Abstract

The invention relates to a preparation method for a cyclopropylamine spiro(hetero)cyclic compound and a composition containing the same, and application of the compound and the composition as an inhibitor for human lysine-specific demethylase (LSD1). The inhibitor is the cyclopropylamine spiro(hetero)cyclic compound as shown in a formula (I) which is described in the specification, or a pharmaceutically acceptable salt, predrug, solvate, polymorphic crystal or stable isotope derivative thereof. The compound can be used for treating or preventing diseases related to human lysine-specific demethylase, e.g., cancers and nerve diseases.

Description

technical field [0001] The invention relates to a cyclopropylamine spiro (hetero) ring compound, its isomer, prodrug or pharmaceutically acceptable salt, stable isotope derivative, its pharmaceutical composition, preparation method and application. Background technique [0002] Human lysine specific demethylasel (LSD1) is a member of the amine oxidase family. With the participation of flavin adenine dinucleotide (FAD), LSD1 can specifically remove histone H3 Dimethyl and monomethyl modifications on fourth (H3K4) and ninth (H3K9) lysine residues. LSD1 can also remove methylation modifications on some other non-histone substrates, such as p53 and DNMT1. LSD1 has a variety of biological functions, mainly including promoting tumor proliferation, inhibiting energy metabolism, promoting fat synthesis, inhibiting lipolysis and regulating cell differentiation. Therefore, LSD1 is a potential drug target for the prevention and treatment of various diseases. [0003] LSD1 is overexp...
