Forskolin is a diterpene that activates adenylate cyclase in a variety of mammalian cells. In addition of forskolin to blowfly salivary glands increased cyclic AMP accumulation and salivary secretion. There was a small increase in transepithelial movement of labelled Ca2+. Forskolin did not induce breakdown of labelled phosphatidylinositol or inhibit the stimulation of phosphatidylinositol breakdown caused by 5-hydroxytryptamine. These data indicate that forskolin can mimic all the effects of 5-hydroxytryptamine on salivary-gland secretion that have been attributed to cyclic AMP.
福斯高林是一种二萜类化合物,可激活多种哺乳动物细胞中的腺苷酸环化酶。将福斯高林添加到丽蝇唾液腺中可增加环磷酸腺苷(cAMP)的积累和唾液分泌。标记的钙离子(Ca2+)的跨上皮运动略有增加。福斯高林不会诱导标记的磷脂酰肌醇分解,也不会抑制5-羟色胺引起的磷脂酰肌醇分解刺激。这些数据表明,福斯高林可以模拟5-羟色胺对唾液腺分泌的所有归因于环磷酸腺苷的作用。
