Homogenates of human breast skin form prostaglandins E(2) and F(2alpha) in the presence of arachidonic acid substrate. Significant inhibition of biosynthesis of prostaglandin E(2) and F(2alpha) was observed in the presence of the anti-inflammatory corticosteroid fluocinolone acetonide. This effect was dose-related. By contrast no significant inhibition was observed in the presence of an approximately equimolar concentration of hydrocortisone.Since prostaglandins have been recovered from several types of inflammatory reactions and are capable of mediating most of the components of inflammation the possibility arises that corticosteroids may owe their anti-inflammatory activity at least in part to inhibition of prostaglandin biosynthesis.
在花生四烯酸底物存在的情况下,人乳房皮肤匀浆会形成前列腺素E(2)和F(2α)。在抗炎皮质类固醇醋酸氟轻松存在时,观察到前列腺素E(2)和F(2α)生物合成受到显著抑制。这种作用与剂量相关。相比之下,在存在近似等摩尔浓度的氢化可的松时,未观察到显著抑制作用。由于已在多种炎症反应中检测到前列腺素,且它们能够介导炎症的大多数成分,因此有可能皮质类固醇的抗炎活性至少部分归因于对前列腺素生物合成的抑制。
