Description

technical field [0001] The invention relates to a class of 3-position double β-carboline base compounds and pharmaceutically acceptable salts thereof, a preparation method thereof, a pharmaceutical composition of such compounds, and an application thereof in the preparation of antitumor drugs; belonging to medical technology field. Background technique [0002] Jiang et al. (2002) reported the design and synthesis of bis-3,4-dihydro-β-carbolines and bis-β-carboline compounds linked by a methylene bridge at the 1-position, and found that such bis-β-carbolines Alkali is cytotoxic to the L1210 cell line. [0003] Cook et al. (2005, 2010) reported the synthesis of bis-β-carbolines linked by 6-alkyne bridges, and subsequently confirmed that such bis-β-carboline bases are sensitive to benzodiazepine receptors (Bz) and γ-aminobutyric acid Acid (GABA) receptors have good affinity. [0004] Winckler et al. (2010) designed bis-3,4-dihydro-β-carboline and bis-β-carboline compounds c...
