Background

Prostaglandin D2 (PGD2) is the major eicosanoid product of mast cells and is released in large quantities during allergic and asthmatic anaphylaxis.[1] Mastocytosis patients produce excessive amounts of PGD2, which causes vasodilation, flushing, hypotension, and syncopal episodes.[1] 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.[2],[3] Further pharmacological actions include inhibition of platelet aggregation and relaxation of vascular smooth muscle.[4] PGD2 inhibits human ovarian tumor cell proliferation with an IC50 of 6.8 μM.[5]

前列腺素D2 (PGD2) 是肥大细胞的主要花生四烯酸产物，在过敏性和哮喘性过敏反应期间大量释放。[1] 肥大细胞增生症患者产生过多的 PGD2，引起血管扩张、潮红、低血压和晕厥等症状。[1] PGD2 也通过一种可溶性分泌的 PGD 合成酶 (也称为β-痕迹) 的另一途径在大脑中产生。[2],[3] 在大脑中，PGD2 产生正常的生理性睡眠和降低体温。[2],[3] 进一步的药理作用包括抑制血小板聚集和松弛血管平滑肌。[4] PGD2 对人卵巢肿瘤细胞的增殖具有抑制作用，其 IC50 值为 6.8 μM。[5]
