  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.

  readily prepared by rhodium-catalyzed cyclopropanation of alkenes with aryldiazoacetates and styryldiazoaceates, in which the ester functionality is either trimethylsilylethyl (TMSE) or trichloroethyl (TCE). By having labile protecting groups on the ester, chiral triarylcyclopropane carboxylate ligands were conveniently prepared. The asymmetric induction during cyclopropanation is dependent on the

  通过用芳基重氮乙酸酯和苯乙烯基二重氮酸酯对烯烃进行铑催化的环丙烷化，可以轻松制备高度官能化的环丙烷羧酸酯，其中酯官能度为三甲基甲硅烷基乙基（TMSE）或三氯乙基（TCE）。通过在酯上具有不稳定的保护基，可以方便地制备手性三芳基环丙烷羧酸酯配体。环丙烷化过程中的不对称诱导取决于酯基和手性四羧酸四氢吡啶鎓催化剂的性质。脯氨酸盐催化剂Rh 2（S -DOSP）4是TMSE重氮酯与苯乙烯不对称分子间环丙烷化的最佳催化剂，而Rh 2（R -BPCP）4 是TCE重氮酯的最佳催化剂。
