Panaxynol(PNN)is a kind of polyacetyl alcohol compound,which is distributed in many plants and has various effects,such as anti-cancer,antibacterial,sedative,analgesic,antihypertensive,anti-inflammatory,and neuroprotective effects.With the development of research,in recent years,it has been found that panaxynol has a wide range of pharmacological effects on cardiovascular system,nervous system,digestive system and immune system,and can be used for the treatment of coronary heart disease,angina pectoris,antithrombosis,diabetes,inflammatory diseases,aging and oxidation,malignant tumors and other diseases.Among them,the effects of panaxynol on tumor cells mainly include inhibiting tumor cell growth,inducing tumor cell apoptosis,killing tumor cells and blocking tumor cell metabolism.At the same time,ginseng alkynol has strong cell affinity and high sensitivity to tumor cells,which leads to its obvious inhibitory and killing effect on malignant tumor cells.This paper briefly reviews the research progress of panaxynol in tumor treatment.
