Prostaglandin H1 (PGH1) is the unstable precursor to all 1-series PGs and thromboxanes.1,2,3 It is produced from dihomo-γ-linolenic acid (DGLA; Item No. 90230) by COX-1 and COX-2. 4,2 PGH1 is an agonist of the PGD2 receptor CRTH2.5 It increases intracellular calcium levels in HEK293 cells expressing CRTH2 when used at a concentration of 3 µM and induces CRTH2 internalization at 1 µM, an effect that can be blocked by the CRTH2 antagonist TM30089 (CAY10471; Item No. 10006735). PGH1 is also a suicide inhibitor of platelet thromboxane synthase (Ki = 28 µM).6WARNING This product is not for human or veterinary use.
