摘要

LSD1 is identified as an essential drug target, which is closely correlated to the development of several tumor types. In this work, on the basis of comprehensive analysis of the binding site of LSD1 and other FAD-dependent enzymes, a novel series of potent and selective LSD1 inhibitors were designed by incorporation of privileged indoline scaffold strategies. Representative compound 7e (LSD1; IC50 = 24.43 nM, selectivity over LSD2 and MAOs of >200- and 4000-fold) possessed selective antiproliferative activities against MV-4-11 cell lines. Further study indicates that 7e could activate CD86 expression (EC50 = 470 nM) and induce differentiation of AML cell lines. More importantly, compound 7e demonstrated an acceptable oral PK profile and good in vivo antitumor efficacy with a T/C value of 30.89% in an MV-4-11 xenograft mouse model. Collectively, this work provides a promising lead compound for the development of novel LSD1 inhibitors for the treatment of AML.
