摘要:N,N '-二酰肼(r 1 Co-Nr 3-Nr 4-Cor 2 )是一类在化学和生物学领域具有广泛应用的小分子.它们在结构上是独特的,因为它们的两个酰胺基团通过 N-N 单键连接,因此,这些分子可以以八种不同的异构形式存在.其中四种是由 C-N 键产生的酰胺异构体 [反式-反式 (T-T),反式-顺式 (T-C),顺式-反式 (C-T) 和顺式-顺式 (C-C)]限制旋转.此外,由于n-N键限制旋转,这些酰胺异构体中的每一种都可以以两种不同的异构体形式存在,特别是当r 3和r 4基团相对较大时.在此,我们结合溶液核磁共振波谱,X射线晶体学和密度泛函理论计算,系统地研究了 55 N,N'-二酰基肼的构象.我们的数据表明,当氮原子上的取代基r 3和r 4都是氢时.这些分子更喜欢扭曲的反式-反式 (T-T) (>90%) 几何形状 (H-N-C=o ∼ 180°),而n-烷基化和n

摘要:The subject invention relates in part to the oral administration of ecdysteroids for controlling subterranean termites. Preferred ecdysteroids for use according to the subject invention are ecdysone, certain ecdysone analogs, and 20-hydroxyecdysone, for example. In some preferred embodiments, one or more of these compounds is used in a termite bait in combination with one or more chitin synthesis inhibitors. Thus, the subject invention also relates in part to controlling termites by the use of a chitin synthesis inhibitor (CSI), such as hexaflumuron and/or noviflumuron, together with an ecdysteroid (and analogs thereof) or molt-accelerating compound (MAC), such as halofenozide. The subject invention also relates to mixtures comprising these two active ingredients. The MAC/ecdysteroid analog induces a preliminary molting event in termite workers (they could not complete the molting), which then allows the CSI to further disrupt the molt and cause mortality. The combination of these active ingredients, causing accelerated molting together with inhibition of chitin synthesis, is surprisingly shown herein to enhance activity against termites, as compared to either group of compounds alone.
