生物活性方面,7-甲氧基罗勒内酯(7-O-甲氧基罗勒内酯)是一种可以从迷迭香中分离得到的酚类二萜。它能够抑制PEPCK和G6Pase启动子的cAMP反应。
The new diterpenes canariquinone (9), rosmaquinone (10), and 11-acetoxycarnosic acid (6), together with the already known 7-ethoxyrosmanol (1), 7-methoxyrosmanol (2), and rosmanol (3), were isolated from the flowers of Salviacanariensis. The structure of the new substances was established by a combination of chemical and spectroscopic means. Reaction of galdosol (4), isolated from the aerial part of the same plant, with diazomethane, unexpectedly gave the new homoditerpenes 15 and 16, the structures of which were determined by spectroscopic methods. A mechanism accounting for the formation of these substances is suggested. Keywords: abietane diterpenes, Salvia, Labiatae, antibiotic activity, galdosol reactivity.
