  Neurotrophic sesquiterpene-neolignans from magnolia obovata: structure and neurotrophic activity

  摘要：

  Novel sesquiterpene-neolignans, audesobovatols A (1) and B (2) cudesmagnolol (3), eudeshonokiols A (4) and B (5), clovanemagnolol (6), and caryolanemagnolol (7), have been isolated from the bark of Magnolia obovata. Their structures were elucidated to be sesquiterpenes (eudesmol, 4,4,8-trimethyltricyclo [6.3.1.0(2,5)] dodecane-1,9-diol, and clovanediol) combined through ether bond with neolignans such as obovatol, honokiol, and magnolol on the basis of spectral data, degradation, and/or synthesis. Compounds I, 6, and 7 were found to exhibit interesting neurotrophic activity on a neuronal cell culture system derived from fetal rat hemisphere.

  摘要：

  使用能促进神经元生长的小分子是再生科学的一种前景广阔的方法。根据这一思路，我们开发了天然产物卡利叶马钱子醇和氯凡马钱子醇的短合成或模块化合成，这些小分子之前已被证明能促进神经元生长并诱导胆碱乙酰转移酶活性。假定的生物合成途径可能导致这些分子在自然界中的组装，这些途径为实验室合成提供了指导，使这两种天然产物的制备只需两个步骤。通过合成这两种化合物的单一对映体，我们研究了氯凡马诺醇促进胚胎海马和大脑皮层神经元生长的能力。研究表明，氯凡诺洛尔是一种有效的神经营养剂，在 10 nM 的浓度下就能促进神经元的生长。

  Separate short and modular syntheses of the isomeric natural products caryolanemagnolol and clovanemagnolol have been achieved starting from commercially available (-)-caryophyllene. The postulated biosynthetic pathways guided the syntheses of the neuro regenerative small molecules allowing their assembly in as few as two steps.

  The use of small molecule surrogates of growth factors that directly or indirectly promote growth represents an attractive approach to regenerative medicine. With synthetic access to clovanemagnolol, a small molecule initially isolated from the bark of the Bigleaf Magnolia tree, we have examined the small molecule's ability to promote growth of embryonic hippocampal and cortical neurons in serum-free medium. Comparisons with magnolol, a known promoter of growth, reveals that clovanmagnolol is a potent neurotrophic agent, promoting neuronal growth at concentrations of 10 nM. In addition, both clovanemagnolol and magnolol promote growth through a biphasic dose response. (C) 2011 Elsevier Ltd. All rights reserved.
