Prostaglandin J2 (PGJ2) is formed from PGD2 by the elimination of the C-9 hydroxyl group, a process which is accelerated by the presence of albumin.1 PGJ2 inhibits platelet aggregation with an IC50 of about 5-10 nM.2,3 PGJ2 has antimitotic and antiproliferative effects on a variety of cultured normal cells and tumor cell lines.4 However, this activity has been attributed to further metabolites of PGJ2 and not the parent compound itself.
