Description

Prostaglandin D2-d4 (PGD2-d4) contains four deuterium atoms at the 3, 3', 4, and 4' positions. It is intended for use as an internal standard for the quantification of PGD2 by GC- or LC-mass spectrometry. 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.2,3 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.

FAQs

It appears that there is a heterogenous mixture of deuterated species in your deuterated standards; is this normal?

Yes, this is typical of our deuterated products. Our deuterated products contain less than 1 % d0. However, the labeled compounds are not 100% of the deuterated form listed on our product insert. For example, upon analysis of 2-arachidonoyl glycerol-d8 it is expected to see masses associated with the d7, d6, d5 etc.
