• Synthesis of 2-phenylnaphthalenes from styryl-2-methoxybenzenes

  A new simple and efficient method for the synthesis of 2-phenylnaphthalenes from electron-rich 1-styryl-2-methoxybenzenes has been described. The reaction proceeds via TFA catalyzed C-C bond cleavage followed by intermolecular [4+2]-Diels-Alder cycloaddition of an in situ formed styrenyl trifluoroacetate intermediate. The quantum chemical calculations identified the transition state for the cycloaddition

  已经描述了一种从富电子的1-苯乙烯基-2-甲氧基苯合成2-苯基萘的简单而有效的新方法。该反应通过TFA催化的CC键裂解进行，然后原位形成的苯乙烯基三氟乙酸酯中间体的分子间[4 + 2] -Diels-Alder环加成反应。量子化学计算确定了环加成反应的过渡态，并有助于追踪反应机理。该方法已被有效地用于合成菲骨架和基于萘的强效选择性ER-β激动剂。

  The present invention relates to substituted stilbenes and dienones which exhibit unexpected dual activity, as inhibitors of NFKB and as agonists (activators) ofNrf2. In particular, these compounds show dual activity and it has been discovered that these compounds are particularly useful in the treatment of certain cosmetic applications and in rejuvenating and beautifying skin and other keratinous tissue of a subject in need. Cosmetic compositions and methods of using said compositions in combination with other components are disclosed herein.

  is the issue of selectivity. In the present study, substituted trans stilbenes were identified as activators of Nrf2. These activators of Nrf2 are not highly electrophilic and therefore are unlikely to activate Nrf2 through covalent modification of Keap1. Dose-response studies demonstrated that a range of substituents on either ring of the trans stilbenes, especially fluorine and methoxy substituents

  Nrf2是cap'n'collar转录因子家族的成员，是II期排毒和抗氧化基因以及抗炎和神经保护基因的主要调节剂。在许多慢性疾病中炎症和氧化应激的重要性支持了抗氧化剂Nrf2信号转导可能具有治疗潜力的概念。许多Nrf2激活剂已进入临床试验。Nrf2与它的结合伴侣Keap1结合存在于胞质溶胶中，Keap1是一种富含硫醇的氧化还原传感蛋白。响应于氧化和亲电子应力，Keap1的选定半胱氨酸残基被修饰，从而将Keap1锁定在Nrf2-Keap1复合物中，并使新合成的Nrf2进入细胞核。激活Nrf2的多种化学物质，包括多种天然产物，是亲电试剂，通常通过迈克尔加成来修饰Keap1，从而导致Nrf2激活。作为Keap1的亲电子共价修饰剂的Nrf2活化剂的设计，一个需要关注的问题是选择性问题。在本研究中，替代反式斯蒂芬苯酯被鉴定为Nrf2的激活剂。这些Nrf2激活剂不是高度亲电的，因此不太可能通过Keap
• Quinone reductase induction activity of methoxylated analogues of resveratrol
  作者：W. Zhang、M.L. Go

  DOI：10.1016/j.ejmech.2006.12.012

  日期：2007.6

  Agents that induce the activity of phase II enzymes play an important role in intervening with the carcinogenic process at the initiation stage. Resveratrol is well known for its chemopreventive activity against major stages of carcinogenesis. In this study, several methoxylated analogues of resveratrol were synthesized and evaluated for their ability to induce the activity of the phase H enzyme quinone reductase (QR). Methoxy groups serve to increase lipophilicity and improve metabolic stability. Compared to resveratrol, analogues with ortho-metboxy substituents were found to be more potent inducers of QR and to exert their activity in a qualitatively different manner. The greater induction activities associated with these stilbenoids serve as a useful starting point for the design of improved chemopreventive agents. (c) 2007 Elsevier Masson SAS.
