  Identification of GDC-0810 (ARN-810), an Orally Bioavailable Selective Estrogen Receptor Degrader (SERD) that Demonstrates Robust Activity in Tamoxifen-Resistant Breast Cancer Xenografts

  摘要：

  Approximately 80% of breast cancers are estrogen receptor alpha, (ER-a) positive, and although women typically initially respond, well to antihormonal therapies such as tamoxifen and aromatase inhibitors, resistance often emerges. Although a variety of resistance mechanism may be at play in this state, there is evidence that in many cases the ER still plays a central role, including mutations in the ER leading to constitutively active receptor. Fulvestrant is a steroid-based, selective estrogen receptor degrader., (SEED) That both antagonizes and degrades ER-alpha and is active in patients who have progressed on antihormonal agents. However, fulvestrant suffers from poor pharmaceutical properties and must be administered by intramuscular injections that limit the total amount of drug that can be administered and hence lead to the potential for incomplete receptor blockade. We describe the identification and characterization of a series of small-molecule, orally bioavailable SERDs, which are potent antagonists and degraders of ER-alpha and in which the ER-alpha degrading properties were prospectively optimized. The lead compound 111 (GDC-0810 or ARN-810) demonstrates robust activity in models of tamoxifen-sensitive and tamoxifen-resistant breast cancer, and is currently in clinical trials in women with locally advanced or metastatic estrogen receptor-positive breast cancer.

• Decarboxylative Cross-Electrophile Coupling of <i>N</i>-Hydroxyphthalimide Esters with Aryl Iodides

  A new method for the decarboxylative coupling of alkyl N-hydroxyphthalimide esters (NHP esters) with aryl iodides is presented. In contrast to previous studies that form alkyl radicals from carboxylic acid derivatives, no photocatalyst, light, or arylmetal reagent is needed, only nickel and a reducing agent (Zn). Methyl, primary, and secondary alkyl groups can all be coupled in good yield (77% ave

  available catalysts based on inexpensive, environmentally benign base metals are therefore strongly needed. Furthermore, expanding the toolbox of methods based on photoredox catalysis will facilitate the discovery of new light-mediated transformations. This article details the use of a simple copper complex which, upon activation with blue light, can initiate a broad range of radical reactions.

  有机转化大致可分为四类，包括阳离子反应、阴离子反应、周环反应和自由基反应。尽管几十年来人们都知道最后一类可以提供非常有效的合成途径，但它长期以来一直受到有毒试剂需求的阻碍，这在很大程度上限制了它对化学合成的影响。随着产生自由基物质的新概念的引入，这种情况已经结束，光氧化还原催化——它仅依赖于使用可在可见光照射下激活的催化剂——当然是最有效的一种。最先进的催化剂主要依赖于钌和铱络合物以及有机染料的使用，这仍然在很大程度上限制了它们在化学过程中的广泛应用：因此，迫切需要基于廉价、环境友好的贱金属的替代现成催化剂。此外，扩展基于光氧化还原催化的方法工具箱将有助于发现新的光介导转化。本文详细介绍了简单的铜络合物的使用，该络合物在蓝光激活后可以引发广泛的自由基反应。

Further, the preferential activation of alkyl vs aryl halides by ArNi(I) complexes as well as the high affinity of ArNi(II) for secondary over tertiary C-centered radicals explains the lack of undesired homo- and direct coupling products (Ar-Ar
