Abstract

The invention discloses a water-soluble perylene bisimide compound and an application of a water-soluble perylene bisimide compound for preparing DNA intercalators, inhibiting cancer cell growth and resisting tumors, belonging to the technical field of biological drug chemical synthesis. A cationic amino functional group is introduced into perylene derivatives and single perylene systems, so that the water solubility is greatly improved, the amino functional group is bound to light stability of perylene derivatives, and a series of novel water-soluble perylene bisimide compounds are obtained. The synthetic compound can be effectively embedded into DNA double helix base pairs of the cell nucleus and can serve as a DNA intercalator. The synthetic compound has a planar rigid structure, can be specifically enriched on a fixed tissue cell nucleus, is high in fluorescence intensity and easy in fluorescence imaging and can be compared favorably with commercial cell nucleus dyes DAPI. The synthetic compound can effectively inhibit growth of cancer cells such as U2OS, HCT116, HeLa and AGS, has an obvious antitumor effect and can be applied to preparing antitumor drugs.

Description

technical field [0001] The invention belongs to the technical field of biopharmaceutical chemical synthesis, and particularly relates to a water-soluble perylene imide compound and its application as a DNA intercalation agent in anti-cancer cells and tumors. Background technique [0002] Perylene and its derivatives have good light, thermal and chemical stability, almost 100% fluorescence quantum yield, narrow fluorescence emission peak, can be separated from cell background fluorescence (395-479nm) and excellent dyeing performance. It has been widely used in the fields of organic optoelectronic devices, laser dyes and bioluminescent probes. [0003] Intercalator refers to the reversible interaction between polycyclic aromatic hydrocarbon small molecule substances and DNA. This type of molecule is small in size, in an electron-deficient state, and has a certain planar rigidity. It can be inserted between two stacked base pairs of DNA. The insertion process leads to the heli...
