| 外観 | 無色～ほとんど無色透明液体 | | 効能 | 分娩誘発薬, プロスタグランジンF受容体作動薬 | | 商品名 | プロスタルモン (丸石製薬) | | 説明 | Prostaglandin F2α (PGF2α) is present in numerous species and has a widespread distribution. It can cause smooth muscle contraction in the vascular, bronchial, intestinal, and myometrial regions, and has potent luteolytic activity. PGF2α exerts its physiological effects through receptor mediation, with maximal ovine myometrial contraction being achieved at 125 nM PGF2α in vitro, and its receptor-mediated activity is most potent at 50-100 nM. Studies have also shown that PGF2α inhibits nitric oxide production in uterine tissue, enhances uterine contractility, and exhibits potent luteolytic activity. Furthermore, PGF2α functions as an activator of PGF2αR. | | 来歴 | Prostaglandins (PGs) are a class of important endogenous products with a wide range of physiological activities. PGs were first discovered and named by American scholar Von Eluer in 1930. In 1962, Bergstorm extracted two pure PGs (PGF1 and PGF2) and determined their chemical structures. In 1969, Willis first proposed that PGs are an inflammatory mediator in the body. Subsequently, various physiological and pharmacological activities of PGs have been intensively studied. | | 使用 | Prostaglandin F2α is one of the most biologically studied of the primary prostaglandins. Closely related to Prostaglandin E2 (PGE2) in that both prostaglandins are biosynthesized from the same precursors and that PGF2 is the synthetic reduction product of PGE2. | | 定義 | ChEBI: Prostaglandin F2α is a prostaglandins Falpha that is prosta-5,13-dien-1-oic acid substituted by hydroxy groups at positions 9, 11 and 15. It is a naturally occurring prostaglandin used to induce labor. | | 薬物動態学 | Dinoprost is a natural prostaglandin F2α (PGF2α), which can directly act on the myometrium, stimulate the pregnant uterus to contract the uterine muscle, and can soften and dilate the cervix, so it can be used for induced abortion and late labor induction. However, due to the instability of dinoprost at room temperature, inconvenient storage and transportation, complex synthesis process and high cost, the application of dinoprost is difficult to popularize. | | 安全性プロファイル | Poison by subcutaneous, intravenous, and intramuscular routes. Moderately toxic by ingestion. Human and experimental teratogenic and experimental reproductive effects. Human reproductive effects by subcutaneous, intravenous, intramuscular, intraperitoneal, intravaginal, and intraplacental routes: postpartum depression and other maternal effects, abortion, and changes in measures of ferulity. Human teratogenic effects by intraplacental route: extra embryonic structures. Human systemic effects by intravenous route: hypermoulity, diarrhea, nausea or vomiting. Human mutation data reported. When heated to decomposition it emits acrid smoke and fumes | | Mode of action | Prostaglandin F2α (PGF2α) stimulates myometrial activity, relaxes the cervix, inhibits corpus luteal steroidogenesis, and induces luteolysis by direct action on the corpus luteum. In pregnancy, PGF2α is medically used to sustain contracture and provoke myometrial ischemia to accelerate labor and prevent significant blood loss in labor. |
