Abstract

The invention discloses an application of piperlongumine in the preparation of anti-bacterial and anti-inflammatory drugs. By performing RNA-seq transcriptome analysis for the cells of people infectedwith bacteria, a list of drug candidates with functions of antisepsis and anti-inflammation can be obtained on account of analysis methods of co-expression pathway and drug gene aggregation, whereinthe list comprises a plurality of marketed drugs with anti-bacterial and anti-inflammatory effects, the piperlongumine not discovered to have anti-bacterial and anti-inflammatory effects is right in the list. Therefore, the piperlongumine can be used in the preparation of anti-bacterial and anti-inflammatory drugs.

Description

technical field [0001] The invention relates to new uses of medicines, in particular to new uses of perylene amide, specifically the application of perylene amide in the preparation of antibacterial and anti-inflammatory drugs, and belongs to the field of biomedicine. Background technique [0002] Piperlongumine (Piperlongumine) is a natural alkaloid compound present in Piper longumine, which has anti-malignant tumor, anti-platelet aggregation, regulation of blood lipid metabolism, anti-Parkinson's disease, promotion of melanocyte proliferation, anti-inflammation, It has antifungal effects, but has no obvious toxic and side effects on normal cells, tissues, and organs (see Li Lianjian, Chen Chunlei. The pharmacological mechanism and research progress of pinionamide[J]. Hainan Medicine, 2015(14): 2113- 2115.). [0003] Perylene amide can increase the level of reactive oxygen species (ROS) in cells and selectively kill cancer cells. It inhibits gastric cancer by inhibiting T...
