  Synthesis, biological activity and mechanistic insights of 1-substituted cyclopropylamine derivatives: A novel class of irreversible inhibitors of histone demethylase KDM1A

  摘要：

  Histone demethylase KDM1A (also known as LSD1) has become an attractive therapeutic target for the treatment of cancer as well as other disorders such as viral infections. We report on the synthesis of compounds derived from the expansion of tranylcypromine as a chemical scaffold for the design of novel demethylase inhibitors. These compounds, which are substituted on the cyclopropyl core moiety, were evaluated for their ability to inhibit KDM1A in vitro as well as to function in cells by modulating the expression of Gfi-1b, a well recognized KDM1A target gene. The molecules were all found to covalently inhibit KDM1A and to become increasingly selective against human monoamine oxidases MAO A and MAO B through the introduction of bulkier substituents on the cyclopropylamine ring. Structural and biochemical analysis of selected trans isomers showed that the two stereoisomers are endowed with similar inhibitory activities against KDM1A, but form different covalent adducts with the FAD co-enzyme.

• Alkoxydiaminophosphine Ligands as Surrogates of NHCs in Copper Catalysis

  A family of phosphine ligands containing a five‐membered ring similar to the popular N‐heterocyclic carbene ligands and an alkoxy third substituent has been developed. These alkoxydiaminophosphine ligands (ADAP) can be generated in one pot and reacted with a copper(I) source leading to the high yield isolation of complexes [(ADAP)CuX]2 (X=Cl, Br). The dinuclear nature of these compounds has been established

  已开发出一个含有五元环的膦配体，该环类似于流行的N杂环卡宾配体，并带有一个烷氧基第三取代基。这些烷氧基二氨基膦配体（ADAP）可以在一个锅中生成，并与铜（I）源反应，从而导致复合物[（ADAP）CuX] 2的高产率分离。（X ＝ Cl，Br）。这些化合物的双核性质已通过X射线研究和DOSY实验确定。对这些配合物从重氮化合物到CH键（烷烃，芳烃），烯烃或NH键的卡宾转移反应的催化性能的筛选，以及在CuAAC或腈转移反应中的性能至少相似（如果不是更好的话），则比他们的（NHC）CuCl类似物好，这些易于调节的ADAP配体为铜催化打开了一个新窗口。
