We have developed a high-efficiency and practical Cu-catalyzed cross-coupling to directly construct versatile α-aryl-esters by utilizing readily available aryl bromides (or chlorides) and malonates. These gram-scale approaches occur with turnovers of up to 1560 and are smoothly conducted by the usage of a low catalyst loading, a new available ligand, and a green solvent.

This invention is directed to novel oxamyl dipeptide ICE/ced-3 family inhibitor compounds. The invention is also directed to pharmaceutical compositions containing these compounds, as well as to the use of such compositions in the treatment of patients suffering inflammatory, autoimmune and neurodegenerative diseases, for the prevention of ischemic injury, and for the preservation of organs that are to undergo a transplantation procedure.

domain containing protein 1 (FAHD1) acts as oxaloacetate decarboxylase in mitochondria, contributing to the regulation of the tricarboxylic acid cycle. Guided by a high-resolution X-ray structure of FAHD1 liganded by oxalate, the enzymatic mechanism of substrate processing is analyzed in detail. Taking the chemical features of the FAHD1 substrate oxaloacetate into account, the potential inhibitor structures
含有 FAH 结构域的蛋白 1 (FAHD1) 在线粒体中充当草酰乙酸脱羧酶,有助于三羧酸循环的调节。以草酸配体的 FAHD1 的高分辨率 X 射线结构为指导,详细分析了底物处理的酶促机制。考虑到 FAHD1 底物草酰乙酸的化学特征,推断出潜在的抑制剂结构。药物样支架的合成提供了第一代 FAHD1 抑制剂,其活性在低微摩尔 IC 50范围内。研究揭示了与底物竞争结合金属辅因子的结构,以及支架,它们可能具有与 FAHD1 的新结合模式。

modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.
