  由取代的抗氧化剂的Nrf2信号的激活反式茋

  摘要：

  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

  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.

  本发明涉及替代的stilbenes和dienones，表现出意外的双重活性，作为NFKB的抑制剂和Nrf2的激动剂。特别是，这些化合物展现了双重活性，已经发现这些化合物在治疗某些化妆品应用以及在使需要的主体的皮肤和其他角质组织恢复活力和美化方面特别有用。本文披露了化妆品组合物以及使用所述组合物与其他成分结合的方法。

  The present invention relates to substituted stilbenes and dienones which exhibit unexpected dual activity, as inhibitors of NFκB and as agonists (activators) of Nrf2. In particular, these compounds show dual activity and makes them particularly useful in the treatment of inflammation, including chronic inflammation and a number of related chronic disease states and conditions, including neurological diseases, including Alzheimer's, Alzheimer's prodrome and mild cognitive impairment, and other diseases and conditions, such as Parkinson's disease, depression, bipolar disorders and autism spectrum disorders. Compounds, pharmaceutical compositions and methods of treatment are described.

  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
