Spectroscopic and X-ray studies of N-methylanabasine complexes with ZnX2 (X=Br, Cl)
摘要:
ZnX2 (X = Br, Cl) complexes with N-methylanabasine have been synthesized and characterized by elemental analysis and spectroscopic techniques. The complexes are formulated as [(C11H16N2)(2)ZnBr2] (1) and [(C11H16N2)(2)ZnCl2] (2) where C11H16N2 = N-methylanabasine. The X-ray structure of compound 1 is presented. It constitutes the first report on the crystal structure of the metal complex with anabasine or its derivative acting as a ligand. It shows that two N-methylanabasine units and two bromide anions form a tetrahedral coordination around the Zn2+ cation. (C). 2011 Elsevier B.V. All rights reserved.

tropinone were fed to transformed root cultures of Nicotianarustica and/or a Brugmansia candida × aurea hybrid. These cultures were made by the transformation of the relevant plant species with Agrobacterium rhizogenes . A number of the metabolites, notably those showing a relatively modest alteration in the N -alkyl substituent, were metabolized in vivo to form homologues of the normal alkaloids biosynthesized
摘要 将一系列 N-甲基腐胺和托品酮的类似物喂入转化的 Nicotiana rustica 和/或 Brugmansia candida × aurea 杂种的根培养物。这些培养物是通过用发根农杆菌转化相关植物物种而制成的。许多代谢物,特别是那些在 N-烷基取代基中表现出相对温和改变的代谢物,在体内代谢形成由这些根生物合成的正常生物碱的同系物。这些产品通过 GC/MS 进行鉴定并与一些合成参考材料进行比较。N-烷基取代基大小发生重大变化的类似物根本没有代谢。在 N. rustica 培养物中,以 1 mM 喂食的类似物显着影响了正常生物碱的分布,在存在 N-n-丙基腐胺的情况下,发现尼古丁最多减少 4 倍。吡咯烷系列和哌啶系列的生物碱之间的比例也受到影响。相比之下,念珠菌×金黄色混合培养物中 1 mM 类似物的存在不会抑制或显着干扰正常生物碱谱的积累。讨论了使用这些培养物从简单的前体制造复杂的新产品的潜力。

selectively at the nitrogen atom of the pyridine ring. The oxidation of N-methylanabasine under similar conditions gives a mixture of stereo-isomeric N-oxides at the piperidinenitrogen atom, their ratio depending on the reagent used. The oxidation of anabasine by TBHP— MoCl5 or MCPBA is accompanied by dehydrogenation and results in anabaseine N-oxide. The reactions of anabasine and anabaseine pyridine

The invention concerns novel anabaseine-related compounds that are useful in treating certain degenerative neural diseases such as Alzheimer's and Parkinson's which apparently involve decreased function of cerebral cortical nicotinic receptors. The compounds showed activity in both in vitro and in active and passive active avoidance studies in animal models. An exemplary active compound is a 3-substituted 2,4-dimethoxy-benzylidene anabaseine.

N-Phenacyl salts of acetyl-, benzoyl-, and methylanabasine were synthesized for the first time. Their reactions with unsaturated carbonyl compounds of the ethylene and acetylene series and acrylonitrile were studied. Methods for the synthesis of 6- and 8-(2-piperidyl)indolizines were developed.
