프로스타글란딘D2

개요Prostaglandin D2 (PGD2) is the major eicosanoid product of mast cells and is released in large quantities during allergic and asthmatic anaphylaxis. Mastocytosis patients produce excessive amounts of PGD2, which causes vasodilation, flushing, hypotension, and syncopal episodes. PGD2 is also produced in the brain via an alternative pathway involving a soluble, secreted PGD-synthase also known as β-trace. In the brain, PGD2 produces normal physiological sleep and lowering of body temperature. Further pharmacological actions include inhibition of platelet aggregation and relaxation of vascular smooth muscle. PGD2 inhibits human ovarian tumor cell proliferation with an IC50 of 6.8 μM.

용도Prostaglandin D2 is a fatty acid compound present in the human body. Elevated levels of localized Prostaglandin D2 has been linked to hair loss and growth inhibition. It has also been seen to contribute to the activity of allergic asthma.
