CAS 34837-55-3: Benzeneselenenyl bromide

Phenylselenenyl bromide is a fatty acid with a selenium atom in the side chain. It has an unsymmetrical structure and reacts with thrombin receptor, leading to the activation of protein C. Phenylselenenyl bromide is also converted to a glucuronide conjugate in the liver. This compound can be used as an immunosuppressant and has been shown to have anti-inflammatory effects in animal models of autoimmune diseases. Phenylselenenyl bromide may also inhibit nitric oxide production by reacting with nitro groups.br> Phenylselenenyl bromide contains nitrogen atoms that are asymmetric because they are not paired together. This means that one of the two nitrogen atoms is surrounded by four different substituents, while the other nitrogen atom is only surrounded by three different substituents. The structure of phenylselenenynl bromide makes it difficult

Applications Phenylselenyl Bromide is used as a reagent in the synthesis of the antihyperglycemic agent, (+)-Antroquinonol. Phenylselenyl Bromide is also used in the preparation of 9-epi-Artemisinin (A777505); the chiral isomer of Artemisinin (A777500) which is an antimalarial.
