Abstract

The present invention relates to the field of medicine, in particular to a medical use of psoralenchalcone and its analogues, which are compounds with the structure of formula (I), or their pharmaceutical Acceptable salts, tautomers, stereoisomers or prodrugs above: Among them, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 each independently selected from the group consisting of hydrogen, ORa, OCOORa, OCONRaR b 、OSO 2 Ra and OSO 3 Ra; the Ra and R b each independently selected from the group consisting of hydrogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, substituted or unsubstituted C2-C12 alkynyl, substituted or unsubstituted C6-C30 aryl group, and substituted or unsubstituted C1-C30 heteroaryl group; the psoralen chalcone and its analogues are used to prepare medicines or health care products for promoting vascular endothelial repair and / or angiogenesis.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the medical application of psoraleachalcone and its analogues. Background technique [0002] Vascular endothelial injury is the initiating factor of atherosclerosis, and vascular injury may also lead to extremity ischemia, coronary heart disease and other diseases. Mature vascular endothelial cells are limited by proliferation and division, and their function of repairing damaged endothelium is limited. Recent studies have found that there are endothelial progenitor cells (Endothelial Progenitor Cells, EPCs) in the peripheral blood in vivo, which can differentiate into endothelial cells and further repair damaged blood vessels or participate in angiogenesis. Endothelial progenitor cells are precursor cells that can specifically home to the injured area and directly differentiate and proliferate into vascular endothelial cells (ECs). After birth, EPCs participate in angiogenesis and have...
