Abstract

The diterpene, forskolin, is shown to produce a concentration-dependent, increase in short circuit current in two epithelial preparations, amphibian skin and rat colon. In the amphibian tissue the increase is sensitive to amiloride and due to an increase in electrogenic transepithelial sodium transport towards the serosal side. In the rat colon piretanide attenuated the forskolin effect, suggesting the terpene increases electrogenic transepithelial chloride transport towards the mucosal side. Half-maximal activation of both processes was achieved with concentration of 1-3 microM, similar to those required to activate half-maximally the catalytic subunit of adenylate cyclase.

摘要

二萜类化合物毛喉素在两种上皮组织——两栖类皮肤和大鼠结肠中,呈现出浓度依赖性地增加短路电流的现象。在两栖类组织中,这种增加对氨氯吡脒敏感,且是由于向浆膜侧的电生性跨上皮钠转运增加所致。在大鼠结肠中,吡咯他尼减弱了毛喉素的作用,提示该萜类化合物增加了向黏膜侧的电生性跨上皮氯转运。两种过程的半数最大激活浓度为1 - 3微摩尔,这与半数最大激活腺苷酸环化酶催化亚基所需的浓度相似。
