PGE synthase (Prostaglandin E synthase), which converts cyclooxygenase (COX)-derived prostaglandin H2 (PGH2) to PGE2, is known to comprise a group of at least three structurally and biologically distinct enzymes. There are membrane-associated PGES (mPGES)-1, mPGES-2, and cytosolic PGES (cPGES).

mPGES-1 is a perinuclear protein that is markedly induced by proinflammatory stimuli and downregulated by anti-inflammatory glucocorticoids as in the case of COX-2. It is functionally coupled with COX-2 in marked preference to COX-1. mPGES-2 is synthesized as a Golgi membrane-associated protein, and the proteolytic removal of the N-terminal hydrophobic domain leads to the formation of a mature cytosolic enzyme. This enzyme is rather constitutively expressed in various cells and tissues and is functionally coupled with both COX-1 and COX-2. cPGES is constitutively expressed in a wide variety of cells and is functionally linked to COX-1 to promote immediate PGE2 production.

    Oxidopamine hydrobromide
    		Inducer 99.95%
    Oxidopamine (6-OHDA) hydrobromide is an antagonist of the neurotransmitter dopamine. Oxidopamine hydrobromide is a widely used neurotoxin and selectively destroys dopaminergic neurons. Oxidopamine hydrobromide promotes COX-2 activation, leading to PGE2 synthesis and pro-inflammatory cytokine IL-1β secretion. Oxidopamine hydrobromide can be used for the research of Parkinson’s disease (PD), attention-deficit hyperactivity disorder (ADHD), and Lesch-Nyhan syndrome.
