FAD-dependent enzyme mono-amine oxidase A (MAO-A). Although a wide range of irreversibleinhibitors of LSD1 have been reported with activities in the low nanomolar range, this work represents one of the first reported examples of a reversible small molecule inhibitor of LSD1 with clear SAR and selectivity against MAO-A, and could provide a platform for the development of more potentreversibleinhibitors. Herein
Unprecedented CuI/CuII‐assisted tandem catalysis allowing an Ullmann/Chan–Evans–Lam sequence was achieved. This three‐component, one‐pot reaction triggered by a change in the oxidation state of the metal leads to the selective N1,N3‐diarylation of 3‐aminopyrazole. This new method should be a valuable tool for small‐molecule drug discovery that requires suitable regio‐ and/or chemoselective strategies
前所未有的Cu I / Cu II辅助串联催化,实现了Ullmann / Chan–Evans–Lam序列。这种由金属的氧化态变化引发的三组分一锅法反应导致3-氨基吡唑的选择性N 1,N 3-二芳基化。这种新方法应该是发现小分子药物的有价值的工具,它需要适当的区域和/或化学选择策略来使含氮杂环的N-芳基化。
