The pure four diastereomers (11a-d) of trans-benzyl (1-((4-(2-aminocyclopropyl)phenyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate hydrochloride 11, previously described by us as LSD1 inhibitor, were obtained by enantiospecific synthesis/chiral HPLC separation method. Tested in LSD1 and MAO assays, 11b (S,1S,2R) and 11d (R,1S,2R) were the most potent isomers against LSD1 and were less active against MAO-A and practically inactive against MAO-B. In cells, all the four diastereomers induced Gfi-1b and ITGAM gene expression in NB4 cells, accordingly with their LSD1 inhibition, and 11b and 11d inhibited the colony forming potential in murine promyelocytic blasts.
反式苄基（1-((4-(2-氨基环丙基)phenyl)氨基)-1-氧代-3-苯基丙烷-2-基）氨基甲酸酯盐酸盐11的四种纯非对映异构体（11a-d），我们之前将其描述为LSD1抑制剂，通过对映体特异性合成/手性HPLC分离方法获得。在LSD1和MAO测定中进行测试，11b（S,1S,2R）和11d（R,1S,2R）是针对LSD1最有效的异构体，对MAO-A活性较低，对MAO-B几乎无活性。在细胞中，所有四种非对映异构体均诱导NB4细胞中Gfi-1b和ITGAM基因表达，与其对LSD1的抑制作用一致，并且11b和11d抑制小鼠早幼粒细胞的集落形成潜能。
