13,14-dihydro-15-keto Prostaglandin E1-d4

13,14-dihydro-15-keto Prostaglandin E1-d4 (13,14-dh-15-k PGE1-d4) is intended for use as an internal standard for the quantification of 13,14-dh-15-k PGE1 by GC- or LC-mass spectrometry. 13,14-dh-15-k PGE1 is a metabolite of PGE1 with much reduced biological activity. Steady state plasma concentrations are about 10 pg/ml. 13,14-dh-15-k PGE1 is a weak inhibitor of ADP-induced platelet aggregation in human PRP and washed platelets with IC50 values of 54 and 200 µM, respectively, compared to PGE1 which has an IC50 value of 40 nM.Formal Name: 9,15-dioxo-11alpha-hydroxy-prostan-1-oic-3,3,4,4-d4 acid.
