability and producing antiarrhythmic effects. It can also restore IKr reduced by down-regulation of IKr expression. Group: Biochemicals. Grades: Highly Purified. CAS No. 448895-37-2. Pack Sizes: 10mg.

Native Mushrooms Polyphenol Oxidase
Polyphenol oxidase is a tetramer that contains four atoms of copper per molecule, and binding sites for two aromatic compounds and oxygen. The enzyme catalyses the o-hydroxylation of monophenol molecules in which the benzene ring contains a single hydroxyl substituent) to o-diphenols (phenol molecules containing two hydroxyl substituents). It can also further catalyse the oxidation of o-diphenols to produce o-quinones. PPO causes the rapid polymerization of o-quinones to produce black, brown or red pigments (polyphenols) that cause fruit browning. The amino acid tyrosine contains a single phenolic ring that may be oxidised by the action of PPOs to form o-quinone. Hence, PPOs may also be referred to as tyrosinases. Polyphenol oxidase (tyrosinase) is a bifunctional, copper-containing oxidase having catecholase and cresolase activity. a lyophilized powder. store at -20°c. Group: Enzymes.

tyrosinase
A type III copper protein found in a broad variety of bacteria, fungi, plants, insects, crustaceans, and mammals, which is involved in the synthesis of betalains and melanin. The enzyme, which is activated upon binding molecular oxygen, can catalyse both a monophenolase reaction cycle (reaction 1) or a diphenolase reaction cycle (reaction 2). During the monophenolase cycle, one of the bound oxygen atoms is transferred to a monophenol (such as L-tyrosine), generating an o-diphenol intermediate, which is subsequently oxidized to an o-quinone and released, along with a water molecule. The enzyme remains in an inactive deoxy state, and is restored to the active oxy state by the binding of a...oxidase; cresolase; monophenolase; tyrosine-dopa oxidase; monophenol monooxidase; monophenol dihydroxyphenylalanine:oxygen oxidoreductase; N-acetyl-6-hydroxytryptophan oxidase; monophenol, dihydroxy-L-phenylalanine oxygen oxidoreductase; o-diphenol:O2 oxidoreductase; phenol oxidase.
