摘要

鞘翅目昆虫与昆虫关系密切，但我们对它们通常独特的化学性质了解有限。在这里，我们报告了表皮脂质硝烷的鉴定结果，它代表了一类新型的表皮脂质。硝基烷（4）是一种由七个异戊二烯单元组成的不规则萜烯，由一个二萜核心构成，该核心由一个本身被预炔化的香叶基修饰。观察到的[46+(22+11)1]-三萜结构以前从未报道过。

Nitidane: An Irregular Prenylated Diterpene from the Cuticle of the Springtail Heteromurus nitidus

Collembola are closely related to insects, but our knowledge of their often unique chemistry is limited. Here we report the identification of the epicuticular lipid nitidane, representing a novel class of epicuticular lipids. Nitidane (4) is an irregular terpene consisting of seven isoprene units, made up of a diterpene core that is modified by a geranyl moiety that is itself prenylated. The observed [4⁶+(2²+1¹)¹]-terpene structure has not been reported before.

期刊介绍： The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained. Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin. When new compounds are reported, manuscripts describing their biological activity are much preferred.
